+1. Receive UDP packet
+2. Modify received packet
+ a.exchange src mac and destination mac
+ b.exchange src ip and destination IP for both IPv4 and IPv6 cases
+ c.exchange UDP src port and UDP destination port
+ d.change the len of the response according to the IMIX definition (
+ option to make traffic more realistic to emulate some IoT payloads)
+3. send modified packet to the port where it was received.
+
+Such VNF does not need LPM and routing table implementations.
+As the packet modification is very minimal and there is no memory access as the packet is stored in L3 cache the
+performance of the solution should be sufficient for testing the UDP NAT performance.
