【摘要】 中国石油油气生产物联网专网是集团内部各统建系统生产数据传输的通信网络,专网的建设主要是保障各统建系统的稳定运行和生产数据传输的实时高效及安全可靠,所以油气生产物联网专网是重要的数据通信网络。IPv4协议是当今计算机网络的主流协议,中国石油生产专网目前主要采用IPv4协议。由于油气生产物联网的网络终端数目巨大,大批量的传感器、移动设备需要接入网络,传统的IPv4协议因其地址分配的局限性已经不能满足石油企业对地址分配的需求。而新一代网络协议IPv6协议的地址长度为128位,可以提供2^128个地址,打破了传统网络的藩篱,能有效的解决地址匮乏问题。同时,IPv6自身拥有简洁的数据报头,大大提高了数据包的路由转发速率,进一步满足了专网数据传输实时性的要求,因此,本文对IPv6协议在油田专网上的运用、IPv6和IPv4协议过渡中出现的问题、IPv6地址规划分配管理以及专网安全性等方面进行了研究,具体的工作内容如下:1.本文分析国内外IP v6技术的研究与应用现状,研究IP v6协议的技术特点,并根据IPv6与IPv4过渡时期的主要过渡技术,分析过渡时期存在的问题,结合油气生产物联网IPv6专网与IPv4生产网之间的过渡需求,确定专网建设的过渡策略;2.由于油气生产专网网络规模大,业务应用众多,且存在IPv6地址量大的问题,本文以某大型油气田为试验对象,提出了IPv6地址的分配方案,解决IPv4不能满足地址需求的局限性;3.分析现有专网的网络现状,根据IPv6油气生产物联网专网的应用需求,设计网络架构、专网建设的组网方案;利用过渡技术设计过渡方案,并通过对油田现场模拟环境的测试,验证了过渡方案选择的正确性及适用性;4.依据信息安全等级保护原则,分析专网的安全需求,从专网的接入防护、网络边界防护以及数据中心防护等方面,设计详细的安全防护方案,为最终构建低时延、高可靠、广覆盖的大型IPv6专网提供理论依据及现实意义。更多还原

【Abstract】 The private network of oil and gas production of IOT is a communication network for production data transmission in the intra-group construction system. The construction of the private network is used to mainly guarantee the stable running of construction system and make sure real-time, efficiency, security and reliability of production data transmission.At present, IPv4 protocol is the mainstream protocol of computer network. Most of the Chinese private network of oil production uses IPv4 protocol. Since there are many network terminals in the oil and gas production of IOT, mass sensors and mobile devices are needed to be access to the network. The traditional IPv4 protocol can only provide 16M addresses. Obviously, this does not meet the needs for addresses for the oil companies. While IPv6 protocol, which is a new generation of the network protocol, has 128 address and can provide 2^128 addresses. It breaks the traditional networks limitations and is effectively capable to solve the addresses shortages. Therefore, in this paper, we study the application of IPv6 protocol on oil field private network; the problems that occur in the transition from IPv4 to IPv6, IPv6 address planning and assignation management as well as private network security etc.1. The research and application situation of IPv6 technology is analyzed and the features of IPv6 protocol technology are studied. Besides, based on the main transition technologies of IPv6 and IPv4 transition period, the problems existing in the transition period are analyzed. The transition strategy of the construction of the private network is determined according to transition requirements of the oil and gas production IOT private network between IPv6 and IPv4.2. Due to the oil and gas production private network scale, many business applications, and the problems of large quantities of IPv6 addresses, in this paper, a large oil and gas fields is selected as the tested object. The IPv6 address allocation scheme is proposed to solve the limitations that IPv4 can not meet the address requirements.3. The present situation of existing private network network is analyzed. The construction of the network architecture and private network scheme is designed based on the application requirements of the oil and gas production IPv6 private network. The transition technology is designed by making use of the transition technology. At the same time, the selective correctness and applicability of transitional scheme is verified through the test on the oil field site simulation environment.4. Based on the principles of information security rank protection, we analysize private network security requirements, access protection from private network, network border protection and data center protection. Besides, safety protection scheme is designed in detailed. It provides theoretical basis and practical significance to finally bulid low latency, high reliability, and wide coverage of IPv6 private network.更多还原
