Performance Evaluation of OpenFlow Scheduled Bundles for Consistent Updates

Abstract

In this paper, we implemented OpenFlow scheduled bundle in the Open vSwitch software switch and evaluated its performance in SDN testbed networks under different scenarios. The scheduled bundle is a very new mechanism proposed in the OpenFlow protocol for achieving consistent updates among multiple SDN switches. However, this feature has not been supported in any hardware SDN switches or any software SDN switches such as the very popular Open vSwitch software switch. As a result, no results about the performance and effectiveness of scheduled bundle have been reported in the literature. In this work, we implemented scheduled bundle in Open vSwitch, which is the first implementation of scheduled bundle in the world, and evaluated its performance and effectiveness under various scenarios.
