A processing system may obtain a first sampled flow record for a first flow in a network, comprising information regarding selected packets of the first flow, derive, from the first sampled flow record, a data volume and a duration of the first flow, and determine a first flow metric for the first flow that is calculated from the data volume and the duration, where the first flow metric is one of a plurality of flow metrics for a plurality of flows, and where the plurality of flow metrics is determined from the plurality of sampled flow records associated with the plurality of flows. The processing system may then classify the first flow into one of at least two classes, based upon the first flow metric and at least a first flow metric threshold.

A system for closed loop prefix management for white boxes includes a network device, a route reflector coupled to the network device, a software defined network controller coupled to the route reflector and the network device, and a prefix usage analyzer in the software defined network controller. The prefix usage analyzer determines usage attributes of prefixes and identifies the prefixes with a predetermined usage attribute. The software defined network controller instructs a network controller in the network device to store the prefixes with the predetermined usage attributes in a table in the network device.

Closed loop prefix management and controller for whiteboxes

A system for network device measurements may use a white box to perform measurements that may help determine the likelihood of network anomalies, such as microbursts.

A software-defined network multi-layer controller (SDN-MLC) may communicate with multiple layers of a telecommunication network. The SDN-MLC may have an optimization algorithm that helps in capacity planning of the telecommunications based on the management of multiple layers of the telecommunication network.
