Part 2: Traffic control in Multimedia Networks An efficient algorithm for multimedia call-admission control

Abstract

This paper presents a call admission control (CAC) algorithm for multimedia communication systems with diverse bit-rate media sources. The proposed algorithm for making bandwidth allocation decisions is based on bounding the probability of demand for excess bandwidth and the loss (or blocking) probability. Recursion formulas for calculating these probabilities are derived. An algorithm based on these probabilities executes quickly enough so that the response time to a bandwidth request is acceptable.
