Embodiment Construction

[0039] Generally, the present invention relates to network monitoring and event management. More particularly, it relates to the processing of network metadata obtained as a result of network monitoring activities and the subsequent processing of said metadata, which can result in the reporting of useful information to event management entities in a timely manner.

[0040] In the following description, the invention is disclosed in the context of network metadata processing for illustrative purposes only. However, it should be appreciated that the present invention is suitable for a wider variety of applications and uses, and that certain embodiments of the present invention are applicable in contexts other than network metadata processing. For example, in an OpenFlow compliant environment, the system can receive NetFlow information from the network and output instructions to an OpenFlow controller.

[0041] In one embodiment of the invention, the method and system may be imp...

Abstract

An improved 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.

Description

technical field [0001] Generally, the present invention relates to network monitoring and event management. More particularly, it relates to the processing of network metadata obtained through network monitoring activities and the subsequent processing of said metadata, which can effectively result in useful information being reported to consumers of the metadata in a timely manner. Background technique [0002] Network monitoring is a critical information technology (IT) function commonly used by enterprises and service providers that involves monitoring activity occurring on internal networks to find issues related to performance, misbehaving hosts, suspicious user activity, and the like. Network monitoring is possible due to information provided by various network devices. Said information has generally been referred to as network metadata, ie, a type of information describing activity on a network that complements and complements the remaining information transmitted ov...
