This paper proposes an architecture for inter-domain routing, called DTIA - Dynamic Topological Information Architecture. DTIA separates the issues of reachability and routing, and this paper addresses the first one. One major requirement has been not to change IP packets and the commercial relations in the Internet. DTIA is based on the knowledge of a static network formed by the Autonomous Systems (AS) and an algorithm to manage link failures. We use the concept of a region as a mechanism to sustain scale. DTIA supports the most important functionalities of BGP: some of them are built in and others can be implemented on top of the reachability level or the routing level. The main concerns we aim to solve are taking advantage of multihoming, increase the robustness in terms of convergence, reduce the churn rate and range of routing events, and due to forwarding packets by AS identifiers and topologic links (as opposed to prefix policy defined) reduce the growth of the routing table.
