【摘要】：随着互联网的快速发展和网络新业务的不断出现,对光传输网络提出了更多的要求,在这种趋势下,传统的网络分层架构已无法满足日益增长的需求,对于互联网的发展已经成为一个障碍,这类问题被称为网络僵化问题。在此背景下,网络虚拟化已经越来越多地被看作是互联网僵化的一个解决方案。本文介绍了光网络的特点,在分析现有技术的基础上,提出了基于Web Service的虚拟化光网络资源管理技术。通过对光网络虚拟化概念及其研究意义的分析,给出了本文的主要理论背景。分析了本文的涉及的主要技术架构,包括Web Service和.NET相关技术。其次,研究了光网络的虚拟化关键技术问题,包括光网络节点虚拟化和光网络链路虚拟化技术,对光网络资源进行了属性抽象,为虚拟化光网络资源管理做了准备。并阐述了资源映射的过程,同时对映射算法进行了对比分析和研究。在Visual Studio集成开发环境下,使用C#编程语言结合.NET编程平台重点设计了基于Web Service的虚拟化光网络资源管理模拟系统,模拟了普通用户和管理员用户对光资源模块各种管理和操作行为。最后,展示了基于Web Service虚拟化光资源管理运行实例,通过普通用户和管理员两种角色对系统进行了深度测试,验证了光网络资源管理系统的可行性和有效性。本课题设计的系统可以有效解决网络僵化问题,提高网络管理的灵活性和方便性。
[Abstract]:With the rapid development of the Internet and the continuous emergence of new network services, the optical transmission network has put forward more requirements. Under this trend, the traditional network layered architecture can no longer meet the increasing demand. The development of the Internet has become an obstacle, such problems are called network ossification. Network virtualization has been more and more regarded as a solution to Internet fossilization. This paper introduces the characteristics of optical network, based on the analysis of existing technologies, This paper puts forward the resource management technology of virtualized optical network based on Web Service. Through the analysis of the concept of virtualization of optical network and its research significance, the main theoretical background of this paper is given, and the main technical framework involved in this paper is analyzed. Secondly, the key technologies of optical network virtualization, including optical network node virtualization and optical network link virtualization, are studied. This paper makes preparation for resource management of virtualized optical network, and expounds the process of resource mapping. At the same time, it makes a comparative analysis and research on mapping algorithm. Under the environment of Visual Studio integrated development, Using C # programming language and .NET programming platform, the virtual optical network resource management simulation system based on Web Service is designed, which simulates all kinds of management and operation behaviors of optical resource module by ordinary users and administrator users. An example of virtualization of optical resource management based on Web Service is presented, and the system is tested in depth through two roles: ordinary user and administrator. The feasibility and effectiveness of the optical network resource management system are verified. The system designed in this paper can effectively solve the problem of network rigidity and improve the flexibility and convenience of network management.
