An Efficient Approach to Map Identity onto Locator

摘要

Today's Internet routing and addressing system is facing serious scaling problems. Once IPv6 is widely deployed, and in the absence of a scalable routing strategy, the routing scalability problem today can potentially be exacerbated by IPv6's much larger address space. Identity/locator separation scheme is being discussed as an efficient approach to solve the scalability issues. This paper proposes a candidate of the identity /locator separation schemes, and provides a corresponding mapping service. The key design concepts include separating customer networks from the core network strictly, decoupling node identities from their network locations, and bridging customer networks and the core network by a mapping service. The separating scheme can provide efficient improvements in routing scalability, while the mapping scheme is of great benefits to mobility, and multihoming. At the end of the paper, we give some evaluations.
