As required by most Service Provider (SP) network operators, ISSU functionality has been implemented by modern forwarding devices to upgrade or downgrade from one software version to another with a goal of eliminating the downtime of the router and/or the outage of service. However, it is noted that while most operators desire complete elimination of downtime, minimization of downtime and service degradation is often the expectation.

     Benchmarking Methodology for In-Service Software Upgrade (ISSU)


   Modern forwarding devices attempt to minimize any control- and data-    plane disruptions while performing planned software changes by    implementing a technique commonly known as In-Service Software    Upgrade (ISSU).  This document specifies a set of common    methodologies and procedures designed to characterize the overall    behavior of a Device Under Test (DUT), subject to an ISSU event.
