In this paper, we analyse the deployment of middlebox. For a given network\ninformation and policy requirements, an attempt is made to determine the\noptimal location of middlebox to achieve the best performance. In terms of\nthe end-to-end delay as a performance optimization index, a distributed middlebox\nplacement algorithm based on potential game is proposed. Through\nextensive simulations, it demonstrates that the proposed algorithm achieves\nthe near-optimal solution, and the end-to-end delay decreases significantly.
