Speedup Banyan 스위치를 이용한 대규모 ATM스위치의 설계에 관한 연구

In this Paper, We propose a speedup Banyan ATM switch to improve the throughput and the cell loss rate. And, we also propose a large-scale ATM switch with ,two stage, which is based on proposed unit switch. The first stage is consist of binary tree and speedup Banyan switch for expanding network. And the second stage is consist of multiplexers for concentrating network. In order to evaluating the performance of the proposed switches, we analyze states of switch and compute the probability of each state using Markov chain. The factors of performance evaluation are the cell loss rate of internal and output buffer and the normalized throughput of switch in terms of variable speedup factors, the size of switch, and the size of output buffer.
