Systems, apparatus, and methods for segment routing of optical signals

A method comprising:

• determining a first segment label that identifies a second optical packet device in an optical domain of a packet optical network;
• storing the first segment label in a forwarding table of a first packet optical device;
• sending the first segment label to a path computation engine;
• sending, by the path computation engine, the first segment label to an ingress node;
• generating a plurality of segment labels, each of the plurality of segment labels representing a respective one of a plurality of L2/L3 device between the ingress node and an egress node in the packet optical network;
• appending, by the ingress node, the plurality of segment labels and the first segment label to a packet;
• forwarding, by the ingress node, the packet to the egress node based on the plurality of segment labels and the first segment label.

A non-transitory computer-readable medium comprising instructions that, when executed by a processor, cause the processor to:

• announce a first gateway node to a packet optical network;
• announce a second gateway node to the packet optical network;
• transmit a first segment label to a path computation engine, the first segment label configured to identify the second gateway node in an optical domain of the packet optical network;
• update a forwarding table of the first gateway node with the first segment label;
• transmit the first segment label to a first packet node;
• and
• append the first segment label and a second segment label to a packet, the second segment label configured to identify the first gateway node in a packet domain of the packet optical network.
