Instructions to Run 🏃

• To run the TCP server, go to the tcp folder and run the command python3 tcp_server.py

• To run the TCP client, go to the tcp folder and run the command python3 tcp_client.py. This will give the user options to send specific files. Those files can be selected and send.

• The same instructions goes for the UDP client and UDP server.

• To disable nagle's algorithm in TCP server uncomment line 21

• in tcp_sever.py.

• To disable nagle's algorithm in TCP client uncomment line 29 in tcp_client.py.

• To disable delayed ACK in TCP server uncomment line 24 in tcp_server.py

• To disable delayed ACK in TCP client uncomment line 32 in tcp_client.py

• Buffersize can be changed in clients and servers of both tcp and udp, by changing the global variable BUFSIZE.

• To add sleep of 100 us in TCP server uncomment line 48 in tcp_server.py

• To add sleep of 100 us in UDP server uncomment line 29 in udp_server.py
