向交换型网间网发展 网络的新技术,强大的新性能,这正是当今的企业网络用户所要求的。网络管理者们为满足商业需求,在能保护他们现有投资的基础设施网络的前提下,需要建立一个可提供扩展带宽,有良好扩展性,也是易管理的网络。 面对如此严峻的挑战,许多网络企业正在迅速向一个新型网络体系结构——交换型网间网发展。交换型网间网在现有共享介质网络中集成交换设备,优化路由选择和交换。在桌面和工作组级添加LAN交换机,可以满足扩展带宽的要求,并减少网络阻塞。 有了新型骨干网技术,如异步传输模式(ATM)交换和ATM路由,网络可以提供今天高吞吐服务所要求的骨干网带宽。
The development of new technologies, powerful new capabilities for switched networks, which are required by today’s corporate network users. To meet business needs, network managers need to build a network that offers scalable bandwidth, scalability, and manageability, while protecting their existing investment infrastructure network. Faced with such a severe challenge, many network enterprises are rapidly developing into a new type of network architecture, the switched network. Switched internetworks integrate switching equipment in existing shared media networks to optimize routing and switching. Add LAN switches at the desktop and workgroup levels to meet expanded bandwidth requirements and reduce network congestion. With new backbone technologies such as Asynchronous Transfer Mode (ATM) switching and ATM routing, the network can provide the backbone bandwidth required by today’s high-throughput services.
