API design and implementation of a management interface for SDN whitebox switches

Abstract

For the past few years, cloud computing has emerged to be one of the most rapidly growing plaforms. This growth must be supported from the data centers, that look to provide the best possible service, while minimising energy and infrastructure costs. As such, many service providers are moving to Software Defined Networking (SDN) based platforms, that allow for new concepts such as the separation of the control and data planes, and the adoption of open source material, in both the switches, in the form of whitebox switches, and the network controllers. BISDN is a company that is developing a SDN controller, that allows to use the linux networking tools, like netlink, to configure and manage ports on switches. The proposed problem, is then extending the existing platform to be able to report statistics such as flow-counts on the switches, the number of packets received, dropped, transmitted in the ports, so that the data center operators can have the best possible information on the state of their network, and act in case of failures and malfunctions.
