2.4 Data Plane
2.4.1 Introduction to the Data Plane
NPUs are key parts on the CX600-X2-M8 and are responsible for network processing and data
exchange between PICs and NPU-50s.
The procedure for data processing is as follows:
1.
The IP packets sent from PICs and NPU converge at a convergence module.
2.
The NP processes the IP packets.
3.
The TM module performs traffic management on the IP packets.
