Multithreaded-chatroom

Architecture of the program:

Connection:

When the server started:

Thread starts to accept connections from the clients

Client side when it starts connection:

Input: ip port number and username(which is limited to 16)

Server side: accept the connection add new user to the user list and broadcast the new user arrived.

Process When new connection arrives it gets added to the connection list and , that list is broadcasted amongst the existing users It then gets hashed with the dictionary datatype variable hasha . Hasha hashes all the Ip address with the connection socket object.

When the clients send chats:

Client side: send a chat (if it’s more than 154 length it will not fit in the header format so not accepted)

Server side: thread reads the input and broadcast it to the users.

Every once in a while:

Server side : send everyone about the existing users.

When the clients leave the chats:

Client side: quit the chat by closing Server side: Send every users about one users’ leaving
