Case Study: AT&T

AT&T SDN Network Design Challenge

The Mode HALO victory at the AT&T SDN Network Design Challenge further validated the operational advantage revealed by the NSF experiments. The AT&T challenge was to provide an optimal solution on a prototypical carrier network (Figure 1) in the face of rapidly rising dynamic traffic demand, with an emphasis on efficiency and cost-effectiveness. The Mode team leveraged Mode HALO to deliver a near-optimal solution in approximately thirty seconds. Mode HALO had proven unique in its ability to handle the traffic demands and scale of one of the world's largest networks in an efficient and sustainable manner.
