近年来,大量的局域网LAN是由接入子网和主干子网这两种结构组成,最常见的接入子网是4Mbit/s令牌环LAN和10Mbit/s CSMA/CD LAN,而主干子网则以100Mbit/s光纤分配数据接口LAN最为普遍。本文中将主要介绍ATM网络与传统的网络组成的混合工程的实例。 随着宽带多媒体应用的普及,目前的网络已日益不能满足通信的需求。长期以来,人们一般认为ATM是解决这一问题的最佳方案。但是目前使用的各种网络不可能全部废除,故此,寻找一种可行的方案是必然的。一个可行的经济方案是将传统的技术与ATM技术集成到一个网络中,从而满足多媒体和Client/Server应用的需求。 1.ATM混合网络结构 传统的FDDI网络、向ATM网络技术过渡,是网络技术发展的一种必然趋势。现以DEC的产品为例,介绍从传统的网络向ATM过渡的网络工程。作
In recent years, a large number of LANs are composed of access subnets and backbone subnets. The most common access subnets are 4 Mbit / s Token Ring and 10 Mbit / s CSMA / CD LAN. The backbone Network is to 100Mbit / s fiber distribution data interface LAN most common. This article will introduce the ATM network and the traditional network consisting of a mixed-case examples. With the popularity of broadband multimedia applications, the current network has been increasingly unable to meet the needs of communications. For a long time, people generally think that ATM is the best solution to this problem. However, the various networks currently used can not be completely abolished. Therefore, finding a viable solution is inevitable. A viable economic solution is to integrate traditional technologies and ATM technologies into one network to meet the needs of multimedia and Client / Server applications. 1.ATM hybrid network structure The traditional FDDI network to ATM network technology transition is an inevitable trend of network technology development. Now DEC products, for example, describes the network from the traditional network to ATM transition project. Make
