Simulation: a tool for performance evaluation in network computers

The success or failure of network computers in today's highly competitive market will be determined by system performance. Consequently, existing network computer configurations are constantly being modified, extended, and hopefully, improved. The key question pertaining to the implementation of proposed changes is "Does the proposed change improve the existing system performance?" Unless techniques are developed for measuring system performance, network computers will remain expensive toys for researchers, instead of becoming cost effective tools for progress.
