The present disclosure relates to the field of communication technologies, in particular to a shared bandwidth speed-limiting method, device, and storage medium. The method for customer premise equipment comprises: adding a token into a token bucket of the customer premise equipment based on an initial bandwidth rate; and sending a statistical information report to a central controller every preset time interval, wherein the statistical information report represents a report reflecting a surplus or deficiency condition of tokens in the token bucket, and is configured to instruct the central controller to reallocate tokens of the customer premise equipment by a central token bucket. In embodiments, a token bucket algorithm is introduced to a distributed environment with a central controller, so that at least two pieces of customer premise equipment in distributed apparatuses can share a speed-limiting bandwidth, providing more flexible bandwidth subscription options and further improving the utilization of bandwidth resources.
