摘要:
隨著因特網(wǎng)的迅速發(fā)展,作為Internet的關(guān)鍵的現(xiàn)行的網(wǎng)際協(xié)議(IPv4)的缺點(diǎn)逐漸顯現(xiàn)出來:例如地址的短缺、對無線網(wǎng)絡(luò)的支持不夠等。因此,IPv4的替代者IPv6出現(xiàn)了。相比起IPv4來,IPv6有著比IPv4多得很多的地址空間;更靈活的首部格式;簡化了協(xié)議;允許對網(wǎng)絡(luò)資源的預(yù)分配;并且可以使協(xié)議繼續(xù)演變,增加新的功能。雖然IPv6很好,但是要想全面取代IPv4還需要時間,因此IPv4和IPv6的兼容問題是我們關(guān)心的,而實(shí)現(xiàn)IPv6過渡現(xiàn)在一般采用兼容IPv4的IPv6地址、雙協(xié)議棧和隧道代理三種方式;另外一個問題就是現(xiàn)在流行的移動IPv6是怎么實(shí)現(xiàn)的呢?
關(guān)鍵詞:IPv6、隧道、移動IPv6、第三代移動通信、原籍地址、原籍代理、服務(wù)質(zhì)量、轉(zhuǎn)交地址;
The realization of IPv6 and the wairless networks of IPv6
Abstract:
With the fast development of Internet, the IPv4 ,as the key protocol of Internet ,couldn’t satisfy the modern Internet . For instance, the shortage of address space and the trouble of hardly to support the wireless networks full.As a result,IPv6 was presented to take place of IPv4. In contrast to IPv4, the advantages of IPv6 are as following: it has more address space than IPv4; it has free style of the base header ; it simplifies the protocol; it allows to pre-distribute the resource of Internet and to evolve the protocol and add the new functions. Although the significant of IPv6 ,take place of IPv4 should a long term. So we must learn how to let the IPv6 work over the IPv4’s net and there are three methods to achieve the development of IPv6 such as IPv6 address suit for IPv4,dual-stack system and the tunnel broker; and the other function of how to achieve the mobile IPv6.

一.前言(IPv6概述):
1. IPv4的局限性、缺點(diǎn)和IPv6的特點(diǎn)
90年代以來,采用TCP/IP協(xié)議的Internet獲得空前的成功,說明IP協(xié)議設(shè)計(jì)是靈活和強(qiáng)有力的,并且它能夠連接小至幾個節(jié)點(diǎn),大至成千上萬的互聯(lián)主機(jī)。但是,隨著Internet用戶的不斷增加,目前IPv4的地址已不夠分配的需求。而新的計(jì)算機(jī)和通信技術(shù)在不斷發(fā)展,用戶對網(wǎng)絡(luò)服務(wù)的要求也越來越高,比如那些學(xué)要協(xié)議保證一定的時延限制的實(shí)時話音和視頻通信。然而,目前的IPv4缺少有效的機(jī)制來滿足這些需求。因此,我們必須考慮升級現(xiàn)有的IPv4,總結(jié)起來IP協(xié)議升級的原因以及可以改進(jìn)之處包括一下幾點(diǎn):
地址空間的局限性:由于IP地址的分配不合理,并且IPv4地址有即將用盡......
