pixie's Introduction

pixie

尽力保持吞吐(有效带宽)的 TCP 发包算法,pixie 不是 “皮鞋”,而是 “捣蛋鬼”.

  • 算法细节:
    • pacing_rate = rate * (losses + acked)/(acked)
    • cwnd = rate * (losses + acked)/(acked) * rtt

安装

  • 安装内核头文件: apt install kernel-package
  • make
  • insmod ./tcp_pixie.ko
  • echo 200000000 >/sys/module/tcp_pixie/parameters/rate # 保 200MBps 吞吐

测试

  • iperf -s 端设置丢包:iptables -I INPUT -p tcp --dport 5001 -m statistic --mode random --probability 0.09 -j DROP
  • iperf -c x.x.x.x - i 1 -Z pixie
