摘要
在异构网络环境下,互操作协议对应用系统具有重要意义,互操作协议的性能对应用系统的性能也起着举足轻重的作用.为确定应用系统性能瓶颈,必须评估互操作协议性能.本文提出了一种互操作协议性能评估方法.该方法针对实际应用系统中的互操作协议,提出符合实际的评估指标,对协议性能进行定性分析和定量分析.在定性分析中得出安全性、容错能力、可扩展性等性能指标.在定量分析中,建立仿真实验模型与排队论数学模型相结合的混合模型,得出网络带宽占用、响应时间与吞吐量等性能指标.综合这些指标,我们给出互操作协议性能评估的结果.
In today＇s diverse network environments, the interoperability protocols play an important role in performance of application systems. To assist performance assessments of application systems, we have proposed an approach to assess performance of interoperability protocols. The approach takes the real conditions of the system into account and proposes assessment criteria to make reasonable qualitative and quantitative performance analysis of interoperability protocols. In qualitative analysis, we obtain security ,fault-tolerability, scalability, etc. In quantitative analysis, we build up an experimental model and a math model to obtain performance quantifies such as response time, net bandwidth, and throughput. Finally, according to the criteria we have proposed, we produce the result of performance assessment of interoperability protocols.
