Comcast's ISP Experiences in a Proactive Network Provider Participation
for P2P (P4P) Technical Trial
Abstract
This document describes the experiences of Comcast, a large cable
broadband Internet Service Provider (ISP) in the U.S., in a Proactive
Network Provider Participation for P2P (P4P) technical trial in July
2008. This trial used P4P iTracker technology, which is being
considered by the IETF as part of the Application Layer Transport
Optimization (ALTO) working group.

1. Introduction
Comcast is a large broadband Internet Service Provider (ISP), based
in the U.S., serving the majority of its customers via cable modem
technology. A trial was conducted in July 2008 with Pando Networks,
Yale, and several ISP members of the P4P working group, which is part
of the Distributed Computing Industry Association (DCIA). Comcast is
a member of the DCIA's P4P Working Group, whose mission is to work
with Internet Service Providers (ISPs), peer-to-peer (P2P) companies,
and technology researchers to develop "P4P" mechanisms, such as so-
called "iTrackers" (hereafter P4P iTrackers), that accelerate
distribution of content and optimize utilization of ISP network
resources. P4P iTrackers theoretically allow P2P networks to
optimize traffic within each ISP, reducing the volume of data
traversing the ISP's infrastructure and creating a more manageable
flow of data. P4P iTrackers can also accelerate P2P downloads for
end users.
P4P's iTracker technology [SIGCOMM] was conceptually discussed with
the IETF at the Peer-to-Peer Infrastructure (P2Pi) Workshop held on
May 28, 2008, at the Massachusetts Institute of Technology (MIT), as
documented in [RFC5594]. This work was discussed in greater detail
at the 72nd meeting of the IETF, in Dublin, Ireland, in the ALTO BoF
(Birds of a Feather meeting) on July 29, 2008. Due to interest from
the community, Comcast shared P4P iTracker trial data at the 73rd
meeting of the IETF, in Minneapolis, Minnesota, in the ALTO BoF on
