SRv6-6G

Segment Routing over IPv6 with Compute Telemetry

An advanced source-routing protocol encoding network paths, compute instructions, and slicing tags directly into IPv6 packet header extensions.

Technical Explanation

Traditional transport networks required complex signaling protocols (like MPLS, LDP, and RSVP-TE) to maintain path state in every intermediate router. SRv6 encodes the entire desired path into an IPv6 Segment Routing Header (SRH) at the ingress node. In 6G, SRv6-6G extends this by encoding compute instructions directly into the header—instructing intermediate routers to execute AI model inference or route to specific GPU clusters along the path.

Key Functions

  • Source-routing encoding complete end-to-end paths directly inside IPv6 extension headers
  • Eliminating complex MPLS and stateful protocol overhead across intermediate transport routers
  • Encoding compute instructions (Service Function Chaining) directly into packet headers
  • Native multi-domain network slicing across enterprise, transport, and cellular domains
  • Hardware-accelerated line-rate segment processing in modern P4 and ASIC switching silicon
