Bandwidth requirements for Variable Bit Rate (VBR) traffic such, as compressed video, shows a dramatic variation over different time intervals. Allocating a bandwidth at peak bit rate for the entire call duration will guarantee the quality of service (QoS) but this result in poor network resources utilization. We have proposed an alternative approach that renegotiates the allocated bandwidth and QoS during the lifetime of the connection. In this paper, we present the results of a performance evaluation for the proposed renegotiation-based dynamic bandwidth allocation scheme. In particular, we determine the impact of the renegotiation frequency on the network performance.
