Python UDP

Created for a networking course, this is an example of a simple UDP application in Python 3 consisting of a sender, channel and a receiver.

This was written to an assignment specification however I don't seem to have a copy of the assignment PDF anymore.

How to run

You'll need 3 command prompts or terminal windows each running one Python file

1. Run the channel.py as follows;

• Usage: python3 channel.py <csin_port> <csout_port> <crin_port> <crout_port> <sin_port> <rout_port> <drop_rate> <hash>
• Example: python3 channel.py 5006 5005 5007 5008 5004 5001 0.01 somehash

2. Run the receiver.py as follows;

• Usage: python3 receiver.py <rin_port> <rout_port> <crin_port> <file_to_receive>
• Example: python3 receiver.py 5001 5002 5007 testOut.dat

3. Run the sender.py as follows;

• Usage: python3 sender.py <sin_port> <sout_port> <csin_port> <file_to_send>
• Example: python3 sender.py 5004 5003 5006 file.dat

The parameter names aren't exactly the most descriptive but try matching up the port numbers to see who is talking to who.
