Could you please help me with an algorithm for selective repeat protocol file transferring good documentation?Is there any book for protocol programming just like Beej guide for Network Socket Programming?
You could try the TCP RFCs I believe this one is the one you want.
You could also pick up a textbook on networking: Computer Network: A Top Down Approach is a pretty good one (I've taken a few networking courses and that's been the best one thus far).
Also, google is your friend!
