Abstract: A device may include one or more memories, and one or more processors to receive a plurality of packets over a network. Packets, of the plurality of packets, may relate to a subscriber. The subscriber may be a source subscriber from which the packets are initiated or a destination subscriber to which the packets are destined. The device may determine whether a rate of receipt of the packets satisfies a first threshold, detect whether a level of processor usage satisfies a second threshold, and perform one or more actions to cause filtering of additional packets relating to the subscriber based on whether the rate of receipt of the packets satisfies the first threshold and based on whether the level of processor usage satisfies the second threshold. The device may monitor filtering of the additional packets to determine whether to filter further packets relating to the subscriber.

Abstract: A system may include one or more devices to receive a flow record. The one or more devices may identify a type of the flow record. The one or more devices may parse the flow record for a template identifier (ID) if the type of the flow record is a data record. The one or more devices may further compare the template ID from the data record to a predetermined template ID identifying a data record of template IDs. The one or more devices may identify the data record as a data record of template IDs if the template ID matches the predetermined template ID. The one or more devices may further generate a map associating template IDs, from the data record of template IDs, to template information for decoding and/or interpreting data records. The one or more devices may store the map.
