介绍了万兆以太网的协议体系结构及其物理拓扑结构。万兆以太网在极大地增加网络带宽的同时 ,仍遵循原有的 80 2 .3协议体系结构 ,能与已有的 10M/ 10 0M/ 10 0 0M以太网兼容 ,扩展性强 ,并尽可能地保护原有的在网络管理与维护、研究与开发等方面的投资。万兆以太网以其简单、快速、性价比高的特点 ,在局域网、城域网乃至广域网中都将会有广泛的应用 ,并能实现将以传送语音为主的网络与以传送数据为主的网络平滑无缝地统一起来 ,实现全网统一化 ,因此具有广阔的发展前景
Introduces the 10 Gigabit Ethernet protocol architecture and its physical topology. While greatly increasing the network bandwidth, 10 Gigabit Ethernet still follows the original 80 2 .3 protocol architecture and is compatible with the existing 10M / 100M / 100M Ethernet networks with high expansibility and as much as possible To protect the original network management and maintenance, research and development and other aspects of investment. 10 Gigabit Ethernet with its simple, fast, cost-effective features in the LAN, MAN and even the wide area network will have a wide range of applications, and will be able to achieve the voice of the main network to send data and to send data-based The network seamlessly unified, to achieve the entire network unified, so has broad prospects for development
