UltraSAN version 3: architecture, features, and implementation

摘要

This paper describes version three of UltraSAN, a software environment for the performance, dependeability, and performability evaluation of computer net-works and systems. The package makes use of both analytic -and simulation-based solution methods using a single, high-level, representation known as stochastic activity networks. Version three, just copleted, contains significant enhancements, relative to the earlier versions, in model specification, construction, and solution.
