可重构柔性网络中网络资源控制的冲突检测机制

A mechanism of detecting resources control conflicts in reconfigurable flexible networks

为了实现网络重构过程中的网络资源控制,减少因资源控制冲突引起的重构失败,提出了一种可重构柔性网络环境中的冲突检测机制。该机制考虑了重构策略的执行与资源状态间的关系,通过对资源重构机制建模获得重构策略执行间的时序关系,根据策略执行间的相互影响进行冲突检测。提出的冲突检测机制与传统检测机制相比减少了人工判断和控制的参与,扩大了资源冲突检测的范围。最后通过实例分析对检测机制的有效性进行了验证。

In order to achieve consistent resources control and reduce the times of failed networks reconfiguration, a novel conflicts detection mechanism is presented in recordigurable flexible networks. It models the resources control system by defining resources status and policy actions, and then detects policy conflicts by simulating policy enforcement. It solves the problem that traditional conflicts detection mechanisms add too much burden to the managers and could only be implemented to certain resources control mechanisms. Experiments verify that this mechanism has good perfonnance.
