【摘要】：互聯(lián)網(wǎng)從誕生之初發(fā)展到現(xiàn)在,已經(jīng)有三十多年的歷史了。目前,互聯(lián)網(wǎng)已經(jīng)成為人們?nèi)粘Ｉ�活中不可或缺的一部分�?接入互聯(lián)網(wǎng)的主機(jī)數(shù)量在不斷地增加,網(wǎng)民數(shù)量也在飛速地增長著,這些都促使著互聯(lián)網(wǎng)的高速發(fā)展。隨著互聯(lián)網(wǎng)的發(fā)展,越來越多的技術(shù)問題開始暴露出來,互聯(lián)網(wǎng)發(fā)展中暴露出來的技術(shù)問題,使得針對(duì)互聯(lián)網(wǎng)體系結(jié)構(gòu)的研究成為一個(gè)重要課題。本文主要針對(duì)互聯(lián)網(wǎng)發(fā)展中所面對(duì)的IP地址空間匱乏和路由表爆炸問題,對(duì)互聯(lián)網(wǎng)體系結(jié)構(gòu)進(jìn)行研究,尋找出一種更好地解決這兩個(gè)問題的方法。 為有效解決基于IPv4的互聯(lián)網(wǎng)在發(fā)展過程中暴露出來的IP地址空間匱乏、路由表爆炸等問題,以及針對(duì)現(xiàn)有IP地址空間擴(kuò)展方面的研究存在的問題,提出結(jié)合自治系統(tǒng)號(hào)對(duì)IP地址空間進(jìn)行擴(kuò)展的分層次地址結(jié)構(gòu)(ASN+IP)。將自治系統(tǒng)號(hào)封裝到IP數(shù)據(jù)包中,使其成為IP地址的一部分,可以使IP地址空間得到極大的擴(kuò)展,路由器的路由信息庫(RIB)也可以得到極大程度的壓縮。研究結(jié)果表明,在ASN+IP體系結(jié)構(gòu)下,IP地址空間理論上可以擴(kuò)展到現(xiàn)有地址空間的216倍,對(duì)路由器的RIB的壓縮平均可壓縮到原來的20%左右。 文章首先針對(duì)廣泛使用的IPv4地址體系結(jié)構(gòu)進(jìn)行介紹和分析,然后在保證IPv4體系結(jié)構(gòu)原有特性不變的基礎(chǔ)上,對(duì)IPv4協(xié)議進(jìn)行改良,形成一個(gè)新的地址空間體系結(jié)構(gòu)ASN+IP模型,著重闡述了ASN+IP模型下的尋址方案、IP數(shù)據(jù)報(bào)文格式和主機(jī)之間的通信過程;最后以BGP協(xié)議和DNS協(xié)議為代表,分析了ASN+IP模型對(duì)其它互聯(lián)網(wǎng)協(xié)議的影響。
[Abstract]:From the birth of the Internet to the present, has been more than 30 years of history. At present, the Internet has become an indispensable part of people's daily life, the number of mainframe access to the Internet is constantly increasing, and the number of Internet users is also growing rapidly, all of which promote the high-speed development of the Internet. With the development of Internet, more and more technical problems begin to be exposed. The technical problems exposed in the development of Internet make the research on Internet architecture become an important topic. Aiming at the shortage of IP address space and the explosion of routing table in the development of Internet, this paper studies the architecture of Internet and finds a better way to solve these two problems. In order to effectively solve the problems such as the lack of IP address space and the explosion of routing table exposed during the development of IPv4-based Internet, as well as the problems existing in the research on the expansion of existing IP address space, A hierarchical address structure (ASN IP).) which extends IP address space with autonomous system number is proposed. By encapsulating the autonomous system number into the IP packet and making it a part of the IP address, the IP address space can be greatly expanded, and the router's routing information base, (RIB), can also be greatly compressed. The results show that under the ASN IP architecture, the IP address space can theoretically be extended to 216 times of the existing address space, and the average compression of the router's RIB can be compressed to about 20% of the original address space. This paper first introduces and analyzes the widely used IPv4 address architecture, then on the basis of keeping the original characteristics of IPv4 architecture unchanged, the IPv4 protocol is improved to form a new address space architecture ASN IP model. The addressing scheme under the ASN IP model, the format of the IP data message and the communication process between the hosts are described emphatically. Finally, taking BGP protocol and DNS protocol as representative, the influence of ASN IP model on other Internet protocols is analyzed.
