Abstract :
When a Banyan switch is used to switch variable bit rate (VBR) video, some video packets may not be switched before their deadlines because the VBR video sources may temporarily generate heavy traffic or they only generate moderate traffic but some video packets encounter internal blocking in the switch. Therefore, some video packets may be discarded. We determine the condition of packet loss and then derive the packet loss probability. Based on this result, we perform admission control to determine whether a given video session can be admitted while the resulting packet loss probability is still small enough to guarantee a good image quality
