PURPOSE: A structure of a common protocol layer for transmitting data between heterogeneous protocols, a method for the same, and a common protocol packet are provided to perform a mutual communication operation without a converting process between existing protocol layers by inserting a common layer into an upper part or a lower part of an application layer. CONSTITUTION: A structure of a common protocol layer for transmitting data between heterogeneous protocols includes an application layer, a common protocol layer, an expression layer, a session layer, a transport layer, a network layer, a data link layer, and a physical layer. The application layer(10) is used for providing a service function to perform a communication operation between plural systems and defining a data construction. The common protocol layer(20) is used for performing an address mapping operation, an address converting operation, a segmentation operation, and a reassembly operation to switch each protocol. The expression layer(30) is used for converting one expression type of input or output data to the other expression type. The session layer(40) is used for performing a setup process for transmitting and receiving a message between end host programs, controlling a data synchronization process, and forming a communication session. The transport layer(50) is used for managing control operations and errors. The network layer(60) is used for controlling a data path to transmit correctly a packet to a receiver. The data link layer(70) is used for controlling an error of a physical level and providing a synchronization process and identifying and managing a state of transmission. The physical layer(80) is used for transmitting a bit stream and providing a hardware for transmitting and receiving the data through a transmission medium.
