Wiederherstellung eines Netzwerkes

摘要

A method of restoring an active path (P1) between two nodes (SN1, SN4) of a transport network (SDH) upon occurrence of a failure (F) includes the steps of determining an alternate path (P2) through the network (SDH) and establishing a path protection (1 + 1 SNCP) involving the failed active path (P1) and the alternate path (P2). If in layered networks, a failed path is restored at a lower layer and at a higher layer concurrently, the restoration actions in the higher network layer can thus be reverted easily.
