The ISO/OSI reference model [ISO7498] was developed by ISO, the International Standard Organization, and completed in 1982. The Open Systems Interconnection (OSI) reference model allows the connection of open systems. This objective is reached by applying a layered approach. The communication system is divided into seven layers (see Figure 13.1) [PET2000]. The lowest three layers are network dependent. They provide support for data communication between and linking of two systems. The upper three layers are application oriented. They allow the end-user application processes
to interact with each other. The intermediate layer (transport layer) isolates the application-oriented layers from the communication details at the lower layers [HAL1996].
