Handoff Optimization for Multicast Streaming

This chapter proposes a few optimization techniques that expedite the delivery of a multicast stream during handoff in a hierarchically scoped multicast architecture. First, the chapter proposes a hierarchically scoped multicast content distribution network, describe the functional components of the architecture and their implementation. It then introduces optimization techniques that reduce the join and leave latencies for multicast traffic, and compares performance results for both optimized and non-optimized handoffs. These optimization techniques can be used to provide fast delivery of multicast traffic in a hierarchically scoped multicast environment. These proposed techniques could be applicable to mobile content distribution networks.
