This letter studies the problem of optimizing the decision latency for software-defined networking (SDN) structured by multiple controllers. According to the mode of processing non-local tasks in SDN, we propose a novel model for this multi-controller structure, which generalizes the traditional flat and hierarchical structures. We formulate the decision location problem (DLP) to optimize the decision latency based on this model. It is shown that the DLP in the flow initialization can be reformulated as a 0-1 integer optimization problem, which we use a heuristic genetic algorithm to solve. The numerical evaluation verifies the effectiveness of the proposed method.
