Address-based Route Reflection
by Ruichuan Chen 13 Jan '12

13 Jan '12

Dear all, The document below may be of interest: "Address-based Route Reflection" at http://bgp.mpi-sws.org/papers/abrr-CoNEXT11.pdf by Ruichuan Chen (MPI-SWS), Aman Shaikh (AT&T Labs Research), Jia Wang (AT&T Labs Research), Paul Francis (MPI-SWS) ==== Abstract ==== This work presents Address-Based Route Reflection (ABRR): the first iBGP solution that completely solves all oscillation and looping problems, has no path inefficiencies, and puts no constraints on RR placement. ABRR does this by emulating the semantics of full-mesh iBGP, and thereby adopting the correctness and path efficiency properties of full-mesh iBGP. Both traditional Topology-Based Route Reflection (TBRR) and ABRR take a divide-and-conquer approach. While TBRR scales by making each RR responsible for all prefixes from some fraction of routers, ABRR scales by making each RR responsible for some fraction of prefixes from all routers. Best regards, --Ruichuan
