2.1 Netstream Overview

2.1.1 Introduction to Netstream

Netstream is a traffic statistics feature. It classifies the traffic flow through the switch into
different streams according to the source IP address and port number, destination IP
address and port number, protocol number and type of service (ToS) in packets, and
collects traffic statistics about each stream independently.

Figure 2-1 Procedure of Netstream data collection and analysis
The procedure is as follows:
1) The switch collects information about each stream and periodically sends the
information to a Netstream collector (NSC).
2) The NSC processes the information it received, and then sends the resulting data
to the Netstream data analyzer (NDA).
