METHOD OF ADMISSION CONTROL FOR PACKETIZED COMMUNICATION NETWORKS

摘要

A method is disclosed for determining the admissibility of an offered sessi on of traffic of a specified class to a server in a packetized communication network. Each class c has a peak traffic rate r(c). The server has a total processing rate C. Admitted packets are scheduled according to an EDF scheduling discipline. T he method for determining admissibility comprises defining an operating point f or the server. The operating point represents.the number of sessions N c of each respective class currently offered or currently being served. The method further comprises determining whether the defined operating point falls within a set of operating points that together define an admissible region. The admissible region consists of operating points for which the probability of violating a delay bound for an y packet is below a threshold. The determination of the admissible region involves principles of statistical multiplexing.
