What is Token Bucket? 令牌桶算法是用于计算机网络和电信中用于流量整形和速率限制的算法。它旨在控制系统在某种时间段内可以发送或接收的数据量,确保流量符合指定的速率。 让我们先从一个最简单的模型看起。 令牌桶背后的基本思想非常简单。当数据包到达时,Policer 将检查令牌桶中是否有足够的令牌,如果有,数据包将...
“人会爱上自己所知的事物,却更爱未知的事物。” -- 《火山挚恋》 上文说到Policer是一个通过令牌桶算法进行报文流量监控的组件,Policer经常进行令牌的消耗和补充。然而,在补充过程中,如果令牌桶中剩余的令牌…

默认情况下，如果KeyResolver没有找到一个key，那么请求将会被拒绝。你可以调整这种行为，通过设置spring.cloud.gateway.filter.request-rate-limiter.deny-empty-key (true or false) 和 spring.cloud.gateway.filter.request-rate-limiter.empty-key-status-code属性。Redis基于 Token Bucket Algorithm （令牌桶算法）...
Single-Rate-Two-Bucket Mechanism The single-rate-two-bucket mechanism uses the srTCM algorithm defined in RFC 2697 to measure traffic and marks packets green, yellow, or red based on the metering result. As shown in Figure 5-1, buckets C and E contain Tc and Te tokens respectivel...
The two rate three color marker (trTCM) algorithm determines traffic bursts based on the rate of packets. The token bucket algorithms mark packets red, yellow, or green based on the result of traffic metering. The system then processes the packets according to their marked color. The two afore...
