1. A method, comprising:

  • receiving a set of traffic shaping parameters to shape a first stream of data of a plurality of streams of data by a traffic shaper, the set of traffic shaping parameters comprising a sustained rate, a sustained burst size, a peak rate, and a peak burst size;

    determining an adjusted maximum transmission rate from the set of traffic shaping parameters, wherein the adjusted maximum transmission rate is the maximum rate the traffic shaper can transmit the first stream of data;

    periodically adding a plurality of tokens to a sustained rate token bucket, wherein the number of the plurality of tokens added is based on the sustained rate and the sustained burst size;

    monitoring a current transmission rate the traffic shaper is transmitting the first stream of data;

    allowing transmission of parts of the stream of data if there are currently enough tokens in the sustained rate token bucket and based on a comparison of the current transmission rate of the stream of data and the adjusted maximum transmission rate.
