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...
令牌桶算法(token bucket algorithm) 在实施QOS策略时,可以将用户的数据限制在特定的带宽,当用户的流量超过额定带宽时,超过的带宽将采取其它方式来处理。要衡量流量是否超过额定的带宽,网络设备并不是采用单纯的数字加减法来决定的,也就是说,比如带宽为100K,而用户发来的流量为110K,网络设备并... ...
“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…
令牌桶算法(token bucket algorithm) 限流 http://blog.csdn.net/sunnyyoona/article/details/51228456 今天观看QCon大会讲述了阿里线上管控体系,其中主要使用了令牌桶算法来实现限流的目的。表示非常好奇,故此学习一下什么是令牌桶算法。 1. 简介 令牌桶算法最初来源于计算机网络。在网络传输数据时,为了防止网络拥塞,...

基于漏桶(Leaky bucket)与令牌桶(Token bucket)算法的流量控制 Congestion Control Algorithm,这是TCP里的一个专业术语,拥塞控制算法。说的也是流量控制类似的事。 老规矩,直接上图。 先看看漏桶(Leaky bucket) 再看看令牌桶(Token bucket) Guava官方文档-RateLimiter类 漏桶(Leaky bucket)与令... ...
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 respectively. The single-rate-two-bucket ...
