Abstract: Embodiments disclosed include a method and apparatus for global traffic control and optimization for software-defined networks. In an embodiment, data traffic is optimized by distributing predefined metrics (data traffic information) to all controllers in the network. The predefined metrics are specific to local network switches and controllers, but are distributed to all peers at configurable intervals. “Local” as used herein implies one POP and its associated switch and controller. The method of distribution of local POP metrics is strictly in band using a packet as defined by the protocol used by the data network.

Abstract: Some embodiments of the invention provide a method for defining a telecommunications network deployment for a particular geographic region comprised of a set of sub-regions, the telecommunications network including an access network, an edge network and a core network. For each UE of multiple UEs distributed across the particular geographic region, the method selects a traffic category from a set of traffic categories to associate with the UE, and based on the selected traffic category, the method uses an application traffic model to compute an upper threshold limit of an attainable data rate for the UE. For each link of multiple transport links that connect the multiple UEs to the telecommunications network, the method determines a link capacity for each transport link based on the upper threshold limits of the attainable data rates computed for each UE of the multiple UEs.
