I'm trying to simulate a TCP protocol while using UDP. I want my server to be able to send chunks of the file the client requested while waiting for acks from the client.
My idea is to send chunk then recv (listen for ack) but that makes it so I can only send chunk nº2 after receiving ack nº1. Should I just send all of them in a loop and then wait for all the acks in a loop with timeouts? Or is there way to have recv in the background with a timeout and if it receives an ack it stops the setsockopt timeout feature, and if the timeout occurs it interrupts the current script to resend that chunk? Edit: My bad didn't mention it was using C. OS is linux.
