中文摘要：

本文提出了一种新的适用于OCDMA网络的地址码分配策略，并采用新的数学模型——处理器共享系统，对OCDMA网络的稳态吞吐率和平均时延进行了仿真计算，结果表明，本文提出的分配策略的性能优于目前文献中已报道的策略；采用处理机共享系统模型的仿真结果与实际情况非常吻合，它比传统的马尔可夫链模型简单，适合用于对OCDMA接入网进行建模。

英文摘要：

A new codeword assignment strategy for OCDMA networks is proposed in this paper. Employing a new mathematical model, namely processor-sharing system, static-state throughput ratio and average delay of OCDMA networks are calculated, The results reveal that our strategy performs better than existing strategies. Meanwhile, analysis process is simplified compared with conventional Markov chain model, and corresponding results are indeed consistent with practical situation, thus processor-sharing system is truly applicable to model the OCDMA networks.
