Advanced Innovations in SRv6 uSID and IP Measurements - BRKSPG-3198#

Speakers: Alexey Gorovoy (NEBIUS), Pablo Camarillo (Cisco Systems, Inc.)

• Why: One of the few sessions with a real end-user architecture story (Nebius) plus hard performance numbers for a next-generation dataplane that collapses VPN, TE, and NFV into a single stateless IPv6 dataplane — directly relevant to DC/WAN interconnect and dataplane-internals interests.
• What: A status report on SRv6 uSID at claimed scale (85,000+ routers deployed across operators), a Nebius case study of a Frontend DC design that integrates VPN, TE, and NFV from front-end to peering on a single SRv6 uSID dataplane, and new IP Measurements (IPM) results: 14 million probes per second on Silicon One hardware for one-way loss, latency, and liveness. Also covers Path Tracing for per-hop visibility. (from abstract only)
• How: uSID encodes multiple micro-segments inside a single IPv6 address, letting one end-to-end header express VPN membership, traffic-engineering paths, fast reroute, and service steering without MPLS-style shim layers. IPM embeds measurement instructions in the data plane so probes follow the same path as production traffic, giving SLA measurements that correlate with actual routing.
• Where applicable: uSID requires SRv6-capable silicon and IOS-XR/Silicon One platforms; the IPM figure is tied to Silicon One hardware specifically. The Nebius frontend-DC design is operator-specific but the pattern (stateless end-to-end dataplane across DC-to-peering domains) is broadly transferable. Treat vendor-scale claims (85k routers) with the usual skepticism until verified.
