Internet Engineering Task Force (IETF) R. Asati Request for Comments: 6201 C. Pignataro Updates: 1242, 2544 F. Calabria Category: Informational Cisco ISSN: 2070-1721 C. Olvera Consulintel March 2011 Device Reset Characterization Abstract An operational forwarding device may need to be restarted (automatically or manually) for a variety of reasons, an event called a "reset" in this document. Since there may be an interruption in the forwarding operation during a reset, it is useful to know how long a device takes to resume the forwarding operation. This document specifies a methodology for characterizing reset (and reset time) during benchmarking of forwarding devices and provides clarity and consistency in reset test procedures beyond what is specified in RFC 2544. Therefore, it updates RFC 2544. This document also defines the benchmarking term "reset time" and, only in this, updates RFC 1242. Status of This Memo This document is not an Internet Standards Track specification; it is published for informational purposes. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG).

Introduction An operational forwarding device (or one of its components) may need to be restarted for a variety of reasons, an event called a "reset" in this document. Since there may be an interruption in the forwarding operation during a reset, it is useful to know how long a device takes to resume the forwarding operation. In other words, the duration of the recovery time following the reset (see Section 1.2, "Reset Time") is what is in question.Show full document text
