Abstract

Shared-memory based packet switches are increasingly being used for high-performance Internet switches and routers. The shared-memory switches are known to provide better throughput and packet-loss performance for bursty data traffic in high-speed networks and Internets compared with other buffering strategies under conditions of identical memory resource deployed in the shared-memory switch. The scheme to share the common memory resource among various broadband lines has direct impact on the throughput and packet-loss performance of the switch. In this paper, we compare the effect of unbalanced bursty traffic on commonly used memory-sharing schemes, namely the individual-static threshold based, global-static threshold based, dynamic threshold based and SMDA based memory-sharing schemes.
