Abstract

An exchange route decision system and method which, when it is desired to realize tandem connection between outgoing and incoming communication terminals of various sorts and multiple rates requiring immediate data communication through a plurality of exchanges, take the residual capacities of relay lines between the outgoing and incoming terminals into consideration. In the system and method, the residual capacities of the relay lines between the outgoing and incoming terminals are divided into a plurality of classes based on predetermined line capacity units, data on routes providing minimum costs in association with the classes are controlled. Boundary values of each of the classes are separately controlled at residual-line-capacity increasing and decreasing sides.
Updating operation of the route data in association with the classes takes place only when a change in the residual line capacity exceeds the capacity increasing or decreasing boundary value of the class.
