With the increasing number of users, enterprise networks have become more and more important, but it also faced new challenges in various aspects.Though OpenF low, the promising de facto Software defined networking(SDN) scheme which can provide finegrained and flow-level control for enterprise networks, yet it still has a few undesirable designs in credibility and scalability. Inspired by OpenF low-included many excellent studies, we have proposed a reliable and scalable architecture—Super Flow for large-scale enterprise networks in this paper. It inherits the merits of OpenF low, and overcomes OpenF lows limitations by introducing some novel features.The prototype experiment has proved that Super Flow possesses these features with desirable performance.
