Abstract: 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.

Key words: network function virtualization, service orchestration environment, end-user development
