摘要
针对交换结构所使用的信源模型,不仅要考虑网络业务流自身特性,还要考虑输出端口的业务均衡问题,提出一种可用于交换结构性能分析与设计验证的信源模型,该模型能够产生具有自相似特性的网络业务流,并且能够正确模拟到达交换结构输入端口处的均衡和非均衡分布的网络业务流,同时通过在OPNET仿真平台上的测试,证明了上述结论。该模型对于高速交换机中交换结构的设计具有重要意义。
To design various QoS algorithms implemented in switching tabric, the behavior of the incoming network traffic needs to be taken into account, regarding not only the self similarity of the network traffic, but also the distribution of network traffic at output ports. An OPNET traffic source model to address these problems is presented. Simulation results prove that the model can accurately simulate the behavior of the incoming traffic for switching fabric, which will be very useful in the design of switching fabric in high-speed core touters.
