Sending and receiving messages with UDP

Premise: To send messages from client —> host —> server, and back again. The client is to encode a message into a byte array and start the interaction, where the host and the server are waiting to receive. The server decodes the received message, determines if it is read or write, and sends the appropriate reply.

Client: It begins the interaction and sends messages out first, then receives Host: Acts as an intermediate between the Client and Server. Receives first, and then sends out Server: Where “logic” is performed. Receives a message first, decodes it, then sends a reply back to the host to send to the client
