Research on extensible policy transformation mechanism based on two-phase transformation

Policy transformation is one of the key problems to implement the policy management.An extensible policy transformation system structure is designed and a two-phase transformation idea is proposed.In phase one,according to the compiler principle source policies are transformed into the devices-independent medium policies though the lexical and syntax analysis by the policy compiler,and in phase two,artificial intelligence is used to create the policy assembling units and the medium policies are transformed into the executable devices-dependent target policies by the knowledge base.Through designing lexical base and policy knowledge base,extensible policy transformation is implemented,which enhances the flexible and operability of policy transformation.
