Enhanced MILSA Architecture for Naming, Addressing, Routing and Security Issues in the Next Generation Internet

MILSA (Mobility and Multihoming supporting Identifier Locator Split Architecture) [1] has been proposed to address the naming and addressing challenges for NGI (Next Generation Internet). we present several design enhancements for MILSA which include a hybrid architectural design that combines “core-edge separation approach” and “split approach”, a security-enabled and logically oriented hierarchical identifier system, a three-level identifier resolution system, a new hierarchical code based design for locator structure, cooperative mechanisms among the three planes in MILSA model to assist mapping and routing, and an integrated MILSA service model. The underlying design rationale is also discussed along with the design descriptions. Further analysis addressing the IRTF (Internet Research Task Force) RRG (Routing Research Group) design goals [9] shows that the enhanced MILSA provides comprehensive benefits in routing scalability, traffic engineering, mobility and multihoming, renumbering, security, and deployability.
