The importance of computer network performability, the combination of performance and reliability, is evident in industry. This paper provides an efficiently computable measure of perfoimability in packet switching networks. The impact of the network's reliability on response time is examined. As a measure of response time, we use packet delivery, the probability Pr(τ ≤ t) that the delay τ for a packet transmission does not exceed a specified time t. Delay of a packet results if the system is busy servicing other packets or if equipment in the network is malfunctioning. Our method of estimating performability for complex packet switching networks is based on constructing a bounding structure whose packet delivery is a lower bound on the packet delivery in the underlying network. The method proposed can be used also for evaluation and improvement of the response time for the problem of transaction processing for different network configurations.
