For example, the aggregation mode configured on the NDE is protocol-port, which means to aggregate
statistics of 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 different
source addresses. According to the aggregation mode, only one NetStream aggregation flow is created
and sent to the NetStream server.
Table 4 lists the 12 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.
