Abstract :
PCE is an emerging technology to aggregate path computation tasks in some certain elements. The location of these elements may influence network performance. In this paper, an ILP model for PCEs location problem is formulated and a heuristic algorithm is proposed. Simulations are conducted to evaluate the effectiveness of the algorithm presented.
