摘要： The present invention relates to systems and methods for detecting anomalies in computer network traffic with fewer false positives and without the need for time-consuming and unreliable historical baselines. Upon detection, traffic anomalies can be processed to determine valuable network insights, including health of interfaces, devices and network services, as well as to provide timely alerts in the event of attack.

摘要： A method and system for processing network metadata is described. Network metadata may be processed by dynamically instantiated executable software modules which make policy-based decisions about the character of the network metadata and about presentation of the network metadata to consumers of the information carried by the network metadata. The network metadata may be type classified and each subclass within a type may be mapped to a definition by a unique fingerprint value. The fingerprint value may be used for matching the network metadata subclasses against relevant policies and transformation rules. For template-based network metadata such as NetFlow v9, an embodiment of the invention can constantly monitor network traffic for unknown templates, capture template definitions, and informs administrators about templates for which custom policies and conversion rules do not exist. Conversion modules can efficiently convert selected types and/or subclasses of network metadata into alternative metadata formats.
摘要翻译：描述了一种用于处理网络元数据的方法和系统。可以通过动态实例化的可执行软件模块来处理网络元数据，所述可执行软件模块对网络元数据的特征进行基于策略的决定，以及关于由网络元数据携带的信息向网络元数据呈现给消费者。网络元数据可以是类型分类的，并且类型中的每个子类可以通过唯一的指纹值映射到定义。指纹值可用于将网络元数据子类与相关策略和转换规则进行匹配。对于基于模板的网络元数据（如NetFlow v9），本发明的实施例可以不间断地监视未知模板的网络流量，捕获模板定义，并且向管理员通知关于哪些自定义策略和转换规则不存在的模板。转换模块可以有效地将网络元数据的选定类型和/或子类转换为替代元数据格式。
