摘要:T he Internet Architecture Board’s (IAB)’s October 2006 Routing and Addressing Workshop[8] renewed interest in the design of a scalable routing and addressing architecture for the Internet. Many concerns prompted this renewed interest, including the scalability of the routing system and the impending exhaustion of the IPv4 address space. Since the IAB workshop, several proposals have emerged that attempt to address the concerns expressed both at the workshop and in other forums[7,9,12,13,14]. All of these proposals are based on a common concept: the separation of locator and identifier in the numbering of Internet devices, often termed the “Loc/ID split.” This article focuses on one proposal for implementing this concept: the Locator/Identifier Separation Protocol (LISP)[3].
