Application layer multicast algorithm based on Mesh-first for P2P streaming media
Zhenyu Zhong · Journal of Computer Applications · 2011
Peer-to-Peer(P2P) streaming media on the Web has been developed and applied widely.The algorithm of streaming system in multicast tree construction of application layer will directly affect the overall system efficiency and quality.A new service framework for distributed application layer overlay multicast tree construction algorithm—CDDMA(Constraint of Delay and Degree Mesh-based Algorithm) was presented in this paper.The transmission delay and node degree constraints were taken into account in CDDMA,and the traditional load imbalance problem of application-level multicast tree could be solved by CDDMA.Take SMesh for example,this paper showed how to balance load by using CDDMA,through simulations on Internet-like topologies,the results show that CDDMA achieves low Average Path Stretch(APS) and low Average Link Stress(ALS).
