-/* Changes for Correlated traffic VNF
-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.
