Title A comparative study between combination of PQ and MWRR Queuing techniques in IP network based on OPNET
Authors Farhangi, Sajad; Golmohammadi, Saeed
Abstract Today’s Internet only provides best effort service and traffic is processed quickly, but there is no guarantee for the timely delivery of data. So, the ability to provide flow based quality of service (QoS) support has become very important for the design of modern switches and routers. With the development of the Internet network in recent years, a variety of novel Internet multimedia applications, such as voice over IP and videoconferencing, have been developed, which usually have different quality of service requirements. Priority Queuing (PQ) and Modified Weighted Round Robin (MWRR) Queuing have been proposed, because of their better performance for real-time applications traffic. In this paper, we investigate the combinations of queuing methods and study their impact on the performance network. We demonstrate that with combination of MWRR and PQ queuing techniques better results rather than single configuration of MWRR and PQ queuing in Ethernet delay, Email download response time, Ftp download response time, HTTP object response time, end-to-end delay for voice traffic and IP Processing delay parameters.
