GB/T 15274-1994 Internal organization of the network layer of information processing systems Open Systems Interconnection

This standard provides an architectural model of the OSI network layer as a framework for standardization of the OSI network layer to enable existing networks to be incorporated into the OSI architecture. The framework encourages the design of real subnetworks that fully support OSI network services, while also accommodating the inclusion of other subnetworks that do not fully support OSI network services into the OSI environment. This standard is intended for use in the design and application of network layer protocols that operate between network entities either in end systems that provide OSI network services or in intermediate systems that provide routing and interruption functions. This standard should be used to: a. provide a common set of concepts and terminology used in network layer standards (which should reference this standard); b. analyze the functionality of the network layer and classify network layer protocols; c. specify how "real networks" should be used to support or provide OSI network services, especially when multiple "real networks" are to be interconnected and used. The organizational structure defined here does not address network layer management, and in particular does not address the relationships between network layer entities that may be required for network layer management purposes. In addition, this standard does not specify the operational requirements for relay functions within intermediate systems, nor does it address how specific combinations of allowed functions can be effectively and practically utilized.
