The IESG has received a request from an individual submitter to consider the following document: - 'The Intradomain Routing Overlay Network (IRON)' <draft-templin-ironbis-12.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2013-02-18. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract Since large-scale Internetworks such as the public Internet must continue to support escalating growth due to increasing demand, it is clear that Autonomous Systems (ASes) must avoid injecting excessive de-aggregated prefixes into the interdomain routing system and instead mitigate de-aggregation internally. This document proposes an Intradomain Routing Overlay Network (IRON) architecture that supports sustainable growth within interior routing domains while requiring no changes to end systems and no changes to the exterior routing system. In addition to routing scaling, IRON further addresses other important issues including mobility management, mobile networks, multihoming, traffic engineering, NAT traversal and security. While business considerations are an important determining factor for widespread adoption, they are out of scope for this document.
