Method of operating a communication network to provide load balancing

A method for operating a multi-segment repeater hub wherein at least some of various signal ports connecting signalling stations to the hub can be connected selectively to different segments of the hub, said method comprising:

• monitoring signal traffic between the stations and the hub and thereby establishing a database which indicates for each of a plurality of ports the volume of signal traffic between a respective one of said ports and each other port in said plurality and any segment through which any of said signal traffic flows and to which a port other than a port in said plurality is connected;
• computing the traffic to and from the ports in said plurality and said segments and the traffic between the segments for each of a plurality of possible configurations in each of which a selected port is notionally moved from connection to one segment to connection with another segment;
• computing according to selected criteria a preferred set of connections of the ports and the segments, said selected criteria including minimization of traffic between segments and substantial equalization of external traffic flows to and from each of the segments wherein computing the traffic includes:
• computing the traffic for each possible connection of a busiest port to each of the said segments to provide a plurality of candidate sets and for at least some of said candidate sets computing further candidate sets for each of a possible connection of another port to each of a plurality of the segments;
• and
• switching the connections of the ports and segments to establish said preferred set of connections.

A method for operating a multi-segment repeater hub, said method comprising:

• monitoring signal traffic between ports and between segments of the hub and maintaining a database representative thereof;
• using said database to computer possible changes to the traffic between the ports and segments for different respectively corresponding possible configurations of port-to-segment connections;
• selecting a preferred set of port-to-segment connections based on the computer possible changes;
• and
• switching the port-to-segment connections to establish said preferred set of connections.
