  • Method and apparatus for organizing, storing and evaluating access control lists
    Patent number: 6651096
    Abstract: The invention relates to a method and apparatus for efficiently organizing, storing and evaluating access control lists (ACLs) for use by an intermediate network device of a computer network. The intermediate network device includes an ACL converter which, in turn, includes a boolean transformation engine that is operatively coupled to a boolean manipulation engine. The boolean transformation engine is configured to access the ACLs in first format and to translate them into a first boolean representation, such as binary decision diagram (BDD) format. The boolean manipulation engine is configured to perform one or more operations on the ACLs specified for a given interface, including a merge operation, so as to generate a single, unified ACL for the given interface. In order to resolve possibly conflicting actions output by the multiple ACLs, the ACL converter may utilize one or more predefined conflict resolution tables during the merging process.
