When the maximum number of parallel transactions has been reached and the resource changes its state, then the server MUST NOT start yet another transaction, but wait for the running attempts to fail or complete first. For the best-effort and eventual-consistency goals, the server also SHOULD NOT try to get an outdated representation to the client anyway. So, besides the issue raised in ticket #242 and the ongoing congestion control work, I think this ticket can be closed. -- ----------------------------------+---------------------------------------- Reporter: hartke@… | Owner: draft-ietf-core-observe@… Type: protocol enhancement | Status: closed Priority: minor | Milestone: post-WGLC-1 Component: observe | Version: observe-05 Severity: In WG Last Call | Resolution: wontfix Keywords: | ----------------------------------+---------------------------------------- Ticket URL: core From zach@sensinode.com Tue Sep 4 13:15:27 2012 Return-Path: X-Original-To: core@ietfa.amsl.com Delivered-To: core@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id D5FBC21E8082 for ; Tue, 4 Sep 2012 13:15:27 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -1.74 X-Spam-Level: X-Spam-Status: No, score=-1.74 tagged_above=-999 required=5 tests=[BAYES_20=-0.74, RCVD_IN_DNSWL_LOW=-1] Received: from mail.ietf.org ([64.170.98.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id q8sDTUGRJs5F for ; Tue, 4 Sep 2012 13:15:27 -0700 (PDT) Received: from auth-smtp.nebula.fi (auth-smtp.nebula.fi [217.30.180.105]) by ietfa.amsl.com (Postfix) with ESMTP id BB04721E8084 for ; Tue, 4 Sep 2012 13:15:26 -0700 (PDT) Received: from [192.168.1.103] (188-67-92-168.bb.dnainternet.fi [188.67.92.168]) (authenticated bits=0) by auth-smtp.nebula.fi (8.13.8/8.13.4) with ESMTP id q84KFMDg015612 for ; Tue, 4 Sep 2012 23:15:23 +0300 From: Zach Shelby Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: quoted-printable Date: Tue, 4 Sep 2012 23:15:22 +0300 Message-Id: To: "core@ietf.org WG" Mime-Version: 1.0 (Apple Message framework v1084) X-Mailer: Apple Mail (2.1084) Subject: [core] IPSO Application Framework -04 X-BeenThere: core@ietf.org X-Mailman-Version: 2.1.12 Precedence: list List-Id: "Constrained RESTful Environments \(CoRE\) Working Group list" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 04 Sep 2012 20:15:28 -0000 FYI a new version of the IPSO Application Framework -04 has now been = made available for download.

This draft is a work item of the Constrained RESTful Environments Working = Group of the IETF. Title : Observing Resources in CoAP Author(s) : Klaus Hartke Filename : draft-ietf-core-observe-06.txt Pages : 27 Date : 2012-09-06 Abstract: CoAP is a RESTful application protocol for constrained nodes and networks. The state of a resource on a CoAP server can change over time. This document specifies a simple protocol extension for CoAP that enables a server to replicate a resource state to interested clients. The protocol follows a best-effort approach when transmitting new resource states to a client, and provides eventual consistency between the state observed by the client and the actual resource state.

Andrew McGregor has agreed to step up in Cullen's place and co-chair CORE with Carsten. The IETF Secretariat should flip the bits some time on Friday, at which point the usual chairs alias, , will go to Andrew instead of to Cullen (as well as to Carsten, of course). And Cullen and Carsten will get Andrew acquainted with things and have him happily chairing you lot in no time. Many thanks to Cullen for having seen CORE through this far... and many thanks also to Andrew for agreeing to step in.

Probably using rt=3D for that query string parameter is confusing. Could = be better to change that to et=3D or type=3D in the query string?

The grouping concept adds to the confusion. Making the distinction up front in the document would be helpful. You may consider resource-type, endpoint-type, and group-type. In core-interfaces you do a first attempt and talk about resource-type for resources and for Function-sets. Althoug you keep the same parameter name rt, you seem to distinguish in the name space What to do with batches, which are heterogeneous, is another question. It would be nice if this is solved homogeneously over all documents. May be it is, and I just combine the wrong pieces of text. peter Zach Shelby schreef op 2012-09-07 11:38: > Esko, > > The rt= query string parameter in a Registration or Update sets the > "Endpoint Type", which gives some meaning to an endpoint semantically > in a backend system.

The characters are displayed on the client m/c as well. However, I would like to see the file being transferred to the final destination as it is just the way we see things happening in case of MIME attachments. I have seen people doing this kind of work in HTTP using some APIs provided by Apache web service (or something like that .. may be....not sure...I have not done myself).

I converted the txt document to word and edited the word document; that made my life easier. I changed the abstract to make clearer that the draft gives guidelines for interoperability intead of alternative designs. My comments on security are based on my sentiments and not on factual knowledge. Text was added on the basis of my understanding and may consequently be off the mark.

The definition of the four QoS level and the relative QoS field values is the following: - Level 1: The subject sends non-critical and critical notifications with low priority.

Dear List,

The current definition of the observe draft does not specify any mechani= sm for deciding in which order the server should send the notifications.&nb= sp;According to section 4.2:

“If there are multiple clients on the list of obs= ervers, the order in which they are notified is not defined; the server is = free to use any method to determine the order”.

My suggestion is that the draft should clearly define the delivery order= of the notifications. 

For instance, in e-emergency applications the notification of a critical= event must be prioritized to those observers in charge of reacting to it= =2E These nodes could also be interested only in being notified in a case a= critical event occurs. Furthermore, an alarm could be interested in being = notified only when a critical event occurs and when it ends. Instead, obser= vers that are used for monitoring purpose could be interested in receiving = all the notifications.

 Reasons:

-          Observers could have different delay= requirements.

-          The delay of a notification is stron= gly affected by the delivery order.

-          Observers could be interested in rec= eiving only some particular notifications.

-          The observe draft would add QoS supp= ort for timeliness and guarantee on-time delivery to clients interested in = it.

Requirements:

-          The server shoul= d be able to prioritize the delivery of notifications to observers requirin= g it.

-          The server shoul= d be able to distinguish which notifications send to a particular observer= =2E

Commonly, the server has not information about the clients. The server o= nly has information about the resource that is exposing. Therefore, the cli= ents should be able to require a priority level and to indicate which kind = of notifications they wish to receive.

 Propo= sal:

A notification should be classified as critical or non-critical. The ser= ver must be the only component that has the authority to make this decision= =2E

Four levels of QoS are proposed. The value of each level is specified us= ing the two most significant bits of the observe option value (QoS field)= =2E This modification affects only the requests sent by observers for regis= tering and the consequent response of the subject. The definition of the fo= ur QoS level and the relative QoS field values is the following:

-          Level 1: The sub= ject sends non-critical and critical notifications with low priority. The v= alue of the QoS field is 00.

-          Level 2: Both no= n-critical and critical notifications are sent with medium priority. The va= lue of the QoS field is 01.

-          Level 3: The sub= ject sends only critical notification with high priority. The value of the = QoS field is 10.

-          Level 4: The sub= ject notifies with the highest priority only the start and the end of a cri= tical state. The value of the QoS field is 11.

Should more than one observer require the same level, the subject should= order them following the order at which their requests arrived.

The client and the server must be able to negotiate the QoS level. A ser= ver, in fact, should have the faculty to reject or negotiate the demanded Q= oS. Should the server accepts the request, it replies with the observe opti= on containing the QoS value requested. The server expresses its willingness= to negotiate the QoS by replying with the offered QoS. Should the clients = accepts, it would send a response containing the offered QoS. The server ca= n reject the offer by ignoring it.

Benefits:

We run tests focused on evaluating the effects that this proposal has on= a WSN adopting the observe extension. The tests are done in a real WSN usi= ng TelosB motes. The requirements of the observe extension application are = those of an e-health network used for monitoring the cardiac rate of a pati= ent. The performance evaluation has been done in terms of delay, delivery r= atio and energy consumption.

-          The results conf= irm that the delivery order of a notification influence both the delay and = delivery ratio.

-          The first notifi= cations sent by a subject experience less delay and have a high delivery ra= tio.

-          The energy consu= mption of the subject is considerably reduced if observers are able to expr= ess the notification class of interest.

 This proposal and the experimental results are contained in a fort= hcoming paper to be presented at the IEEE WiMOB conference (8-10 October 20= 12). The tile of the paper is “Adding QoS Support For Timeliness To T= he Observe Extension Of CoAP”. It is not yet available in the IEEExpl= orer. However, I can send it to those interested.

However, it builds on a wrong premise. CoAP-observe does not deliver events. Its emphasis is on the state of a resource at some server and the copy of the state that a client has, not on the messages that are exchanged between the two. The goal is to have the copy be as consistent as possible with the original. This means that the copy should be updated as soon as possible when the resource state changes. While it's not a goal to guarantee that this update happens within a particular time span (quite the opposite is the case), it is a goal that this time span is kept as short as possible. One means to achieve this is not to try to get every resource state to the client, but just the latest. If prioritization of clients helps with this in some application scenarios, I think it would be worthwhile to consider. I'd be interested to see the evaluation of the presented example after updating it to the right model.

Hi,

Klaus:

I would provide new results as soon as I update the model and re-run the= experiments. I have to figure out how the observe premises could affect th= e model. Any comments or suggestions are very welcome.

From: core-bounces@ietf.org [mail= to:core-bounces@ietf.org] On Behalf Of Alessandro Ludovici=
Sent: Thursday, September 13, 2012 9:56 PM
To: core@ietf.org
Subject: [core] Delive= ry order of notifications in draft-ietf-core-observe-06

 

Dear List,

The current definition of the observe draft does not specify any m= echanism for deciding in which order the server should send the notificatio= ns. According to section 4.2:

“If there are multiple clients on the list of observers, the= order in which they are notified is not defined; the server is free to use= any method to determine the order”.

My suggestion is that the draft should clearly define the delivery= order of the notifications. 

For instance, in e-emergency applications the notification of a cr= itical event must be prioritized to those observers in charge of reacting t= o it. These nodes could also be interested only in being notified in a case= a critical event occurs. Furthermore, an alarm could be interested in bein= g notified only when a critical event occurs and when it ends. Instead, obs= ervers that are used for monitoring purpose could be interested in receivin= g all the notifications.

 Reasons:<= !-- o ignored -->

-          Observers could have different= delay requirements.

-          The delay of a notification is= strongly affected by the delivery order.

-          Observers could be interested = in receiving only some particular notifications.

-          The observe draft would add Qo= S support for timeliness and guarantee on-time delivery to clients interest= ed in it.

Requirements:

-          The server= should be able to prioritize the delivery of notifications to observers re= quiring it.

-          The server= should be able to distinguish which notifications send to a particular obs= erver.

Commonly, the server has not information about the clients. The se= rver only has information about the resource that is exposing. Therefore, t= he clients should be able to require a priority level and to indicate which= kind of notifications they wish to receive.

 Proposal:

A notification should be classified as critical or non-critical. T= he server must be the only component that has the authority to make this de= cision.

Four levels of QoS are proposed. The value of each level is specif= ied using the two most significant bits of the observe option value (QoS fi= eld). This modification affects only the requests sent by observers for reg= istering and the consequent response of the subject. The definition of the = four QoS level and the relative QoS field values is the following:

-          Level 1: T= he subject sends non-critical and critical notifications with low priority= =2E The value of the QoS field is 00.

-          Level 2: B= oth non-critical and critical notifications are sent with medium priority= =2E The value of the QoS field is 01.

-          Level 3: T= he subject sends only critical notification with high priority. The value o= f the QoS field is 10.

-          Level 4: T= he subject notifies with the highest priority only the start and the end of= a critical state. The value of the QoS field is 11.

Should more than one observer require the same level, the subject = should order them following the order at which their requests arrived.

The client and the server must be able to negotiate the QoS level= =2E A server, in fact, should have the faculty to reject or negotiate the d= emanded QoS. Should the server accepts the request, it replies with the obs= erve option containing the QoS value requested. The server expresses its wi= llingness to negotiate the QoS by replying with the offered QoS. Should the= clients accepts, it would send a response containing the offered QoS. The = server can reject the offer by ignoring it.

Benefits= :

We run tests focused on evaluating the effects that this proposal = has on a WSN adopting the observe extension. The tests are done in a real W= SN using TelosB motes. The requirements of the observe extension applicatio= n are those of an e-health network used for monitoring the cardiac rate of = a patient. The performance evaluation has been done in terms of delay, deli= very ratio and energy consumption.

-          The result= s confirm that the delivery order of a notification influence both the dela= y and delivery ratio.

-          The first = notifications sent by a subject experience less delay and have a high deliv= ery ratio.

-          The energy= consumption of the subject is considerably reduced if observers are able t= o express the notification class of interest.

 This proposal and the experimental results are contained in = a forthcoming paper to be presented at the IEEE WiMOB conference (8-10 Octo= ber 2012). The tile of the paper is “Adding QoS Support For Timelines= s To The Observe Extension Of CoAP”. It is not yet available in the I= EEExplorer. However, I can send it to those interested.

Alessandro Ludovici

In my opinion we need a window smaller than 256 seconds.

A possible solution would be to use an adaptive value, proportional to
the measured RTT. However there is no easy way to measure RTT,
especially for a CoAP server.

(based on dref= t-ietf-core-coap 11, point 4.5)

I believe for cons= trained nodes, it is possible to act differently depending on the type of t= he message. GET requests are safe and idempotent, so skipping deduplication= is not dangerous. At worst, a node answers request twice with different va= lue. Observe notifications have a sequence number, so it's possible to = discard duplicate notifications, that have sequence number smaller than the= newest received one (unless you need all responses). On the other hand POS= T requests should be deduplicated as throughly as possible, because every e= xecution of POST can change all further results.

So if you have only several slots for deduplication, yo= u can save them for tricky messages, and skip deduplication for safe ones.<= /div>

Hi Jeroen,

Introducing additional processing at t=
he server side always adds more complexity (more state info, more processin=
g). For conditional observe this includes storage of some additional state =
information (the condition and value) and condition checking. Conditional o=
bserve aims to reduce the number of times you transfer the state of the res=
ource. We implemented and evaluated this concept on Sky nodes having 48kB R=
OM. The advantage of being able to reduce the number of transmissions outwe=
ighs the slightly increased complexity.  
For your priority delivery, you will a=
lso have some additional overhead at the server side (you could even implem=
ent it as a condition indicating the priority level). It could be an extens=
ion to observe.
 
Priority delivery does not need to store state info at server-side. Th=
e list of observers can be organized following the priority delivery order=
=2E On the top of this list there would be the observers that the server ha=
ve to notify with the highest priority and so on. The only (small) extra-pr=
ocessing required is in the organization of the list. Furthermore, the clie=
nt expresses the desired priority level using the two most significant byte=
s the observe option value. The advantage of this is that we do not add ove=
rhead.
 
As Klaus suggested in its guide to observing resources (ht=
tp://svn.tools.ietf.org/svn/wg/core/observe/page1.html), a server could=
 expose more that on resource for storing the same state information. In a =
hearth rate monitoring application, a resource could expose only critical s=

 think this could be a good suggestion for reducing the number of transmiss=
ions. I will test it in my priority delivery model. However, there could be=
 situation where creating many resources could be wasteful and the use of c=

Another question about the prioritisation: how can you guarantee this =
delivery order in larger networks? In larger networks, it would better to l=
et an intermediary establish a single observation relationship to the const=

In this case, the intermediary would be in charge of the priority&n= bsp;delivery. Clients will only establish the observation with the intermed= iary.

To allow efficient 6lowpan compression of the multicast address (RFC6282), with stateless mode DAM=11 (ff02::GG) compressed down to 8 bits, an address in the range ff02::00-ff02::ff should be allocated.

Using multiple resources is not more wasteful than what you have described; the overhead is exactly the same. You just put your two bits in the request URI rather than the Observe Option. The same applies to -conditional-observe.

May be the relation of the con parameter to the “host relation” should be clarified. In sec 5.3 the con parameter is also mentioned to update the entry. In the case that the host:port changes completely, a new entry is required IMO. May be remove con from update? In the example of sec 5.3, the last line, ;ct=41;rt=”lightLux;if=”sensor” is identical to the 2nd line in the payload of the Registration example. This contradicts the last line of the intro of sec 5.32 Parameters (not Paremeters) that have not changed SHOULD NOT be included in an update. Better remove or change the last line in the Update example.

Section 4.4.2.3 of draft-ietf-lwig-guidance-02.txt contains some = recommendations on choosing message-IDs. If you do need to go random for some reason (e.g., no memory for keeping = per-peer counters even for EXCHANGE_LIFETIME), you could randomize the = source port (and, possibly, even the source IP address) as well, turning = the probability of a false positive from 1e-5 to 1e-9. By choosing a = different token, you can detect the false positive with very high = probability, but (for POST) I haven't really thought about recovery = strategies that would fully maintain "at-most-once" semantics. In many cases with very simple clients (which only ever send one kind of = request), the damage may just be a lost update (if this is for POST), or = simply getting a copy of old data (if this is for GET and the server = does buffer the old response, which many don't).

The rules for 0..255 (IETF Review) and for 2048..65535 (Designated Expert) are clear. However, reading RFC5226 further, it may be more appropriate to use a Specification Required for the 256..2047 range as Designated Expert was already decided for the 2048..65535 range. It might not make sense to have Designated Expert for two ranges. I propose the following text would be added to coap-12 Section 12.2, comments on the use of Specification Required, or on the text itself? {{{ The IANA policy for future additions to this registry is split into three tiers as follows. The range of 0..255 is reserved for options defined by the IETF (IETF Review). The range of 256..2047 is reserved for commonly used options with public specifications (Specification Required). The range of 2048..65535 is for all other options including private or vendor specific ones, which undergo a Designated Expert review to ensure that the option semantics are defined correctly. +---------------+------------------------+ | Option Number | Policy [RFC5226] | +---------------+------------------------+ | 0..255 | IETF Review | | 256..2047 | Specification Required | | 2048..65535 | Designated Expert | +---------------+------------------------+ }}} -- ----------------------------------+------------------------------------- Reporter: cabo@… | Owner: draft-ietf-core-coap@… Type: protocol enhancement | Status: new Priority: minor | Milestone: post-WGLC-1 Component: coap | Version: coap-09 Severity: In WG Last Call | Resolution: Keywords: | ----------------------------------+------------------------------------- Ticket URL: core From stokcons@xs4all.nl Mon Sep 24 01:12:49 2012 Return-Path: X-Original-To: core@ietfa.amsl.com Delivered-To: core@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 00B0C21F8543 for ; Mon, 24 Sep 2012 01:12:49 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: 2.594 X-Spam-Level: ** X-Spam-Status: No, score=2.594 tagged_above=-999 required=5 tests=[AWL=0.059, BAYES_05=-1.11, HELO_EQ_FR=0.35, HELO_EQ_NL=0.55, HOST_EQ_NL=1.545, J_CHICKENPOX_24=0.6, J_CHICKENPOX_44=0.6] Received: from mail.ietf.org ([64.170.98.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 7-kwy7LQcQkZ for ; Mon, 24 Sep 2012 01:12:48 -0700 (PDT) Received: from smtp-vbr11.xs4all.nl (smtp-vbr11.xs4all.nl [194.109.24.31]) by ietfa.amsl.com (Postfix) with ESMTP id 1767121F8540 for ; Mon, 24 Sep 2012 01:12:47 -0700 (PDT) Received: from roundcube.xs4all.nl (roundcube4.xs4all.net [194.109.20.200]) by smtp-vbr11.xs4all.nl (8.13.8/8.13.8) with ESMTP id q8O8CGAF096771; Mon, 24 Sep 2012 10:12:16 +0200 (CEST) (envelope-from stokcons@xs4all.nl) Received: from AMontpellier-556-1-284-62.w92-133.abo.wanadoo.fr ([92.133.132.62]) by roundcube.xs4all.nl with HTTP (HTTP/1.1 POST); Mon, 24 Sep 2012 10:12:16 +0200 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit Date: Mon, 24 Sep 2012 10:12:16 +0200 From: peter van der Stok To: Zach Shelby Organization: vanderstok consultancy Mail-Reply-To: In-Reply-To: <5F948749-91FB-4687-B0F6-CD0B713E3931@sensinode.com> References: <30a64b4fc85a612b82a5ed4fe685476e@xs4all.nl> <5F948749-91FB-4687-B0F6-CD0B713E3931@sensinode.com> Message-ID: <7e66b0ef133d031d61a4cd103108bb0f@xs4all.nl> X-Sender: stokcons@xs4all.nl (8OCbOQcjBJhPp0ros5/ESVBW29iKf5rq) User-Agent: XS4ALL Webmail X-Virus-Scanned: by XS4ALL Virus Scanner Cc: Core Subject: Re: [core] resource-directory-4 X-BeenThere: core@ietf.org X-Mailman-Version: 2.1.12 Precedence: list Reply-To: consultancy@vanderstok.org List-Id: "Constrained RESTful Environments \(CoRE\) Working Group list" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 24 Sep 2012 08:12:49 -0000 Hi Zach, In relation to the point below, Some questions remain. > >> In sec 5.3 the con parameter is also mentioned to update the entry. >> In the case that the host:port changes completely, a new entry is >> required IMO.

Following your reasoning when using host:port, then by reassigning changing IP addresses continuously to the RD end-points, the RD takes over DNS functionality? Would it not be better to keep DNS functionality outside the RD, use FQDNs, and only use IP addresses when the environment does not support DNS. In the latter case I do not see the IP addresses changing very frequently, because there is no IP provider either.

charset=us-ascii Hi, I have been working on integrating the Option re-numbering into coap-12, = and have done an analysis based on the original proposal from Carsten = presented in Vancouver. That proposal was already pretty good, but some = adjustments were made to optimize for the most commonly used option = combinations. Based on that optimization I am proposing the following = numbering. This takes into account Critical, Unsafe and Cache-key = encoding. This re-numbering requires the use of Jump only in a couple = response combinations where there is no payload and when doing Proxy-Uri = requests. In those situations overhead is not an issue as there is no = payload in the message, so the extra byte from including a Jump is = reasonable. Attached is the spreadsheet that was used to calculate the option = numbers, and check that the option combinations were optimal (avoiding = Jump where possible).=20 Note that also Observe and Block options are affected by the renumbering = (and thus updated drafts will be submitted in conjunction with the = coap-12 submission).

I will add a ticket for us to remember to make this registration. As we have already been through WGLC, this would be a good time to start the process. Would either one of you be willing to fill out the registration form? The spec authors are pretty busy right now getting the coap-12 release done.

Any suggestion?

Hi,

After Klaus’s suggestions I have updated the priority delivery mod= el. This version does not define any mechanism to allow clients to observe = only the states they wish to receive. Conditional observe or the use of par= ameterized resources could be used instead.

The new model defines three levels of delivery priority. A client uses t= he two most significant bits of the observe option value to require the des= idered priority level (Priority field). This is only present in the request= s sent by clients to observe a resource and in the consequent response of t= he server. The definition of the three levels and the relative Priority fie= ld values is the following:

-          High: the value = of the Priority field is 10.

-          Medium: the valu= e of the Priority field is 01.

-          Low: the value o= f the Priority field is 00.

Should a server receives multiples request for the same level of priorit= y, it orders them following the arrival order.

I’ve done the delay tests all over again. The delay has been calcu= lated as the time elapsed from the moment the server sends the first update= on the resource’s state until a client receives it. The update have = been sent using NON messages. Energy consumption and delivery ratio have no= t being evaluated since they are metrics that are not influenced by priorit= y delivery.

The tests are done in a star-topology WSN using TelosB motes. I consider= ed six different situations where each of them has a different number of cl= ients observing the same resource (from two to six). The application requir= ements are those of an e-health network used for monitoring the cardiac rat= e of a patient. The server sends updates each 200 ms when the patient is in= a critical state. The payload has a length of 2 bytes and contains the hea= rth rate obtained averaging the two last measures.

 Results are reported in the file attached to this e-mail.

Hello all,

 

I have uploaded the following document:

http://datatracker.ietf.org/doc/draft-greevenbosch-c= ore-minimum-request-interval/

 

The document replaces draft-greevenbosch-core-block-= minimum-time, but since the mechanism is now defined for a broader usage th= an just block transactions (e.g. the client browses the server), I thought = a rename was appropriate.

 

The draft describes a mechanism in which server and = client communicate about the request frequency the client is using (or rath= er, its reciprocal being the request interval). In this way, the server has= explicit means to slow down or speed up the client when appropriate.

 

The draft now allows to update the timing during the= transaction, whereas draft-...-block-minimum-time fixed the speed at the b= eginning of the transaction.

 

Comments are welcome!

 

Best regards,

Bert

Dear all,

 

A question about CoRE link format (RFC 6690). If a c= lient does a GET on /.well-known/core, the server can return resources host= ed in a fairly short description, e.g.:

</rd>;rt=3D"core.rd"

(18 bytes)

 

But this only works if the ‘rd’ resource= is hosted on default port 5683. If the resource is hosted at another port = (e.g. in the 6LoWPAN compressed port range), the returned link format seems= to become much longer e.g.:

<coap://[2001:ddb8:1234:ffff:ffff:ffff:ffff:ffff]:61616/rd>;rt= =3D"core.rd"

(72 bytes) including mostly unused information ̵= 1; the port here is the only new thing that matters!

 

There is however a shorter representation possible:<= /p>

<coap://:61616/rd>;rt=3D"core.rd"

(31 bytes) From RFC 3986, the “reg-name”= expression which may constitute the hostname (“host”), can be = empty. So this is valid syntax as long as the scheme/protocol (CoAP) spec a= llows this to be empty. For HTTP however it seems invalid, at least webbrowsers don’t support it.

 

Questions: does CoAP allow URIs with empty hostname?= Should it? If CoAP allows it, would it automatically be allowed in CoRE li= nk format RFC 6690 ?

 

Even shorter would be:

<:61616/rd>;rt=3D"core.rd"

(24 bytes) By leaving away the scheme it is indicate= d that it’s accessed with the same scheme that was used to fetch this= link-format. But an invalid URI.

Definitely worth looking at. So, looking at: > ;rt=3D"core.rd" (Note that would be equivalent in a document that was = obtained from a coap:// URI.) Unfortunately, that is an absolute URI, but would need to be interpreted = as a relative reference (RFC 3986 =A7 4.2). I.e., in the algorithm listed in =A7 5.2.2, this evaluates to true: defined(R.authority) (Or, in still other words, you get to take the entire authority from the = base or from the URI reference, but can't mix within.) Brainstorming mode: Note that we have not defined the name resolution mechanism to be used = for hostnames in CoAP URIs. We could define a special host notation as the "context host" (some = handwaving required here). Say, if that special notation we choose is ".": (We could also use an empty hostname, as you suggest above and as one = could read out of =A7 6.2.3, but that also contradicts other parts of = that subsection.) I'm not sure I like that approach, because it means existing relative = URI reference resolution implementations will need to add a special = case. (At least, this could be handled in a post-processing step after doing = the main resolution.)

It potentially negates the ability to reach all servers with a single multicast, essentially placing a well-known resource at a dynamic (and therefore non-deterministic) port. RFC6282 gives this guidance: The overloading of the 0xf0bX ports increases the risk of getting the wrong type of payload and misinterpreting the content compared to ports that reserved at IANA. It is thus recommended that the use of those ports be associated with a mechanism such as a Transport Layer Security (TLS) [RFC5246] Message Integrity Check (MIC) that validates that the content is expected and checked for integrity. Clearly DTLS is also incompatible with multicast resource discovery. Regards, -K- On Wed, Sep 26, 2012 at 3:52 AM, Dijk, Esko wrote: > Dear all, > > > > A question about CoRE link format (RFC 6690).

However the actual resources could be hosted at another endpoint on that se= rver, e.g. port 61616. Perhaps serving an 'rd' resource at a non-standard port is a confusing exam= ple; it could be replaced by e.g. ;rt=3D"ipso.sen" and the same issue still holds.

Perhaps a port redirect option in the response would even be more elegant and might work with the lookup interface.

I'm worried about slowly extending the life time of the cache by each step not taking into account the network latency. So if there is 2 condos of latency on the mesh network and device A passed something with a Max-Life to 10 seances to Cache B that later caches to cache B, it could end up living for multiple seconds longer than it should have. Also, Klaus Hartke notes (nits9c): Retransmission of a response can significantly extend the time the response takes to arrive at the client. Should the Max-Age of the response be reduced with each retransmission? (See also [msg03072ai]) The somewhat lame text that has been added to the working version of coap-12 is: Considering potential network delays on the way from the origin server, a proxy SHOULD be conservative in the max-age values offered. However, we could also add text that recommends (or requires?) proxies to update max-age in their retransmissions. We could also extend this recommendation/requirement to origin servers. Carsten's view: In many cases, this is a quality of implementation issue. But it does not hurt to point out the issue. So I added text in the definition of the option Max-Age that indicates that the value of Max-Age is current at the time of transmission. -- -----------------------------+------------------------------------ Reporter: cabo@… | Owner: draft-ietf-core-coap@… Type: other technical | Status: new Priority: minor | Milestone: post-WGLC-1 Component: coap | Version: coap-09 Severity: In WG Last Call | Keywords: -----------------------------+------------------------------------ Ticket URL: core From trac+core@trac.tools.ietf.org Fri Sep 28 16:22:34 2012 Return-Path: X-Original-To: core@ietfa.amsl.com Delivered-To: core@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id B063521F8549 for ; Fri, 28 Sep 2012 16:22:34 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -102.599 X-Spam-Level: X-Spam-Status: No, score=-102.599 tagged_above=-999 required=5 tests=[AWL=0.000, BAYES_00=-2.599, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([64.170.98.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id ZDGLpNZOip2j for ; Fri, 28 Sep 2012 16:22:34 -0700 (PDT) Received: from grenache.tools.ietf.org (grenache.tools.ietf.org [77.72.230.30]) by ietfa.amsl.com (Postfix) with ESMTP id 20DCA21F84FF for ; Fri, 28 Sep 2012 16:22:34 -0700 (PDT) Received: from localhost ([127.0.0.1]:38378 helo=grenache.tools.ietf.org ident=www-data) by grenache.tools.ietf.org with esmtp (Exim 4.77) (envelope-from ) id 1THjsy-00046M-TO; Sat, 29 Sep 2012 01:22:20 +0200 MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 8bit From: "core issue tracker" X-Trac-Version: 0.12.2 Precedence: bulk Auto-Submitted: auto-generated X-Mailer: Trac 0.12.2, by Edgewall Software To: hartke@tzi.org, zach@sensinode.com, cabo@tzi.org X-Trac-Project: core Date: Fri, 28 Sep 2012 23:22:20 -0000 X-URL: http://tools.ietf.org/core/ X-Trac-Ticket-URL: http://trac.tools.ietf.org/wg/core/trac/ticket/226#comment:2 Message-ID: <066.f8eefdc95257dcc06824a47c8d77e9cd@trac.tools.ietf.org> References: <051.6d1a8fefd2f87314224527d7678c8be2@trac.tools.ietf.org> X-Trac-Ticket-ID: 226 In-Reply-To: <051.6d1a8fefd2f87314224527d7678c8be2@trac.tools.ietf.org> X-SA-Exim-Connect-IP: 127.0.0.1 X-SA-Exim-Rcpt-To: hartke@tzi.org, zach@sensinode.com, cabo@tzi.org, core@ietf.org X-SA-Exim-Mail-From: trac+core@trac.tools.ietf.org X-SA-Exim-Scanned: No (on grenache.tools.ietf.org); SAEximRunCond expanded to false Cc: core@ietf.org Subject: Re: [core] #226: Clarify which language addresses intermediaries in general vs. forward proxies specifically X-BeenThere: core@ietf.org X-Mailman-Version: 2.1.12 Reply-To: trac+core@trac.tools.ietf.org List-Id: "Constrained RESTful Environments \(CoRE\) Working Group list" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 28 Sep 2012 23:22:34 -0000 #226: Clarify which language addresses intermediaries in general vs. forward proxies specifically Changes (by cabo@…): * status: new => closed * resolution: => fixed Comment: (This was already declared fixed on Sep 26, but then Trac bumped into a lamppost.)

When used with block, should each block be compressed individually or transfers each block a part of the compressed representation? If the former, which flush mode should be used, Z_SYNC_FLUSH, Z_PARTIAL_FLUSH or Z_FULL_FLUSH? Carsten's point of view: The intention is to transfer the content-coded representation, which is sliced up in blocks. The sender (side that does the slicing) may want to do the compression incrementally, however, it has to make sure the slices are an exact power of two number of bytes. This makes flushing precisely at the block boundaries hard. (The sender may still want to do flushing, but this is an implementation decision.) The recipient obtains a content-coded representation that can be decompressed incrementally, but where the block boundaries do not mean anything and therefore don't need to be reproduced by flushing. This item would benefit from input from implementers that use content- coding with CoAP. -- -----------------------------+------------------------------------- Reporter: cabo@… | Owner: draft-ietf-core-block@… Type: other technical | Status: new Priority: minor | Milestone: post-WGLC-1 Component: block | Version: block-08 Severity: In WG Last Call | Keywords: -----------------------------+------------------------------------- Ticket URL: core From trac+core@trac.tools.ietf.org Sun Sep 30 07:43:46 2012 Return-Path: X-Original-To: core@ietfa.amsl.com Delivered-To: core@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 8D69721F8669 for ; Sun, 30 Sep 2012 07:43:46 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -102.599 X-Spam-Level: X-Spam-Status: No, score=-102.599 tagged_above=-999 required=5 tests=[AWL=0.000, BAYES_00=-2.599, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([64.170.98.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id QzjehQ1uqjpo for ; Sun, 30 Sep 2012 07:43:46 -0700 (PDT) Received: from grenache.tools.ietf.org (grenache.tools.ietf.org [77.72.230.30]) by ietfa.amsl.com (Postfix) with ESMTP id C38A421F85E6 for ; Sun, 30 Sep 2012 07:43:45 -0700 (PDT) Received: from localhost ([127.0.0.1]:51399 helo=grenache.tools.ietf.org ident=www-data) by grenache.tools.ietf.org with esmtp (Exim 4.77) (envelope-from ) id 1TIKjz-0002Ec-9u; Sun, 30 Sep 2012 16:43:31 +0200 MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 8bit From: "core issue tracker" X-Trac-Version: 0.12.2 Precedence: bulk Auto-Submitted: auto-generated X-Mailer: Trac 0.12.2, by Edgewall Software To: draft-ietf-core-coap@tools.ietf.org, cabo@tzi.org X-Trac-Project: core Date: Sun, 30 Sep 2012 14:43:31 -0000 X-URL: http://tools.ietf.org/core/ X-Trac-Ticket-URL: http://trac.tools.ietf.org/wg/core/trac/ticket/246 Message-ID: <051.c0be34405f3e5e5cab4565e76bf12039@trac.tools.ietf.org> X-Trac-Ticket-ID: 246 X-SA-Exim-Connect-IP: 127.0.0.1 X-SA-Exim-Rcpt-To: draft-ietf-core-coap@tools.ietf.org, cabo@tzi.org, core@ietf.org X-SA-Exim-Mail-From: trac+core@trac.tools.ietf.org X-SA-Exim-Scanned: No (on grenache.tools.ietf.org); SAEximRunCond expanded to false Resent-To: brian@skyfoundry.com, cabo@tzi.org, hartke@tzi.org, zach@sensinode.com Resent-Message-Id: <20120930144345.C38A421F85E6@ietfa.amsl.com> Resent-Date: Sun, 30 Sep 2012 07:43:45 -0700 (PDT) Resent-From: trac+core@trac.tools.ietf.org Cc: core@ietf.org Subject: [core] #246: Estimation of Leisure X-BeenThere: core@ietf.org X-Mailman-Version: 2.1.12 Reply-To: trac+core@trac.tools.ietf.org List-Id: "Constrained RESTful Environments \(CoRE\) Working Group list" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 30 Sep 2012 14:43:47 -0000 #246: Estimation of Leisure Cullen Jennings notes (msg03072q): Section 4.5 Estimation Leisure. I do not see how someone implementing a COAP stack can figure out S, G, and R. I think we should define a configurable parameter called LEISURE_TIME and set it to 5 seconds. To be clear, I don't think the current algorithm is implementable. ➔ coap-12 [941] contains a new constant DEFAULT_LEISURE that can be used by implementations that can't figure it out. -- -----------------------------+------------------------------------ Reporter: cabo@… | Owner: draft-ietf-core-coap@… Type: other technical | Status: new Priority: minor | Milestone: post-WGLC-1 Component: coap | Version: coap-09 Severity: In WG Last Call | Keywords: -----------------------------+------------------------------------ Ticket URL: core
