Abstract

On congested links/routers, Best-Effort delivery will seriously degrade the service provided to the real-time traffic. Real-time audio/video traffics could not depend on the Best-Effort delivery of datagrams, and therefore, like the Differentiated-services (Diffserv) Model, there is a need for a model that can give a per-flow service assurances. This paper discusses issues related to real-time audio/video applications requirements, the trade off between them and the network resources requirements. This paper also states the IP QoS proposed models and presents a comparison between them. Finally, it describes in details the new proposed model which provides end-to-end performance guarantees to support the real-time audio/video traffics on the IP based networks. The new proposed model relies on having an acceptable delay, packet loss, and MTU (Maximum Transfer Unit). It also has an acceptable consumed bandwidth and buffers specially at the core routers in which the congestion usually occurs.
