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.
Claims20
A method comprising:
- at a controller associated with a physical layer of a network, detecting occurrence of a failure within the physical layer;
- and
- in response to detecting the failure, sending from the controller messages to at least first and second nodes in a transport layer of the network, wherein 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.
An apparatus comprising:
- an interface unit configured to connect to elements in a physical layer and a transport layer of a network;
- a processor configured to:
- detect a failure within the physical layer;
- and
- in response to detecting the failure, generate and send messages to at least first and second nodes in the transport layer of the network, wherein 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.
One or more tangible computer readable media storing logic for execution and when executed operable to:
- detect an occurrence of a failure within a physical layer of a network;
- and
- in response to detecting the failure, generate and send messages to at least first and second nodes in a transport layer of the network, wherein 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.
