摘　　要：主要研究在Parlay多业务环境中,在不同负载情况下,由软交换发起的业务和由Web服务器发起的业务之间性能的相互影响,提出了在这些业务间动态分配系统资源的方法,并在保证系统稳定性的前提下,提出使用会话建立时延约束(SSDB)机制确保各业务的吞吐量、请求响应时间等性能指标.仿真结果表明,结合SSDB机制的系统资源动态分配能有效地满足下一代网络多业务环境中各业务性能的要求.The mutual performance influence in different load cases about softswitch service and web service in the Parlay multi-service environment were studied. The dynamic resources allocation method between these services was proposed. Taking the stability of system as the prerequisite, SSDB （session setup delay-bound） mechanism was proposed to satisfy each service＇ s performance requirement on throughput and average response time. The simulation results prove that dynamic allocation of the system resource based on SSDB can satisfy each service＇s performance requirement in this environment.
