GENETIC ALGORITHM OPTIMIZED PACKET FILTERING

n our research, we present a method to optimize packet filtering by genetic
algorithm. Packet filtering in our work consists of packet capturing and firewall rules
reordering. Genetic algorithm is used to automate rules reordering and the discovery
of optimal combination of packet capture configuration, in the framework of
PF_RING platform and rules ordering. Our method has been tested in different sizes
of network traffic load. Genetic Algorithm evolves configuration based on the
recorded throughput rates; the higher the throughput the better the solution. Results
obtained indicate the effectiveness ofthe approach.
