Abstract
A distributed control exchange according to the present invention is provided with a plurality of sections for executing, in the form of a distributed process, a call process for a call occurred at an individual line. When a call has occurred at a certain line, one of these sections that executes a call process relating to that line also executes, based on a result of routing, a call process relating to a line to become a destination party. Therefore, the distributed control exchange according to the invention can reduce the resources that are used for cooperation of the plurality of sections and enables stable load distribution. Further, the distributed control exchange realizes cost reduction and improvement of reliability.
