NetStream aggregation data export
NetStream aggregation merges the flow statistics according to the aggregation criteria of an
aggregation mode, and it sends the summarized data to the NetStream server. This process is the
NetStream aggregation data export, which uses less bandwidth than traditional data export.
For example, the aggregation mode configured on the NDE is protocol-port, which means that is
aggregates statistics about flow entries by protocol number, source port, and destination port. Four
NetStream entries record four TCP flows with the same destination address, source port, and destination
port, but with different source addresses. In the aggregation mode, only one NetStream aggregation
flow is created and sent to the NetStream server.
Table 4 lists the 1
2 aggregation modes. In each mode, the system merges flows into one aggregation
flow if the aggregation criteria are of the same value. These 12 aggregation modes work independently
and can be configured on the same interface.
