7.3 Data Plane
7.3.1 Introduction to the Data Plane
NSPs are key parts on the NE20E and are responsible for network processing and data
exchange between PICs and NSPs.
The procedure for data processing is as follows:
1.
The IP packets sent from PICs and NSP converge at a convergence module.
2.
The NP processes the IP packets.
3.
The TM module performs traffic management on the IP packets.
