Abstract: Managing prefix lists at edge devices can include detecting, at an edge device, a traffic flow that can include a packet that specifies a destination address. The edge device can measure a bandwidth associated with the traffic flow, identify a flow bandwidth threshold defined for the edge device, and determine if the bandwidth associated with the traffic flow satisfies the flow bandwidth threshold. If a determination is made that the bandwidth associated with the traffic flow satisfies the flow bandwidth threshold, the edge device can include the destination address in a prefix list stored at the edge device. If a determination is made that the bandwidth associated with the traffic flow does not satisfy the flow bandwidth threshold, the edge device can omit the destination address from the prefix list stored at the edge device.

Abstract: Aspects of the subject disclosure may include, for example, receiving network performance metrics for a plurality of paths through a network, each path extending from a customer equipment to an application server for data communication by the customer equipment with an application running on the application server, selecting a selected path among the plurality of paths, wherein the selecting is based on the network performance metrics, and communicating between the customer equipment and the application server according to the selected path. Border gateway protocol (BGP) community values (BGP CV) add BGP performance metrics community values (BPM CV) to convey network performance metrics to provider edge routers and customer premises equipment for network selection. Other embodiments are disclosed.

Abstract: 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.
