In order to solve the multi-controller placement problem of Software Defined Networking (SDN), this paper proposes a collaborative approach based on a competitive game. Under the premise of constraining the local network load, the gain setting of a single competitive game collaborative selects the participants of the next round of the game, and after applying the collaborative approach several times, the total networks latency is effectively reduced and load balancing is obtained. The simulation results in Internet2 OS3E topology and Cernet topology show that the proposed approach is more stable in terms of networks latency index and effectively ensures the balanced distribution of network load compared with the multi-controller placement schemes derived from K-means clustering, K-means++ clustering, and K-medoids clustering.
