Abstract:
A method for rerouting a connection earlier set up and established between a first terminal coupled to a first node (A.1.2) and a second terminal coupled to a second node (C.2), said first node and said second node being part of a switching network structured into a plurality of peer groups at at least two hierarchical levels, said earlier setup connection being set up along a path calculated between said first node (A.1.2) and said second node (C.2) comprising the steps of:determining if a failure has occurred in the earlier setup connection; andif such a failure is determined then within a peer group of said plurality of peer groups having a hierarchical level lower than the maximum of all said hierarchical levels, along said path, calculating and setting up a local alternative path within said peer group between an entering border node and an outgoing border node of said peer group along said path.
