摘要：Firewalls are the devices that we are used to protect data. It might be configured to allow certain devices or applications to access our network. The Firewalls are termed as stateful devices. Traditional firewalls typically need to inspect each packet to ensure that it adheres to the policy that has been configured or not, and then perform the necessary action associated to that particular rule. There are various actions and they are typically allow, deny, or even NAT the packet. Many Personal Computer Operating Systems include software-based Firewalls to protect against threats from the public Internet. Existing Firewall Technologies such as Cisco PIX Firewalls and Checkpoint FireWall-1 provide various software tools that allowing firewalls as Clustered or Grouped and these Configured Firewalls will share their loads. The main objectives of these existing technologies are to improve the Resource Utilization along with performance and Security. But however these techniques fail to achieve higher performance while focusing resource utilization. This is one of the serious issues. To address this problem, our research work is developed and implemented an efficient Adaptive Scheduler, which improves the network performance in terms of Resource Utilization, Delay and Throughput. This work also introduced Firewall Reduction Policy, which reduces firewall rules without compromising Security. From our Experimental results, it is established that this proposed technique reduces the computational cost, which leads to higher performance.
