Abstract
A network management system in a communications network comprises a managed object base having a plurality of managed objects describing individual resources of the network; a detection means for detecting changes for configuration of the network; a route finding means for generating data describing a set of routes of trails across said network, and a trail manipulation means for implementing changes to trails across the network. The trail manipulation means operates in four basic modes of operation, including a stretch operation in which a new node is inserted between first and second existing nodes and an existing trail between the first and second existing node is rerouted by the new node by creation of a pair of new links; Firstly, a stretch operation in which a new node is inserted between first and second existing nodes and an existing trail between the first and second existing node is re-routed via the new node by creation of a pair of new links. Secondly, a split operation in which a single trail extending between first and second nodes over at least one intermediate node is split into a plurality of trails. Thirdly, a shrink operation in which a trail extending between fi…
