The IESG has approved the following document: - 'Mechanisms for Optimizing LAG/ECMP Component Link Utilization in Networks' (draft-ietf-opsawg-large-flow-load-balancing-15.txt) as Informational RFC This document is the product of the Operations and Management Area Working Group. The IESG contact persons are Benoit Claise and Joel Jaeggli. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-opsawg-large-flow-load-balancing/ Technical Summary This draft explores some mechanisms useful for achieving optimal use of bandwidth in wired networks that make extensive use of LAG/ECMP techniques for bandwidth scaling. Working Group Summary There was no major drama in the WG related to this document. Document Quality The document is well written and easy to follow. A number of authors indicated that their employers are implementing, or have plans to implement this. There was some discussion at adoption time regarding if implementation advice is appropriate work for the WG. Consensus was on the side of adoption. There was also (primarily off-list) discussion that implementations should expose per-interface queue length. This information would make the technique in the draft more useful and could allow one to avoid placing traffic on interfaces that have long queues for some reason. While this would make the technique better, interface counters provide sufficient information to make the technique useful. Personnel Warren Kumari is the Document Shepherd. Benoit Claise is the Responsible Area Director.
