With the rapid development and deployment of the Network Function Virtualization (NFV) technology, the number and types of Network Services (NSs) in virtualized environments keep increasing significantly. However, due to the dynamic network and service status, manually customizing an NS in an NFV environment is a professional, time-consuming and error-prone task, and there is an urgent need to develop a new mechanism to automate the deployment and control process of NSs. In this work, we propose a novel Software Defined NS Deployment and Control mechanism (SDNSDC) in NFV environments. By executing the uniquely defined NS deployment and control description files, one can have the orchestrator to generate some specific virtualized middleboxes, based on which the predefined NS functions can be further configured in the NFV network. Finally, a prototype system of the proposed SDNSDC has been implemented based on the Linux container technology. The experimental results show that the proposed methods can efficiently deploy customized network services and accurately control their behaviors.

随着网络功能虚拟化（NFV）技术的快速发展和部署，虚拟化环境中网络服务（NSs）的数量和类型持续显着增长。但是，由于网络和服务的动态状态，在NFV环境中手动自定义NS是一项专业，耗时且容易出错的任务，并且迫切需要开发一种新的机制来自动化部署和控制过程NSs。在这项工作中，我们提出了一种新的软件定义的NFV环境中的NS部署和控制机制（SDNSDC）。通过执行唯一定义的NS部署和控制描述文件，编排器可以使协调器生成一些特定的虚拟化中间盒，基于这些中间盒，可以在NFV网络中进一步配置预定义的NS功能。最后，基于Linux容器技术的SDNSDC原型系统已经实现。实验结果表明，所提出的方法能够有效地部署定制的网络服务并准确地控制其行为。
