Distributed applications -- such as file sharing, real-time
communication, and live and on-demand media streaming -- prevalent on
the Internet use a significant amount of network resources.  Such
applications often transfer large amounts of data through connections
established between nodes distributed across the Internet with little
knowledge of the underlying network topology.  Some applications are
so designed that they choose a random subset of peers from a larger
set with which to exchange data.  Absent any topology information
guiding such choices, or acting on suboptimal or local information
obtained from measurements and statistics, these applications often
make less than desirable choices.

This document discusses issues related to an information-sharing
service that enables applications to perform better-than-random peer
selection.  This memo provides information for the Internet community.

This document is a product of the Application-Layer Traffic Optimization Working Group of the IETF.
