Abstract

To improve the efficiency of application layer multicast （ALM）

an hierarchical-ring ALM model based on diff-services （HRM） was presented. In the model

the ring topology was employed to reduce the control overhead. In the data transmission process

the model used push/pull transmission strategy to reduce transmission delay and increase the bandwidth utilization. Simulation results show that the model provides lower end-to-end delay and link stress and control overhead

which is suitable to those larger scale different types ALM applications.
