[Rachel]: Yes, you're right. Will do it.

Point

[Rachel]: it's "point". I'll use "one" instead of "some" to avoid ambiguity=
. What do you think?

[Rachel]: Marking "PEER REGISTRERED" state with "Transient" is because we d=
on't have to wait for any messages in this state. When a tracker receives t=
he CONNECT message from a new peer, it will move the peer's state from STAR=
T to PEER REGISTERED. After analyzing and authenticating the CONNECT messag=
e, the tracker moves the states to either "TRACKING" or "TERMINATE". So thi=
s state is quite short, depending on the time that the tracker deals with t=
he new CONNECT message.

Hi,

I reviewed the document and have some comments and nits. 

 

 

1.       Nit: In section 1 "The PPSP architecture requires PPSP peers able
to communicate" should be "The PPSP architecture requires that PPSP peers
are able to communicate"

2.       In section 1.1 "CHUNK ID" is it identifier for SEGMENT CHUNK or for
a CHUNK. Also you need to expand MPD.  I also have a question if the address
scheme is described in the MPD?

3.       In section 1.1 "TRACKER" it says that it also answers PEER LIST
queries. It does not mention the other requests, is this the only one that
it respond to?

4.       In 2.1 3rd paragraph you mention the service Portal, it is not
mentioned in section 1.1 but the connection tracker is.

5.       In section 2.3 delete "over it" at the end of the section.

6.       A general question on transport (relates also for 2.3, 2.3.1,. ),
do you mandate using TLS for security reasons, or is also TCP allowed and
when? In section 7.1 second paragraph says that a channel oriented security
mechanism should (change to SHOULD) be used. Why SHOULD and not MUST in
which cases you can use non secure communication between peers and tracker?

7.       In section 2.3.2 "FIND" - "This Request message is an "action
signal" used by peers to request to the tracker"  change "to request from
the tracker"

8.       In section 4 for  why is PPSP_TP_EXTENDED have the comment before
"//"  typedef enum ppsp_tp_versions {

                   PPSP_TP_BASE       = 0x10, // or "1.0"
                // PPSP_TP_EXTENDED   = 0x11, // or "1.1"
      } ppsp_tp_version_t;
 
9.       In the ppsp_tp_peer_addr there is an enum for connection, how is it
used, is it for information only in which case why is it in each message?
10.   In section 6.1.3 the security is in 7.1 and not 6.1 
 
Thanks
Roni Even

Hi Roni,

I can answer some of the questions. Please see inline. Authors, please corr=
ect me if I'm wrong.
BTW, just let you know that we also have an extended tracker protocol draft=
. If you're interested in it, please read it and give some comments.
Thanks.

BR,
Rachel

Subject: [ppsp] review of base tracker protocol

Hi,
I reviewed the document and have some comments and nits.



1.       Nit: In section 1 "The PPSP architecture requires PPSP peers able =
to communicate" should be "The PPSP architecture requires that PPSP peers  =
are able to communicate"
[Rachel]: Okay.


2.       In section 1.1 "CHUNK ID" is it identifier for SEGMENT CHUNK or fo=
r a CHUNK. Also you need to expand MPD.  I also have a question if the addr=
ess scheme is described in the MPD?
[Rachel]:  I think it is for a CHUNK. And I don't think we have to bring th=
e term "SEGMENT CHUNK" to tracker protocol. And yes, chunk addressing schem=
e could be described in MPD. Actually, section 1.1 has defined MEDIA PRESEN=
TATION DESCRIPTION (MPD).


3.       In section 1.1 "TRACKER" it says that it also answers PEER LIST qu=
eries. It does not mention the other requests, is this the only one that it=
 respond to?
[Rachel]: I agree it's not accurate.  Need fix. Maybe just delete "PEER LIS=
T".


4.       In 2.1 3rd paragraph you mention the service Portal, it is not men=
tioned in section 1.1 but the connection tracker is.

5.       In section 2.3 delete "over it" at the end of the section.
[Rachel]: Okay.


6.       A general question on transport (relates also for 2.3, 2.3.1,... )=
,  do you mandate using TLS for security reasons, or is also TCP allowed an=
d when? In section 7.1 second paragraph says that a channel oriented securi=
ty mechanism should (change to SHOULD) be used. Why SHOULD and not MUST in =
which cases you can use non secure communication between peers and tracker?

7.       In section 2.3.2 "FIND" - "This Request message is an "action sign=
al" used by peers to request to the tracker"  change "to request from the t=
racker"
[Rachel]: Okay.


8.       In section 4 for  why is PPSP_TP_EXTENDED have the comment before =
"//"  typedef enum ppsp_tp_versions {

                   PPSP_TP_BASE       =3D 0x10, // or "1.0"

                // PPSP_TP_EXTENDED   =3D 0x11, // or "1.1"

      } ppsp_tp_version_t;
[Rachel]: Need fix. It should be extended in extended tracker protocol draf=
t.



9.       In the ppsp_tp_peer_addr there is an enum for connection, how is i=
t used, is it for information only in which case why is it in each message?

[Rachel]: It's just information for this specific interface. Peer will tell=
 tracker its interface connection information, and the peer list sent from =
tracker also includes this information for each peer address.



10.   In section 6.1.3 the security is in 7.1 and not 6.1
[Rachel]: Okay.





Thanks

Roni Even

Subject: [ppsp] Reivew of the base tracker protocol


Hi,

   (Speaking individually) I have reviewed the latest three versions of the=
 base tracker protocol and have the following comments. Wish it helpful for=
 today's online discussion.



General: I do like the idea in the latest two versions that the new section=
 (section 3 and the corresponding update in section 4) has been added to ad=
dress to accomodate different encodings in unified data type.



Comments:

1) Section 4.1:

typedef struct {

                     CONCRETE_PROTO_SPEC_DEPENDENT    address;

                     // string, addr_in4,

                     // addr_in6, addr_storage

                     CONCRETE_PROTO_SPEC_DEPENDENT    port;

                     // string (IANA service port),

                     // or uint16 (service port)

Is the definition of the type of address and port missing? I didn't find th=
em before.

 [Rachel]: Yes. Comparing to previous xml format, the address type is missi=
ng.

2) In the end of section 5.1 and 5.2, there is an IMPLEMENTATION NOTE sayin=
g: If no PeerNum attributes are present in the request the tracker MAY retu=
rn a random sample from the peer population.

It's suggested to set a DEFAULT value for the return number if no explict r=
equest of number.

 [Rachel]: Agree. The tracker should set a DEFAULT value. And I think this =
should also apply in the case of peer_count=3D 0.

Subject: [ppsp] Notes from the online discussion


Hi all,

    The following is the quick notes from the online discussion.



Attendees: Yunfei, Rachel, Mi, Jianwei,Dave,K?

Base tracker protocol:

1. Yunfei: See comments from Roni (Thanks Roni) and also sent comments to t=
he mailing list. Rachel reeplied in the mailing list.

2. Dave: Efficiency comparison bw text based and binary protocol.

    Rachel and Yunfei recalled the history of this problem and the current =
WG consensus is to let the encoding issue out of scope of the current proto=
col development and focus on syntax and sementics.

3. Yunfei calls for more volunteered experts to review the base tracker pro=
tocol so that the WG can stablize and finalize the draft.



Extended tracker protocol:

1.  Yunfei: The chunk addressing issue. The draft states that one swarm sup=
port one kind of chunk addressing. So who decides the chunk addressing sche=
me? The first peer or the content provider? It should be explict.

Rachel: Content provider.

   Yunfei: Suggest to ask for Arno to clarify if it is easy to convert from=
 one kind of chunk addressing scheme to another( has the impression that it=
 is easy in the peer protocol draft). If it were the case, it will provide =
the content owner a good feather to easily attract more peers who will othe=
rwise supports only one kind of chunk addressing scheme in the software.

 [Rachel]: I have discussed with Arno before. See http://www.ietf.org/mail-=
archive/web/ppsp/current/msg01753.html. I don't think converting from one k=
ind to another should be considered.

BR

Yunfei

Hi, folks,

Hi all

when I look at the binary encoding in Section 3 the following questions
come up:
1. Why wasn't an existing encoding standard chosen?
2. The draft does not specify the endianness for the integer data?
3. Is there a need to support Unicode/internationalization? If so, this
should be added.

CU,
    Arno

I presume when PPSPP was still called Swift, SHA1 was not yet considered =
weak. Times have changed, see =5B1=5D,=5B2=5D, and speed of e.g. SHA256 i=
s comparable for our requirements =5B3=5D,=5B4=5D. BTW This has been rais=
ed already in area review briefly.

The significance of hash weaknesses for a transport protocol are severe -=
 ability for a malicious (*cough* NSA, RIAA *cough*) entity to inject dat=
a that ultimately prevents the end user from unzipping or decrypting the =
transffered content or archive due to corruption by re-using a hash, is a=
 serious weakness.

Given that SHA1 has been considered weak since 2005 (yes, 2005, that=E2=80=
=99s almost a DECADE ago), are there any reasons for not removing SHA1 en=
tirely from the PPSPP Spec while we still have the chance=3F

It may seem obvious, but shouldn=E2=80=99t we have an update on the core =
protocol=E2=80=99s status=3F

I=E2=80=99d like to propose we remove sha1 support entirely; I will send =
a separate email to discuss that.

Abstract:
   This document presents a survey of some of the most popular Peer-to-
   Peer (P2P) streaming applications on the Internet.  The main
   selection criteria have been popularity and availability of
   information on operation details at writing time.  In doing this,
   selected applications are not reviewed as a whole, but they are
   reviewed with main focus on the signaling and control protocol used
   to establish and maintain overlay connections among peers and to
   advertise and download streaming content.

Abstract:
   This document specifies the base Peer-to-Peer Streaming Protocol-
   Tracker Protocol (PPSP-TP/1.0), an application-layer control
   (signaling) protocol for the exchange of meta information between
   trackers and peers.  The specification outlines the architecture of
   the protocol and its functionality, and describes message flows,
   message processing instructions, message formats, formal syntax and
   semantics.  The PPSP Tracker Protocol enables cooperating peers to
   form content streaming overlay networks to support near real-time
   Structured Media content delivery (audio, video, associated timed
   text and metadata), such as adaptive multi-rate, layered (scalable)
   and multi-view (3D) videos, in live, time-shifted and on-demand
   modes.

Abstract:
   The Peer-to-Peer Streaming Peer Protocol (PPSPP) is a protocol for
   disseminating the same content to a group of interested parties in a
   streaming fashion.  PPSPP supports streaming of both pre-recorded
   (on-demand) and live audio/video content.  It is based on the peer-
   to-peer paradigm, where clients consuming the content are put on
   equal footing with the servers initially providing the content, to
   create a system where everyone can potentially provide upload
   bandwidth.  It has been designed to provide short time-till-playback
   for the end user, and to prevent disruption of the streams by
   malicious peers.  PPSPP has also been designed to be flexible and
   extensible.  It can use different mechanisms to optimize peer
   uploading, prevent freeriding, and work with different peer discovery
   schemes (centralized trackers or Distributed Hash Tables).  It
   supports multiple methods for content integrity protection and chunk
   addressing.  Designed as a generic protocol that can run on top of
   various transport protocols, it currently runs on top of UDP using
   LEDBAT for congestion control.

Hi

I did not follow the whole discussion, but the draft should be such that
interoperable implementations can be made. Weren't the encodings
supposed to go into appendices?

CU,
