WebApr 12, 2024 · Fixed window counters. As a second approach, I considered fixed window counters. It’s a simple, memory-efficient algorithm that records the number of requests from a sender occurring in the rate … 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.
