分析了IP支持QoS的局限性 ;简述了各种IP与ATM融合技术的基本原理 ;系统地综合分析了各种融合技术的优缺点及相互区别与联系 .分析结果表明 :IP与ATM融合技术为解决路由器带宽问题和IPQoS问题提供了一条有效途径 ;MPLS具有QoS级别控制、业务流控制、快速自愈恢复、标记归并、良好的可扩展性以及可基于多种物理网络等诸多优点 ,因而应是最有希望的IP与ATM融合技术 .这些分析和结论为进一步研究IP与ATM融合技术提供了技术基础并开辟了新的思路 .
Analyzes the limitations of IP supporting QoS, briefly describes the basic principles of various IP and ATM convergence technologies, systematically and comprehensively analyzes the advantages, disadvantages and mutual differences of various fusion technologies, and analyzes the results.The results show that the IP and ATM convergence technologies It provides an effective way to solve the problem of router bandwidth and IPQoS. MPLS has many advantages such as QoS level control, traffic flow control, fast self-recovery, mark merge, good scalability and many kinds of physical networks Is the most promising IP and ATM convergence technology.These analyzes and conclusions provide the technical basis and open up new ideas for further research on IP and ATM convergence technologies.
