ABSTRACT:
A network access control device for deterministic recognition of application frames satisfying a set of predetermined rules comprises: means (205) for monitoring and interpretation of the application frames to recognize; means (201) for storing the predetermined rules; means (202) for compiling the predetermined rules in a direct access data structure; means (203) for storing the direct access data structure; and means (204) for comparing the application frames to be recognized with the direct access data structure, wherein the recognition is able to be performed on any frame component and the direct access data structure allows an access time substantially independent from the number of rules.
