Internet backbone Internet 骨干网
几台计算机连接起来,互相可以看到其他人的文件,这叫局域网,整个城市的计算机都连接起来,就是城域网,把城市之间连接起来的网就叫骨干网。这些骨干网是国家批准的可以直接和国外连接的互联网。其他有接入功能的ISP想连到国外都得通过这些骨干网。
组成“骨干网”通常是用于描述大型网络结构时经常使用的词语,描述网络结构,主要是要看者清楚网络拓扑结构,而非具体使用的传输方式或协议。骨干网一般都是广域网:作用范围几十到几千公里。
骨干网是由多种传输方式,多种协议组合构成的。
我们的四大骨干网有CHINANET,CERNET,CSTNET,CHINAGBN
