感谢大佬建议，不更了，晚点删库跑路，反正起初是自用

[chika0801]

VPS是DD的Debian11 Linux debian 5.10.0-26-amd64 #1 SMP Debian 5.10.197-1 (2023-09-29) x86_64 GNU/Linux

使用 bash <(curl -fsSL https://tcp.hy2.sh/) 安装好 tcp-brutal

编译sing-box（版本 Revision: c34556759c606e2de2a36293b4e7159289ccbac6）

服务端配置

{
    "inbounds": [
        {
            "type": "vless",
            "listen": "::",
            "listen_port": 443,
            "users": [
                {
                    "uuid": "chika",
                    "flow": ""
                }
            ],
            "tls": {
                "enabled": true,
                "certificate_path": "/root/fullchain.cer",
                "key_path": "/root/private.key"
            },
            "multiplex": {
                "enabled": true,
                "padding": false,
                "brutal": { // experimental
                    "enabled": true,
                    "up_mbps": 50,
                    "down_mbps": 20
                }
            }
        }
    ],
    "outbounds": [
        {
            "type": "direct"
        }
    ]
}

客户端出站部分配置

        {
            "tag": "proxy",
            "type": "vless",
            "server": "VPS的IP",
            "server_port": 443,
            "uuid": "chika",
            "flow": "",
            "tls": {
                "enabled": true,
                "server_name": "loveliveXXX.top",
                "utls": {
                    "enabled": true,
                    "fingerprint": "chrome"
                }
             },
            "packet_encoding": "xudp",
            "multiplex": {
                "enabled": true,
                "protocol": "h2mux",
                "max_connections": 4,
                "min_streams": 4,
                "padding": false
            }
        },

客户端访问speedtest.net测速，发现 "up_mbps": 50, 实际没有生效。我就放弃了。

[chika0801]

今天测试发现是 客户端出站部分配置 中

            "multiplex": {
                "enabled": true,
                "protocol": "h2mux",
                "max_connections": 4,
                "min_streams": 4,
                "padding": false
            }

改为

            "multiplex": {
                "enabled": true,
                "protocol": "h2mux",
                "max_connections": 4,
                "min_streams": 4,
                "padding": false,
                "brutal": {
                    "enabled": true,
                    "up_mbps": 50,
                    "down_mbps": 500
                }
            }

为什么回复您时，我没有加？我在开始测试时，用当时代码编译后的文件，客户端加了brutal报错无法启动，删除才能启动。

现在，客户端是win11，必须要有 brutal 字段参数，enabled为true，up_mbps和down_mbps随便填，肯定不会有效。

此时服务端配置中的 up_mbps 体现在客户端测速时的下行速率。客户端上行是你本地上行的速率。

已更新了readme

[tobyxdd]

Max connections 是不是应该设置为 1？否则会有多个连接吗 我也不是很清楚 singbox 这块

[chika0801]

另外需要注意的是，sockopt 设置的是每个连接的速度。这意味着其只适用于支持多路复用（mux）的协议，因为多路复用让客户端可以将所有代理连接整合到一个 TCP 连接中传输。 对于需要为每个代理连接单独建立连接的协议，当同时有多个连接活跃时，使用 TCP Brutal 会导致总发送速率超过所设置的上限。

我当时看到你这段话，没理解到。经你这样提醒，我也去看了下 Max connections 参数文档的解释。我认同你的看法。不过我不是专业的，这问题我不能肯定。也许哪天sing-box群有人提问和回答。

我先将readme中的内容改了。

[chika0801]

"max_connections": 4,
"min_streams": 4,

我昨天测试时 max_connections 4，服务端上行限制是填10，客户端win11，浏览器测speedtest网页版，下行结果就是在10以内并没超，有空我再实操研究一下。看代码和理论方面我不会（懂）。

update:复测的结果同上。

Configuration with brutal still uses normal tun? How to determine vps speed and set appropriate parameters

"This parameter is used in server-side configuration.

Typically, your server configuration does not use the 'tun' mode.

Regarding the value in the server configuration, in general scenarios, I believe a good range is around 100Mbps or smaller."

[Ley-VN]

I mean the client. Still using your tun configuration, right?

[chika0801]

I mean the client. Still using your tun configuration, right?

There is no correlation between the client configuration file about it and whether you use tun mode in your inbound configuration.
The client configuration corresponds to the outbound part, which requires those parameter contents shown in the example to take effect.
If your client is a linux system and has its kernel module installed, then the upstream rate (as opposed to the server which is the downstream rate of the server) filled in your client configuration parameters will take effect. But usually the client's uplink rate is not a priority. In mainland China, the network state, is the need for the client's downlink speed is good. (i.e. server-side uplink speed, so you just need to linux system on the server side, and installed its kernel module, it will take effect)

I can't help you with this information you have. You should rely on yourself to be self aware of some basics and try them out. This kind of hand-holding beginners and answering questions try is usually not liked by authors.

@tobyxdd

请教一下，我通过这个表格展示信息

	Multiplex	UDP relay mode	拥塞控制算法
Hysteria	自带		Brutal
Hysteria2	自带		Brutal / BBR
TUIC	自带	native / quic / udp_over_stream	BBR

Hysteria 1 / 2 在 UDP relay mode 中，填写什么单词比较恰当一点了？

都是 native

[chika0801]

这个问题我在群里反应过了，目前TCP-brutal里的mux调不了connection，默认只能1

你猜 hy 有几个 quic 连接

也是1个

我是想充分利用下TCP mux，可开多个TCP隧道，这样就不至于all in boom。（TCP没有连接迁移

那你帮 hy 实现一下在多个 TCP 连接之间共享一个网速？

不要想当然了

不能多个TCP隧道多个独立拥塞控制吗

设置网速一共是 100M，多个怎么独立控制

这种问题怎么从你嘴巴里说出来

是我无知了，大佬别生气

这是群友转的内容。看后我也认为在sing-box中，无论用户把 "max_connections": 4, 这里填几，实际效果是1。也许大佬你有空可以看看sing-box中相关的代码。
