The restoration of the network from failure got through different
mechanisms and algorithms at different levels of network in particular
time. Recovery methods of optical network based on GMPLS Do not take
any consideration for the integration of
communication when it establish
the backup path, which can lead to greater harm, such as the failure may
occur to a link or a path in which a large number of contacts concentrated.
Also, such concentration may leads to a negative impact in terms of the
network survivability.
