Abstract:
A bandwidth sharing method for use on respective interstitial connections between on one side a plurality of users and on the other side a common data-link having a shared packet switching device, the method including performing the steps of:One) monitoring data-link directed bandwidth from each user; Two) maintaining a current sum of the monitored bandwidth; and Three) whenever the current sum exceeds a predetermined overall data-link bandwidth threshold, reducing current collective data-link directed bandwidth by a) for substantially each user, comparing the respective user's data-link directed bandwidth with a predetermined user data-link bandwidth threshold for the respective user; b) using an allocation function, selecting at least one user who is exceeding his predetermined user data-link bandwidth threshold, and c) for a predetermined time interval, cutting the connection between each selected at least one user and the shared switching device, so as to restore a current sum of the monitored bandwidth to be not greater than the predetermined overall data-link bandwidth thresholds, wherein performing at least one of the steps is done above a predetermined frequency.
