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.
Claims22
A method of collecting flow statistics at a network node in a communications network comprising:
- providing an application session management (ASM) function to interface with the network applications, the ASM collecting information about the actual flow statistics needs of the applications;
- and
- maintaining individual session information for each application.
A method of collecting flow statistics at a network node in a communications network comprising:
- providing an application session management (ASM) function to interface with an embedded flow monitoring subsystem at the node, the ASM affecting the operation of the flow monitoring subsystem such that the embedded resources are used to best monitor the traffic flows specified by the network applications;
- and means for managing the node flow monitoring subsystem as application needs change.
A method of collecting flow statistics at a network node in a communications network comprising:
- providing an application session management (ASM) function to receive the traffic flow counters from the embedded flow monitoring subsystem and use this data to generate statistics in accordance with the needs of the network applications;
- and means for exporting the generated statistics in a manner specified by the application during session initialization.
