Abstract:

Due to the different needs of different users, resource limitation of system and other reasons in the policy based network management system, these reasons led to conflict between policies, and system could not play a normal function. We proposed a conflict detection algorithm based on predicate reasoning, which could be obtained the conflict relationship between strategies by means of the trigger condition and the action effect of the predicate expression strategy. Compared with the traditional methods, this method has good flexibility and extensibility.

Key words:  policy based network management, predicate reasoning; conflict detection
