Abstract
In a novel restoration management method and system, the restoration messages are treated in two ways simultaneously so as to avoid delay in transmitting to a next node. In particular, a router alert bit is attached to each restoration message at an edge of the restoration network, which is read by a Label Switched Router so as to identify the restoration message as such. Then the restoration message is duplicated. The original one is directly forwarded to the next node through the shim player so as to avoid any delay. The duplicated one is sent to the application layer at the node for being processed there.
