In this paper, we analyze the stream building processes in P2P streaming systems. A stream building process (SBP) is defined as the process that a peer tries to build enough download streams. We argue that a SBP can be roughly seen as a stochastic process composed by random events of stream test, and the time cost of SBP statistically depends on the sequence of requested peers. By modeling the probability...
In the context of application layer multicast (ALM), quality of high-bandwidth real-time communication over best effort networks is mainly constrained by node capacity and link loss characteristics observed along multicast delivery path. Our ALM solution is based upon cluster-oriented, regular and multi-trees (CORM) structure and can overcome these constraints by adequately supporting loss recovery,...
Real-time multicast is widely applied on Internet. Unfortunately, current systems share the same problem that they are not able to maintain high and stable performance when the scale grows unexpectedly large or the nodes' performance fluctuation drastically. This paper attempts to solve the problem by means of network structure clustering and constraints. We show that the multicast network can achieve...
