A study of locator ID Separation Protocol.

摘要

Locator ID/Separation Protocol (LISP) aims at solving the issues in the current Internet Routing Architecture. The growth of the BGP routing table and Forwarding Information bases on core routers is very high. In addition, the number of BGP messages that are currently being processed by the BGP routers is a worrisome issue. Locator/ID Separation Protocol (LISP) is a recently proposed approach that provides a solution to these problems. By employing LISP, it is anticipated that significant scaling benefits can be achieved among which are the reduction of routing table sizes, traffic engineering capabilities, mobility without address changing. We present an analysis of how much these improvements are. Furthermore, a detailed study of this protocol is carried out and is compared against other solutions that are proposed along with an analysis of LISP as well.
