Next generation network is a type of network driven by services and the service delivery technology is the key topic in NGN.A series of recommendations related to service delivery technology published by ITU-T were summarized firstly,and then the architecture and capabilities of the latest released recommendation,next generation network service integration and delivery environment (NGN-SIDE),were discussed and compared with some relevant standards released by other international organizations in detail.Based on NGN-SIDE,a detailed service delivery procedure of a compose service named “book a trip” was also designed.Finally,these research topics in future on NGN service delivery technique were probed in advance.%下一代网络(NGN)是业务驱动型网络,业务分发技术是下一代网络的关键技术.首先总结了国际电信联盟标准化局(ITU-T)在业务分发研究中发布的一系列成果,然后对其最新发布的下一代网络业务集成和分发环境(NGN-SIDE)的架构和功能做了详细论述,并与其他国际组织发布的业务分发相关标准进行了比较,设计了一个基于NGN-SIDE的“预订旅行”业务分发流程,最后对NGN业务分发技术的未来研究方向进行了展望.
