Multihoming with locator/ID Separation Protocol: An experimental testbed

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.
