Systematically testing OpenFlow controller applications

Jennifer Rexford, Dejan Kostic, Marco Canini, Maciej Leszek Kuzniar, Peter Peresini

The emergence of OpenFlow-capable switches enables exciting new network functionality, at the risk of programming errors that make communication less reliable. The centralized programming model, where a single controller program manages the network, seems ...
