METHOD AND DEVICE FOR ADAPTING LABEL-SWITCHED PATHS IN PACKET NETWORKS

The invention relates to a method and a device for adapting label-switched paths, in particular MPLS paths, in packet-oriented networks which comprise routers. At least some of the routers exchange information with adjacent routers, by means of a protocol, about the status of the network, in particular about load shifts, availability changes and bandwidths, in order to recognise possible bottlenecks or improvements and, in the case of adjacent bottlenecks, locally altering paths which run through said bottlenecks, by means of partial replacement paths such that said bottlenecks are by-passed and in the case of adjacent improvements, the paths which run around said improvements are altered such as to retain said improvements in the path.
