软交换处理能力预测与资源优化分配策略研究

Throughput Prediction and Optimal Processing Capacity Allocation of Softswitch

针对多进程共享单个处理机的软交换实体,提出一种基于会话的性能分析模型.根据该模型,指出在处理机能力给定时,软交换实体能够达到的平均会话吞吐率的上限.并提出一种软交换内部不同进程共享处理机资源的最佳分配策略,该策略使得平均会话建立延迟最小.

A session-based performance model of softswitch entity with multiple processes sharing single CPU (central processing unit) architecture is raised out. According to this model, the maximum session throughput of softswitch is predicted with the constraint of finite CPU processing capacity. An optimal processing capacity allocation policy is also proposed, which could minimize the mean call setup delay.
