File Transfer using Socket Programming (TCP and UDP)

The idea is to provide a basic understanding of socket programming in python and analyzing the throughput achieved by differnet types of implementations. I have implemented variants of file transfer in terms of concurrency and algorithms. These variants are listed as follows:

  1. Based on type of connection:
    • TCP
    • UDP
  2. Based on Algorithms:
    • Nagle’s Algorithm
    • Delayed ACK
  3. Based on Concurrency:
    • concurrent server using Fork
    • concurrent server using threads
  4. Based on Consistency:
    • Persistent TCP connection
    • Non-persistent TCP connection

Novels

Serial number Novel Name File named as at server side Size (MB)
1. Sherlock Holmes sherlock.txt 3.9
2. War and Peace warpeace.txt 3.4
3. Jane Eyre janeeyre.txt 3.2
4. Middlemarch middlemarch.txt 1.8
5. Romeo and Juliet romeo.txt 1.5

TCP usage

  1. Analyzing the algorithms

    • move into the folder tcp_algorithms
    • run server using python3 server.py and enter the port number
    • run client in another terminal using python3 client.py
    • enter the port number of the server
    • follow the instructions to enable or disable the algorithms
    • user can ask for only one file at a time

  2. Concurrency - fork

    • move into the folder tcp_fork
    • run the server using python3 fork_server.py
    • run client in another terminal using python3 fork_client.py
    • ask the files in spave separated fashion like sherlock.txt warpeace.txt
    • the client side will connect with the server individually for each file (running the all the clients simultaneously)

  3. Concurrency - threads

    • move into the folder tcp_thread
    • run the server using python3 thread_server.py
    • run client in another terminal using python3 thread_client.py
    • ask the files in spave separated fashion like sherlock.txt warpeace.txt
    • the client side will connect with the server individually for each file (running the all the clients simultaneously)

  4. Non persistent TCP

    • move into the folder tcp_non_persistent
    • run the server using python3 nonp_server.py
    • run client in another terminal using python3 nonp_client.py
    • ask the files in spave separated fashion like sherlock.txt warpeace.txt
    • one by one file transfer (each creating a new tcp connection)

UDP usage

In UDP, persistent and non-persistent remains same because there is no particular handshake in UDP which initiates the connection.
