LISP-DHT: Towards a DHT to map identifiers onto locators

Sat, 11/29/2008 - 00:03 by Damien Saucez • Categories:


Recent activities in the IRTF (Internet Research Task Force),
and in particular in the Routing Research Group (RRG), fo-
cus on defining a new Internet architecture, in order to solve
scalability issues related to interdomain routing. The re-
search community has agreed that the separation of the end-
systems' addressing space (the identifiers) and the routing
locators' space will alleviate the routing burden of the De-
fault Free Zone. Nevertheless, such approach, adding a new
level of indirection, implies the need of storing and distribut-
ing mappings between identifiers and routing locators. In
this paper we present LISP-DHT, a mapping distribution sys-
tem based on Distributed Hash Tables (DHTs). LISP-DHT
is designed to take full advantage of the DHT architecture in
order to build an efficient and secured mapping lookup sys-
tem while preserving the locality of the mapping. The paper
describes the overall architecture of LISP-DHT, explaining
its main points and how it works.
