Abstract
In a restoration network including a distributed restoration algorithm (DRA) enabled network of a telecommunications network, path verification messages are embedded onto traffic bearing signals entering the network and removed from the signals leaving the network. By adding path verification messages to the signals that traverse within the DRA enabled network, the integrity of any communications path that interconnects the various nodes within the restoration network are confirmed. Further, by removing the path verification messages from the signals leaving the restoration network, equipment outside the restoration network are spared of any possibility that their operations may be affected by the path verification messages.
