This document describes a protocol and reference architecture that enables the deferred delivery of content to
24、 media client devices. The goal of this protocol is to improve user experience in the delivery of mobile content and reduce streaming congestion within wireless networks where deferred delivery of content is feasible. Content cached on devices is governed by content and network policies, which allow
25、 a content owner, network operator, and user to optimize the retention and consumption of the content. Copyright 2012 IEEE. All rights reserved. ixContents 1.
