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. WebFixed window algorithms can be implemented at the user-level or server-level. If it is implemented at user-level, then each user can make 100 requests per minute. If it is a server-level, then all the users can …
