The IESG has received a request from an individual submitter to consider the following document: - 'Asymmetric Extended Route Optimization (AERO)' <draft-templin-aero-10.txt> as an 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 2012-04-18. 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 Nodes attached to common multi-access link types (e.g., multicast- capable, shared media, non-broadcast multiple access (NBMA), etc.) can exchange packets as neighbors on the link, but may not always be provisioned with sufficient routing information for optimal neighbor selection. Such nodes should therefore be able to discover a trusted intermediate router on the link that provides both forwarding services to reach off-link destinations and redirection services to inform the node of an on-link neighbor that is closer to the final destination. This redirection can provide a useful route optimization, since the triangular path from the ingress link neighbor, to the intermediate router, and finally to the egress link neighbor may be considerably longer than the direct path from ingress to egress. However, ordinary redirection may lead to operational issues on certain link types and/or in certain deployment scenarios. This document therefore introduces an Asymmetric Extended Route Optimization (AERO) capability that addresses the issues. The file can be obtained via http://datatracker.ietf.org/doc/draft-templin-aero/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-templin-aero/ballot/ No IPR declarations have been submitted directly on this I-D.
