SamSamhuns / TCP_implementation

TCP simplified implementation with congestion control and congestion avoidance.

TCP implementation

project2-Teona-Sam

Project II (Task I): Transmission Control Protocol (TCP) This TCP implementation uses congestion control and ss Threshold to model the transmission control that happens in TCP over internet connections.

Sample Congestion window graph.

Requirements

mininet VM. Can be built from source or a pre-built Mininet VM can be downloaded at http://mininet.org/download/.

How to Build

Use the make file in the src directory to build the executable files.

mininet@mininet-vm:~$ make

Run mininet

Start the mininet servers ith different parameters for bandwidth, delay and loss proportions.

sudo mn --link tc,bw=10,delay=10ms,loss=2

mininet> xterm h1 h2

Two terminal will popup for h1 and h2; Run sender and receiver on these two terminal

Terminal node h1:

rdt_receiver <Port num i.e. 60001> <rcv_file_name>

Terminal node h2:

rdt_sender 10.0.0.1  <Same Port num as receiver i.e. 60001> <send_file_name.bin>

Verify the two files are the same and generate a congestion window graph

The Grapher.py script uses the CND.csv file generated by the rdt_sender file.

cksum <rcv_file_name> <send_file_name.bin>
python3 Grapher.py
