ATM-over-DSL is a promising access technology for video-on-demand (VOD) service. In order to meet the Quality-of-Service (QoS) requirements of the VOD service and maximize the network throughput, it is essential that the call admission control algorithm be carefully designed. In this paper, we propose a new admission control scheme for the VBR MPEG video in the VOD system over ATM-over-DSL access networks. In the proposed scheme, when a new video call is requested, the video server first determines the I-frame starting time of the new video call which can minimize the cell loss ratio (CLR) of the multiplexed traffic and then decides if the VOD system can provide the video call with its negotiated QoS without violating the QoS guarantees of existing calls in the network. Experimental results show that the proposed admission control method can calculate the number of acceptable sources more precisely and efficiently than other existing methods.
