(57) Abstract: Disclosed in the present invention are a meth-od and device for traffic policing based on a token bucket,and the method includes: acquiring a length value of a cur-rently received message and a rate-limiting parameter index;obtaining a new message length value by adding the lengthvalue mantissa of a previously received message to the lengthvalue of the currently received message; according to a presetcomputation rule and on the basis of the new message lengthvalue, acquiring a new message mantissa and the actuallength value of the current message for which rate-limiting is

required; acquiring a rate-limiting result according to the ac-tual length value of the current message for which rate-limit-

ing is required and the corresponding rate-limiting paramet-ers in the rate-limiting parameter index; performing rate-lim-iting processing on the currently received message accordingto the rate-limiting result and a preset rate-limiting condition,and taking the new message mantissa or the length valuemantissa of the previously received message as the lengthvalue mantissa of the currently received message. By thepresent invention, rate-limiting precision can be improved.
