【摘要】：隨著信息技術(shù)的高速發(fā)展，人們已經(jīng)快速進(jìn)入了信息時(shí)代。以計(jì)算機(jī)為主開發(fā)的因特網(wǎng)（Internet），主要采用的是以分組傳送模式為基礎(chǔ)的IP交換技術(shù)。IP技術(shù)應(yīng)用廣泛，技術(shù)簡(jiǎn)單，可擴(kuò)展性好，路由靈活，易于實(shí)現(xiàn)異種網(wǎng)絡(luò)的互聯(lián)，采用無(wú)連接技術(shù)，適于非實(shí)時(shí)業(yè)務(wù)的通信，缺點(diǎn)是帶寬資源有限、無(wú)法保證服務(wù)質(zhì)量。隨著寬帶實(shí)時(shí)性業(yè)務(wù)在人們?nèi)粘Ｉ钪械钠占�，傳統(tǒng)IP網(wǎng)絡(luò)無(wú)法適應(yīng)未來(lái)通信的發(fā)展。以電信為主開發(fā)的寬帶綜合業(yè)務(wù)數(shù)字網(wǎng)（B-ISDN），其核心是ATM交換技術(shù)。ATM技術(shù)是以分組傳送模式為基礎(chǔ)并融合了電路傳送模式的優(yōu)點(diǎn)發(fā)展而來(lái)，兼具分組傳送模式和電路傳送模式的優(yōu)點(diǎn)。ATM技術(shù)采用異步時(shí)分復(fù)用方式，實(shí)現(xiàn)了動(dòng)態(tài)分配帶寬，可適應(yīng)任意速率的業(yè)務(wù)，，采用面向連接的工作方式，交換快速，保證服務(wù)質(zhì)量，缺點(diǎn)是網(wǎng)絡(luò)管理過(guò)于復(fù)雜。 IP與ATM都是發(fā)展前景良好的技術(shù)，但它們?cè)诟髯缘陌l(fā)展過(guò)程中都遇到一些問(wèn)題。如果把這兩項(xiàng)技術(shù)結(jié)合起來(lái)，即將IP路由靈活性和ATM交換高速性結(jié)合起來(lái)，既可以充分利用ATM網(wǎng)絡(luò)的資源優(yōu)勢(shì)，又可以解決IP網(wǎng)絡(luò)發(fā)展中遇到的問(wèn)題，進(jìn)一步推動(dòng)通信業(yè)務(wù)的發(fā)展。實(shí)現(xiàn)IP與ATM結(jié)合主要有重疊方式和集成方式。重疊模型需要定義兩套地址、兩套選路協(xié)議和兩套管理維護(hù)功能。集成模型只需要使用IP地址和IP選路協(xié)議。 當(dāng)前互聯(lián)網(wǎng)使用較多的是IPv4協(xié)議，但隨著網(wǎng)絡(luò)的發(fā)展，IPv4協(xié)議存在一系列問(wèn)題，解決方案是用IPv6替代IPv4。IPv6具有充足的地址資源，使用更小的路由表，增加了增強(qiáng)的組播，加入了自動(dòng)配置，具有更高的安全性，提供較高的網(wǎng)絡(luò)服務(wù)質(zhì)量，從而IPv6更好實(shí)現(xiàn)OAM(Operation、Administration andMaintenance,操作、管理和維護(hù))。 本文所做的研究主要有以下幾個(gè)方面：學(xué)習(xí)并研究IP與ATM結(jié)合技術(shù)及IPv4向IPv6過(guò)渡的相關(guān)技術(shù)；分析研究IP模型、ATM模型及IP與ATM集成模型；通過(guò)三種主流過(guò)渡技術(shù)并以隧道技術(shù)為重點(diǎn)分別研究OAM功能實(shí)現(xiàn)；對(duì)基于6RD隧道技術(shù)進(jìn)行組網(wǎng)實(shí)驗(yàn)與研究，簡(jiǎn)化網(wǎng)絡(luò)操作及監(jiān)測(cè)網(wǎng)絡(luò)性能。
[Abstract]:With the rapid development of information technology, people have entered the information age.The Internet, which is mainly developed by computer, mainly uses IP switching technology based on packet transfer mode. IP technology is widely used, simple technology, good expansibility, flexible routing, easy to realize the interconnection of heterogeneous networks.Using connectionless technology, it is suitable for the communication of non-real time service, but the shortcoming is that the bandwidth is limited and the quality of service can not be guaranteed.With the popularity of broadband real-time services in people's daily life, the traditional IP network can not adapt to the development of future communications.The core of the broadband integrated service digital network (BISDN), which is mainly developed by telecommunication, is the ATM switching technology. The technology is based on the packet transfer mode and integrates the advantages of the circuit transmission mode.ATM technology adopts asynchronous time division multiplexing, realizes dynamic bandwidth allocation, adapts to any rate of service, uses connection-oriented working mode, exchanges quickly, and guarantees quality of service.The drawback is that network management is too complex.Both IP and ATM are promising technologies, but they all encounter some problems in their development.If we combine these two technologies, that is, the flexibility of IP routing and the high speed of ATM switching, we can not only make full use of the resource advantage of ATM network, but also solve the problems encountered in the development of IP network.To further promote the development of communications services.The combination of IP and ATM mainly includes overlap mode and integration mode.The overlapping model needs to define two sets of addresses, two sets of routing protocols and two sets of management and maintenance functions.The integration model only needs IP address and IP routing protocol.At present, IPv4 protocol is widely used in the Internet, but with the development of network, there are a series of problems in IPv4 protocol. The solution is to use IPv6 instead of IPv4.IPv6 to have sufficient address resources, to use smaller routing table, and to add enhanced multicast.Add automatic configuration, with higher security, provide higher network quality of service, thus IPv6 better implementation of OAM Operation Administration and maintenance, operation, management and maintenance.The research in this paper mainly includes the following aspects: study and study the technology of IP and ATM combination and the technology of transition from IPv4 to IPv6, analyze and study the IP model and the integration model of IP and ATM;Through three kinds of mainstream transition technology and focusing on the tunnel technology, the realization of OAM function is studied, and the network construction experiment and research based on 6RD tunnel technology are carried out to simplify the network operation and monitor the network performance.
