面向终端用户的轻量级网络功能虚拟化服务编排环境

针对终端用户开发与部署网络服务的问题，提出了一个基于网络功能虚拟化技术的网络服务编排环境.该环境主要包含3部分：虚拟网络功能数据模型用于适配异构的网络功能，将网络功能以可视化的形式呈献给用户；服务编排环境用于协助用户完成网络服务流程的设计；服务执行环境用于协助用户完成网络服务的部署与运行.3部分构成了轻量级虚拟网络功能编排工具（LVO）.将该工具引入相应的开发方法，用户可以在网页浏览器上通过易用的图形化界面"设计即开发"的方式开发网络服务.通过面向用户的实验和系统性能实验，评估了该网络服务生成环境.评估结果表明，LVO可有效降低普通用户的工具学习时间，提高网络服务开发的正确率.

Lightweight Network Services Orchestration Environment Based on NFV for End Users

We propose a network service orchestration environment based on network function virtualization (NFV) technology to help end users develop and deploy network services. The environment includes:a virtual network function data model for adapting heterogeneous network functions; a development environment to assist users in the design of network service processes; and a deployment environment to assist users in the deployment and execution of network services. Finally, user-oriented experiments and system performance experiments were conducted to evaluate the network service generation environment. Our evaluation shows that lightweight virtualization orchestrator can effectively reduce the tool learning time of ordinary users and improve the development accuracy of network services.
