中国网络通信公司已经正式启动该公司第一个高速互联网示范工程,即北京—济南、北京—武汉长途光缆工程建设。这标志着中国网络通信公司拉开了高速互联网络建设序幕。中国网通公司去年宣布将建设一个覆盖范围为15城市的高速 IP 通信网。该网络将采用密集波分复用和高速路由相结合的技术,主要提供高速、大信息量的信息疏通和转接。网通公司所需的光缆路由长度超过了7000公里,其数据流将承载在 DWDM 光传输网络上。每个DWDM 的拨通到可以承载2.5Gpbs 速率的数据流。在 DWDM 的光传输网络的基础上,采用千兆路由交换技术或千兆以太网技术建设 IP 骨干网络,在核心配置
China’s network communications company has officially launched the company’s first high-speed Internet demonstration project, that is, Beijing - Jinan, Beijing - Wuhan long-distance optical cable project. This marks the beginning of the rapid development of China’s Internet communications company opened the Internet. China Netcom announced last year it will build a high-speed IP communications network covering 15 cities. The network will use a combination of dense wavelength division multiplexing and high-speed routing technology, mainly to provide high-speed, large amount of information to clear and transfer information. Netcom companies need cable routing length of more than 7000 km, the data stream will be carried in the DWDM optical transport network. Each DWDM dials to a data stream that can carry 2.5Gpbs. On the basis of DWDM optical transmission network, using Gigabit routing switching technology or Gigabit Ethernet technology to build IP backbone network, the core configuration
