一简介几年前由于高速传输数据和支持多媒体业务需要的驱动,ATM局域网成为人们关注的一个热点,被认为是未来局域网发展的主流。ATM网络带宽大,速度高,并且能提供业务质量QOS服务,种种优点使ATM局域网在性能上大大优于传统共享媒介的局域网。然而,ATM技术与传统局域网在某些重要特征上相互冲突,因而ATM不能直接支持现有局域网的应用。现有的局域网是一种非常成熟的技术,安装数量庞大、应用程度极高,用户在网络硬件、软件方面都已做了巨大的投资。因此,无论ATM技术如何完
A brief introduction A few years ago due to the high-speed transmission of data and support for multimedia services driven, ATM LAN has become a hot spot, is considered the mainstream of future LAN development. ATM network bandwidth, high speed, and can provide quality of service QOS services, the advantages of the ATM LAN performance is much better than the traditional shared media LAN. However, ATM technologies and traditional LANs conflict with each other in some important features. Therefore, ATM can not directly support the application of existing LANs. Existing LAN is a very mature technology, a large number of installation, high degree of application, users of network hardware and software have made a huge investment. Therefore, no matter how ATM technology is finished
