Patent ID: 7506050

Claim:
A method for checking, by a resource manager in an automatic process, transmission resources of a packet-oriented communication network upon a topology change, comprising: checking reservation of the transmission resources based on topology data relating to network topology of the packet-oriented communication network; analyzing topology change information generated as a result of the topology change of the network topology and received by the resource manager; temporarily switching to a static resource reservation mode, by the resource manager, upon receiving the topology change information indicating an inconsistency between a topology image stored in the resource manager and the network topology; transferring a localization specification with the topology change information to specify an area of the packet-oriented communication network affected by the topology change; rejecting, by the resource manager in the static resource reservation mode, resource requests that affect the area specified by the localization specification, regardless of the resource reservation of the transmission resources; and processing, by the resource manager in the static resource reservation mode, resource requests that do not affect the area specified by the localization specification based on the reservation of transmission resources present before the topology change.
