"NIRA: A New Internet Routing Architecture "
Xiaowei Yang, MIT

Abstract:

In this talk, I will present the design and evaluation of a new Internet
routing architecture (NIRA). The present Internet routing system suffers
from two problems: one structural and one architectural. The structural
problem is that the current system has little support for users to
choose domain-level routes. User choice plays an important role in
creating market competition, which fosters innovation and the
introduction of new services. The architectural problem is that the
current system fails to scale effectively in the presence of real-world
requirements such as multi-homing. NIRA is a scalable architecture that
gives a user the ability to choose domain-level routes. The design of
NIRA addresses four problems: how routes are discovered and selected,
how routes are efficiently represented, how route failures are detected,
and how providers are compensated. NIRA augments a strict
provider-rooted addressing hierarchy with a new topology distribution
and address allocation capability to enable scalable route discovery and
efficient route representation. It combines proactive notification and
reactive discovery for fast failure detection. NIRA's provider
compensation model is still contract-based. The evaluation of NIRA
suggests that it is practical.
