摘要
在铁路光传送网(OTN)环境下,对不同厂家设备现有的跨域保护方式进行分析,并在铁路现网骨干传输系统对不同厂家的OTN系统进行了跨域保护互通测试,验证不同厂家的OTN系统业务接口的互通性能和SNCP保护互通性能等。测试结果表明,基于域间OTUk接口实现不同厂家设备互联互通,可以满足现网跨域业务功能和性能要求,而且提高了业务的传输效率,同时增强了业务安全性。
Existing inter-domain protection methods for railway OTN systems from different vendors are analyzed. Inter-domain protection interconnection tests have also been carried out in rail- way OTN networks from different vendors in hope of validating the interconnectivity of service interfaces and SNCP protection of the OTN systems from different vendors. The tests shown that the interconnection based on inter-domain OTUk interface for the equipment from different vendors can satisfy the function and performance requirements of inter-domain service, thus impro- ving the transmission efficiency of services and enhancing the security of services.
