PACKET ROUTING USING OPTICAL SUPERVISORY CHANNEL DATA FOR AN OPTICAL TRANSPORT SYSTEM
First Claim
1. A method comprising:
- receiving, by a network device that routes data traffic on a layer 3 network overlaying an optical transport system, optical supervisory channel data for an optical supervisory channel of the optical transport system;
determining, by the network device, the optical supervisory channel data indicates an event affecting transmission or detection of a signal transported by a wavelength, the wavelength traversing an optical fiber of the optical transport system and underlying a link of the layer 3 network; and
reconfiguring, by the network device in response to determining the optical supervisory channel data indicates the event, a configuration of the network device to modify routing operations of the network device with respect to the data traffic on the layer 3 network.

Abstract
In some examples, a network device comprises one or more processors operably coupled to a memory, and a routing unit configured for execution by the one or more processors to route data traffic on a layer 3 network overlaying an optical transport system; receive optical supervisory channel data for an optical supervisory channel of the optical transport system; determine the optical supervisory channel data indicates an event affecting transmission or detection of a signal transported by a wavelength, the wavelength traversing an optical fiber of the optical transport system and underlying a link of the layer 3 network; and reconfigure, in response to determining the optical supervisory channel data indicates the event, a configuration of the network device to modify routing operations of the network device with respect to the data traffic on the layer 3 network.
