Abstract
A packet optical network may include a packet optical gateway node that is configured to advertise a segment label to other nodes in the network where the segment label is used by a source node in place of a conventional segment routing label when the source node generates the list of labels included in the header of a data packet while establishing a path through a network. The segment label differs from a conventional segment routing label in that the segment label indicates the L0/L1 device or path as opposed to the L2/L3 device indicated by a conventional segment routing label.
