摘要： Systems and processes for filtering network traffic. In one example, an event based flow record aging process may be used to identify flow records to be removed from memory to provide space for newer flow records. In this example, a new incoming network packet may trigger a determination of the flow record to be removed from memory based on the hardware time stamps of the flow records stored in memory. Determining aging flow records in this way may advantageously reduce the amount of computer resources required to manage flow record aging when compared to traditional techniques that require keeping a timer and periodically performing a cleanup process to check the freshness date of each flow record.
摘要翻译：过滤网络流量的系统和流程。在一个示例中，基于事件的流记录老化过程可用于识别要从存储器移除以提供较新流程记录的空间的流记录。在该示例中，新的传入网络分组可以基于存储在存储器中的流记录的硬件时间戳来触发要从存储器移除的流记录的确定。与需要保持定时器并周期性地进行清理处理以检查每个流记录的新鲜度的传统技术相比，以这种方式确定老化流记录可有利地减少管理流记录老化所需的计算机资源量。

摘要： A method includes configuring a plurality of rate filters for a plurality of protocols. The plurality of rate filters are associated with a plurality of rate thresholds for the plurality of protocols. An edge device receives a packet for a flow. The packet is received from a customer premise equipment device for sending through an egress interface of the edge device. A rate of packets being sent for the flow and a protocol in the plurality of protocols associated with the packet are determined. A rate filter in the plurality of rate filters that is associated with the determined protocol is determined where the rate filter is associated with a rate threshold in the plurality of rate thresholds. The method determines an event is occurring when the rate of packets exceeds the rate threshold associated with the determined rate filter and performs an action to mitigate the event.

摘要： Methods, systems, and computer readable media for enhanced service detection and policy rule determination are disclosed. According to one method, a policy charging and rules function (PCRF) node requests, from a deep packet inspection (DPI) node notification of detection of traffic relating to a service. The DPI node identifies at least one traffic classifier usable to detect traffic corresponding to the service, uses the traffic classifier to detect traffic corresponding to the service, and notifies the PCRF of the detection and of the traffic classifier. The PCRF node receives the at least one traffic classifier, determines a policy rule based on the at least one traffic classifier, and communicates the policy rule to a policy enforcement node.
