摘　　要：通过对数据传输流程的分析,建立了IP存储广域网的排队网络模型.在此基础上,提出了IP存储广域网的性能边界分析模型.实验结果发现,实测性能在理论性能边界范围之内,理论性能边界反映了实测性能的变化趋势.对模型的分析表明,IPWAN的性能是限制IP存储广域网最大性能的关键因素,提高缓存命中率、链路带宽和降低传播延迟将提高IP存储广域网的最大性能.Based on the data transfer process of IP-SWAN （Storage Wide Area Network）, a queueing network model of IP-SWAN is established. At the basis of the model, performance bounds analysis model of IP-SWAN is proposed. The theoretical results are compared with the test results, and found to be in agreement. The model analysis shows that performance of IP WAN is the key factor that restricts the maximum performance of IP-SWAN, and the maximum performance of IP-SWAN can be improved by enhancing cache hit rate .increasing link bandwidth and decreasing transmission delay.
