Quality of Service Assurances in Multimedia Network: A Simulation Approach

摘要

QoS is not a consideration at the beginning of the development of IP networks. However, as its growth and support more services including critical and real-time services, QoS support is indispensable. Multimedia applications require different QoS requirements from simple network applications. Multimedia services need more bandwidth, lossless delivery, and strict delay. IP networks treat all traffic, in the same way, this will be a problem for real-time traffic likes multimedia applications. This project uses Multi-Protocol Label Switching (MPLS) and DiffServ QoS management schemes to meet the quality of service requirement in multimedia networks. The aim of this study shows that two methods can improve network performance for multimedia type applications. An analysis to compare the quality of service guarantees provided by these models using a simulation approach. Based on simulation results and analysis shows that two methods improved network performance for multimedia type applications in massive traffic environments.
