摘要
In this paper, we present design of a large self routing multicast ATM switch. The switch consists of a sorting network followed by a 3-stage routing network. We first present a simple design of a large sorting network, built using small sized shared memory that can be used as a building block for a large sorting network. Small sized shared memory are also used in the 3-stage routing network making the switch modular and easy to implement using current VLSI technology. As the network uses shared memory modules, multicasting functionality is easily built into the network. The performance of the proposed network is compared with an equivalent completely shared memory switch using computer simulations under bursty traffic model. The results show that the proposed network has better performance in terms of cell loss rate than the completely shared memory switch under moderate to heavy traffic load (0.6 less than or equal to Effective Offered Load less than or equal to 1.2). Furthermore, multicast cell delays are drastically improved.
