COMMUNICATIONS NETWORK MANAGEMENT
First Claim
1. A communications network, the communications network being partitioned into a plurality of network segments, each of the plurality of the network segments comprising a segment management module, a plurality of network elements and a plurality of communications links, the plurality of network elements being interconnected by the plurality of communications links, the network being configured such that, in operation:
- i) each of the segment management modules receives operational data from the plurality of network elements in its respective network segment;
ii) on the basis of operational data received from the plurality of network elements, each segment management module determines the future performance of the plurality of network elements in the respective network segment;
iii) if a segment management module determines that the future performance of one or more of the plurality of network elements in the respective network segment will be less than a threshold value, re-routing one or more data flows, to a further segment; and
iv) reconfiguring one or more of the segments carrying the one or more data flows.

Abstract
The present invention provides a segmented network in which each segment comprises one or more routers, one or more communications links to provide connectivity between the router(s) and a segment management module. The segment management module uses operational data to predict the future performance of each element. If the predicted performance will breach a threshold value then a data flow may be re-routed. Re-routing between different segments can lead to network management problems and so the present invention discloses methods by which: segments can expand to acquire a router from another segment; segments can subdivide; and segments can merge together, particularly if a segment comprises too few routers.
