Analogizing from transportation traffic system, the paper discusses some licenses and certifications which are issued to users based on security level checks. Gateways at the edge of the IP networks inspect the licenses and certifications and manage the transmission. The paper further describes image of IP network to achieve the proposal. In the end, the paper describes effectiveness of the introduction of the qualifying system and items to be studied in the future.
