In this manual, the LS81VSNP board is called LPU.2.1 Netstream Overview2.1.1 Introduction to NetstreamNetstream is a traffic statistics feature. It classifies the traffic flow through the switch intodifferent streams according to the source IP address and port number, destination IPaddress and port number, protocol number and type of service (ToS) in packets, andcollects traffic statistics about each stream independently.Figure 2-1 depicts the basic procedure of Netstream data collection and analysis.NSCNSCNDAFigure 2-1 Procedure of Netstream data collection and analysisThe procedure is as follows:1) The switch collects information about each stream and periodically sends theinformation to a Netstream collector (NSC).2) The NSC processes the information it received, and then sends the resulting datato the Netstream data analyzer (NDA).
