Claim 10:
11. A method comprising:
accessing, by a fast path processing unit, a memory storing a packet comprising one or more packet headers, wherein at least one of the one or more headers comprises segment routing information, the segment routing information including at least Operations, Administration, and Maintenance (OAM) information, the OAM information including at least OAM signaling information;
acquiring, by the fast path processing unit of a routing node, OAM information associated with the packet;
responsive to the OAM signaling information in the segment routing information, transferring the OAM information and processing of the packet to a slow path processing unit of the routing node;
applying, by the slow path processing unit, one or more OAM processing operations on the packet, wherein:
the fast path packet processing unit performing hardware-based packet processing; and
the slow path packet processing unit performing processor-based packet processing based on programmed instructions.
