Design a Hierarchical Cache System for Effective Loss Recovery in Reliable Multicast
Packet loss recovery is a key issue in reliable multicast. An effective way for packet loss recovery is to place repair servers with active routers along the transmission paths. These repair servers naturally form a hierarchical cache system due to the hierarchical nature of the multicast tree. How to design an effective hierarchical cache system to minimize the packet loss is important. In this paper, we first derive a cooperative caching efficiency model for a hierarchical cache system. Based on the model, a heuristic Cooperative Cache Replacement (CCR) algorithm is proposed to achieve efficient cache performance for reliable multicast systems. The implementation issues are also discussed in detail. The ns-2 based simulations are conducted to evaluate the performance of the proposed algorithm by compared to the optimal caching time (OCT) based algorithm. The results show that CCR effectively reduces the packet loss recovery latency.
