Multi-source overlay multicast model of dynamic QoS-constrained based on P2P network
Zhao Shu-feng · Journal of Computer Applications · 2009
A multi-source overlay multicast model was built to solve the problem of Quality of Service(QoS) multicast in overlay network.In this model,each node maintained the local state information instead of one tree per source,and the model delivered multicast message in a way similar to flooding.By controlling,the message transmission path formed a tree structure.The multicast tree can dynamically adjust and adapt to a different source node initiated multicast applications,which meets the requirements of QoS.The experimental results show that multicast coverage rate of the model is high,and the cost of adjusting the multicast tree can be the lowest by controlling the number of sub-node of modes.
