摘要

传统光传输网络正逐渐走向开放与解耦，“烟囱式”的单厂商单域管理模式也在软件定义网络（software defined network，SDN）理念渗透下向多厂商、多域统一管理模式发展，考虑到传输网络的设备差异性和协议复杂性，对传送SDN管控提出了一定的要求。首先，提出了介于黑盒设备与白盒设备之间的灰盒概念；然后，以灰盒化的接入型光传送网络（optical transport network，OTN）设备为例，探讨了接入型OTN的SDN统一管控关键技术，包括开放管控架构、业务模板化、拓扑自动生成、设备自动上线、设备远程升级等；最后，结合实践阐述了接入型OTN统一管控系统的实现和现网应用情况。

Abstract

Traditional optical transport network is gradually becoming open and disaggregated

and the chimney-type single-vendor and single-domain management mode is also developing to the multi-vendor and multi-domain management mode with the penetration of software defined network (SDN) concept.Considering the equipment difference and protocol complexity of transport network

application of SDN management and control for transport network faces challenges.Firstly

the concept of grey-box was proposed

which was between black-box and white-box.Then

taking grey-box access OTN as an example

the key technologies of SDN unified management and control of access-type OTN were discussed

including management and control architecture

service template

automatic topology generation

automatic equipment online

remote upgrade of equipment

in-band DCN communication between different vendors

etc.Finally

the application of access-type OTN unified management and control system in real network was described.
