网络信息量爆炸式增长和ＩＰ技术的普遍使用促进了宽带ＩＰ主干网的出现和发展，而宽带ＩＰ网络必须建立在现有的网络技术基础上，建立在当前最先进的网络传输技术基础上。现在典型的相关技术有ＩＰｏｖｅｒ ＡＴＭ， ＩＰ ｏｖｅｒ ＳＤＨ， ＩＰ ｏｖｅｒ ＷＤＭ等。 ＩＰ ｏ
The explosive growth of network information and the widespread use of IP technology have promoted the emergence and development of broadband IP backbone networks. However, the broadband IP network must be based on existing network technologies and based on the most advanced network transmission technologies currently. Now typical related technologies are IPover ATM, IP over SDH, IP over WDM and so on. IP o
