Dual parent multicast graph for failure resilient peer-to-peer multimedia streaming

2006 
Failure resiliency is one of major concerns in design- ing peer-to-peer systems for continuous multimedia streaming since peers can leave or fail without notices. Building resilient multicast networks based on parent multiplicity is an approach to combat network failures and improve stream continuity. In this paper, we model the problem of generating resilient multicast graphs with parent multiplicity, called Dual Parent Multicast Graph (DPMG), as two sub-problems: constructing a regular graph on a set of labeled vertices; and labeling edges of that graph. Our proposed algorithms to solve the two sub-problems produce a DPMG with good resiliency property especially for locally and burstly occurred failures in peer-to-peer networks.
