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 clases are controlled, and one of routes corresponding to the class satisfying the request line capacity of the outgoing terminal is selected to thereby realize the dandem connection between the outgoing and incoming terminals.
