Embodiment Construction

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and embodiments.

[0020] see figure 1 , a token issuance method provided by an embodiment of the present invention, comprising:

[0021] S11, setting a main issuing module responsible for issuing global tokens.

[0022] Among them, the main issuance module can be undertaken by the token issuance module on the service board with the smallest slot, or by a dedicated service board.

[0023] S12. Set up respective token buckets on each service board that needs to uniformly perform traffic measurement.

[0024] Separate token buckets are set on each service board that needs to perform traffic measurement uniformly, but the token buckets of each service board do not issue tokens independently.

[0025] S13. The main issuing module uniformly issues tokens to the token buckets on each of the service boards in a message ring manner.

Abstract

The embodiment of the invention provides a token issuing method and a token issuing system, which aim to solve the problem that a conventional token bucket cannot perform unified measurement on the traffic of a group of interfaces distributed on different service boards. The method comprises the following steps of: setting a main issuing module used for global token issuance; and setting own token buckets on each service board requiring unified traffic measurement, and issuing tokens to the token buckets on each service board in form of message loop in a unified way by using the main issuing module. The token issuing method and the token issuing system provided by the embodiment of the invention can be applied to switch or router products in the field of data communication as well as data gateway products in the field of wireless technologies.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a token issuing method and system. Background technique [0002] The token bucket (Token Bucket) is a common traffic measurement technology, which is often used to limit and shape the traffic of the service board, and can also measure the traffic rate. Its working principle is that the token bucket puts tokens into the bucket according to the speed set by the user. When the number of tokens in the bucket exceeds the capacity of the bucket, the number of tokens will not increase. When a message arrives, if there are enough tokens in the token bucket to send the message, the message will pass directly and continue to be sent, and the amount of tokens in the token bucket will be reduced accordingly according to the length of the message ; If the number of tokens in the token bucket is insufficient or empty, the packets that cannot get enough forwarding tokens will...
