Optimisation of Distributed Exchange Control Systems

摘要

New telecommunications services have emerged which will place quite disparate processing demands on the control systems of exchanges and the optimal system configuration will depend on the call mix to be supported by the exchange. A cost effective distributed control system design in the ISDN and IN environments can be achieved by combining optimal placement of software functionality and optimal choice of capacities for the processing elements. Two control system models based on queueing networks and able to capture the features of the system at different levels of detail are developed and used to produce distributed control system optimisation algorithms. These algorithms can assist system designers in producing optimal control systems which are required to satisfy particular uniform load specifications and performance constraints. Simple examples indicate the range of applicability of the developed algorithms.
