摘要:

随着信息化和云化技术的发展,光传送网络(optical transport network,OTN)承载业务动态性逐步增强。光业务单元(optical service unit,OSU)作为下一代的OTN交换技术,要为高品质的企业专线和精品家庭宽带业务提供组网专线和入云专线服务。基于OSU的OTN需要能够通过端到端的管控能力,提供一体化服务及自动化快速业务开通,支持业务一跳入云。首先介绍了OSU技术产生背景、技术特征及标准化进展情况;然后提出了面向 OSU-OTN 的业务感知控制框架,满足政企专线高效承载的需求;最后对接入型OSU-OTN控制器系统端到端管控能力进行了实验验证。

关键词: OSU, OTN, 业务感知, 无损带宽调整

Abstract:

With the development of information and cloud technology, the dynamic demand for OTN service is gradually increasing.As a next generation OTN switching technology, OSU needs to provide network and cloud services for high-quality enterprise leased lines and boutique home broadband services.The OSU-based OTN needs to be able to provide integrated services and automated service provisioning through end-to-end management and control capabilities to support one-hop service into the cloud.Firstly, the background, technical characteristics, and standardization progress of OSU technology were introduced.Then, a service-aware control framework for OSU-OTN was proposed to meet the demand for efficient bearer of government and enterprise leased lines.Finally, an experimental validation of the end-to-end management and control capability of the access OSU-OTN controller system was carried out.

Key words: OSU, OTN, service awareness, hitless bandwidth adjustment
