NSP Flow Collectors and Flow Collector Controllers

Description

An NSP Flow Collector is a horizontally scalable component that collects AA Cflowd or System Cflowd statistics directly from NEs. The statistics records can be forwarded to remote servers or kept in persistent storage, and are made available for processing by third-party tools or NSP Analytics.

An NSP Flow Collector Controller is required in any deployment that includes NSP Flow Collectors. A Flow Collector Controller extracts the NFM-P network data model for use as a statistics-collection framework by each Flow Collector, and updates the model as the NFM-P sends JMS notifications about model updates.

For a small-scale deployment, you can collocate an NSP Flow Collector Controller and an NSP Flow Collector on one station. A small-scale deployment has a maximum of two stations, and supports the following:

• standalone—one station that hosts a Flow Collector Controller and Flow Collector, and a second station that hosts only a Flow Collector

• redundant—two stations that each host a Flow Collector Controller and Flow Collector

Redundancy

Like other NSP components, NSP Flow Collectors and NSP Flow Collector Controllers support redundant deployment; see Description for information about NSP Flow Collector and Flow Collector Controller redundancy and other fault-tolerance mechanisms.
