NetStream Top Talkers

NetStream Top Talkers

A typical NetStream system consists of three roles: NetStream data exporter (NDE), NetStream collector (NSC), and NetStream data analyzer (NDA). The NSC and NDA are configured on a NetStream server. The NDE with NetStream configured periodically sends traffic statistics to the NetStream server, and the NetStream server analyzes the statistics and shows statistics reports for you to monitor network traffic in real time. If a NetStream server is not located on a network or if traffic statistics cannot be exported to the network where a NetStream server resides due to customers' security requirements, the NetStream Top Talkers function can be configured to allow customers to monitor the network running status in real time.

NetStream Top Talkers filters traffic based on user-defined keywords, collects statistics on filtered traffic, sorts the traffic in a certain order, and displays only the top N traffic lines on screen. N is the number of traffic lines recorded in the NetStream Top Talkers template, and these N traffic lines are called Top Talkers.

NetStream Top Talkers can filter traffic according to the following keywords: source port number, destination port number, source IP address, destination IP address, next-hop IP address, source Autonomous System (AS), destination AS, packet priority, protocol type, number of packets, and number of bytes.

NetStream Top Talkers sorts traffic in either of the following orders:
  • Descending order of bytes: The Top Talker with the most bytes is listed on the top line.
  • Descending order of packets: The Top Talker with the most packets is listed on the top line.
