一种基于 CICQ 支持区分 QoS的新型并行交换系统解决方案

摘要

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 .%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。
