摘要
对异步光突发交换网络中单波长光缓存进行仿真建模并辅以分析,介绍了当前已有的理论并用其验证仿真结果。用不同的信道资源分配算法进行仿真并比较结果,指出光缓存中缓存粒度最佳值的设置不仅和突发包的平均长度以及负载有关,而且与核心结点所采用的调度算法有关。
Single wavelength optical buffer in the asynchronous optical burst switching network is simulated, modeled and analyzed. The existing theory is introduced and used to verify simulating results. Different channel resource allocating algorithms are used to simulate and compare the results. It is indicated that the optimal value of buffer granularity is not only related to the mean burst length and load,but also to the scheduling algorithms adopted by the core nodes.
