基于动态MSN的软交换多业务环境性能研究

The Performance Study of Softswitch Multi-Service Environment Based on Dynamic MSN

在下一代网络中将提供具有不同性能要求的语音、数据和多媒体业务,研究这些业务性能的相互影响并采用有效的方法保证这些业务的性能指标对下一代网络的成功实施具有重要意义.本文设计了一种多队列的软交换多业务控制框架,在此基础上提出并分析了一种动态最大会话数(MSN,Maximum Session Number)方法来分配系统资源,以有效利用系统资源确保业务性能.仿真结果表明:在软交换多业务环境中,采用动态MSN方法能确保系统的稳定性并有效地满足各种软交换业务的性能要求.

The next generation network will provide voice,data and multimedia services,which are with different performance requirements. To research the impact of these services＇ performances between each other and to assure these performances is significant to implement the next generation network successfully. The paper designs a softswitch multi-service control framework with multiqueue, and a dynamic MSN（maximum session number） method to allocate system resources is proposed and analyzed to effectively utilize system resources to insure service＇ s performances, which are based on the control framework. The simulation results prove that the dynamic MSN can ensure the system＇s stability and satisfy each softswitch service＇ s performance requirement in the softswitch multiservice environment.
