Embodiment Construction

[0025] In this article, a "network application" is a management function that runs outside of networking equipment but uses network service information and statistics to manage network infrastructure and / or provide network-based data services. Applications use "flow-based statistics" to obtain information about certain types of traffic moving across the network in addition to the actual type of traffic, so the meaning of "flow" is application-dependent.

[0026] The actual need for flow-based statistics from a particular point of view varies widely among network applications. In order to minimize the amount of output data without reducing the possible applications, the application message level must be added at the node level. The present invention proposes to include an "application session management" layer within the flow monitoring system.

[0027] An "application session" represents the current set of flow statistics requirements of a process connected to the flow monito...

Abstract

A flow monitoring system for obtaining flow-based statistics in a communications network is described. An application session management (ASM) function is incorporated into the system to allow flow-based statistics to be customized in relation to network applications. This is accomplished by having the ASM interface with the usual flow monitoring functionality and network applications to collect and process flow statistics, and to customize exported data to match application requirements.

Description

technical field [0001] The invention relates to service flow monitoring in a communication network, in particular to a system and method for collecting flow statistics of network applications. Background technique [0002] Flow-based statistics use information extracted from packet headers to classify network traffic and can provide a higher level of traffic visibility than interface-based packet counts. These statistics are becoming an important tool to help effectively manage routing networks and deploy advanced network services. [0003] Network applications that benefit from flow-based statistics include usage-based billing, service-level agreement (SLA) monitoring, traffic engineering, traffic configuration, network security systems, and network troubleshooting. Among these applications, billing and SLA monitoring are end-to-end network services that are only used at the edge of the network, but others can be used at all network locations, including access, edge and co...
