Technical Summary
This document reports the outcome of a workshop organized by the
Real-time Applications and Infrastructure Area Directors of the IETF
to discuss network delay and congestion issues resulting from
increased P2P traffic volumes. The workshop was held on May 28, 2008
at MIT in Cambridge, MA, USA. The goals of the workshop were
twofold: to understand the technical problems ISPs and end users are
experiencing as a result of high volumes of P2P traffic, and to begin
to understand how the IETF may be helpful in addressing these
problems.

The reference with anchor [RFC2474] points to RFC2475. Please fix it to
read RFC2474.
Please make the following changes to draft-p2pi-cooper-workshop-report:
(1) In Section 2, please insert the following sentence after the first
sentence in the second paragraph:
The general class of congestion problems attributable to always-on,
high-volume applications require the development of solutions that are
reasonable for operators, applications, and subscribers.
(2) In Section 2, in the sentence below, please change the word "may" to
"will likely":
Although the workshop focused primarily on the specific causes and
effects of current P2P traffic volumes, it may be useful in the future for
the IETF to consider how to pursue solutions to these larger problems.
(3) In Section 4, please add the following sentence to the end of the
last paragraph:
Even users with dedicated bandwidth can experience delays as their own
P2P traffic saturates the link and dominates their own more
latency-sensitive traffic.
