摘　　要：为满足用户服务功能链需求,加快服务功能链编程效率,设计一种面向服务功能链领域的专用语言SFCDSL.从规范化和可扩展性考虑,首先提出SFC抽象化层次框架和SFCDSL编程框架.对于SFCDSL中的服务关系采用基于面向对象设计方法,给出了基于软件定义SF和面向对象的SFC形式化定义,在此基础上重点分析了SFCDSL的对象关系设计和风格设计,之后以实现的北向扩展ETSI NFV环境的Intent和南向基于Floodlight SDN的SFC框架原型,结合典型需求实例说明了SFCDSL语言可用性、可演化性和可扩展性优势,最后与其它SFC技术进行了分析对比.In order to meet SFC requests and speed up the programming efficiency of service function chain,a domain special language SFCDSL for service function chain is designed.Considering normalization and extensibility,SFC abstraction hierarchy framework and SFCDSL programming framework are proposed.For the service relationship in SFCDSL,the object-oriented design method is adopted,and the formal definition of SFC based on software definition and object-oriented is given.On this basis,the object relationship design and style design of SFCDSL are analyzed emphatically.After that,with typical requirement examples,the SFC framework prototype which is extended the intent of ETSI NFV environment and based on Floodlight SDN,is used to illustrate the usability,evolvability and scalability advantages of SFCDSL.Finally,it is analyzed and compared with other SFC technologies.
