Abstract
In one embodiment, an optical network includes a plurality of converged IP and optical routers and a plurality of optical links interconnecting the plurality of converged IP and optical routers. The optical network further includes a network controller configured to broadcast a link quality metric (LQM) to the plurality of converged IP and optical routers. The LQM defines a link quality associated with each optical link of the plurality of optical links, wherein data traffic mapping is performed by the plurality of converged IP and optical routers using the broadcast LQM.
Claims20
An optical network, comprising:
- a plurality of converged IP and optical routers;
- a plurality of optical links interconnecting the plurality of converged IP and optical routers;
- and
- a network controller configured to broadcast a link quality metric (LQM) to the plurality of converged IP and optical routers, wherein the LQM defines a link quality associated with each optical link of the plurality of optical links, wherein data traffic mapping is performed by the plurality of converged IP and optical routers using the broadcast LQM.
A method for network traffic control, the method comprising:
- calculating, by a processor, a link quality metric (LQM) for each optical link of a plurality of optical links interconnecting a plurality of converged IP and optical routers;
- broadcasting the LQM to the plurality of converged IP and optical routers to cause the plurality of converged IP and optical routers to perform data traffic mapping using the broadcast LQM;
- and
- transmitting data traffic via the plurality of optical links based using the data traffic mapping.
A system for controlling data traffic, comprising:
- a plurality of processors;
- and
- a non-transitory computer-readable storage medium storing instructions which, when executed by the plurality of processors, cause the plurality of processors to:
- calculate a link quality metric (LQM) for each optical link of a plurality of optical links interconnecting a plurality of converged IP and optical routers;
- broadcast the LQM to the plurality of converged IP and optical routers to cause the plurality of converged IP and optical routers to perform data traffic mapping using the broadcast LQM;
- and
- transmit data traffic via the plurality of optical links based on the LQM.
