42 Network Feature | Korenix
As the figure bellow, the traffic handled by the JetBox9500 moves through the fast-path alone
without any CPU intervention.
This fast-path can receive packets, perform rule look ups, determine the ip address to which
the packet should be routed to, and transmit the packet out using hardware engines. Packets
that cannot be processed by fast-path routed to the CPU/control-path. As a result, higher
level stack services such as HTTP, DHCP, etc. can still be provided via the CPU path while still
maintaining throughput performance consistently using the fast-path.
NOTE

The fast-path database is limit to 16 rules (connections).

Both source and destination address MUST be reachable;
otherwise fastpath can
’t learn their MAC address.
