光与无线融合接入网组网技术研究
|
摘要
现在的网络的构架大部分是在30年前建立的,那时候大部分的网络使用者都是研究人员,用途也仅仅是一小部分工作伙伴或者朋友之间交流信息。随着网络的使用范围越来越广,30年前建立的网络架构已经无法满足人们对于网络的需求。因此,我们需要一个新的网络来代替现在的网络,即未来网络。未来网络是人们目前对于今后网络发展的一个构想,如何实现未来网络目前还没有具体的规划。按照ITU-T关于未来网络总体目标的建议,本文对未来的光与无线融合接入网进行了研究。
网络虚拟化是未来网络框架中一项很重要的技术。它实现了灵活和相互隔离的网络来支持大范围的网络结构、服务和用户,而不会影响其他网络。它还可以简便的建立实验网以及加速在未来网络技术上的开发和研究。借助虚拟化手段,光和无线融合接入网将会实现跨层融合。这种融合会使接入网在物理层支持灵活性和移动性,且具有低时延、大容量和可靠性,在资源和服务方面满足未来网络服务需求。
本文首先对于光与无线融合接入网产生的背景,以及现有的光与无线接入技术进行了阐述。接下来对未来网络的总体目标进行了描述,明确未来的光与无线融合接入网的设计目标。之后对于未来网络的虚拟化框架进行了阐述,对比了虚拟网络和网络虚拟化之间的差别,提出网络虚拟化可以解决的问题,介绍了网络虚拟化的分层结构、网络虚拟化的关键技术以及虚拟化后的运营实体。
本文第三章提出了光与无线融合接入网的组网方案。其中使用的关键技术为OpenFlow技术。光与无线融合接入网的物理网络采用FiWi的网络结构,本文在FiWi网络结构的基础上进行了优化,提出了三种物理网络结构模型。之后对于其中的关键节点混合ONU和控制器的设计进行了详细的描述。并提出了如何在光与无线融合接入网的物理网络基础设施上实现网络虚拟化。
本文第四章对光与无线融合接入网进行了组网验证。本文通过实际的网络验证光与无线融合接入网方案的可行性,并对网络性能进行了测试。
第五章对本文所做工作进行了总结并对未来网络的发展进行了展望。
Most of current network architectures were constructed30years ago, which were mainly used for researchers'communication. With the development of network application, the network architecture built30years ago does not meet people's requirement. Therefore, a new network is needed to replace current network, which is future network. Future network is an idea of network development. There is no detailed planning to realize future network currently. According to ITU-T recommendation of future network's objective and design goals, this paper focuses on the convergence networking technology for optical and wireless network.
Network virtualization is a very important technology. It realizes network separation and flexibility to support large scale network, services and users. It also helps to setup experiment network and accelerate the development and research on future network technology. With network virtualization, optical and wireless access network convergences cross multiple layers. This convergence will make access network support flexibility and mobility in physical layer with low latency, high capacity and reliability. It will meet the requirement of resources and services in future network.
This paper first introduces the background and technology of optical and wireless network. Then it elaborates the objective and design goals in future network, and virtualization framework. It compares virtual network and network virtualization, analyzes what kind of problems can be solved by network virtualization and introduces hierarchical structure of network virtualization, key technology and operating entity.
Chapter3is networking scheme. Physical network is3types of optimized FiWi architecture. OpenFlow is used to realize network virtualization. After that is the detailed design of Hybrid ONU and controller.
Chapter4is design verification. Through real networking experiment, the scheme is proved to be feasible. Chapter5is the summary and gives the direction of future research.
