Abstract:

Proper functioning of routing protocols is essential to the operation of the Internet, but current routing protocols are vulnerable to both accidental failures and malicious attacks. We present the Internet Routing Validation (IRV) architecture, which the routing entities of the Internet can use to help detect and mitigate accidentally or maliciously introduced faulty routing information. The architecture uses information collected from routing-policy databases, routing announcements, and configuration tables, and network monitoring facilities; it can provide both corroborative evidence that received routing announcements are valid, and act as a warning system when it senses departures from the expected or allowed state of affairs. The IRV architecture can be adopted incrementally by each Internet service provider, and does not require global adoption before its users can reap its benefits. In this talk, we present the ongoing research in the IRV architecture, and discuss plans for future work.
