A Complex System Characterization of Modern Telecommunication Services

A modern telecommunication service is portrayed as a complex system and is characterized by its stochastical attributes and fuzzy performance considerations. Asynchronous transfer mode (ATM) telecommunication is studied as an example of such a complex system. A call admission control (CAC) procedure is developed using a fuzzy inference method applied to the complex connection patterns of ATM service. Such an inference alleviates the potentially over-conservative nature of resource allocation. A complex system parameter is defined and used as a fuzzy variable in the inference strategies pursued. Some practical considerations and merits of the present study are indicated and discussed.
