【摘要】：下一代网络是业务驱动的网络,如何高效、灵活地开发和部署业务是下一代网络的核心议题。传统的业务开发方式,难以克服开发周期长,业务种类有限等问题,不能适应下一代网络业务开发的需求。而Parlay API, SIP Servlet API等业务开发接口,要求开发人员具有较强的业务能力和编码能力,难以被广泛使用。要进一步推动下一代网络的发展,有待提出一种新的业务生成方案,最大限度挖掘业务开发的潜力,扩大开发者的范围。云计算的概念自提出以来,以其资源弹性组织、按需取用的特色,得到了广泛的研究和应用。在资源融合,平台无关性方面,云计算和下一代网络的理念有着共通之处。如果能够结合二者的优点,将为下一代网络的发展注入新的活力。本文在对电信业务开发和云平台架构进行了研究之后,提出了一种基于云计算的业务开发环境设计方案。该环境依托于电信云平台提供的业务资源和管理能力,开放图形化的业务开发接口,开发者利用云中丰富的服务资源,组合和搭建业务。相比于传统业务开发方式,这种方案具有明显的优势。首先,业务开发不再依赖于特定的开发环境,云计算的资源弹性利用和容错机制,为开发过程提供了极大的便利；其次,具有可扩展的业务开发能力,利用云中丰富的服务资源,开发者可以组合出更多新型的业务。为了进一步降低开发难度,本文还提出了一种更大粒度的业务开发方式—一基于模板的业务组装。业务模板是在业务流程的基础上,封装部分业务逻辑,开放一些变化点供用户配置,从而生成具有个性化的业务。业务模板的自动化组装也是本文的研究内容之一,借助语义Web和本体技术,实现用户需求到具体业务的自动转化。
[Abstract]:The next generation network (NGN) is a service driven network. How to develop and deploy services efficiently and flexibly is the core issue of NGN. The traditional way of business development is difficult to overcome the problems of long development cycle and limited service types, and can not meet the needs of the next generation network service development. Parlay API, SIP Servlet API and other business development interfaces require developers to have strong business ability and coding ability, so it is difficult to be widely used. In order to further promote the development of NGN, we need to propose a new service generation scheme to maximize the potential of business development and expand the scope of developers. Since the concept of cloud computing was put forward, it has been widely studied and applied because of its flexible organization of resources and the characteristics of taking advantage of demand. In terms of resource convergence, platform independence, cloud computing and next-generation networks have common ideas. If we can combine the advantages of the two, it will inject new vitality into the development of next-generation network. After the research of telecom service development and cloud platform architecture, this paper proposes a design scheme of business development environment based on cloud computing. The environment is based on the business resources and management capabilities provided by the telecom cloud platform, and open the graphical business development interface. The developers use the rich service resources in the cloud to combine and build the services. Compared with the traditional business development mode, this scheme has obvious advantages. First, business development is no longer dependent on a specific development environment. The flexible utilization of resources and fault-tolerant mechanisms of cloud computing provide great convenience for the development process. With the rich service resources in the cloud, developers can combine more new business. In order to further reduce the difficulty of development, this paper also proposes a more granular business development method-template based business assembly. The business template is based on the business process, encapsulates some business logic, opens some change points for the user to configure, thus generates the personalized service. The automatic assembly of business templates is also one of the research contents in this paper. With the help of semantic Web and ontology technology, the automatic transformation from user requirements to specific services is realized.
