A bundle-type algorithm for routing in telecommunication data networks
نویسندگان
چکیده
To optimize the quality of service through a telecommunication network, we propose an algorithm based on Lagrangian relaxation. The bundle-type dual algorithm is adapted to the present situation, where the dual function is the sum of a polyhedral function (coming from shortest paths problems) and of a smooth function (coming from the congestion).
