摘　　要：采用在SDH网上直接运行IP(IP over SDH)的骨干网提供了高效、经济的高速IP业务传输.由于IP业务的急剧增长、SDH传输体制的普及和路由器技术的发展,使IP over SDH得到了发展.该网采用点到点协议,利用高层数据链路控制组帧.波分复用技术可充分利用单模光纤容量,以满足不断增长的电信与Internet服务的需要.随着千兆位高速路由器技术的成熟和IP业务的发展,IP over SDH将被广泛应用.IP over SDH backbone network provides economical high-speed IP service transmission. The explosive growth of IP service, the popularization of SDH transmission system and the development of router technologies lead to the progress of IP over SDH. The network adopts point-to-poir protocols and uses high-layer data link to control framing WDM technologies make good use of the capacity of single mode fiber to meet the increasing demand for telecom an Internet services. With the mature of Gigabit router technol ogy and the development of IP services, IP over SDH will b widely applied.
