传输网络切片编排技术探讨

信息通讯技术的快速发展加速了各行业向数字化转型,催生了不同行业用户定制化业务需求和个性化体验。传输网络切片技术可以在现有传输网络上实现多个传输链路/切片网络,且彼此隔离,再通过引入专门的逻辑网元功能来负责编排管理传输网络切片,使传输网络可以满足不同行业用户定制化业务需求和服务等级保障。本文基于传输网络切片的需求、概念、支持的应用场景、架构和国外标准化组织传输网络切片编排技术等,探讨了传输网络切片编排技术发展、自动化和智能运维管理方案,提出了一种实现案例,并对传输网络切片编排功能部署进行了思考。

The rapid development of information and communication technology has shifted to the digital transformation of various industries.Different vertical industries users have expected the tailored service requirements and personalized experiences.In order to meet the tailored differentiated service requirements and service level assurance,the use of transmission network slice technology can provide multiple transmission connectivity/slice networks with degree of isolation,the slices must be isolated from each other,and the function of orchestration and management of transmission network slice is essential.Based on the requirements,concept,application scenarios,function architecture of transmission network slice,and the transmission network slice orchestration technology in international SDOs,this text discussed the development of the transmission network slice orchestration technology,the solution of orchestration automation,and intelligent Operation,Administration and Maintenance(OAM)of transmission network slice,gave an implementation case,also considered the deployment of the transmission network slice orchestration function.
