METHOD AND SYSTEM FOR DYNAMIC RATE-LIMITING IN SWITCH
First Claim
1. A dynamic rate-limiting method used in a switch for switching packets from input ports to output ports, the method comprising:
- (a) adding traffic bandwidth values set in advance in active subscribers that are using the switch from among subscribers connected to the switch;
(b) comparing the added value with a range between a maximum bandwidth and a minimum bandwidth that are set in the switch; and
(c) according to a result of comparing, when the added values is smaller than the minimum bandwidth or larger than the maximum bandwidth set in the switch, increasing or decreasing the traffic bandwidths of the active subscribers set in advance so that the added value is within the range between the maximum bandwidth and minimum bandwidth.

Abstract
Provided is a dynamic rate-limiting method and apparatus used in a switch for switching packets from input ports to output ports, the method including: (a) adding traffic bandwidth values set in advance in active subscribers that are using the switch from among subscribers connected to the switch; (b) comparing the added value with a range between a maximum bandwidth and a minimum bandwidth that are set in the switch; and (c) according to a result of comparing, when the added values is smaller than the minimum bandwidth or larger than the maximum bandwidth set in the switch, increasing or decreasing the traffic bandwidths of the active subscribers set in advance so that the added value is within the range between the maximum bandwidth and minimum bandwidth. Accordingly, it is possible to automatically control the traffic bandwidths of subscribers that are currently using the switch.

7. A dynamic rate-limiting apparatus used in a switch for switching packets from input ports to output ports, the apparatus comprising:
-
a rate calculating unit adding all of traffic bandwidth values set in advance in active subscribers that are using the switch from among subscribers connected to the switch; a rate comparing unit comparing the added value with a range between a maximum bandwidth and a minimum bandwidth that are set in the switch; and a rate setting unit increasing or decreasing the traffic bandwidths of the active subscribers set in advance so that the added value is within the range between the maximum bandwidth and minimum bandwidth set in the switch when the added value is smaller than the minimum bandwidth or larger than the maximum bandwidth set in the switch according to a result of comparing. - View Dependent Claims (8, 9, 10, 11, 12)
