How do I send a file through TCP socket?

How do I send a file through TCP socket?

Server

1. Start the program.
2. Declare the variables and structures required.
3. The socket is created using the socket function.
4. The socket is binded to the specific port.
5. Start listening for the connections.
6. Accept the connection from the client.
7. Create a new file.
8. Receives the data from the client.

What protocol do sockets use?

TCP/IP protocol
On the Internet, stream sockets are typically implemented using TCP so that applications can run across any networks using TCP/IP protocol. Raw sockets. Allow direct sending and receiving of IP packets without any protocol-specific transport layer formatting.

What is socket in TCP?

A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. Every TCP connection can be uniquely identified by its two endpoints.

Which is true for TCP connections?

TCP transmits each segment as a stream of bytes. Explanation: Data can flow both the directions at the same time during a TCP communication hence, it is full-duplex. This is the reason why TCP is used in systems that require full-duplex operation such as e-mail systems. 6.

How is communication held in a TCP socket?

Now, communication is held using input/output streams of Sockets. The InputStream of client is coupled with the OutputStream of server and OutputStream of client is coupled with the InputStream of server. Since, TCP is a two-way network protocol, hence information can flow through both the streams at the time.

How to transfer files in the network using sockets?

The basic idea is to create a server that listens on a particular port, this server will be responsible for receiving files (you can make the server sends files as well). On the other hand, the client will try to connect to the server and send a file of any type.

How to create a protocol for sending images?

The idea is simple: I designed my own protocol, where client asks server about the image, and the server sends the image, following the below steps (this is the actual protocol I wanted to implement):

How does the TCP protocol work in Python?

Doing so, each time a new client connect to the server, the accept is done by the server and the handle method of is called using the resulting socket. Moreover, using the TheadingMixIn, each client will be processed in its own thread, so you can use blocking calls and sequencial flow instead of your kind of switch.
