【摘要】：近年來隨著網(wǎng)絡(luò)技術(shù)的不斷發(fā)展,出現(xiàn)了移動物聯(lián)網(wǎng)、云計算等新興技術(shù),這導(dǎo)致網(wǎng)絡(luò)設(shè)備對IP地址的需求急劇增加;目前基于IPv4的互聯(lián)網(wǎng)在實際應(yīng)用中面臨很多挑戰(zhàn),諸如地址緊缺問題、安全問題、服務(wù)質(zhì)量以及簡便配置等等。面對當(dāng)前形勢,世界各國加速了對下一代互聯(lián)網(wǎng)的研究。隨著寬帶、移動互聯(lián)網(wǎng)業(yè)務(wù)的規(guī)模發(fā)展,電信集團(tuán)IPv4地址短缺問題日益突出,部分省將陸續(xù)出現(xiàn)IPv4地址短缺,到2014年地址問題將會更加嚴(yán)重。IPv4地址緊張、消耗量大的省份,需要通過網(wǎng)絡(luò)改造來解決業(yè)務(wù)發(fā)展的地址需求,為用戶及應(yīng)用提供IPv6接入與承載。IPv4地址資源緊張限制了IP技術(shù)應(yīng)用的進(jìn)一步發(fā)展。而移動和寬帶技術(shù)的發(fā)展要求更多的IP地址。IPv6能從根本上解決這個問題。IPv6作為下一代互聯(lián)網(wǎng)的核心協(xié)議,與IPv4相比有著巨大的優(yōu)勢,例如提供海量地址空間,解決IP地址枯竭問題;預(yù)留流標(biāo)簽功能,擁有強(qiáng)大的Qo S擴(kuò)展功能,可實現(xiàn)應(yīng)用流級的Qo S;提升高速移動場景下(如高鐵、飛機(jī)等)的應(yīng)用不中斷能力;更富有層次化的路由規(guī)劃,骨干層網(wǎng)絡(luò)能更有效的匯聚路由等等。本文首先介紹了IPv6引入的契機(jī),重點(diǎn)分析了IPv4向IPv6過渡的主要策略;然后介紹了西安城域網(wǎng)的發(fā)展現(xiàn)狀和改造建設(shè);在此基礎(chǔ)上,綜合考慮城域網(wǎng)過渡期間的基本情況,在深入開展用戶需求分析和技術(shù)可實施性的基礎(chǔ)上,根據(jù)中國電信IP城域網(wǎng)向下一代互聯(lián)網(wǎng)過渡部署的互聯(lián)網(wǎng)接入業(yè)務(wù)的承載需求,從整體上提出了一個IPv6城域網(wǎng)的系統(tǒng)設(shè)計方案,基于陜西電信IP城域骨干網(wǎng)的網(wǎng)絡(luò)現(xiàn)狀,對IP城域骨干網(wǎng)的網(wǎng)絡(luò)結(jié)構(gòu)、路由策略、業(yè)務(wù)承載實現(xiàn)、網(wǎng)絡(luò)安全等方面的內(nèi)容進(jìn)行了規(guī)劃,包括IPv6城域網(wǎng)的設(shè)計目標(biāo)和總體部署方案,地址分配方案以及基于IPv6的寬帶業(yè)務(wù)實現(xiàn)。最后給出IPv6城域網(wǎng)的網(wǎng)絡(luò)設(shè)備配置以及測試情況�；诔怯蚓W(wǎng)的IPv6關(guān)鍵技術(shù)研究對于今后IPv6的正式商用和推廣具有重要意義,對于IPv6的實用化進(jìn)程具有重要的推進(jìn)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.
