Communicate between two systems using only MAC address

I want to know how to communicate between two systems using only MAC address using C program (without using IP address). I think this is raw ethernet communication. My requirement is to send data from client to server only by using the MAC address. May be this can be done by crea开发者_如何学JAVAting our own raw ethernet frame.

Please help me regarding this. If anybody has written code in C, please share.

The libpcap library allows you to assemble raw Ethernet packets and send them directly to an adapter: the hardest part being the discovery of the correct adapter. This is designed for C/C++ usage on most platforms (Win PCAP etc.).

Be sure this is what you want though: I have seen several projects where raw Ethernet packet interfaces have been used, only for more and more protocol to be put in place for re-transmission and windowing etc. until you end up with your own version of TCP/IP (only one that hasn't been tested by millions of people using Windows/Linux or whatever your platform is). Most Ethernet chips have functions to accelerate TCP/IP stacks these days too: so you will be missing out on that too.

Here are examples for C#, maybe you can leverage this. The right code depends on OS and even from the used chips when programming for microcontrollers.
