This paper discusses means to reduce the network traffic load by introducing storage deep in the network-thus avoiding the need for unicast traffic support over the metro or core network-and algorithms to place content intelligently on those storage devices. Heterogeneous communication devices are emerging. An in-depth monitoring regime is required, which performs measurements within different networking devices. A Multimedia Content Management System (MCMS) is proposed to perform dynamic cross-layer adaptation of the IPTV stream based on PQoS measurements at the end-user side. The proposed framework was applied on real data traces from live P2P networks. The 3GPP IP Multimedia Subsystem (IMS) provides a basic architecture framework for the Next Generation Network (NGN) supporting the convergence platform for service provisioning in heterogeneous networks.
