Hi all, I'm working on a UDP File(large) transfer application. Client end is Adobe Flash builder and also in VC++ and Server end is C++. I'm sending my file in packets and resending the missing packets.Finally it is taking the time what ever TCP. I'm using winsock2 at server end but not complete functions.Is there any better protocols or approaches which can help me. I'm in the mid of the project. Can anybody suggest me so that I can get the wanted result.
