A true VoD system has tremendous demand in the market. The existing VoD system does not cater the needs and demands of the market. The major problem in the VoD system is serving of clients with expected QoS is difficult. In this paper, we proposed a protocol and algorithm that chains the proxy servers and subscribed clients. Our objective is to send one server stream and this stream should be served to N asynchronous clients. The server bandwidth is scarcity and on the client uplink bandwidth is underutilized. In this protocol, we are using client’s residual bandwidth such that the load on the server bandwidth is reduced. We have proved that optimal utilization of the buffer and bandwidth for the entire VoD system and also less rejection ratio of the clients.
