   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.
