Abstract
A simple mathematical treatment was derived to predict the probability of frame loss for four different models of variable bit rate (VBR) video coding such that access control into a high speed network could be enforced effectively. To maintain a level of quality-of-service (QOS) in broadband ISDN, access to the network is controlled by an edge node. To do that, the node processor must quickly calculate the effect of the video call establishment. If the QOS can not be guaranteed, the call should be blocked. This paper presents some results of signal loss due to multiplexing of more than one VBR video signals. Simple simulation techniques were used for the purpose. Modification of the Markov process was done to model several types video signals. >
