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.
