In today's diverse network environments

the interoperability protocols play an important role in performance of application sy stems.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 quantities 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.
