Each ANIC adapter has a very powerful and flexible L2/L3/L4 packet parser. The header information from each packet that enters the system is extracted and processed to inform the host application about relevant packet details and also as input for packet filtering.
Tunneling and Encapsulation
The parser is able to recognize various tunneling and encapsulation protocols such as VLAN, VXLAN, MPLS, GTP and GRE. The adapter is then able to intelligently strip away the tunnel encapsulations and analyze the relevant packet information contained inside the tunnel.
