Abstract: In one embodiment, segment routing (SR) network processing of packets is performed which includes operations signalling and processing of packets in manners providing processing and/or memory efficiencies. One embodiment includes receiving a particular segment routing 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 based on an Operations, Administration, and Maintenance (OAM) segment identifier of the particular segment routing packet that the particular segment routing packet is to be OAM processed by a different processing unit in the particular router, communicating the particular segment routing packet to the different processing unit, with fast path processing being hardware-based packet processing by the fast path processing unit. The particular segment routing packet is OAM processing by the different processing unit.

Abstract: In one embodiment, a node in a communication network receives a label switched path (LSP) request and in response, the node determines at least two equal cost paths, each path having one or more path-nodes. The node may then further determine a total bandwidth-based transition value for each path of the at least two equal cost paths and selects the path having a lower total transition value. Once selected, the node may establish the requested LSP over the selected path.
