Abstract :
Due to the advance in WDM technology and real-time applications, multicast communication is discussed recently. An important issue for real-time communication, fault restoration schemes, lets multicast communication reliable. In this paper, a novel QoS restoration scheme based on domination set (HFR-DS) is proposed. The domination node can provide dynamic method to generate the restoration path. This method is not only used for link failure, but also for node failure. The simulation results show that the proposed scheme has better performance in terms of hop count and blocking probability. The delay could be guaranteed to meet the requirements of different kinds of multicast group, such as real-time streams.
