The aim of the MAX project is to provide an innovative, efficient and cost-effective solution to the communication needs of heterogeneous business users distributed over large (ie metropolitan ) areas with a large concentration of information-based organisations.
The aim of the metropolitan area communication system (MAX) project is to provide a solution to the communication needs of heterogeneous business users distributed over large areas with a large concentration of information based organizations. The major objectives were the definition, design, prototype development and testing of a communication system for the flexible provision of basic and enhanced services and the support of multimegabit applications, such as local area network (LAN) to LAN linking, mainframe to mainframe communications, rapid transfer of high resolution images, and audio and video communication and conferencing. MAX is equipped with an advanced management system for configuration, fault management and user environment operation, and will use relevant existing or emerging standards.
Basic architecture and system choices have been made. Optical transmission is based on synchronous digital hierarchy (SDH), distributed multiple access protocol on distributed queue dual bus (DQDB), and open systems interconnection (OSI) consistent protocol stacks, and network management systems on telecommunication management network (TMN) principles. Compatibility is maintained with the asynchronous transfer mode (ATM) and new service standards, such as the connectionless service, whose specifications are under approval. A key element in the MAX architecture is the communication node: all nodes will have the same communication subsystem but can be equipped with different network access modules (NAM) which enable flexible interfacing and interworking with the external world. Specific NAMs will provide access, and a general purpose NAM, bursty data system (BDS), can provide modular communication protocol profiles for other commercial data applications.
The novelty of MAX can be found not only in the specific technical choices for the different subsystem but above all in the overall system features, capable of providing integrated data and video services to meet p otential demand for multiservice business networks.
The major objectives are the definition, design, prototype development and testing of a communication system for the flexible provision of basic and enhanced services and the support of multi-megabit applications, such as LAN-to-LAN linking, mainframe-to-mainframe communications, rapid transfer of high-resolution images, and audio and video communication and conferencing. MAX is equipped with basic management functions for configuration, fault management and user environment operation, and uses relevant existing or emerging standards.
The output from MAX has been the definition of the overall system and the specification, design and development of its main building blocks, with prototype development being carried out in project 5193, MAXI.
