destination address, source IP address, destination port number, source port

As shown in Figure
follows:
1 The device configured with NetStream periodically delivers the statistics collected
to NetStream collector (NSC).
2 The NSC processes the statistics and then sends the results to NetStream data
analyzer (NDA).
3 The NDA analyzes the statistics for accounting, network layout, and the like. The
NDA can analyze the output statistics through XLog.
