Firewall Session accelerate QoS, NAT and Routing using Decision Tree

Abstract

Firewall Security, Network address translation and QoS are precious objectives for network systems to be attained. Unfortunately, they are any conflict, while QoS tries to minimize processing delay, strong security protection requires more processing time and cause packet delay. This article is a step towards resolving this conflict by extending the firewall session table to accelerate NAT, QoS classification, and routing processing time while providing the same level of security protection. Decision Tree helps to reduce syntax in creating filter rule in packet session.
