Overview

Package quic defines functions to listen and dial quic, with some customizable congestion settings.

quic的包装太简单了, 直接参考 https://github.com/lucas-clemente/quic-go/blob/master/example/echo/echo.go

Hysteria Brutal Congestion Control

这里我们 还选择性 使用 hysteria的 brutal阻控. 见 https://github.com/tobyxdd/quic-go 中 toby的 *-mod 分支, 里面会多一个 congestion 文件夹.

我们这里利用其阻控，但是没有使用hysteria的通知速率和 auth的 数据头，也就是说我们这里是纯quic协议的情况下使用了hysteria的优点。

我们要是以后不使用hysteria的话，只需删掉 useHysteria 里的代码, 删掉 pacer.go/brutal.go, 并删掉 go.mod中的replace部分. 然后proxy.go里的 相关配置部分也要删掉 在 prepareTLS_for* 函数中 的相关配置 即可.

Imperfect Package

引用的 lucas-clemente/quic-go 包 是不完美的，它对阻塞控制支持不好，而且cpu占用率高。以后有更好的包的话要及时切换到好包。

我在macm1里实测，内网单机极速测速的情况下，本来tcp的vlesss能达到3000mbps的速度，到了vless+quic就只能达到 1333mbps左右。

实际上就是因为quic-go包占用cpu太猛了，导致cpu占用率达到100%瓶颈，所以速度无法进一步提高。

	Default_Server_maxStreamCountInOneConn = 4 //一个 Connection 中 stream越多, 性能越低, 因此我们这里限制为4

Functions

func CloseConn 

func CloseConn(conn any)

func ListenInitialLayers 

func ListenInitialLayers(addr string, tlsConf tls.Config, arg arguments) (newConnChan chan net.Conn, returnCloser io.Closer)

non-blocking

func SniffQUIC added in v1.2.2 

func SniffQUIC(b []byte) (sni string)

来自v2ray, 实际上就是先嗅探quic，之后再嗅探tls层。也就是说quic握手包是套在tls握手包外面的。
