Hi, Mi,

 = ;

I noticed = that in Section 4, you listed the parameters adopted by Tracker Protocol &a= mp; Peer Protocol. It=A1=AFs ideal that you could further give some benchmarking data as the results of your PPSP system. For example, you cou= ld run a P2P live streaming test and report the results under your settings= .

Thanks.

This draft is a work item of the Peer to Peer Streaming Protocol Working Group of the IETF. Title : Peer-to-Peer Streaming Peer Protocol (PPSPP) Authors : Arno Bakker Riccardo Petrocco Victor Grishchenko Filename : draft-ietf-ppsp-peer-protocol-12.txt Pages : 111 Date : 2014-11-28 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 reviewed the draft and in gen= eral it looks OK, some comments

 

1. &nbs= p;     In section 5.3 in the f= irst case it says that the peer will now if the tracker supports the extens= ion based on the error response why cannot the peer know it based on the pp= sp_tp_versions value

[Rachel]: Because there=A1=AFs no negotiation in the whole tracke= r protocol design. So the first message sent from the peer is the CONNECT m= essage. Only when the tracker responds,  the peer know if the tracker supports the extension.

 

2.       In section 5.4 why not = say that if a tracker support version 01 it MUST support the same chunk add= ressing method as the peers. This will be in line with section 4 of peer pr= otocol that says =A1=B0All peers in a swarm MUST use the same chunk addressing metho= d.=A1=B0

 

[Rachel]: But a tracker could serve = multiple swarms. What if different swarms chooses different chunk addressin= g methods? Actually the principle in the extended tracker protocol is consistent with the peer protocol. See sectio= n 5.4 : =A1=B0Multiple chunk addressing methods could be us= ed in this document to present content information. But only one of them MUST be used for

one swarm when a peer communicating with a tracker.=A1=B1

 

Thanks

This draft is a work item of the Peer to Peer Streaming Protocol Working Group of the IETF. Title : PPSP Tracker Protocol-Base Protocol (PPSP-TP/1.0) Authors : Rui Santos Cruz Mario Serafim Nunes Gu Yingjie Jinwei Xia Rachel Huang Joao P. Taveira Deng Lingli Filename : draft-ietf-ppsp-base-tracker-protocol-07.txt Pages : 56 Date : 2014-12-11 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. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-ppsp-base-tracker-protocol/ There's also a htmlized version available at: http://tools.ietf.org/html/draft-ietf-ppsp-base-tracker-protocol-07 A diff from the previous version is available at: http://www.ietf.org/rfcdiff?url2=draft-ietf-ppsp-base-tracker-protocol-07 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

Section 3.1, point 1, "In the same swarm, peers MUST use the same = chunk addressing method and the same encoding type to ensure that peers can= communicate with each other smoothly". In the newest version, tracker prot= ocol uses text encoding and peer protocol uses binary encoding. So there's = no need to mention the same encoding type here. 2. Section 3.2, paragraph 10, "For that purpose, the Peer B needs to = connect and login a service Portal with peer ID and transaction ID to get t= he MPD file of the selected swarm x". Transaction ID is not obtained from t= he portal. It's from the tracker. 3. Section 3.2, paragraph 14. I think sending PER_REQ message to get = other peers' information is optional, right? 4. Section 3.2 "Meanwhile, Peer B SHOULD use FIND or CONNECT message = to log out and eliminate its state machine in tracker". FIND message cannot= let a peer to log out from a swarm or tracker. FIND message is only used t= o update the peer list. Use "STAT_REPORT" message instead. 5. Section 3.2, "Peer B MAY use FIND or CONNECT message to join a new= swarm, such as swarm y or z in Figure 1". FIND message cannot let a peer t= o join a new swarm. 6. Section 4.1, If these values are reasonable, they should be incorp= orated into the tracker protocol. 7. Section 5, issue 1, tracker protocol has an attribute in PeerGroup= to indicate by what kind of access the peer is connecting. It's kind of ex= tending the P2P system in mobile and wireless environments. Of course we ca= n extend the tracker protocol to include the packet loss rate and battery s= tatus. However, I'm not sure about it because these two parameters are not = general enough, especially battery status. 8. Section 5, issue 2, I think it depends on the implementations. For= applications that will be supervised by ISPs, tracker protocol and peer pr= otocol without searching peers should be used. 9. Section 5, issue 3, I don't understand why the tracker could only = use PeerMode to choose the PeerList? For tracker protocol, I think both Lee= ch and Seed can be included in the Peerlist. 10. Section 5, issue 4. This is addressed in the extended tracker protoco= l. 11. Section 5, issue 5. What's the intention? 12. Section 5, issue 6. Message exchanging frequency is not issue for bas= e tracker protocol, because there's only a little signaling data delivered = by tracker protocol. The most frequent message is STAT_REPORT message which= may be 1 minute interval if setting Track_timeout to 3 minutes.

In = the newest version, tracker protocol uses text encoding and peer protocol uses binary encoding. So there’s no need to mention the sam= e encoding type here.

5.       Se= ction 3.2, “Peer = B MAY use FIND or CONNECT message to join a new swarm, such as swarm y or z in Figure 1”= . FIND message cannot let a peer to join a new swarm.

6.       Se= ction 4.1, If these values are reasonable, they should be incorporated into= the tracker protocol.

7.       Se= ction 5, issue 1, tracker protocol has an attribute in PeerGroup to indicat= e by what kind of access the peer is connecting.

7.    &n= bsp; Section 5, issue 1, tracker pr= otocol has an attribute in PeerGroup to indicate by what kind of access the= peer is connecting. It=A1=AFs kind of extending the P2P system in mobile and wireless environments. Of course we can extend the tracker p= rotocol to include the packet loss rate and battery status. However, I=A1= =AFm not sure about it because these two parameters are not general enough,= especially battery status.

I think usage in mobile environment should consider handover= between base stations and switch between WIFI & Telecom Operator. Also, as data transmissi= on uses power (and the power especially used in upload is sometimes conside= red as wasted by selfish users), I think we should consider that.

[Rachel]: Maybe we could put these parameters in as= optional ones. It that okay for everyone?

8.    &n= bsp; Section 5, issue 2, I think it= depends on the implementations. For applications that will be supervised b= y ISPs, tracker protocol and peer protocol without searching peers should be used.

It makes sense. Different application scenarios co= uld set the specific coordinated method of updating PeerList.

But we think if PPSP provides some efficiently way= , it will be better for implementers and users.

[Rachel]: What kind of efficient= way are you suggesting? IMHO, the protocols in PPSP already have the flexibility to deal with different application scenarios.<= span lang=3D"EN-US" style=3D"font-family:"Times New Roman","= serif"">

9.    &n= bsp; Section 5, issue 4. This is ad= dressed in the extended tracker protocol.

Yes, we write our protocol based on the two active Internet-= Drafts, they haven=A1=AFt mentioned it.

We agree with your point in extend tracker protocol. But our= current Usage of PPSP is based on the base-tracker protocol and peer protocol, so we take this gap out.

10.  Section 5, issue 5. What=A1=AF= s the intention?

First, by splitting a large swarm, we can shorten the time u= sed in searching & connecting. Second, users under different ISPs (Internet Service Provider) m= ight face higher delay when connect with each other. So I think it would be= better if we could adjust size of swarm according to QoS.

[Rachel]: I think it=A1=AFs an implementation issue= rather than a protocol issue.

11.   Section 5, issue 6. Mes= sage exchanging frequency is not issue for base tracker protocol, because t= here=A1=AFs only a little signaling data delivered by tracker protocol. The most frequent message is STAT_REPORT message which may be 1 minute interva= l if setting Track_timeout to 3 min= utes.

 

    &nb=
sp;          That=A1=AFs true.=
 But the point we are trying to give is thatwe should take bandwidth into c=
onsideration to adjust the video definition and other parameters.

[Rachel]: I= =A1=AFm not sure I understand your point. The sentence in RFC6972 says

=A1=B0The tracker (peer) protocol MUST take the frequency of message

      exchange and efficient band= width use into consideration when

      communicating chunk av= ailability information (chunk information).

=A1=B1 IMO,= the tracker protocol has already satisfied such requirement, just as I exp= lained before. But you are say =A1=B0the user may want to adjust the video

      definition based on the ban= dwidth (or user demand)

      automatically (or manu= ally).

=A1=B1I think this is not issue for tracker protocol, be= cause peers report their bandwidth to the tracker which is already been included in current tracker protocol, and it is possible for = a peer to leave a swarm firstly and then join another one (like you said ba= sed on user=A1=AFs demard). So what kind of other abilities do you want the= tracker protocol to have?

=D6=F7=CC=E2: [ppsp] ***SPAM*** 5.939 (5) review of base tracker protocol -07

 

Hi,

 

<= /a>I have reviewed the PPSP= -TP 07, it is very clear and neat. In general, I have no comments about the procedures, but there are some trivial problems:

 

1)        Section 2.3.2<= o:p>

 c) =A1=B0transitions= to TERMINATE state for that Peer ID and and the SM is destroyed.=A1=B1

 

Duplicated =A1=B0and=A1=B1.<= /span>

 = ;

JW: will c= orrect it.

 

2)        Section 6.12

Paragraph 5, =A1=B0To prov= ide more choices for the requesting peer, the tracker may select a new peer= list with lower priority from the list of peers and return it to the requesting peer later.=A1=B1

 

I am not sure =A1=B0later=A1=B1 refers to what time or condition specifically.

 = ;

JW: it dep= ends on the actual implementation, up to PPSP provider to decide it.

 

3)        Section 6.3

Paragraph 3, =A1=B0The tra= cker SHOULD be prepared to receive a Request with a repeated TransactionID.= =A1=B1

 

What kind of preparations SHOULD the tracker make?

 

JW: it nee= ds to judge what error happen and response an corresponding error code.

 = ;

4)        Section 7.1.2<= o:p>

Last sentence, =A1=B0this = specification does not details a m= igration path.=A1=B1

 

=A1=B0details=A1=B1 or =A1=B0de= tail=A1=B1 ?

 = ;

JW: will b= e =A1=B0detail=A1=B1.

 

5)        Section 8=

Paragraph 2, =A1=B0No secu= rity system can guarantees= complete security=A1=AD.=A1=B1

 

=A1=B0guarantees=A1=B1 or =A1=B0guarantee=A1=B1?

 

 JW: will be =A1=B0guarantee=A1=B1.<= /span>

 = ;

And here are some proposed changes to= the json text after a glance at the draft. 1. "struct" should be changed to object. For example, change: =20 struct {=20 s1 e1;=20 s2 e2; ... sn en; } type_name; to object { s1 e1;=20 s2 e2; ... sn en; } type_name; 2. Do not use "enum" type, and change to others instead, due to there's no = enum type in JSON language. 3. the version of "ppsp_tp_version_t" should be registered in IANA? 4. You might change: Object { ppsp_tp_stat_type_t type; union { Object { ppsp_tp_string_t swarm_id; ppsp_tp_integer_t uploaded_bytes; ppsp_tp_integer_t downloaded_bytes; ppsp_tp_integer_t available_bandwidth; } stream_stats; } stat_data; } ppsp_tp_stat_t; to: Object { ppsp_tp_string_t swarm_id; ppsp_tp_integer_t uploaded_bytes; ppsp_tp_integer_t downloaded_bytes; ppsp_tp_integer_t available_bandwidth; } stream_stats; Object { ppsp_tp_stat_type_t type; stream_stats str_stats_value; } stat_data; 5. suggest to change media type "application/ppsp+json" to "application/pps= ptracker+json" 6. The examples in Section 6 seems inconsistent with the data structures in= Section 4. They should be fixed.
