Query about Networking Based C program

Is it possible to Build a C Program to perform the sending of a file through Connectionless Packet Switching in LINUX Platform through SOCKET BINDING. What I mean by this is that each host should have a routing table of its own and when a file is to be sent from one host to another host and if there is no point to point connection between these 2 hosts, the sending host should forward this file to an intermediate node(s) which has the shortest route between these 2 hosts. It would be very helpful if someone can let me know whether this is possible and also share their experience on this. Thank You

Is this going to sit on top of TCP/IP? Since you said connectionless, I'm thinking UDP packets containing the file data. Can you elaborate on your plan some more? What exactly is going in the custom routing table? It almost sounds like you want to write your own routing software.

Or a rudimentary proxy host....

The routing table basically consists of the path from a source to destination like for example, if 3 nodes are there and node 1 can send to node 3 only through node 2, then the routing table of node 1 will have 2 Column entries called DESTINATION NODE and NEXT NODE where if the destination node contains node 3 for the routing table of node 1, then using the NEXT NODE entry( node 2 in this case), the file should be forwarded to node 2 which then sends it to node 3.

Now that the question is understood...
Yes it's possible...

Since it sounds like you don't know much at all about socket programming, I suggest you start with Beej's Guide to Network Programming. Google around for more tutorials and examples. Get a handle on basic TCP and UDP connections first. Start with simple examples and build up to your routing thing.
