Abstract

Recently, multimedia communication services, such as video conferencing and voice over IP, have been rapidly spread. H.323 is an international standard that specifies the components, protocols and procedures that provide multimedia communication services of real-time audio, video, and data communications over packet networks, including IP based networks. H.323 is applied to many commercial services because it supports various network environments and has a good performance. But communication services based on H.323 may have some problems because of current network trouble or mis-implementation of H.323. This paper concentrates on the transmission of video over wide switched LAN. This study is orientated to simulate a surveillance video network in a wide LAN. This LAN has been designed with Video Servers as source of data "such as Mpeg4 and wavelet video codecs" and PCs as Video Clients. All Video Clients are situated in a Control Centre. The network was split in four sections: Main Backbone, Secondary Backbone, Access Network and Control Centre; after applying the simulation, the throughput, delay and packet loss parameters are measured, to know the best transmission in the worst case and how many numbers of flow supported by Gigabit link.
