摘要
由于宽带和多媒体技术的不断发展,基于Policy系统实现对网络服务质量的监管,得到越来越多的研究与应用;但是它对服务质量的安全性的监管还不能令人满意,这也对其进一步应用与实施提出了严峻挑战。在支持RSVP的Policy系统基础上,本文提出通过增加支持RSVP安全性的规则实现其安全性,并且详细给出其设计原则以及这类规则的结构和内容,并论述了其在Policy系统中关键性设备——PEP、PDP的具体实现。
With the increasing development of broadband and multimedia technology, the implementation of IP-QoS based on policy system is inevitable. But the security in IP-QoS network is insufficiently supported in the policy system. It is a great challenge for the future policy system implementation and deployment. In this article, the authors present a solution, which realize the security in RSVP network by defining reasonable security QoS-policy rules(SQPR) in Policy system . The detail of SQPR for QoS security is given. Finally, the design and realization of policy system for RSVP security is presented.
