Abstract
In an example embodiment, a method of route convergence is provided. In this method, a loss of connectivity is detected along a communication route by way of an Ethernet Operations, Administration, and Maintenance (OAM) protocol. Examples of Ethernet OAM protocols include Connectivity Fault Management protocol and Ethernet Local Management Interface protocol. Thereafter, a data link layer identifier associated with the communication route is identified and this data link layer identifier is mapped to a network layer address. Convergence on an alternate communication route can then be based on the mapped network layer address.
Claims22
A method comprising:
- detecting a loss of connectivity along a communication route by way of an Ethernet Operations, Administration, and Maintenance (OAM) protocol;
- identifying a data link layer identifier associated with the communication route;
- mapping the data link layer identifier to a network layer address;
- and
- converging on an alternate communication route based on the network layer address.
Logic encoded in one or more tangible media for execution and when executed operable to:
- detect a loss of connectivity along a communication route by way of an Ethernet Operations, Administration, and Maintenance (OAM) protocol;
- identify a data link layer identifier associated with the communication route;
- map the data link layer identifier to a network layer address;
- and
- converge on an alternate communication route based on the network layer address.
An apparatus comprising:
- at least one processor;
- and
- a machine-readable medium in communication with the at least one processor, the machine-readable medium being configured to store a fault detection module, the fault detection module being executed by the at least one processor cause operations to be performed, comprising:
- detecting a loss of connectivity along a communication route by way of an Ethernet Operations, Administration, and Maintenance (OAM) protocol;
- identifying a data link layer identifier associated with the communication route;
- mapping the data link layer identifier to a network layer address;
- and
- converging on an alternate communication route based on the network layer address.
An apparatus comprising:
- a first means for detecting a loss of connectivity along a communication route by way of an Ethernet Operations, Administration, and Maintenance (OAM) protocol;
- a fault detection module to identify a data link layer identifier associated with the communication route;
- a second means for mapping the data link layer identifier to a network layer address;
- and
- the fault detection module to converge on an alternate communication route based on the network layer address.
