Assume your local network to your server is lossy. Just establish a VPN connection to your server with UDPspeeder + any UDP-based VPN, access your server via this VPN connection, then your connection quality will be significantly improved. With well-tuned parameters , you can easily reduce IP or UDP/ICMP packet-loss-rate to less than 0.01% . Besides reducing packet-loss-rate, UDPspeeder can also significantly improve your TCP latency and TCP single-thread download speed.

# 应用

|
||||
#### UDPspeeder + OpenVPN加速任何流量,也适用于其他VPN
|
||||

|
||||
|
||||
可以和BBR/锐速叠加,不过BBR/锐速部署在VPS上只对本地和VPS间的流量有效,对从本地和第三方服务器间的流量无效。
|
||||
|
||||
需要在服务端开启ipforward和NAT。在客户端改路由表(可以手动修改,也可以由OpenVPN的redirect-gateway选项自动加好)。

||||

||||

|
||||

||||
https://github.com/wangyu-/tinyFecVPN/
|
||||
|
||||
#### UDPspeeder + kcptun/finalspeed + $*** 同时加速tcp和udp流量
|
||||
如果你需要用加速的tcp看视频和下载文件,这样效果可能比没有BBR的UDPspeeder+vpn方案更好。另外,如果你需要玩游戏,但是嫌配VPN麻烦,也可以用这种方案。
|
||||

|
||||
|
||||
具体配置方法简介:
|
||||
|
||||
假设$\*\*\* server监听在在44.55.66.77的443端口(tcp和udp同时)。用kcptun把tcp 443映射到本地的tcp 1234;用UDPspeeder把udp 443的映射到本地的udp 1234。
|
||||
然后让$\*\*\* client 去连127.0.0.1:1234就可以了,tcp和udp都被加速了。完整命令:
|
||||
```
|
||||
run at server side:
|
||||
./kcp_server -l ":4000" -t "127.0.0.1:443" -mode fast2
|
||||
./speederv2 -s -l0.0.0.0:4001 -r127.0.0.1:443 -f20:10 -k "passwd"
|
||||
|
||||
run at client side:
|
||||
./kcp_client -l ":1234" -r "44.55.66.77:4000" -mode fast2
|
||||
./speederv2 -c -l0.0.0.0:1234 -r44.55.66.77:4001 -f20:10 -k "passwd"
|
||||
```
|
||||
|
||||
这就是全部的命令了。issue里有很多人困惑于怎么把tcp和udp流量"分开",其实很简单就可以做到。
|
||||
|
||||
如果只需要加速UDP,不需要加速TCP,可以把kcptun换成其他的任意端口转发方式,比如ncat/socat/ssh tunnel/iptables/[tinyPortMapper](https://github.com/wangyu-/tinyPortMapper/releases)。
|
||||
|
||||
如果你没有kcptun只有BBR/锐速的话,也可以把kcptun换成ncat/socat/ssh tunnel/iptables/[tinyPortMapper](https://github.com/wangyu-/tinyPortMapper/releases)。这样,TCP流量由锐速/BBR加速,UDP由UDPspeeder加速。
|
||||
|
||||
另外,即使你不想使用$\*\*\*的TCP功能,你也必须把$\*\*\*的TCP端口转发过来,否则无法使用UDP功能,这是socks5协议的工作方式决定的。($\*\*\*-redir方式不受此限制)
|
||||
|
||||
#### UDPspeeder + openvpn + $*** 混合方案,也适用于其他VPN
|
||||
也是我正在用的方案。优点是可以随时在vpn和$\*\*\*方案间快速切换。
|
||||
实际部署起来比图中看起来的还要简单。不需要改路由表,不需要写iptables规则和开启NAT,需要做的只是用openvpn分配的ip访问$*** server。
|
||||
|
||||

|
||||
|
||||
(也可以把图中的$*** server换成其他的socks5 server,这样就不需要$*** client了)
|
||||
|
||||
可以和BBR/锐速叠加,BBR/锐速只要部署在VPS上就有效。
|
||||
|
||||
也可以用[tinyFecVPN](https://github.com/wangyu-/tinyFecVPN/) + $\*\*\* ,配置起来更简单。
