xBGP: Faster Innovation in Routing Protocols
summary
Proposes xBGP, a vendor‑neutral API plus an eBPF VM that runs BGP extension code inside existing routers, implemented in FRRouting and BIRD; demonstrates seven concrete use cases including a geolocation attribute that must be encoded, stripped before export, and touched at multiple BGP workflow insertion points; supplies a verification toolchain checking termination, memory safety, VM isolation and BGP invariants; builds and measures real routers and finds performance impact reasonable — route reflector via xBGP is <=13% overhead versus native.
