ABSTRACT:
A control network for allocating resources (i.e. making routing decisions) in an associated telecommunications network is disclosed. Illustratively, the control network comprises a group of processors arranged in a ring. A database containing information about the exact state of the telecommunications network circulates in a ring-like control network. When an originating switching office in the telecommuncations network wishes to set-up a connection, it seizes one of the processors in the control network and informs it of the desired connection. The processor runs a call set-up algorithm utilizing the database and makes a routing decision which is communicated back to the originating switching office. The originating central office then physically sets up the call in the telecommunications network.
