Abstract:Contra-posing the deficiencies of many current mainstream methods which are restricted in sharing broadband, we design an access driver of restriction of Broadband Sharing. In the access-user's system, we install a low-level driver, through which to establish a special point to point channel method to bind the access drivers to the user's system. The driver does not only limit the user to use broadband router, it also limits the behavior that user to uninstall the access drivers to startup the proxy server. This drivers use the data property method to discriminate user who are using proxy server software to share broadband. These have some reference value in practical application.
