摘要
Facebook continues to see hyper-exponential and unpredictable growth for both machine-to-machine and machine-to-user traffic. Achieving high service availability in an economical way is a massive design and optimization challenge for planning Facebook's large scale backbone network. The multilayer planning algorithm developed for this study at Aria Networks, models the IP and optical layer together, explores solutions beyond shortest paths, and scales to solve a topology with 100+ sites, and 200+ links. Based on topology and traffic data from the Facebook production network, we demonstrate savings in excess of 25% for the total cost of ownership of the network, using a multilayer design with high priority services protected in IP/MPLS layer and low priority services restored in the optical layer.
