The IESG has approved the following document: - 'Application-Layer Traffic Optimization (ALTO) Problem Statement ' <draft-ietf-alto-problem-statement-04.txt> as an Informational RFC This document is the product of the Application-Layer Traffic Optimization Working Group. The IESG contact persons are Lisa Dusseault and Alexey Melnikov. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-alto-problem-statement-04.txt Technical Summary Peer-to-peer applications, such as file sharing, real-time communication, and live and on-demand media streaming use a significant amount of Internet resources. Such applications often transfer large amounts of data in peer-to-peer connections. However, they usually have little knowledge of the underlying network topology. As a result, they may choose their peers randomly with respect to the underlying network topology or they may choose their peers based on measurements and statistics that, in many situations, may lead to suboptimal choices. This document describes problems related to improving traffic generated by peer-to-peer applications. In particular, this document discusses issues which better-than- random peer selection based on network-layer information may raise. Working Group Summary This document is the problem statement that accompained the chartering process of the ALTO WG. Document Quality The document has received extended review by WG members and TSV experts. Personnel Lisa Dusseault is the responsible Area Director. Jon Peterson is the shepherd. _______________________________________________ IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
