摘　　要：提出了一种无缓存光分组交换机搭建的平坦型数据中心网络架构——架顶平坦互联,并在OMNe T++仿真平台上对架顶平坦互联架构进行仿真实验,得到架顶平坦互联架构在不同业务分布、不同业务模式和不同缓存容量条件下的系统平均时延、分组丢失率和吞吐率的仿真结果.结果表明,基于端口无缓存光交换机的架顶平坦互联架构数据中心网络具有良好的时延特性、网络吞吐率、可扩展性和成本效益.The performance of a new flat data center network（ DCN） architecture top of rack（ ToR）connected flatten（ TCF） was investigated based on distributed buffer-less optical switches and fast flow control. Scalability of DCN is assessed by numerical simulation with objective modular network testbed in C ＋ ＋（ OMNe T ＋ ＋） discrete event simulator,while the average latency,packet loss and throughput of the system are obtained under different traffic patterns,different traffic distributions and various buffer sizes. It demonstrates that TCF based on distributed buffer-less optical switches not only has good latency characteristic and system throughput,but also has fine scalability and cost efficiency.
