Configuring IPv6 NetStream
Overview
IPv6 NetStream is an accounting technology that provides statistics on a per-flow basis. An IPv6 flow
is defined by the following 8-tuple elements:
•
Destination IPv6 address.
•
Source IPv6 address.
•
Destination port number.
•
Source port number.
•
Protocol number.
•
Traffic class.
•
Flow label.
•
Input or output interface.
IPv6 NetStream architecture
A typical IPv6 NetStream system includes the following elements:
•
NetStream data exporter —A device configured with IPv6 NetStream. The NDE provides the
following functions:

Classifies traffic flows by using the 8-tuple elements.

Collects data from the classified flows.

Aggregates and exports the data to the NSC.
•
NetStream collector —A program running in a Unix or Windows operating system. The NSC
parses the packets received from the NDEs, and saves the data to its database.
•
NetStream data analyzer —A network traffic analyzing tool. Based on the data in NSC, the
NDA generates reports for traffic billing, network planning, and attack detection and monitoring.
The NDA can collect data from multiple NSCs. Typically, the NDA features a Web-based system
for easy operation.
NSC and NDA are typically integrated into a NetStream server.
HPE network devices act as NDEs in the IPv6 NetStream system. This document focuses on NDE
configuration.
