国内多个运营商骨干路由器网络的互联接口普遍采用 SDH(同步数字体系)接口，而非以太网接口来简化网络的运维管理。文章通过对高速率传送技术及光接口格式的分析，提出在骨干路由器网的高速互联接口采用 OTN(光传送网络)接口格式的技术可行性和在路由器上需要支持的 OTN 开销建议。对路由器的 OTN 接口的各项功能和能力进行了实验室测试，验证了根据现有标准规范开发的路由器 OTN 接口在功能、能力和互通性等方面可以满足骨干路由器网络的维护管理需求。

Multiple Chinese carriers commonly use SDH,but not Ethernet interfaces for their backbone router network inter-links,so as to simplify their network operation,maintenance and management.On the basis of analyzing high-rate transport technologies and optical interface formats,this paper discuses the technical feasibility of adopting OTN interface format in high-rate interlinks of backbone router networks and the need of supporting OTN overhead in the routers.It conducts laboratory tests on the functions and capabilities of the OTN interfaces of the routers of several venders,verifying that routers developed in compliance of the existing standards and specifications satisfy the requirements for the maintenance and management of back-bone router networks in terms of functions,capabilities and interworking.
