摘　　要：在对现有的PPS机制分析研究的基础上,提出一种基于CICQ支持区分QoS的新型并行交换系统PSVIOQ-CICQ解决方案。该方案设计中采用虚拟队列技术,输入缓存设置成N个VOQ,与负载均衡器协同完成负载均衡分配,输出缓存设置成N个VIQ,与分组整合器协同完成信元的按序转发并提供QoS保障。仿真表明PSVIOQ-CICQ具有较好的公平性和负载均衡性,整体达到了设计目标要求。Based on in-depth study and analysis on existing parallel packet switching （PPS） mechanism, we propose a solution for novel parallel switching system PSVIOQ-CICQ, which is based on CICQ and supports differentiated quality of service （QoS）. In the design scheme it adopts virtual queue technology. The input buffer is set to N VOQ, and collaborates with the load balancer to complete the balanced load allocation. The output buffer is set to N VIQ, and collaborates with the cell integrator to complete the sequential forward of cells and provides QoS support. Simulation shows that PSVIOQ-CICQ has good fairness and load balancing, and reaches in whole the requirement of design target.
