提供端到端QoS的带宽代理体系结构

Provision of End-to-end QoS Bandwidth Broker System Structure

随着Internet规模的不断增大,各种各样的网络服务争相涌现,IPQoS正成为业界关注和研究的热点。为集中管理和控制IP网络的带宽资源,引入了带宽代理(BB)体系结构。在深入研究TEQUILA项目成果的基础上,扩展了BB的体系结构,增加了域间交互、计费、安全管理和在线约束选路等功能,使之能够满足端到端的QoS需求。

With the growth of Internet scale,varieties of network services are e-merging.IP QoS is becoming hotspot of the concern and research in the in-dustry.To realize centralized manage-ment and control of bandwidth re-source of IP network,BB system archi-tecture is introduced.Based on the re-search result of TEQUILA project,BB system architecture is extended,func-tions of inter -domain exchange,billing,safety management and on-line constrained -based routing are added,which enables it to meet the require-ments of end-to-end QoS.
