Abstract
In one embodiment, segment routing (SR) network processing of packets is performed which includes operations signaling and processing of packets in manners providing processing and/or memory efficiencies. One embodiment includes acquiring a segment routing particular packet by a particular router in a network. Responsive to the particular router data plane ascertained during fast path processing by a fast path processing unit that the segment routing particular packet is to be Operations, Administration, and Maintenance (OAM) processed by a different processing unit in the particular router, communicating a time stamp of a current time and the segment routing particular packet including a segment routing header that includes OAM signaling from said fast path processing to the different processing unit, with fast path processing being hardware-based packet processing by the fast path processing unit. The segment routing particular packet is OAM processing by the different processing unit.
