P2P-Based Internet-Wide Management of Interdomain Routing

Interdomain routing is the glue that holds together the disparate networks of the Internet. However, scalability constraints force individual networks to only have a local view of the Internet´s routing state. This lack of global view hinders the troubleshooting of Internet routing problems and limits the routing choices of network operators. In this paper, we propose a p2p-based infrastructure for the Internet-wide management of interdomain routing. Peers dispersed in various Internet sites collect information from the participating networks and exchange knowledge in the event of a routing problem. Thus, the infrastructure as a whole carries a global routing view. Participating networks use this infrastructure in order to obtain an insight on remote routing events and potentially respond accordingly. Our approach is novel in that it exploits the peer-to-peer paradigm for routing management purposes. The proposed infrastructure is resilient in terms of information availability, self-organizing, lightweight, and easily deployable. We illustrate the need, design, and benefits of such a management infrastructure.
