节点搭建系列(8)：如何不花钱提升你的节点速度？使用CF的免费CDN服务提升节点速度，bbr拥塞控制优化链路速度，CDN的原理、CF优选IP的原理，vless+ws+tls+web+cdn节点组合搭建

In this final episode of the node‑building series, the presenter explains how to boost node speed without spending money by using Cloudflare’s free CDN and BBR congestion control. The tutorial covers the principles of CDN, how to apply Cloudflare’s free CDN, the process of translating traffic through CDN, switching CDN servers, and the use of CDN’s optimal IP selection. It also discusses TLS and origin server settings after CDN integration, and demonstrates how to build a vless+ws+tls+web+cdn node. Additionally, the video explains TCP congestion control, enabling BBR, and the use of hysteria for speeding up subpar lines. The presenter concludes with thanks. 00:00 前言 01:07 使用x-ui搭建vless+ws 04:18 CDN的原理 07:14 CDN竟然是减速器？ 08:35 套用cloudflare免费CDN 11:50 利用CDN翻墙的原理 14:50 手动更换CDN服务器 18:21 CDN优选IP原理与使用 21:34 套用CDN之后TLS、回源相关知识 26:00 搭建vless+ws+tls+web+cdn 31:40 TCP拥塞控制的原理 37:43 启用BBR拥塞控制算法 39:43 hysteria提速垃圾线路原理 41:55 完结撒花、感谢大家
