Packet filtering using BDD is the one of the major contemporary firewall design techniques. An important design goal is to arrive at the decision at the packet only. Implementation of such packet filter using Binary Decision Diagram (BDD) gives more advantages in terms of memory usage and look up time as compare to other packet filter firewall technique. List-based packet filter has to prove the best with rules promotion method, but considerably lacks its efficiency when compared to BDD-based approach.
