【摘要】：近年来随着网络技术的不断发展,出现了移动物联网、云计算等新兴技术,这导致网络设备对IP地址的需求急剧增加;目前基于IPv4的互联网在实际应用中面临很多挑战,诸如地址紧缺问题、安全问题、服务质量以及简便配置等等。面对当前形势,世界各国加速了对下一代互联网的研究。随着宽带、移动互联网业务的规模发展,电信集团IPv4地址短缺问题日益突出,部分省将陆续出现IPv4地址短缺,到2014年地址问题将会更加严重。IPv4地址紧张、消耗量大的省份,需要通过网络改造来解决业务发展的地址需求,为用户及应用提供IPv6接入与承载。IPv4地址资源紧张限制了IP技术应用的进一步发展。而移动和宽带技术的发展要求更多的IP地址。IPv6能从根本上解决这个问题。IPv6作为下一代互联网的核心协议,与IPv4相比有着巨大的优势,例如提供海量地址空间,解决IP地址枯竭问题;预留流标签功能,拥有强大的Qo S扩展功能,可实现应用流级的Qo S;提升高速移动场景下(如高铁、飞机等)的应用不中断能力;更富有层次化的路由规划,骨干层网络能更有效的汇聚路由等等。本文首先介绍了IPv6引入的契机,重点分析了IPv4向IPv6过渡的主要策略;然后介绍了西安城域网的发展现状和改造建设;在此基础上,综合考虑城域网过渡期间的基本情况,在深入开展用户需求分析和技术可实施性的基础上,根据中国电信IP城域网向下一代互联网过渡部署的互联网接入业务的承载需求,从整体上提出了一个IPv6城域网的系统设计方案,基于陕西电信IP城域骨干网的网络现状,对IP城域骨干网的网络结构、路由策略、业务承载实现、网络安全等方面的内容进行了规划,包括IPv6城域网的设计目标和总体部署方案,地址分配方案以及基于IPv6的宽带业务实现。最后给出IPv6城域网的网络设备配置以及测试情况。基于城域网的IPv6关键技术研究对于今后IPv6的正式商用和推广具有重要意义,对于IPv6的实用化进程具有重要的推进作用。
[Abstract]:In recent years, with the continuous development of network technology, emerging technologies such as the mobile Internet of things, cloud computing and other emerging technologies, which lead to a sharp increase in the demand for IP addresses of network equipment. At present, the Internet based on IPv4 is facing many challenges in practical applications. Such as address shortages, security issues, quality of service and easy configuration, and so on. Facing the current situation, countries in the world have accelerated the study of the next-generation Internet. With the development of broadband and mobile Internet services, the shortage of IPv4 addresses in telecommunications groups is becoming increasingly prominent. Some provinces will have IPv4 address shortages one after another. By 2014, the address problem will be even more serious. It is necessary to solve the address requirement of service development through network transformation, and provide users and applications with IPv6 access and carrier. IPv4 address resource shortage restricts the further development of IP technology application. The development of mobile and broadband technology requires more IP addresses. IPv6 can fundamentally solve this problem. As the core protocol of the next generation Internet, IPv6 has great advantages over IPv4, such as providing massive address space. It can solve the problem of IP address exhaustion, reserve stream label function, have powerful QoS extension function, can realize flow level QoS, improve the ability of application without interruption in high-speed mobile scenarios (such as high-speed rail, aircraft, etc.); More hierarchical routing planning, backbone layer network can be more effective convergence routing and so on. This paper first introduces the opportunity of introducing IPv6, analyzes the main strategies of transition from IPv4 to IPv6, and then introduces the development and construction of Xi'an Metropolitan area Network (man), on the basis of which, it synthetically considers the basic situation during the transition period of Metropolitan area Network (man). On the basis of deeply developing user demand analysis and technology implementation, according to the demand of China Telecom IP Metropolitan area Network (IP man) to the next generation Internet, In this paper, a system design scheme of IPv6 metropolitan area network is put forward. Based on the present situation of Shaanxi Telecom IP metropolitan backbone network, the network structure, routing strategy and service carrying capacity of IP metropolitan backbone network are realized. The content of network security is planned, including the design target and overall deployment scheme of IPv6 man, the address assignment scheme and the realization of broadband service based on IPv6. Finally, the network equipment configuration and test of IPv6 metropolitan area network are given. The research on the key technologies of IPv6 based on metropolitan area network is of great significance for the formal commercialization and popularization of IPv6 in the future, and also plays an important role in promoting the practical process of IPv6.
