Network Link Layer (NL2)

The Network Link Layer (NL2) software component provides real-time applications with abstract APIs to access network services at Layer 2 of the OSI model, independent of the underlying hardware. This typically includes:

• Transmit and receive raw Ethernet packets
• Configure and get the link status
• Configure hardware timestamping
• Configure hardware filters
• Configure QoS

Using the NL2, you can easily integrate network functionality such as TCP/IP, EtherCAT, PTP (Precision Time Protocol), and TSN (Time Sensitive Networking).
