messages triggered by intradomain changes varies significantly across time and router locations. We show that hot-potato routing changes lead to longer delays in forwarding-plane convergence, shifts in the flow of traffic to neighboring domains, extra externally-visible BGP update messages

in forwarding-plane convergence, (iii) OSPF-triggered BGP updates have a nearly uniform distribution across destination prefixes, and (iv) the fraction of BGP messages triggered by OSPF varies significantly across time and router locations, with important implications on external monitoring of BGP. Our

enforcement, and security. In this article, we argue that one of the principal reasons for this is the way control and forwarding planes are interspersed in IP networks today. We review the architectural developments that led to the current situation, and we reason that centralization of network control

that this lattice filling curve converges in the diffusive scaling limit to a plane filling curve which is the boundary between the forward and backward Brownian webs. A one-dimensional projection of the two-dimensional result proves the convergence of Tóth’s self-repelling walk to the Tóth-Werner continuum self

We demonstrate a prototype system of functionally distributed transport networking (FDTN) architecture that separates the control-plane processing part (control element, CE) from the forwarding-plane processing part (forwarding element, FE) of a router. In an FDTN, one path-control process

. We also demonstrate significant impacts on the data plane: blackholes sometimes last throughout the route-convergence process, and forwarding changes, at best, are only polynomially less frequent than routing changes. We show that these problems vanish in contiguous regions of the Internet

logicallycentralized platform, separate from the IP forwarding plane, that performs route selection on behalf of routers and communicates selected routes to the routers using the unmodified iBGP protocol. RCP provides scalability without sacrificing correctness. In this paper, we present the design and implementation

establishes terminology to standardize the description of benchmarking methodology for measuring eBGP convergence in the control plane of a single BGP device. Future documents will address iBGP convergence, the initiation of forwarding based on converged control plane information and multiple interacting BGP
