6.6.1 Specifying a NetStream Service Processing Mode

After performing packet sampling, each NetStream-enabled LPU sends sampled packets to the
NetStream service processing board for aggregation and output. If the NE5000E has more than
one NetStream service processing board, these NetStream services boards work in redundancy
mode for service backup and load balancing, which improves system reliability.
Context
NetStream services can be processed in either of the following modes:

Distributed mode
In this mode, a single LPU can perform NetStream functions independently, including
packet sampling, flow aggregation, and flow output.
Integrated mode
In this mode, the LPU only samples packets and sends sampled packets to the NetStream
service processing board. Flow aggregation and flow output are performed on the
NetStream service processing board. If the data volume collected by the router is beyond
