【摘要】：随着信息技术的高速发展，人们已经快速进入了信息时代。以计算机为主开发的因特网（Internet），主要采用的是以分组传送模式为基础的IP交换技术。IP技术应用广泛，技术简单，可扩展性好，路由灵活，易于实现异种网络的互联，采用无连接技术，适于非实时业务的通信，缺点是带宽资源有限、无法保证服务质量。随着宽带实时性业务在人们日常生活中的普及，传统IP网络无法适应未来通信的发展。以电信为主开发的宽带综合业务数字网（B-ISDN），其核心是ATM交换技术。ATM技术是以分组传送模式为基础并融合了电路传送模式的优点发展而来，兼具分组传送模式和电路传送模式的优点。ATM技术采用异步时分复用方式，实现了动态分配带宽，可适应任意速率的业务，，采用面向连接的工作方式，交换快速，保证服务质量，缺点是网络管理过于复杂。 IP与ATM都是发展前景良好的技术，但它们在各自的发展过程中都遇到一些问题。如果把这两项技术结合起来，即将IP路由灵活性和ATM交换高速性结合起来，既可以充分利用ATM网络的资源优势，又可以解决IP网络发展中遇到的问题，进一步推动通信业务的发展。实现IP与ATM结合主要有重叠方式和集成方式。重叠模型需要定义两套地址、两套选路协议和两套管理维护功能。集成模型只需要使用IP地址和IP选路协议。当前互联网使用较多的是IPv4协议，但随着网络的发展，IPv4协议存在一系列问题，解决方案是用IPv6替代IPv4。IPv6具有充足的地址资源，使用更小的路由表，增加了增强的组播，加入了自动配置，具有更高的安全性，提供较高的网络服务质量，从而IPv6更好实现OAM(Operation、Administration andMaintenance,操作、管理和维护)。本文所做的研究主要有以下几个方面：学习并研究IP与ATM结合技术及IPv4向IPv6过渡的相关技术；分析研究IP模型、ATM模型及IP与ATM集成模型；通过三种主流过渡技术并以隧道技术为重点分别研究OAM功能实现；对基于6RD隧道技术进行组网实验与研究，简化网络操作及监测网络性能。
[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.
