#python-udp-filetransfer

This was an networking assignment. The idea was to create a server and client, where the client could download files from the server. Files are transferred over UDP, but packet retransmission is added. You can also force random packet drops too.

server.py

Usage: python server.py port p_err

Where

  • port is the port number to listen on
  • p_err is the probability of a packet being deliberately dropped by the server, where 0 <= p_err <= 1

The server is blocking, so it will run, display the its IP address, and await a packet from the client. Output is printed for each packet sent and received.

client.py

Usage: python client.py srcfile destfile addr port p_err

Where

  • srcfile is the file to download from the server
  • destfile is the file to save the downloaded file as locally
  • addr is the address of the server
  • port is the port to send data to the server on
  • p_err is the probability of a packet being deliberately dropped by the client, where 0 <= p_err <= 1

The client will send a request to the server, which will initiate communication between the two. As with the server, the client prints output for each packet sent and received.
