Multicast QoS Provisioning under Enhanced Admission Control for Multicast

Authors : I. Sathik Ali and P. Sheik Abdul Khader

Abstract: Real-time applications such as multimedia streaming and video conferencing have quite stringent Quality of Service (QoS) requirements from the network because they are more sensitive to available bandwidth and loss rate than non real-time traffic. To provide scalable and simple Quality of Service (QoS) mechanism for multicast services, Probe-Based Multicast Admission Control (PBMAC) scheme was proposed. In this study, the subsequent request problem found in PBMAC which degrades system performance significantly when the network traffic is heavily loaded is investigated. Based on the investigation of the subsequent request problem, an enhanced scheme called Enhanced Admission Control for Multicast (EACM) is then proposed. The simulation shows that this EACM scheme results in reduction of the bandwidth requirement for probing process and increase of the available bandwidth in the bottleneck link of network.
