SDN/NFV发展中的关键:编排器的发展与挑战

网络功能虚拟化(NFV)和软件定义网络(SDN)已被业界普遍认定为下一代电信网络发展的主要方向,编排器作为未来网络的“大脑”,成为运营商灵活管理网络、最大化发挥新技术优势的关键.首先阐述了编排器在下一代网络中的核心地位,并对编排器的技术架构进行介绍.而后从标准化和开源的角度对编排器产业发展情况进行介绍和分析.最后阐述了编排器产业发展中标准与开源的关系,编排器与网管运营支撑系统(OSS)的融合、编排器对SDN的支持以及依托编排器实现网络自动化智能化运营的理念.

Key of SDN/NFV development: development and challenge of orchestrator

Network function virtualization (NFV) and software defined networking (SDN) have been widely recognized as the main direction of the development of the next generation telecom network,and as the brain of the future network,orchestrator is the key for the operators to manage the network flexibly and maximize the advantages of new technologies.Firstly,the core position of orchestrator in the next generation network was described,and the technical architecture of orchestrator was introduced.Then,the development of orchestrator in the perspective of standardization and open source were introduced and analyzed.Finally,the relationship between standardization and open source was elaborated,including the integration of orchestrator and OSS,the support of orchestrator for SDN and the idea to realize the intelligent and automatic network operation relying on orchestrator.
