DESCRIPTION:Dry run for PAM.\n\nRecent efforts in software-defined networ
 ks\, such as OpenFlow\, give unprecedented access into the forwarding plan
 e of networking equipment. When building a network based on OpenFlow howev
 er\, one must take into account the performance characteristics of particu
 lar OpenFlow switch implementations. In this paper\, we present OFLOPS\, a
 n open and generic software framework that permits the development of test
 s for OpenFlow-enabled switches\, that measure the capabilities and bottle
 necks between the forwarding engine of the switch and the remote control a
 pplication. OFLOPS combines hardware instrumentation with an extensible so
 ftware framework.\n\nWe use OFLOPS to evaluate current OpenFlow switch imp
 lementations and make the following observations: (i) The switching perfor
 mance of flows depends on applied actions and firmware. (ii) Current Ope
 nFlow implementations differ substantially in flow updating rates as well
  as traffic monitoring capabilities. (iii) Accurate OpenFlow command comp
 letion can be observed only through the data plane. These observations are
  crucial for understanding the applicability of OpenFlow in the context of
  specific use-cases\, which have requirements in terms of forwarding tabl
 e consistency\, flow setup latency\, flow space granularity\, packet mod
 ification types\, and/or traffic monitoring abilities.\n
