A Study on The Traffic Control Using ATM OAM Cell for MPEG Video Service in ATM Networks

ATM 망에서 MPEG 비디오 서비스를 위한 Traffic 동적 할당에 대한 연구

Many recent studies have been conducted involving the transport of constant and variable bit rate MPEG-2 video in asynchronous transfer mode (ATM) networks. In this study, the traffic control of supporting MPEG-2 video communications in ATM networks under unloaded or loaded network conditions, in which the generated traffic sources are bursty in nature, are considered. We analyse about MPEG-2 traffic and design a model, which makes use of the ATM OAM funcation in order to support the traffic control functions. To implement the model, we propose a scheme, which combines the performance management OAM function and the bandwidth allocation function. Especially, we design this scheme to control the VBR (Variable Bit Rate)MPEG-2 video traffic.
