Hi, Schmidt,

 

Your suggestion is good, although I think this new text could be in
explanatory text rather than in the formal requirement body.

BTW, I have post a new revision -02 and forward the message to the list, but
it seems that it doesn’t come out. So I attached the link to the new
version as below

 

http://tools.ietf.org/html/draft-ietf-ppsp-reqs-02

The main differences between -02 and -01 can be found in:

http://tools.ietf.org/rfcdiff?url2=draft-ietf-ppsp-reqs-02.txt

 

BR,

Ning Zong

Hi Yunfei,

 

a proposal related to PPSP.REQ-7:

 

   “PPSP.REQ-7: The Tracker Protocol and Peer Protocol SHOULD enable

   peers to receive streaming data within the time constraints required

   by specific content items.”

 

CS: We should be a little bit more specific here. I think, that delay will

be the most critical QoS issues, especially for p2p live streaming.

We should add:

 

Proposal:

   “PPSP.REQ-7: The Tracker Protocol and Peer Protocol SHOULD enable

   peers to receive streaming data within the time constraints required

   by specific content items. End to end delay will become critical in case

   of live streaming. Especially In provisioning of sports events, 

  end to end delay of 1 minute and more seems to be not acceptable.”

 

What do you think about?

Best Regards

Christian
