Abstract: For the congestion problems from campus network, this paper proposes a user interest modeling method based on behavior analysis, measures and calculates user’s interestingness of different applications with user participation time, researches the bandwidth management strategy combining with channel management technology on the basis of user’s interestingness. The implementation results show that this method can effectively improve user’s network satisfaction.

Key words: user’s behavior analysis, interestingness, interestingness model, bandwidth management strategy, channel bandwith
