Oct 15, 2015 · The "client" and "server" program contains some dubious code. First lets take the "server", which calls sendto with clientaddr which you haven't initialized. Who knows where you try to send the packets. This, in fact, leads to undefined behavior, as the contents of the structure is indeterminate.
client.c implements a reliable data transfer client over UDP in C. Both of these programs use the go-back-n ARQ, that is lost data is. automatically resent. These programs are hardcoded to transfer. to compile: gcc -o server server.c. gcc -o client client.c. */. #include <sys/types.h>.
STOP AND WAIT PROTOCOL implementation in C: The Stop-and-Wait protocol is a simple flow control mechanism used in communication networks, particularly in telecommunications and computer networks. It is a half-duplex protocol that ensures reliable delivery of data by transmitting a data frame and waiting for an acknowledgement (ACK) message from ...
1. The algorithm I considered is as follows. 1) sender sends data using sendto (). 2) waits for ACK packet from the receiver. 3-1) sends the same packet if ACK for the next packet hasn't arrived within timeout. 3-2) sends the next one if ACK for the next packet arrived. Just the same way as a normal algorithm.
Nov 9, 2017 at 23:16. yes. so initally we were using send () as reliable. The next phase is to replace send () with packetErrorSend () which drops packets at random and so we have to handle the loss of packets with select statements. The only hint that was given is if the client times out, resend the last packet.
Jun 18, 2021 · I have a client and server code that is working fine with a single input string. I was trying to change the code for file transfer but no success. Can anyone help me with minimal changes to convert the below code for using file transfer? code of client.c. #include <stdio.h>. #include <stdlib.h>. #include <string.h>. #include <unistd.h>.
