Abstract
Techniques are provided for detecting at a controller associated with a physical layer of a network an occurrence of a failure within the physical layer of the network. In response to detecting the failure, the controller sends messages to at least first and second nodes in a transport layer of the network, where the messages are configured to indicate normal operations in the physical layer so as to prevent execution of transport layer protection processes for a period of time.
