Integration of voice, video and data services in a Big 'a' network using anew access protocol

A new high performance multiple access protocol has been proposed for bus L ANs. The efficiency of the proposed network has been analyzed under the new protocol for integration of voice, video and data services. It has been fo und that, for given network parameters, the protocol yields high throughput and less packet delay which is also bounded compared to most of the known collision-prone and collision-free protocols. Also, the protocol is observe d to be suitable for wide-spanned and high-speed networks, and real time ap plications. Recently, fast and wide-band packet switching has emerged as a promising long-term technology for integrated services. The network using t he new access protocol is tested for voice, video and data applications. It is assumed that the service of stream traffic (voice and video) is exhaust ive and data traffic is non-gated. Both interactive and bulk data services are considered. Performance of the network for integration of the above ser vices under the new protocol is compared to that of a collision-prone proto col (the Fast Ethernet), and a collision-free protocol (the Expressnet). It is observed that the new protocol gives better results and is suitable for multimedia applications of wide spanned and high-speed networks. An event driven simulation of the network activities for integrated services of voic e, video and data is carried out for wide range of network parameters and t raffic (stream and data) parameters.
