Abstract

There is ongoing work positioning Segment Routing version 6 (SRv6) as a replacement to General Packet Radio Service (GPRS) Tunneling Protocol User Plane (GTP-U). The main benefits of using SRv6 include coupling of the mobility overlay with the underlay (transport Traffic Engineering (TE)) and service chaining (GiLAN) and reusing high performance routers with SRv6 capabilities as User Plane Functions (UPFs). Techniques are described herein for enabling the creation of specific network slices where in the underlay a high resiliency is achieved with zero packet loss for tight Service Level Agreement (SLA) enterprise premium traffic. This same mechanism may be reused for path monitoring (e.g., latency, jitter, etc.) using in-band mechanisms for Ultra-Reliable Low Latency Communications (URLLC).
