“CAKE (Common Applications Kept Enhanced) is a shaping queue discipline which uses both AQM and FQ. It combines COBALT, which is an AQM algorithm combining Codel and BLUE, a shaper which operates in deficit mode, and a variant of DRR for flow isolation.
“Proportional Integral controller-Enhanced (PIE) is a control theoretic active queue management scheme. It is based on the proportional integral controller but aims to control delay.
“Proportional Integral controller-Enhanced (PIE) 是一种控制理论主动队列管理方案。它基于比例积分控制器,但旨在控制延迟。
主要设计目标是
低延迟控制
链路利用率高
简单实现
保证稳定性和快速响应”
FQ-PIE
FQ-PIE (Flow Queuing with Proportional Integral controller Enhanced) is a queuing discipline that combines Flow Queuing with the PIE AQM scheme. FQ-PIE uses a Jenkins hash function to classify incoming packets into different flows and is used to provide a fair share of the bandwidth to all the flows using the qdisc. Each such flow is managed by the PIE algorithm.
FQ-PIE(Flow Queuing with Proportional Integral controller Enhanced)是一种将流队列与 PIE AQM 方案相结合的排队规则。 FQ-PIE 使用 Jenkins 哈希函数将传入的数据包分类到不同的流中,并用于为使用 qdisc 的所有流提供公平的带宽份额。每个这样的流都由 PIE 算法管理。
