Internet Research Task Force (IRTF) T. Li, Ed. Request for Comments: 6115 Cisco Systems Category: Informational February 2011 ISSN: 2070-1721 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. Status of This Memo This document is not an Internet Standards Track specification; it is published for informational purposes.
