An End-To-End IPTV Broadcast Service Network Architecture

This paper introduces an IPTV broadcast service delivery network architecture for digital multimedia distribution from national and regional video head-ends to service subscribers in a scalable, cost efficient, and reliable manner. The architecture presents a managed solution for broadcasting digital television, where its minimum-cost (Steiner) tree structure ensures significant bandwidth savings in the core, and its intelligent IGMP snooping Aggregation and Access nodes provide fast channel zapping, subscriber authorization, and channel profiling. The architecture is scalable, manageable, bandwidth efficient, reliable, and compliant with reference architectures from the DSL Forum as in [1]. Mechanisms for adaptive distribution of traffic flow in the network, failure detection and recovery, along with various characteristics of the said architecture are presented briefly.
