Abstract

Efforts are now underway to develop protocols for Inter-Administrative Domain Routing. Such protocols will allow each Administrative Domain (AD) in the growing Internet (and internets in general) to independently express and enforce policies regarding the flow of packets to, from, and through its resources. This paper articulates the requirements for policy based routing and should be used as input to the functional specification and evaluation of proposed protocols.

Two critical assumptions will shape the type of routing mechanism devised: (1) the topological organization of ADs, and (2) the type of policies that need to be enforced. After justifying our assumptions regarding AD topology we present a taxonomy, and specific examples, of policies that must be supported by an inter-AD routing protocol. We use the Research Internet as our central example because of its size and scope.
