Foreword This Technical Report (TR) has been produced by ETSI Special Committee User Group. Introduction Local Area Networks (LANs) were developed following the adv
13、ent of the desktop computer (or personal computer), in response to desktop computer users need to have access to more services and resources than could be provided by a single stand alone computer (mainframe computer users already had star networks for connection of their desktop terminals to the ho
14、st computer). These services and resources were initially contained within a small area, e.g. an office, a factory, or a single building. It soon became apparent that users also needed to have access to other LANs either in different locations within their own company or within other companies. Conn
15、ection to remote networks was first made possible by using quite unwieldy dial-up methods soon followed by the advent of LAN interconnection either via a high speed data link within the same site or Metropolitan Area or via a Wide Area Network (WAN) to more distant locations anywhere in the world. T
16、herefore a series of LAN interconnect devices were developed to address various interconnection tasks. There are four basic types of LAN interconnection devices: - repeaters; - bridges; - routers: and - gateways. A set of definitions are provided in subclause 3.1, with further information in annex B
17、. These definitions follow the Open System Interconnection (OSI) Reference Model developed by the International Standards Organization (ISO), i.e. device types are defined by the OS1 layer(s) at which the interconnection function is performed. A definition of the OS1 Reference Model is given in anne
