I reviewed this document as part of the Security Directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the Security Area Directors. Document authors, document editors, and WG chairs should treat these comments just like any other IETF Last Call comments. This Informational draft outlines methodology for benchmarking switches, carried out on isolated test networks. It defines no new protocols or device capabilities in support of the recommended methodology, or anything else which would introduce any new security considerations.
