1. A control network for a switching system that includes a plurality of circuit-switching units interconnected by at least one communication medium, comprising:

  • a plurality of logical links, a different one of the logical links extending through the medium between each pair of adjacent ones of the plurality of units;

    a plurality of first means, one in each one of the plurality of units, the first means of an individual one of the plurality of units responsive to receipt of a message over a first link of the plurality of links extending to the individual one of the plurality of units, which message specifies a route of a circuit-switched communication through the switching system including through the individual one of the plurality of units, for establishing a communication path for the communication from an adjacent one of the plurality of units from which the first link extends, through the individual one of the plurality of units, to another adjacent one of the plurality of units which lies en-route of the communication; and

    a plurality of second means, one in each one of the plurality of units, the second means of the individual one of the individual one of the plurality of units responsive to the receipt of the message, for sending the message to the adjacent one of the plurality of units which lies en-route of the communication over a second link of the plurality of links which extends between the individual one of the plurality of units and the adjacent one of the plurality of units which lies en-route of the communication.
