Performance modeling and evaluation of samis computer network using paws

Abstract EN

A high level performance modeling and evaluation software tool called PAWS is introduced, and its application to modeling the hardware and software of the SAMIS Online System to evaluate its performance is demonstrated.

Properties of the SAMIS Online System are first presented.

Some of the important simulation language structures available in PAWS are briefly described, and their ease of use and functionality are discussed.

Problems encountered during the performance modeling process are discussed and procedures that are adopted to create a successful model representing the actual system are presented.

Two models using the PAWS language are also described together with the modeling assumptions and the reasoning behind the assumptions.

Finally, the results obtained through modeling and suggestions to improve the system performance are presented.
