Techniques are described herein to define network programming functions for performance and liveness monitoring in Segment Routing (SR) and SRv6 networks. The network programming functions enable probe messages to run at significantly faster rates as punting probe messages to the control plane (slow path processing) and re-injecting them are not required. This enables hardware offloading for Performance Measurement (PM) sessions as well with liveness and PM probes combined. Network programming labels may be allocated from the global SR Global Block (SRGB) for SR Multiprotocol Label Switching (SR-MPLS) by a Software Defined Networking (SDN) controller. END functions are defined for SRv6 for performance delay, loss and liveness monitoring.
