Patent ID: 10419152

Abstract:
An apparatus that includes one or more electrical or optical I/O ports that interface to external communication equipment, one or more optical ports that interface to an optical transport network that carries wavelength-division-multiplexed (WDM) optical signals, one or more tunable optical transceivers, and packet switching logic. The apparatus is configured to perform packet processing operations for ingress and egress data frames or packets. The apparatus can further include control circuitry that can take part in an automatic provisioning process that configures the tunable optical transceiver units of the network device, specifically configuring the optical channels/wavelengths of the optical signals that are transmitted by the tunable optical transceivers. The apparatus can also implement a method of processing and/or managing the optical channels/wavelengths of the optical signals that are transmitted by the tunable optical transceivers based upon the destination address of ingress data frames or packets. Multiple units can interface to the optical transport network for communication of optical packet data between the units over the optical transport network as described herein.
