Everyone must follow these rules, because if not, the program we want to communicate with wouldn’t understand us, or in the worst case, misunderstand us. - -For our network, we’ve decided to build upon the Post Office Protocol (POP) version 3. It follows the request-response model, is synchronous, and meets our requirements. - -An example of a request and response (for our game) might look like this: - -1. Request - ```text - GET_DELTA 42 - ``` - -2. Response - ```text - +OK - PLAYER_FOLDED playerId=3 - POT 240 - NEXT_TURN playerId=1 - WHISPER from=player2 msg="hey" - CHAT_LOBBY player3="hello" - . - ``` - -The client requests the occurred actions since the 42nd state. - -The server responds with all the actions other players have made and the messages the client has received. -
