Recommendation for a Routing Architecture
Abstract
It is commonly recognized that the Internet routing and addressing
architecture is facing challenges in scalability, multihoming, and
inter-domain traffic engineering. This document presents, as a
recommendation of future directions for the IETF, solutions that
could aid the future scalability of the Internet. To this end, this
document surveys many of the proposals that were brought forward for
discussion in this activity, as well as some of the subsequent
analysis and the architectural recommendation of the chairs. This
document is a product of the Routing Research Group.
