DiffServ体系带宽代理消息机制的安全性研究

Security Mechanism of Bandwidth Broker Signaling in DiffServ Architecture

探讨了使用DiffServQoS架构的IP网络内资源管理的带宽代理BB(BandwidthBroker)机制以及BB使用的消息机制的安全性问题,提出了两种可用于实现消息机制安全性的方案,并给出了具体实现方法的建议。

DiffServ architecture is a recommended framework to implement Quality of Service(QoS) in IP network.Bandwidth Broker(BB) is an effective mechanism in managing recourse and in engineering traffic in a Diffserv network.To function,a BB must communicate with routers in its trust region and BBs in other DiffServ regions.These communications are essentially to be protected and authenticated.Two security mechanism schemes are presented with suggestions in implementation.
