Unknown network bitstream identification is the foundation for managing the relevant network and it can also support the further study on network countermeasures techniques.First, the main issues of unknown network bitstream identification such as encrypted and unencrypted bitstream identification,characteristic parameters mining of bitstreams,bitstreams clustering, frequent sequences mining and protocol format analysis are analyzed.Then, according to the internal relations of these issues, a multilevel scheme for unknown network bitstream identification is proposed,and the corresponding schemes are also provided to specific issues. Finally,while the relevant experimental results are presented, future research directions are discussed.The related research results have significance as reference for conducting further research on unknown network bitstream identification.
