1. Developed Virtualized network function foor NAT functionality using minios based vms called clickos.
2. Clickos image provides a NFV framework built on C++ for packet processing functions.
3. Wrote application for NAT and deployed it on a separate VM.
4. I made use of xen hypervisor & open vswitch to connect other similar VNFs together.
5. Using Ovsdb commands, configured flowrules to steer the packet through all the VMS to attain service chaining.
