TCP-Client-Server-Application

Implement a TCP client- server application to implement a service that returns the sounds made by animals. The name of each requested animal will be specified by a client . The server will start in passive mode listening on a specified port for a transmission from a client. Separately, the client will be started and will contact the server on a given IP address and port number that must be entered via the command line.

If the server is subsequently restarted, it reverts to knowing only about the initial 3 pairs.

For communication with server client has to register itself with server.

The server, which will be called SoundServer, will operate as follows:

Return the sound made by animals named by a client after the client connects to the server using the SOUND instruction,
Accepts a STORE message used for storing new (animal, sound) pairs,
Accepts a QUERY message used to ask which animals it knows,
Accepts a BYE message that results in closing of the current session between the client and the server.
Accepts an END message that results in closing of the current session and termination of the server.

Use the following messages to communicate with server :

register - To register with server
login - To communicate with server (if client is already registered)
sound - To confirm that connection has established
store - To store new animal-voice pair
query - To get names of all stored animals
bye - To instruct server that client no longer needs this session
end - To instruct server to shut down
animal name - To get voice of given animal

Client: SOUND

Server: SOUND: OK

To get the voice of given animal

Client: DOG

Server: A DOG SAYS WOOF

If client enters name of animal that is not stored in server's memory

Client: CAT

Server: I DON’T KNOW CAT

To store a new animal-voice pair

Client: STORE

SERVER: STORE: OK

To get names of all animals stored in server's memory

Client: QUERY
