目前使用的加权轮询叫做平滑的加权轮询(smooth weighted round-robin balancing),它和前者的区别是: 每7个请求对应的后端序列为 { a, a, b, a, c, a, a },转发给后端a的5个请求现在分散开来,不再是连续的。 摘录此算法的描述: On each peer selection we increase current_weight of each eligible ...
ngx_http_upstream_init_round_robin做的工作很简单: 指定请求的负载均衡初始化函数,用于初始化per request的负载均衡数据。 创建和初始化后端集群、备份集群。 ngx_int_t ngx_http_upstream_init_round_robin (ngx_conf_t *cf, ngx_http_upstream_srv_conf_t *us) { ngx_url_t u; ngx_uint_t...

Simulations are used to evaluate the performance of the proposed algorithm load-aware weighted round robin (LAWRR), and show that it reduces average delay and packet loss, as well as it improves average throughput compared with WRR. The effectiveness of LAWRR running under fixed buffer sizes is...
本文参考了Nginx的负载均衡 - 加权轮询 (Weighted Round Robin) 。 算法简介 有三个节点{a, b, c},他们的权重分别是{a=5, b=1, c=1}。发送7次请求,a会被分配5次,b会被分配1次,c会被分配1次。 一般的算法可能是: 1、轮训所有节点,找到一个最大权重节点; 2、选中的节点权重-1; 3、直到减到0,...
WRR:(Weighted Round Robin,简称WRR)加权循环调度算法。加权循环(WRR)所有业务队列服务,并且将优先权分配给较高优先级队列。在大多数情况下,相对低优先级,WRR将首先处理高优先级,但是当高优先级业务很多时,较低优先级的业务并没有被完全阻塞。加权循环调度算法WRR(Weighted Round Robin)是一种较强的队列调度算法,...
