P2PSIP list members,

I don't know how many of you are also subscribed to the P2PI mailing list that was for the P2P Infrastructure workshop recently held near Boston, but there's been a great deal of discussion leading to the creation of the Application-Layer Traffic Optimization (ALTO) BOF being scheduled for Dublin. If you aren't aware of the discussions, here's the recent round of documents:

http://www.ietf.org/internet-drafts/draft-kiesel-alto-reqs-00.txt
http://www.ietf.org/internet-drafts/draft-hilt-alto-survey-00.txt (survey of research in the area)

Here's the abstract of the problem statement:

   A significant part of the Internet traffic today is generated by
   peer-to-peer applications used for file sharing, realtime
   communications and live media streaming.  Such applications often
   deal with large amounts of data in direct peer-to-peer connections,
   but they usually have little knowledge of the underlying topology,
   both at the overlay layer and the network layer.  As a result, they
may choose their peers based on measurements and statistics which, in
   some specific situations, often lead to suboptimal choices.  This
   document describes problems related to optimizing traffic generated
   by peer-to-peer applications through the use of link and network
   layer information.

The mailing list is at: https://www.ietf.org/mailman/listinfo/p2pi

Regards,
Dan
