Research of Application Layer Multicast Model Based on Wheel-Tree Architecture
Ying Yan · Computer Knowledge and Technology · 2011
To combine the advantages of tree and ring architectures and improve the transmission efficiency of the Application Layer Multi cast(ALM),this paper presents one new ALM model which constructs an overlay network based on Wheel-Tree.In this model,we use a localized process to gather those nodes with short distances together and form one wheel structure,so as to build a binary tree with the min imum delay to improve data forwarding efficiency.Simulation results show that this model could be used in the large-scale and real-time environments,and have a lower end-to-end delay and link stress,as well as smaller link stretch and control overhead.
