PonderTalk网络策略模态冲突检测系统的研究
|
摘要
随着计算机网络异构化程度加剧,策略冲突已成为制约基于策略的网络管理(PBNM)技术实际应用的瓶颈。策略在描述上的不一致是导致策略冲突的主要原因之一,这类冲突被称为模态冲突。文章基于Pon-derTalk网络策略,针对模态冲突的不同类型提出检测算法,并将其整合为冲突检测系统。实验证明该系统是有效、可行的。
With the increasing degree of computer network isomerization,policy conflict has become the bottleneck of the practical application of Policy Based Network Management(PBNM) technology.The inconsistencies in the policy specification is one of the most important reasons that lead to policy conflict,called modality conflict.This paper proposed conflict detection algorithms according to different types of modality conflict based on PonderTalk network policy,then integrated them to a conflict detection system.Experiments show that the system is effective and feasible.
