【摘要】：如今,互联网的经典架构的很多方面已成定局,也被称为互联网的骨化,这成为互联网技术发展的主要障碍。目前已提出很多解决方案,比如,为提高网络可靠性而改善域内和域间的路由,为用户提供端到端的链接,为新应用(如数据中心、云计算、网络虚拟化)提供网络资源的动态服务质量管理。为应对这些需求,未来互联网的下一代架构引入了软件定义的网络这一概念。与现有网络的分布式控制模块不同,这种新型方式的核心是将控制模块从转发模块中分离并集中化。这样的解耦方式能够使得计算机平台上的控制模块中的软件部件比传统网络设备更有效、更具优势。同时,还可以保护这些设备的供应商的数据和知识产权。目前SDN(Software Defined Network,SDN)受到来自学术界和工业界的密切关注。本文从不同的角度介绍SDN,包括SDN的使用案例和相关标准化,集中式SDN模型和分布式SDN模型的优缺点,以及向混合式SDN模型演变的挑战和机遇等。车联网是移动互联网、物联网向业务实质和纵深发展的必经之路,是未来信息通信、环保、节能、安全等发展的融合性技术。但是由于其自身技术尚不完善,仍然有很多问题需要解决,比如车联网信息交互过程中的延时问题及成功率问题。本文主要关注的是车联网中的频谱规划和数据存储检索问题。对于频谱规划,使用软件定义的方式实现频谱感知和频谱预知,从而提高数据传输的成功率;使用Lucene全文检索方式,实现数据的高效存储和检索。通过使用软件定义技术,可以提高车联网的数据传输效率,降低数据传输发生冲突的可能性,从而保证车联网的安全性。并且,本文通过软件定义网络技术在模拟环境中对其进行验证和完善,将SDN技术应用于车联网的信息交互之中,成功地证明了SDN的有效性。最后,本文从各种方向中SDN的发展和应用以及SDN在安全性方面的挑战和机遇。通过不同角度的介绍,从而阐述和分析SDN的发展和应用前景。
[Abstract]:Today, many aspects of the classic architecture of the Internet have become inevitable, also known as Internet ossification, which has become a major obstacle to the development of Internet technology. Many solutions have been proposed, such as improving intra-domain and inter-domain routing to improve network reliability, providing end-to-end links to users, and providing new applications (such as data centers, cloud computing, etc.) Network virtualization) provides dynamic quality of service management for network resources. To meet these needs, the next generation architecture of the future Internet will introduce the concept of software defined network. Different from the existing distributed control module, the core of this new way is to separate and centralize the control module from the forwarding module. This decoupling method can make the software components in the control module on the computer platform more effective and more advantageous than the traditional network equipment. It also protects the data and intellectual property rights of suppliers of these devices. At present, SDN (Software Defined Network (SDN) has received close attention from academia and industry. This paper introduces SDNs from different angles, including the use cases and related standardization of SDN, the advantages and disadvantages of centralized SDN model and distributed SDN model, as well as the challenges and opportunities of evolution to hybrid SDN model. Car networking is the only way for mobile Internet to develop to business essence and depth. It is a fusion technology for the future development of information communication, environmental protection, energy saving, security and so on. However, due to the imperfection of its own technology, there are still many problems to be solved, such as the delay and success rate in the process of information interaction. This paper focuses on spectrum planning and data storage and retrieval in vehicle networking. For spectrum planning, spectrum sensing and spectrum prediction are realized by means of software definition, so as to improve the success rate of data transmission, and Lucene full-text retrieval is used to achieve efficient data storage and retrieval. By using software definition technology, the efficiency of data transmission can be improved, the possibility of data transmission conflict can be reduced, and the security of vehicle networking can be ensured. Furthermore, this paper verifies and perfects the network technology by software definition in the simulation environment, and applies the SDN technology to the information exchange of the vehicle network, which proves the effectiveness of SDN successfully. Finally, the development and application of SDN and the security challenges and opportunities of SDN are discussed. Through the introduction of different angles, the development and application prospect of SDN are expounded and analyzed.
