Performance Analysis of Range Algorithm

The need for network security will become more urgent over time. Not only are cybercriminals constantly inventing new ways to steal electronic information, they are getting more nefarious in their use of it. An effective solution for many businesses is the firewall, which monitors and regulates traffic flow between public and private network environments to thwart attacks and prevent the entry of hostile code. Firewall ACLs can contain inconsistencies. There is an inconsistency if different actions can be taken on the same flow of traffic, depending on the ordering of the rules. Many approaches to solve inconsistency and redundancy problems last approach called range algorithm. In this paper analysis performance of the range algorithm will introduce due to range, time processing, CPU utilization, number of rules and accuracy.
