Abstract

The present invention provides a speed-limiting method and a device. The method is applied to a switch. The switch includes a timer. The method comprises the steps of adding a token into a token bucket through the timing triggering condition of the timer or the input triggering condition of data packets; obtaining the trigger delta time according to the latest triggering time and the current time;according to the trigger delta time and a preset unit token generation time, calculating to obtain the number of required tokens; and adding tokens of the required number into the token bucket. Therefore, tokens are added into the token bucket through the timing triggering condition of the timer or the input triggering condition of data packets. As a result, the switch cannot only meet the committed information rate requirements, but also the periodic network speed fluctuation condition can be avoided.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular, to a speed limiting method and device. Background technique [0002] As a computer connection and data interaction device, a switch needs to provide more network management functions in addition to basic data communication functions, such as Qos (Quality of Service, quality of service), switch port speed limit, etc. Therefore, the performance of the switch directly affects the overall network speed of the network in which it is installed. [0003] The switch uses the token bucket algorithm to limit the speed. In a large switch system, due to the large number of ports, the refresh cycle of the token bucket is relatively long. If the traffic of the port at the same time exceeds the speed limit setting, especially when the amount of data is relatively large, the token will be used up quickly at the beginning of the refresh cycle, and the data communication will be peri...
