The peer protocol > also defines the requests and responses of the chunks among the > peers. The last part means the data exchange requests and respones, isn't it? > PPSP.PP.REQ-1: The streaming content availability request message > MUST allow the peer to solicit the chunk information from other peers > in the peer list. The chunk information MUST at least contain the > chunk ID. This chunk availability information MUST NOT be passed on > to other peer, unless validated (e.g. prevent hearsay and DoS). This seems to be a requirement which is made up of several requirements. First of all, a mechanism is required to exchange information about the avail. of chunks. Second this information must contain the chunk ID of available or unavailable chunks? Third, do not forward this information. Section 6.3., paragraph 2: > PPSP.PP.REQ-2: The streaming content availability reply message MUST > allow the peer to offer the information of the chunks in its content > buffer. The chunk information MUST at least contain the chunk ID. We do not define messages here. Only protocol requirements. This holds also true for the other requirements in this section. The chunk ID part is duplicated from REQ1. What is this requirement about?? Section 6.3., paragraph 3: > PPSP.PP.REQ-3: The streaming content availability request message > SHOULD allow the peer to solicit an additional list of peers to that > received from the tracker - with the same swarm ID. The reply > message MUST contain swarm-membership information of the peers that > have explicitly indicated they are part of the swarm, verifiable by > the receiver. This additional list of peers MUST only contain peers > which have been checked to be valid and online recently (e.g. prevent > hearsay and DoS). Too many requirements packed into a single one. Please sort them out into multiple requirements. Section 6.3., paragraph 5: > PPSP.PP.REQ-4: Streaming content availability update message among > the peers MUST be supported by the peer protocol. The peer protocol > MUST implement either pull-based, push-based or both. This seems to be related to REQ1? What is the difference? I assume that a general description of the peer protocol, e.g., used to contanct other peers, to exchange information about what chunks are available, etc will help in defining the requirements. Section 6.3., paragraph 7: > PPSP.PP.REQ-5: The chunk availability information between peers MUST > be expressed as compactly as possible. Please remove this requirements, as it is not clear in technical terms what 'compact' is referring to. There is no measure to say that one protocol is sending more or less data for the chunk availability we have agreed on. It might be good to retain this information in a descriptive text, but not as a requirement. Section 6.3., paragraph 9: > PPSP.PP.REQ-6: The peer status report/update SHOULD be advertised > among the peers in order to reflect the status of the peer. Peer > status information should be advertised among the peers via the > peer status report/update message. For example, peer status can be > online time, physical link status including DSL/WiFi/etc, battery > status, processing capability, and other capabilities of the peer. > With such information, a peer can select more appropriate peers for > streaming. This requirement should probably read like 'the peer protocol MUST support the exchange of additional information about the peers. This information canbe, for instance, information about the access link or information about whether a peer is running on battery or is connected to a power supply. Section 6.3., paragraph 10: > PPSP.PP.REQ-7: The peers MUST implement the peer protocol for chunk > data (not availability information) requests and responses among the > peers before the streaming content is transmitted. What is this requirement about? I do not understand the intent of this requirement. Section 7., paragraph 2: > - Originate denial of service (DOS) attacks to the trackers by > sending large amount of requests with the tracker protocol; > - Originate fake information on behalf of other peers; > - Originate fake information about chunk availability; I would add more a classification about where the attack can happen, e.e.g., on tracker info, the info between the peers, on the content. Section 7., paragraph 5: > PPSP.SEC.REQ-1: PPSP MUST support closed swarms, where the peers are > authenticated. A closed swarm does not need necessarily authentication, but also run in a wallend garden, i.e., in a private network. The requirement is ok, but I would remove the authenticated here and also add a further requirement adding the ability to authenticate peers. Further, this requirement w/o authenticatoin does not belong here, but somewhere else, e.g., what are requirements for the tracker and the peers out of this? Section 7., paragraph 7: > PPSP.SEC.REQ-2: Confidentiality of the streaming content in PPSP > SHOULD be supported and the corresponding key management scheme > SHOULD scale well in P2P streaming systems. Again, these are requirements. And, how do you define scale well? Section 7., paragraph 8: > PPSP.SEC.REQ-3: PPSP MUST provide an option in order to encrypt the > data exchange among the PPSP entities. What is 'an option' in this case? You mean more the 'ability' isn't it?An option is reading more like a protocol option. Section 7., paragraph 9: > PPSP.SEC.REQ-4: PPSP MUST have mechanisms in order to limit potential > damage caused by malfunctioning and badly behaving peers in the P2P > streaming system. It will very hard, up to impossible, to proof this requirement. Section 7., paragraph 10: > Such an attack will degrade the quality of the rendered media at the > receiver. For example, in a P2P live streaming system a polluter can > introduce corrupted chunks. Each receiver integrates into its > playback stream the polluted chunks it receives from its neighbors. > Since the peers forwards chunks to other peers, the polluted content > can potentially spread through the P2P streaming network. Please specifiy a protocol requirement to mitigate this type of attack. Section 7., paragraph 11: > PPSP.SEC.REQ-5: PPSP SHOULD support identifying badly behaving peers, > and exclude or reject them from the P2P streaming system. What does this mean? Logging, for instance, or list with bad peers? Section 7., paragraph 12: > PPSP.SEC.REQ-6: PPSP MUST prevent peers from DoS attacks which will > exhaust the available resources of the P2P streaming system. I have trouble to see how this can be implemented in a protocol? If a per wants to start a DoS attack, it can do it. However, the peer protocol and the tracker protocols shouldn't make life easy for such peers. Section 7., paragraph 14: > PPSP.SEC.REQ-7: PPSP SHOULD be robust, i.e., when centralized tracker > fails, the P2P streaming system SHOULD still work by supporting > distributed trackers. This is not a security requirement, but it is a requirement for the protocol design. Section 7., paragraph 15: > PPSP.SEC.REQ-8: Existing P2P security mechanisms SHOULD be re-used as > much as possible in PPSP, to avoid developing new security mechanisms. Not a protocol requirement, but more a design guideline. Section 7., paragraph 16: > PPSP.SEC.REQ-9: Integrity of the streaming content in PPSP MUST be > supported to provide a peer with the possibility to identify > unauthentic media content (undesirable modified by other entities > rather than its genuine source). The corresponding checksum > distribution and verification scheme SHOULD scale well in P2P > streaming system and be robust against distrustful trackers/peers. The descriptive text out of REQ-4 fits perfectly and it is one attack vector. Remove REQ-4 keep REQ-9 and add extra requirements that state what the other protocol requirements are to get rid off other bad peers. Section 7., paragraph 17: > The PPSP protocol specifications will document the expected threats > (and how they will be mitigated by each protocol) and also > considerations on threats and mitigations when combining both > protocols in an application. This will include privacy of the users > and protection of the content distribution. Protection of the content > by Digital Rights Management (DRM) is outside the scope of the PPSP. What is the difference between 'protection of the content distribution' and DRM?

Hi Martin,
   Thanks for the suggestion. As the co-authors, we wish to= =20 address ALL the IESG concerns in the updated draft or replies to the=20 ADs. Actually I replied to Stephen=A3=A8cc to the IESG) to explain th= e purpose=20 of the use cases section(This section is not for the to-do list for the WG= , but=20 for the explanatory effect to show how PPSP could be used in practice). Bu= t I=20 didn't add this in the draft text. This may lead to some confusion when yo= u look=20 into the AD reviews and check the text.
    I think double-check the AD comments is a good=20 suggestion and I'll add some "replies words" to the draft if necessary mor= e than=20 just replying in the email.

Subject: [ppsp] Open issues out of last IESG evaluation f= or=20 draft-ietf-ppsp-problem-statement-10.txt
Hi,
 
I have been through some of the ol= d DISCUSS and COMMENT from the last 
IESG evaluation of draft-ietf-ppsp-problem-statement-0= 7.txt.
 
Here are the ballots with the positions= :
https://datatracker.ietf.org/doc/draft-ietf-ppsp-problem-statement/ba= llot/
 
For instance, a very light one to = be fixed, but I cannot find how this&nb= sp;
is addressed in the -10 version:
 
- Stephen Farrell:
Section 5 really needs to say what = ;sections 5.x are.  They could
be use-cases the WG is going to ta= ckle, or maybe the WG will decide
later, or whatever is the case. Without=  that, its hard to know why
sections 5.x are present.
 
The DISCUSS positions are probably addressed= , but I do strongly 
recommend to double-check all comments.
 
   Martin

Yes, I als= o think it is good idea to double-check and make sure all the discuss and c= omments are addressed in new revision.

Hi Martin,

   Thanks for the= suggestion. As the co-authors, we wish to address ALL the IESG concerns in= the updated draft or replies to the ADs. Actually I replied to Stephen=A3=A8cc to the IESG) t= o explain the purpose of the use cases section(This section is not for the = to-do list for the WG, but for the explanatory effect to show how PPSP could be used = in practice). But I didn't add this in the draft text. This may lead to som= e confusion when you look into the AD reviews and check the text.

    I think = double-check the AD comments is a good suggestion and I'll add some "r= eplies words" to the draft if necessary more than just replying in the email.

Subject: [ppsp] O= pen issues out of last IESG evaluation for draft-ietf-ppsp-problem-statemen= t-10.txt

Hi,

 

I have been = through some of the old DISCUSS and COMM= ENT from the last 

IESG evaluation o= f draft-ietf-ppsp-problem-statement-07.txt.

 

Here are the = ;ballots with the positions:

https://datatracker.ietf.or= g/doc/draft-ietf-ppsp-problem-statement/ballot/

 

For instance, a&n= bsp;very light one to be fixed, but I&nb= sp;cannot find how this 

is addressed in&n= bsp;the -10 version:

 

- Stephen Farrell= :

Section 5 really&= nbsp;needs to say what sections 5.x are. = ; They could

be use-cases the&= nbsp;WG is going to tackle, or maybe the=  WG will decide

later, or whateve= r is the case. Without that, its hard&nb= sp;to know why

sections 5.x are&= nbsp;present.

 

The DISCUSS posit= ions are probably addressed, but I do st= rongly 

recommend to doub= le-check all comments.

Title : Peer-to-Peer Streaming Peer Protocol (PPSPP) Author(s) : Arno Bakker Riccardo Petrocco Victor Grishchenko Filename : draft-ietf-ppsp-peer-protocol-03.txt Pages : 54 Date : 2012-10-21 Abstract: The Peer-to-Peer Streaming Peer Protocol (PPSPP) is a transport 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.

A New Internet-Draft is available from = the on-line Internet-Drafts directories.

Abstract:
   The Peer-to-Peer Streaming Peer = ;Protocol (PPSPP) is a transport
   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&nb= sp;audio/video content.  It is based
   on the peer-to-peer paradigm, w= here clients consuming the content are
   put on equal footing with = the servers initially providing the
   content, to create a system&nbs= p;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 di= fferent mechanisms to optimize peer
   uploading, prevent freeriding, and&n= bsp;work with different peer discovery
   schemes (centralized trackers or&nbs= p;Distributed Hash Tables).  It
   supports multiple methods for c= ontent integrity protection and chunk
   addressing.  Designed as a = ;generic protocol that can run on top o= f
   various transport protocols, it = ;currently runs on top of UDP using
   LEDBAT for congestion control.

Thanks. Hi Yunfei et al there is still a revision history at the back of the document. I will update the tickets soon: Arno -03 2012-10-22 Major revision * Updated Abstract and Introduction, removing download case. * Resolved Ticket #4: Added explicit CHOKE/UNCHOKE messages. * Removed directory lists unused in streaming. * Resolved Ticket #22, #23, #28: Failure behaviour, error codes and dealing with peer crashes. * Resolved Ticket #13: Chunk ranges are the default chunk addressing scheme that all peers MUST support. * Added a section on compatibility between chunk addressing schemes. * Expanded the explanation of Unified Merkle Trees as a method for content integrity protection for live streams. * Added a section on forgetting chunks in live streaming. * Added "End" option to protocol options and corrected bugs in UDP encapsulation, following Karl Knutsson's comments. * Added SHA-2 support for Merkle Hash functions. * Added content integrity protection methods for live streaming to the relevant protocol option. * Added a Live Signature Algorithm protocol option. * Resolved Ticket #24+27: The choice for UDP + LEDBAT as transport has now been reflected in the draft. TCP and RTP encapsulations have been removed. * Superfluous parts of Section 10 on extensibility have been removed. * Removed appendix with Rationale. * Resolved Ticket #21+25: PPSPP currently uses LEDBAT and the DATA and ACK messages now contain the time fields it requires. Should other congestion control algorithms be supported in the future, a protocol option will be added.
