N2 - To guarantee quality of service (QoS), the requirements for video transmission, such as delay and cell loss rate (CLR), are very stringent. These constraints are difficult to meet if high network utilization is desired. In this paper, online dynamic bandwidth allocation algorithms, in which the bandwidth is adjusted based on the current frame size, are proposed to improve the bandwidth utilization. When the bandwidth deviation is large enough, a bandwidth re-negotiation process is triggered. Compared with a constant bit-rate (CBR) service, network utilization can be improved significantly for the same CLR. In general, to achieve a very low CLR and high bandwidth utilization, the re-negotiation frequency may become high. Algorithms which have been proven to be effective in reducing the re-negotiation frequency while keeping the bandwidth utilization at a reasonable level are also proposed.
