Design and implementation of a routing control platform

摘要: The routers in an Autonomous System (AS) must distribute the information they learn about how to reach external destinations. Unfortunately, today's internal Border Gateway Protocol (iBGP) architectures have serious problems: a "full mesh" iBGP configuration does not scale large networks and "route reflection" can introduce problems such as protocol oscillations persistent loops. Instead, we argue that Routing Control Platform (RCP) should collect destinations topology select BGP routes for each router AS. RCP is logically-centralized platform, separate from IP forwarding plane, performs route selection on behalf of communicates selected using unmodified protocol. provides scalability without sacrificing correctness. In this paper, present design implementation prototype commodity hardware. Using traces routing data Tier-1 backbone, demonstrate fast reliable enough drive decisions network. We show assigns correctly, even when functionality replicated distributed, expect comparable convergence delays those architectures.
