基于CICQ结构的交换机建模与仿真

Modeling and Simulation of Switch Based on CICQ Architecture

利用OPNET软件完成了基于CICQ交换结构和LQD_RR调度算法的交换机模型构建,并且在交换机工作的真实环境基础上,使用OPNET模拟了交换机外围的节点和进程模型,最后在不同流量模型下完成了交换机的仿真。通过分析仿真结果对交换结构以及算法进行评估,方便后期的硬件设计,避免在硬件设计过程中因算法可行性分析不充分而影响整个设计流程。

Software OPNET is used to complete a switch system with CICQ architecture and LQD_RR scheduling. For the purpose of simulating the real working environment of the switch, the peripheral nodes are created based on traffic distribution. Finally switch simulation is completed under different traffic models. The results of simulation are analyzed to evaluate the performance of switching architecture and algorithm which make hardware design easily and prevent the unsufficient feasibility analysis on the entire design flow during the hardware design process.
