The IESG has approved the following document: - 'DECoupled Application Data Enroute (DECADE) Problem Statement' (draft-ietf-decade-problem-statement-06.txt) as Informational RFC This document is the product of the Decoupled Application Data Enroute Working Group. The IESG contact persons are Martin Stiemerling and Wesley Eddy. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-decade-problem-statement/ Technical Summary Peer-to-peer (P2P) applications have become widely used on the Internet today and make up a large portion of the traffic in many networks. In P2P applications, one technique for reducing the transit and uplink P2P traffic is to introduce storage capabilities within the network. Traditional caches (e.g., P2P and Web caches) provide such storage, but they are complex (due to explicitly supporting individual P2P application protocols and cache refresh mechanisms) and they do not allow users to manage access to content in the cache. For example, content providers wishing to use in- network storage cannot easily control cache access and resource usage policies to satisfy their own requirements. This document discusses the introduction of in-network storage for P2P applications, and shows the need for a standard protocol for accessing this storage. Working Group Summary The WG strongly supports this document for publication. Many WG members have read and agreed with it. Document Quality This is a problem statement document, and provides the motivations for the DECADE effort and its scope. Optimizing peer-to-peer applications are the primary motivation for DECADE, and the document authors and reviewers are well- versed in P2P technology. The document was reviewed by DECADE WG members, the WG Chairs, and key non-WG contributors, particularly by Akbar Rahman, Roni Even, David Bryan, Ning Zong, Börje Ohlmann and Tao Ma.
