摘要
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 .
This paper analysi s IPs limits in supproting QoS, describes the basic principles of all modes of merging of IP with ATM and analyzes their merits, drawbacks and relationships s ystematically. The analysis show that MPLS has merits of QoS class control, traf fic control, fast self-healing, label merging, scalability and ability to be ba sed on several physical networks, etc., so it is the most promising mode. These analyses and conclusions provide the technological basis and new ideas for furth er studying the technologies of merging of IP with ATM.
