As the network uses, and especially the number of internet users, increases rapidly, an efficient system for managing large network traffic datasets becomes an important issue. Although there are several network traffic analysis tools such as tcpdump, Ethereal, and other applications, these tools have weaknesses: limited size of files, command line execution, large memory and huge computational power requirement, and complications. In addition to these scalability limitations, both tcpdump and Ethereal have a security issue. Files captured by these tools keep all the packet information such as IP addresses, port numbers, and packet sizes.
