Packet Delay Evaluation Using M/G/WFQ Model

An actual problem is how to evaluate the quality of IP network. Differentiated Services is a promising architecture for the next generation Internet due to its highly flexible, scalable and interoperable design. In Differentiated Services, scheduling disciplines play an important role in achieving service differentiation. In this paper two queuing models are pending: M/G/WFQ and M/G/1/p3. Thus we are considering, which model can better support quality of services with the lowest difference of delay between data packets. Key-Words: IP network, Differentiated Services, Quality of Service, Class of Service, Queuing discipline, M/G/1/WFQ, M/G/1/p5.
