Abstract

The deployment of scalable audiovisual multicast services over heterogeneous core and access networks is a challenging problem. In this article we propose E-Cast, an efficient, source-specific, scalable, overlay multicast system based on the peer-to-peer system Kademlia. This novel overlay multicast system enables IPTV multicast to be deployed as a service level infrastructure to overcome IP network multicast discontinuity in converging wired and wireless network domains. E-cast consists of a set of edge devices called E-Cast Service Node (ESN) and one managing device called E-Cast Service Manager (ESM). ESNs are distributed in the network and provide efficient video distribution services. They not only transport the media-streaming but also can cache the media files according to some given criteria. Performance evaluation using simulation and features comparison with existing proposals are also proposed.
