Abstract

The use of Application layer packet classifier and optimization of bandwidth towards QoS in Linux using netfilter, iproute2 and layer-7 Filter. As seen in the statistics the huge amount of data flows through the network, so it is necessity to apply packet-filtering rules in order to control the traffic and add firewall rules. Some services are inherently insecure and impossible to secure on individual hosts. Packet filtering tools can help you segment and contain parts of your network to increase security. A packet filtering tools can help you enforce your network security policies by selectively allowing network services. Because a packet filtering tools must examine all inbound/outbound network traffic, it can help you log network activity. We are looking at packet filtering tools like Netfilters and iproute2, who examine the IP packets for filtering and using the queuing disciplines for traffic control.
