Simulated Testing and Comparison of Algorithms for Packet Classification

After investigating the variety of algorithms based on tries structure and computational geometry, the software testing platform for their performance evaluation was implemented. The platform consists of network traffic simulation, algorithms and output parameters statistics. With the main performance curves, including time complexity curves and space complexity curves presented in the paper, the behaviors of algorithms can be recognized deeply. This is necessary as a good starting point to do further research on the new algorithms for packet classification and it is also possible to satisfy the most current application requirements by the combination of the present algorithms.
