Query: Controlling a Software-Defined Network via Distributed Controllers   In this paper, we propose a distributed OpenFlow controller and an associated
coordination framework that achieves scalability and reliability even under
heavy data center loads. The proposed framework, which is designed to work with
all existing OpenFlow controllers with minimal or no required changes, provides
support for dynamic addition and removal of controllers to the cluster without
any interruption to the network operation. We demonstrate performance results
of the proposed framework implemented over an experimental testbed that uses
controllers running Beacon.
