Abstract:

A new addressing and routing design called the Less-Is-More Architecture
(LIMA) is proposed as an interdomain solution for a future Internet.
Unlike recently proposed locator-identifier split solutions, LIMA uses
just (topological) location-independent names and location-dependent
addresses. The feasibility of using a policy combination of restricting
stubs to provider-aggregatable addressing only, and disallowing stub-level
reachability from being propagated into the global routing tables, is
studied. This policy combination results in significantly smaller global
routing tables but creates four challenges of address renumbering (when
stubs change providers), multihoming, mobility, and traffic engineering.
Solutions to these challenges are based on the use of multiaddressing,
name based sockets, a LIMA concept of address dismemberment, transport
protocols such as SCTP that are capable of dynamic address
reconfiguration, and new management-plane and control-plane procedures.
Preliminary RIB data analysis quantify the benefit of LIMA in global
routing table size reduction (to 6815 entries from today?s 335K entries),
and a cost of LIMA in terms of number of provider changes made by stubs in
the last six months (about 2450 provider changes per month across 33K
stubs).
