Abstract :
The bandwidth requirements for variable bit rate (VBR) traffic such as compressed video shows a dramatic variation over different time intervals. Allocating a bandwidth at the 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. 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.
