This project follows the instruction of UIUC ECE438 (fa21), MP2. The mp2.pdf specify the requirements. The idea is to simulate a TCP protocol with UDP, to realize reliable data transfer even when there is delay or packet loss in the network.
Author of this project: Zhongbo Zhu and Xiwei Wang.
Make sure you are in linux. You can open two virtue machines and configure the VM settings by setting their network to be host-only so that the two machines can talk to each other.
Then compile the code by make.
Then in test time, we can first configure the network card to loss packet and add network delay.
sudo tc qdisc del dev ens33 root 2>/dev/null
sudo tc qdisc add dev ens33 root handle 1:0 netem delay 20ms loss 5%
sudo tc qdisc add dev ens33 parent 1:1 handle 10: tbf rate 20Mbit burst 10mb latency 1ms
Then suppose the put lecture.mp4 in data folder, we can begin to transfer it using simulated TCP.
vm01:
./reliable_sender 192.168.10.129 5000 data/lecture.mp4 285647460
vm02:
./reliable_receiver 5000 data/recv_lecture.mp4
Here, the parameters are: IP, port, filename, bytes_to_transfer.
