Simple call admission control and buffer management scheme for multiclass video-on-demand service

We investigate and propose a simple and efficient call admission control and buffer management scheme for our recently proposed Video-On-Demand (VOD) system architecture. In this paper we address the multiplexing issue and buffer allocation policy for the system with multiple classes of services, such as different service types and video qualities. Because our proposed algorithm is simple and not relying on the yet unavailable B-ISDN, VOD service can be implemented using the existing high speed circuit switching network
