The token bucket is an algorithm used in packet-switched and telecommunications networks. It can be used to check that data transmissions, in the form of packets, conform to defined limits on bandwidth and burstiness (a measure of the unevenness or variations in the traffic flow). It can also be used as a scheduling algorithm to determine the timing of transmissions that will comply with the limits set for the bandwidth and burstiness: see network scheduler. danza veracruzanaWebApr 11, 2024 · Fixed window: Fixed-window limits—such as 3,000 requests per hour or 10 requests per day—are easy to state, but they are subject to spikes at the edges of the window, as available quota resets.
