Scalable ID-Based Communication

The philosophy behind the ID and locator separation is that an identity must be used for denoting a communication entity and must be independent from the topological location of the entity. While the ID and locator separation provides a sound solution to mobility and handling topology changes, which cannot be solved inherently by the current Internet, its benefits are overshadowed by the routing scalability since the IDs cannot be aggregated. Unlike the traditional Internet that deals with the scalability issue at the address- level by aggregating IP addresses in the headers of the IP packets, we solve the scalability issues by structuring the network with hierarchically organized domains. In this paper, we present a highly scalable ID-based communication scheme, ID based route computation, and ID based forwarding under the framework of our architecture, ID-based networking Architecture (IDNet).
