TCP THE TRANSMISSION CONTROL PROTOCOL (TCP) ADDS THE GUARANTEE OF RELIABLE, ORDERED DELIVERY OF DATA. TCP IS IMPLEMENTED USING IP (i.e. TCP PACKETS GET STUFFED INSIDE IP PACKETS ). RELIABILITY IS PROVIDED BY SENDING ALL MESSAGES "RETURN RECEIPT REQUIRED". EACH MESSAGE IS ASSIGNED A "SERIAL" NUMBER. RECEIVER MUST SEND AN "ACKNOWLEDGEMENT" INCLUDING THE SERIAL NUMBER FOR EACH MESSAGE RECEIVED. SENDER TRIES AGAIN IF ACKNOWLEDGEMENT DOESN'T ARRIVE "IN TIME".
