Research output: Contribution to conferencePaper


This paper describes version three of UltraSAN, a software environment for the performance, dependability, and performability evaluation of computer networks 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 completed, contains significant enhancements, relative to the earlier versions, in model specification, construction, and solution.
