Token bucket
open-in-new
<p>The token bucket is an <a href="/facts/Algorithm/fnl5NmRt">algorithm</a> used in <a href="/facts/Packet-switched/olDlDP1R">packet-switched</a> and <a href="/facts/Telecommunications_network/NFCX0STS">telecommunications networks</a>. It can be used to check that <a href="/facts/Data_transmission/1yAhaANd">data transmissions</a>, in the form of <a href="/facts/Network_packet/xCYf8SJu">packets</a>, conform to defined limits on <a href="/facts/Bandwidth_(computing)/lY6Tb4gX">bandwidth</a> and <a href="/facts/Burst_transmission/ep9vYM2N">burstiness</a> (a measure of the unevenness or variations in the <a href="/facts/Network_traffic_measurement/okrhK83A">traffic</a> flow). It can also be used as a <a href="/facts/Scheduling_algorithm/XptmcM1a">scheduling algorithm</a> to determine the timing of transmissions that will comply with the limits set for the bandwidth and burstiness: see <a href="/facts/Network_scheduler/7URA71LE">network scheduler</a>. </p>
