Multihoming with Locator/ID Separation Protocol: An Experimental Testbed

Abstract—The exponential growth of the Routing Information Base (RIB) of the Internet’s Default-Free Zone (DFZ) routers has raised concerns about non-scalability of the current Internet’s routing architecture. The main reason is that Internet addresses currently carry information about both the identity and location (physical connection point) of devices connected to the Internet. The Locator/ID Separation Protocol (LISP) has been introduced to potentially remedy this non-scalability by splitting the location and identity of devices. In this paper, we present the architecture of a deployed testbed that is multihomed using LISP. We investigate LISP performance as a multihoming solution in terms of load balancing and traffic routing in the case of link failures. I
