MEEAC: An enhanced scheme for supporting QoS granularity by multipath explicit endpoint admission control

The international research community has been working for the last decade on designing solutions for the QoS in Internet. There has been a dramatic increase in the processing power of workstations and bandwidth of high speed networks. This has given rise to new real-time applications such as multimedia. These applications have traffic characteristics and performance requirements that are quite different from existing data-oriented applications. Supporting QoS in packet switching networks requires specialized infrastructure to be designed and developed. The Intserv framework aimed at providing per-flow QoS guarantees to individual application sessions. The scaling properties of the Diffserv architectural framework are achieved by marking each packet´s header with one of the standardized codepoints. This paper proposes a new approach for improvement of EEAC-SV model, in order to supporting QoS granularity, by creating multiple paths in the network and selecting capability in source nodes. The simulation result shows the granularity of QoS in the proposed model is better than EEAC-SV model.
