Two Methods of Controlling Point-to-Point Loss Probabilities in a Circuit Switched Network.
Abstract
The existing program for the design of OS/AUTOVON networks determines the link sizes for the given network connectivity, traffic loads, routing plan and link blocking probabilities. If the resulting point-to-point loss probabilities are unacceptably high or too low (resulting in large link sizes), the link blocking probabilities need manual adjustment. The desired adjustment is not known and can only be assessed by experimenting with a large number of sets of link blocking probabilities and examining the resultant link sizes and point-to-point loss probabilities. Our search for methods to automatically resize the links using the feedback principle and thereby improve the design of a network led to identification of two methods: (1) Link GOS Adjustment method and (2) Link Size Adjustment method. Test results showed that the first method can effectively bring the point-to-point loss probability of traffic to within the specified GOS with fewer interswitch trunks. The second method maximized the number of source-destination pairs whose point-to-point loss probabilities are between the specified lower and upper bounds, although it involved more hops for completed calls and more interswitch trunks.
