Abstract:
Most ISPs and Autonomous Systems on the Internet today use Open Shortest Path First (OSPF) or Intermediate- System-to-Intermediate-System (IS-IS) as the Interior Gateway Protocol (IGP). Both protocols are Link-State routing protocols and require distribution of link state information to all routers. Topological changes require redistributing updates and refreshing routing tables, resulting in high convergence times. Routing table sizes grow linearly with network size, indicating scalability issues. Future Internet initiatives provide new venues to address the routing problem. In this article, a Tiered Routing Protocol (TRP) is presented as a candidate protocol for intra-AS routing. TRP is supported by a tiered addressing scheme. TRP replaces both IP and the routing protocol. TRP’s performance is compared with OSPF using Emulab test-beds.
