## B1 · 联调基线（1-2 天，和 A 合作完成）
|
||||
|
||||
目标：拿到 H.264 版双机实测数据，作为一切优化的对照基线。
|
||||
|
||||
1. **HUD 扩展**：新增 丢包率(估算)/抖动(jitter)/帧间隔 p95 三项读数
|
||||
- 抖动 = 相邻帧 E2E 差值的绝对值 EMA；帧间隔 p95 用环形缓冲取 95 分位；
|
||||
- 码流异常计数（解码失败次数）也上 HUD，验证关键帧自愈是否生效。
|
||||
2. **测试脚本** `tools/bench.md`：固定三个场景各测 60s —— 静止桌面 / 播放视频 / 拖动窗口，记录 HUD 截图。
|
||||
3. **产出**：基线数据表填入本文件末尾。
|
||||
|
||||
## B2 · 码率自适应（3-4 天）
|
||||
|
||||
目标：弱网自动降码率保流畅，好网缓慢升码率提画质。
|
||||
|
||||
### 协议扩展（common/）
|
||||
|
||||
```rust
|
||||
/// B2 新增控制消息（流 2）
|
||||
RateReport {
|
||||
loss_permille: u16, // 接收端估算丢包率 ‰
|
||||
rtt_ms: u32, // 最近 RTT
|
||||
e2e_ms: u32, // 平滑后端到端延迟
|
||||
}
|
||||
```
|
||||
|
||||
viewer 每 2s 汇总一次发送（流 2 复用，无新增握手）。
|
||||
|
||||
### 控制算法（先简后精，AIMD 风格）
|
||||
|
||||
| 网络状态（连续 3 个周期） | 动作 |
|
||||
|---|---|
|
||||
| 丢包 > 8% 或 E2E > 400ms | 码率 ×0.6（下限 1Mbps），同时通知编码器降帧率到 20fps |
|
||||
| 丢包 3-8% | 码率 ×0.9 |
|
||||
| 丢包 < 1% 且 E2E < 150ms 持续 10s | 码率 +500Kbps 步进上探（上限 15Mbps） |
|
||||
|
||||
### agent 侧配合点（给 A 的接口需求）
|
||||
|
||||
- 需要运行时改码率的入口：优先查 openh264 crate 是否暴露 `SetOption(RC_PARAM)`；
|
||||
- 若 crate 不支持 → 方案 B：保留 encoder 实例但按新码率重建（重建成本 ~50ms，降码率不频繁，可接受）；
|
||||
- 降级到极限（1Mbps 仍丢包 >15%）→ 主动降分辨率 1080p→720p（A 实现，协议传 `ResChange` 通知，viewer 重配解码器与窗口尺寸）。
|
||||
|
||||
## B3 · P2P 打洞 + 信令 + 中继（1.5-2 周，核心里程碑）
|
||||
|
||||
目标：跨公网可用。三层结构：
|
||||
|
||||
```
|
||||
┌─────────┐ ①注册/交换地址(WebSocket) ┌──────────┐
|
||||
│ viewer │ ───────────────────────────→ │ 信令服务器 │
|
||||
└────┬────┘ └──────────┘
|
||||
│ ②拿到对方候选地址(IP:port×N) ↑
|
||||
│ ③a 直连(打洞) ──────────────────── agent 注册
|
||||
│ ③b 失败 → 走 TURN 中继
|
||||
```
|
||||
|
||||
### 信令服务器（B 主建，A 参与评审）
|
||||
|
||||
- 最小实现：单二进制 Rust + WebSocket（tokio-tungstenite），无数据库；
|
||||
- 消息：`Register{agent_id}` / `Connect{agent_id}` / `Answer{candidates, auth_code_hint}`；
|
||||
- agent 开机注册自身 ID（设备码），viewer 输对方 ID 发起；
|
||||
- 中立服务器，不碰媒体数据，带宽成本 ≈ 0。
|
||||
|
||||
### 候选地址与打洞
|
||||
|
||||
1. agent 侧收集候选：本机局域网地址、路由器公网映射（STUN 探测，自建 coturn 的 stun 或公共 stun）；
|
||||
2. 双方经信令交换候选后**同时**向对方发探测包（UDP 打洞，锥形 NAT 成功率高；对称 NAT 基本打不通）；
|
||||
3. 打通 → 直连（QUIC 直接到该地址）；打不通 → TURN 中继兜底。
|
||||
|
||||
### 中继方案（务实路线）
|
||||
|
||||
QUIC 本身没有标准 TURN 集成，两条路：
|
||||
- **路线一（推荐先做）**：自建中继服务 `relay` —— viewer 把 QUIC 包封装转发给 relay，relay 转给 agent（本质是应用层 TURN，复用信令服务器的部署）；
|
||||
- **路线二（二期）**：coturn + 手写 ICE-lite，仅在路线一性能不足时投入。
|
||||
|
||||
### 安全（随 B3 一起做，替代现在的跳过校验）
|
||||
|
||||
- 预共享验证码升级为 **PAKE（SPAKE2）**：验证码不落服务器、不落网络，双方推导会话密钥；
|
||||
- 信令只传地址候选，媒体端到端加密保持 QUIC TLS 不变。
|
||||
|
||||
## B4 · 多屏 + 文件传输（各 2-3 天，穿插做）
|
||||
|
||||
**多屏**：
|
||||
- 协议：`ScreenList{screens: Vec<{id, w, h}>}`（AuthOk 里带）、`SelectScreen{id}`；
|
||||
- agent 枚举 DXGI outputs（A 实现），viewer 加屏幕切换下拉；
|
||||
- 第二期再做"多屏同显"。
|
||||
|
||||
**文件传输**：
|
||||
- 首选走已有 QUIC 连接开独立双向流（不引入 aria2 依赖，部署简单）；
|
||||
- 协议：`FileOffer{name, size}` → `FileAccept` → 原始分块流（1MB 块 + 校验）；
|
||||
- viewer 做拖拽发送 + 保存对话框。
|

## 里程碑与分支规划
|
||||
|
||||
| 里程碑 | 分支 | 预估 | 验收标准 |
|
||||
|---|---|---|---|
|
||||
| B1 联调基线 | feature/hud-baseline | 1-2 天 | 三场景基线数据入库 |
|
||||
| B2 码率自适应 | feature/rate-adapt | 3-4 天 | 模拟弱网（clumsy/丢包工具）下自动降码率，画面不断流 |
|
||||
| B3 打洞+中继 | feature/p2p-relay | 1.5-2 周 | 两台跨公网机器通过 ID 互联；打洞失败自动走中继 |
|
||||
| B4 多屏/文件 | feature/screens-files | 3-5 天 | 多屏切换、拖拽传文件可用 |
|
||||
|
||||
顺序建议：B1 → B2 → B3 → B4（B3 是价值最大项，B4 可穿插）。
|
||||
|
||||
## 基线数据表（B1 完成后填写）

|

//! ② 下发同步打洞计划，让双方在同一绝对时刻开始发包。建连完成后信令与本次会话再无关系，

//! （见 [`PunchFailReason::user_hint`]），不允许让用户停在"连接中"。

# 双机测试基线脚本（B1）
|
||||
|
||||
每个场景测试 60 秒，记录 HUD 读数填入《B侧设计文档.md》末尾的基线数据表。
|
||||
|
||||
## 准备
|
||||
|
||||
- 两端都用最新 release：`agent.exe` + `viewer.exe`（同目录带 3 个 mingw DLL）
|
||||
- 被控机：`agent.exe --port 47800 --code 123456`
|
||||
- 主控机：`viewer.exe --addr <被控机IP> --port 47800 --code 123456`
|
||||
- 测试前确认：被控机亮屏有桌面；同一网络（记下是有线还是 WiFi 频段）
|
||||
|
||||
## 场景
|
||||
|
||||
| # | 场景 | 被控机操作 | 观察点 |
|
||||
|---|---|---|---|
|
||||
| 1 | 静止桌面 | 打开一个空白文档，不动 60s | FPS 应低（静止检测），E2E/JIT 应绿 |
|
||||
| 2 | 视频播放 | 全屏播放任意 1080p 视频 | 码率峰值、FPS、丢包（LOSS 行） |
|
||||
| 3 | 拖动窗口 | 持续快速拖动一个大窗口 60s | 最恶劣工况：E2E/P95/JIT 是否变红、DECFAIL 是否增长 |
|
||||
|
||||
## 记录方法
|
||||
|
||||
每个场景进行中截一张 HUD 图（Win+Shift+S 框选右上角），或肉眼逐行抄录：
|
||||
|
||||
```
|
||||
FPS= RTT= E2E= JIT= P95= LOSS= DECFAIL= RATE=
|
||||
```
|
||||
|
||||
## 附加记录
|
||||
|
||||
- 网络环境：有线 / WiFi 5GHz / WiFi 2.4GHz，信号强度
|
||||
- 被控机 CPU 占用（任务管理器，agent.exe 一行）
|
||||
- 编码器类型：当前 openh264 软编（A 侧换 NVENC 后需重测一轮对比）
|
||||
|
||||
## 注意
|
||||
|
||||
- LOSS 显示 `--` 表示第一个 Pong 还没回来或 Δsent=0（静止场景发送少，属正常）
|
||||
- DECFAIL 在连接建立初期可能有 1-2 次（等第一个关键帧），后续不应增长；持续增长 = 关键帧自愈有问题，报给 A

"""UDP 打洞探针 —— 两台不同网络的机器各跑一个，用来摸清你们线路的底牌。

回答四个问题：

1. 这条线路的 NAT 能不能打洞？
|

2. 要几轮才能打通？（轮数越少说明 NAT 越宽松）
|

3. 对方的源端口有没有被 NAT 改写？（判断是不是对称 NAT）
|

4. 有没有公网 IPv6？IPv6 直连通不通？

B 机（假设公网 2.3.4.5）:

IPv6（双方都有公网 v6 时）:

py punch_probe.py --peer [2408:8207:1234::1]:47800

先查自己的公网映射（走 STUN，不需要对方）:

----
|

- 两台机器必须**同时**启动，脚本靠「双方同时向对方发包」来穿透 NAT。

- 先各自查公网 IP（浏览器搜 "my ip" 或 --stun），再互相填。

- 只依赖 Python 标准库。

||||
> 状态：架构部分已定稿；第 2 章的「逆向需求清单」等同事的逆向资料回填。
|
||||
|
||||
---
|
||||
|
||||
## 0. 使用方式
|
||||
|
||||
| 角色 | 看哪几章 |
|
||||
|---|---|
|
||||
| A（被控侧） | §3.5 platform、§3.6 agent-core、§4 表中 agent 相关行 |
|
||||
| B（主控+协议） | §3.1–3.4、§3.7 viewer-core、§5 许可 |
|
||||
| 移动端（待补人） | §3.4 media（解码后端）、§3.8 apps |
|
||||
| 全员 | §2 逆向红线（踩了会出大事） |
|
||||
|
||||
---
|
||||
|
||||
## 1. 两条铁律
|
||||
|
||||
1. **架构由需求决定，不由参考项目决定。** 参考项目用来解决"这一块业界怎么做的"，不是用来决定"我们做成什么样"。
|
||||
2. **能抄的是算法和协议思路，抄不到的是平台集成和 UI。** 后者是体力活，任何参考项目都救不了（它们自己也是硬写的）。
|
||||
|
||||
---
|
||||
|
||||
## 2. 逆向资料的用法与红线
|
||||
|
||||
### 2.1 红线（务必转告同事）
|
||||
|
||||
| 可以做 | 不可以做 |
|
||||
|---|---|
|
||||
| 记录**功能清单、交互流程、界面布局** | 把反编译产物、反汇编清单提交进仓库 |
|
||||
| 记录**用户可见的错误提示、状态显示** | 逐字复制对方的 UI 文案、图标、素材 |
|
||||
| 推断**产品模型**（账号/设备/授权怎么设计） | 抄对方私有协议的具体编码（抄了也不能互通） |
|
||||
| 记录**网络行为的宏观特征**（是否中转、连接耗时） | 提取并移植对方的算法实现 |
|
||||
|
||||
**仓库里只提交"行为结论"，不提交"逆向产物"。** 建议逆向资料单独放一个**不纳入 git** 的目录（或内部网盘），文档里只写结论。这条不是洁癖——商用产品里出现竞品反编译代码是实打实的法律风险。
|
||||
|
||||
### 2.2 逆向需求清单（直接发给同事）
|
||||
|
||||
**A. 产品功能面（最重要，优先做）**
|
||||
|
||||
1. 主控端完整交互流程截图流：登录 → 设备列表 → 连接（输密码/免密）→ 会话中 → 断开
|
||||
2. 每个平台的功能矩阵：Win/Linux/Android/iOS 各有哪些功能、哪些缺失
|
||||
3. 会话中工具栏全清单：分辨率切换、多屏、文件传输、剪贴板、音频开关、画质/帧率档位、游戏模式
|
||||
4. 设置项全清单（分"被控设置"和"主控设置"两类）
|
||||
5. 错误提示文案全集 + 断线重连时的用户可见行为
|
||||
|
||||
**B. 身份与授权模型**
|
||||
|
||||
6. 设备 ID 的形式（长度/字符集）、在哪里查看、能否自定义
|
||||
7. 授权方式有几种：临时密码 / 固定密码 / 免密白名单 / 账号直接授权？默认是哪种
|
||||
8. 账号体系：是否必须登录、登录后设备列表怎么呈现、一台设备能否被多账号访问
|
||||
9. 被控端的"允许谁连"控制（黑名单/白名单/单次确认弹窗）
|
||||
|
||||
**C. 被控端形态**
|
||||
|
||||
10. 是不是系统服务？开机自启吗？锁屏/注销/UAC 提权界面能不能连？
|
||||
11. 安装包形态、是否需要管理员权限、卸载残留
|
||||
|
||||
**D. 网络行为（只看宏观，不要深入协议）**
|
||||
|
||||
12. 连接时用户是否能看到"直连 / 中转"标识
|
||||
13. 典型连接耗时、转中继时的画质变化
|
||||
14. 端口/协议宏观特征：UDP 还是 TCP 为主、监听端口是否固定
|
||||
|
||||
**E. 商业化（可选但有用）**
|
||||
|
||||
15. 免费额度/收费点/增值功能边界
|
||||
|
||||
### 2.3 逆向资料回填位置
|
||||
|
||||
| 资料 | 回填到 |
|
||||
|---|---|
|
||||
| A 组 | 本文 §6「产品范围基线」+ 里程碑取舍 |
|
||||
| B/C 组 | §3.3 session（身份模型影响状态机） |
|
||||
| D 组 | §3.2 conn（验证我们的打洞/中继策略） |
|
||||
| E 组 | 不在本文，属于商业决策 |

||||
|

|
||||
|
||||
## 3. 模块级设计规范
|
||||
|
||||
### 3.1 `proto` — 协议
|
||||
|
||||
**职责**：信令消息、控制消息、媒体容器格式。三端（agent/viewer/信令服务）共享契约。
|
||||
|
||||
**设计点**
|
||||
- **双协议分离**：信令协议（`signaling.rs`，文本友好、低频、可 JSON）与媒体控制协议（`lib.rs`，二进制、高频）**不要混**。前者要便于抓包排查，后者要极致紧凑。
|
||||
- **版本协商**：`SIGNALING_VERSION` 不一致直接拒绝，不做兼容。媒体协议用"能力协商"而非版本号（见 §3.3）。
|
||||
- **消息演进**：现用 bincode。二期若换 protobuf，**必须一次性切换**，不要两套并存。
|
||||
- **单帧长度上限**：现有 `ensure!(len < 1<<20)` 这类边界检查要保留，且信令侧对端候选列表必须经 `sanitize_candidates`。
|
||||
|
||||
**看谁 / 抄什么**
|
||||
|
||||
| 项目 | 抄什么 | 不抄 |
|
||||
|---|---|---|
|
||||
| RustDesk `libs/hbb_common` | 消息分类方式（信令/中继/控制分层） | 具体协议编码（AGPL + 抄了不互通） |
|
||||
| Moonlight `moonlight-common-c` | **控制消息与媒体分离**的成熟做法 | 它的私有控制协议 |
|
||||
|
||||
**产出物**：`crates/proto/src/{lib.rs, signaling.rs}`
|
||||
|
||||
---
|
||||
|
||||
### 3.2 `conn` — 连接层（最值得借鉴的一块）
|
||||
|
||||
**职责**：信令客户端、打洞编排、路径选择、QUIC 会话、保活。
|
||||
|
||||
**设计点**
|
||||
- **`PathProvider` 抽象**（已在《打洞与信令设计.md》定义）：现在只实现 Direct，类型上预留 Relay。
|
||||
- **打洞编排**：候选收集（v6/Host/UPnP/Reflexive/Predicted）→ 排序 → 信令交换 → 同步打洞 → 落选清理。
|
||||
- **同一 socket 双角色**：打洞用的 UDP socket 必须与后续 QUIC 是同一个，否则洞不在同一映射上。
|
||||
- **保活**：按双方 `binding_timeout_s` 折半，5–60s。**这是"连一会儿就断"的根治点。**
|
||||
- **不用 QUIC 握手当探测**：先用轻量 UDP 探测包确认通路（秒级失败），再 `connect`。
|
||||
|
||||
**看谁 / 抄什么**
|
||||
|
||||
| 项目 | 抄什么 | 许可 |
|
||||
|---|---|---|
|
||||
| **iroh** | **整套**：打洞编排、中继回退、地址发现。技术栈与你们重合（Rust + quinn） | Apache-2.0 ✅ **可直接依赖** |
|
||||
| webrtc-rs / pion/ice | ICE 状态机、候选配对（candidate pairing）策略 | MIT/Apache ✅ |
|
||||
| Tailscale / headscale | DERP 中继的**回退判定条件**与降级策略 | BSD-3 ✅ |
|
||||
| RustDesk `rendezvous_mediator` 相关 | 信令 ↔ 打洞的**编排顺序**（读思路） | AGPL ⚠️ 只读 |
|
||||
| libjuice / libnice | ICE 精简实现（作为对照，不必依赖） | MPL / LGPL |
|
||||
|
||||
> **建议**：`conn` 优先评估**直接依赖 iroh**。它解决的正是你们纠结的"打洞要不要中继"，而且给了"直连优先、失败回退"的完整实现。自研仅当 iroh 有硬伤（体积、可控性、特定 NAT 场景）时才考虑。
|
||||
|
||||
**产出物**：`crates/conn/`
|
||||
|
||||
---
|
||||
|
||||
### 3.3 `session` — 会话编排（"一体程序"的核心）
|
||||
|
||||
**职责**：会话状态机、角色仲裁、能力协商、生命周期管理、被控端准入控制。
|
||||
|
||||
**设计点**
|
||||
- **状态机双线**：主控线 / 被控线各自独立，同一进程可并发（被控中也能主控别人）。
|
||||
- **角色仲裁**：打洞阶段双方对称，**谁先打通谁定角色**（被控方做 QUIC server），不预设。
|
||||
- **能力协商**：被控端上报硬件能力（可用编码器、最大分辨率、帧率上限、是否支持音频），主控端选择。**用能力协商代替版本号**——旧客户端缺字段就是"不支持"，天然向后兼容。
|
||||
- **准入控制**：单会话/多会话、白名单、单次确认弹窗。**这一条直接来自 §2 逆向需求 B 组第 7/9 项**，等资料回填后定稿。
|
||||
- **失败出口**：`PunchFailReason::user_hint()` 必须一路透传到 UI，不允许出现无解释的"连接中"。

### 3.4 `media` — 编解码抽象
|
||||
|
||||
**职责**：编码/解码 trait、各平台后端、零拷贝通路、码率自适应闭环。
|
||||
|
||||
**设计点**
|
||||
- **不对称策略**：**编码用 FFmpeg**（只在 Win/Linux，桌面端不心疼包体），**解码用平台原生**（四个主控平台都要，移动端必须硬解且要零拷贝）。
|
||||
- **trait 收口**（见《多平台架构设计.md》§4 决策 4），上层不允许出现平台判断。
|
||||
- **零拷贝**：解码器直接输出到渲染表面（D3D11 纹理 / `SurfaceView` / `CAMetalLayer`），中间不做 CPU 拷贝。
|
||||
- **软硬兜底**：硬编失败回落 openh264；硬解失败回落软解（桌面可，移动端应直接提示而非硬撑）。
|
||||
- **码率自适应闭环**：接收端统计（丢包/抖动/帧间隔 p95）→ 反馈编码端 → AIMD 调码率。协议已留 `RateReport`（见 B侧设计文档 B2）。
|
||||

|

|
||||
### 3.5 `platform` — L0 平台层（抄不到，只能自己写）
|
||||
|
||||
**职责**：抓屏、注入、渲染表面、音频 IO、权限、常驻。
|
||||
|
||||
**为什么抄不到**：这层是各平台 API 的体力活。参考项目能给的是"用哪个 API、踩过什么坑"，不是可复用代码。
|
||||
|
||||
**设计点**
|
||||
|
||||
| 平台 | 关键坑 |
|
||||
|---|---|
|
||||
| Win 抓屏 | DXGI DD 在**会话切换/RDP 断开**时失效，必须处理 `DXGI_ERROR_ACCESS_LOST` 并重建 |
|
||||
| Win 注入 | 服务进程注入到用户会话需要 `CreateProcessAsUser` + 会话隔离处理；UAC 提权界面默认收不到输入（需 `uiAccess` 签名） |
|
||||
| Win 常驻 | 服务 + 用户会话代理双进程，锁屏可连靠的是**服务侧保持会话** |
|
||||
| Linux 抓屏 | X11 用 XShm/XComposite；**Wayland 必须走 PipeWire + xdg-desktop-portal**（有授权弹窗，无法静默） |
|
||||
| Linux 注入 | X11 用 XTest；**Wayland 用 libei/uinput**（uinput 需 root 或 udev 规则） |
|
||||
| Linux 常驻 | systemd 服务 + 会话切换处理（Wayland 的 portal 授权是最大障碍） |
|
||||
| 渲染表面 | 四平台各一套；**必须支持"表面尺寸≠视频尺寸"的缩放与拉伸模式** |
|
||||
|
||||
**看谁**
|
||||
|
||||
| 项目 | 看什么 |
|
||||
|---|---|
|
||||
| Sunshine `src/platform/{windows,linux}` | 抓屏与注入的分平台组织方式、Wayland 处理 |
|
||||
| RustDesk `libs/scrap` | 同样的抓屏抽象（多平台统一 trait）——**这是它最有价值的部分** |

|
||||
|
||||
### 3.6 `agent-core` / `viewer-core` — 两条链路
|
||||
|
||||
**职责**：把现有 `agent`/`viewer` 的 main 逻辑抽成库，供一体程序按角色调用。
|
||||
|
||||
**设计点**
|
||||
- **`agent-core`**：capture → encode → 打包 → 发送；输入接收 → 注入。A 已在进行中（`agent-core/src/lib.rs` 398 行）。
|
||||
- **`viewer-core`**：接收 → 解码 → 渲染表面；输入采集 → 发送。
|
||||
- **生命周期**：两者都不允许自己决定退出，由 `session` 层驱动。
|
||||
- **单槽 latest-wins**：现有做法保留（网络慢时只发最新帧），这是正确设计。
|
||||
|
||||
**看谁**：RustDesk（抽库方式）、Sunshine/Moonlight（管线组织）。
|
||||
|
||||

|
||||
|
||||
### 3.7 `apps/*` — UI 与常驻（第二个抄不到的地方）
|
||||
|
||||
**职责**：UI 壳、常驻服务、安装包。
|
||||
|
||||
**设计点**
|
||||
- **硬约束**：所有业务逻辑在 Rust，UI 只调一层稳定 API（决定了将来能否换 UI 框架）。
|
||||
- **视频走原生子表面**，绝不在 WebView 里逐帧渲染。
|
||||
- **一体 = 一个安装包 + 两个进程**：前台 UI + 后台被控服务，本地 IPC。
|
||||
- **移动端只有前台进程**（纯主控）。

||||

## 5. 许可结论与依赖策略
|
||||
|
||||
| 许可 | 能否进产品 | 项目 |
|
||||
|---|---|---|
|
||||
| MIT / Apache-2.0 / BSD | ✅ 可依赖、可移植 | iroh、webrtc-rs、pion、coturn、libwebrtc、UniFFI(MPL 弱) |
|

| LGPL | ⚠️ 可动态链接，改库要开源 | FFmpeg、GStreamer、libnice |
|
||||
| **GPL / AGPL** | ❌ **不可进代码** | **RustDesk(AGPL)、Sunshine/Moonlight(GPL)** |
|
||||
|
||||
**AGPL 特别提示**：网络服务也算分发。引入 RustDesk 代码 = 你们整个产品连服务端都要开源。
|
||||
|
||||
**依赖准入流程**（补充进《Git协作规范.md》的合并规则）：新增依赖必须在 PR 描述里写明**许可证 + 是否修改其源码**，由另一人确认。

## 0. 一句话架构
|

|
||||
**一个 Rust 核心 + 一层薄平台适配 + 可替换的 UI 壳。**
|
||||
业务逻辑（连接/打洞/会话/协议）100% 在 Rust 里跨平台共享；只有**抓屏、编解码、注入、渲染表面**四件事分平台写；UI 层只管"壳"，**永远不碰视频流**。
|
||||
|
||||

|
||||
|
||||
## 1. 纵向分层
|
||||
|
||||
```
|
||||
┌──────────────────────────────────────────────────────────┐
|
||||
│ L4 UI 壳 Win/Linux/Android/iOS 各自实现 │
|

├──────────────────────────────────────────────────────────┤
|

│ L0 平台层 platform 唯一必须分平台的地方 │
|

│ 抓屏 / 注入 / 音频IO / 渲染表面 / 权限 / 常驻 │
|
||||
└──────────────────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
**分界线原则**：L1 以上任何代码不允许出现 `#[cfg(windows)]`。平台差异只能通过 L0 的 trait 暴露。
|
||||

```
|
||||
|
||||
`agent-core` 与 `viewer-core` 的拆分是**一体化的前提**：现在的 `agent`/`viewer` 是两个 main，必须先变成库，才能被同一个进程按角色调用。A 正在做的 `agent-core` 抽取就是在铺这条路。

|
||||
## 4. 六个关键决策
|
||||
|
||||
### 决策 1：视频渲染绝不走 UI 框架
|
||||
|
||||
从 WebView / Compose / Flutter 里逐帧渲染 60fps 视频必然掉帧、增延迟。
|
||||
**做法**：UI 框架只画"壳"，视频走**原生子表面**叠加在 UI 之上——
|
||||
Win: 子 HWND + D3D11；Linux: 子窗口 + GL；Android: `SurfaceView`；iOS: `UIView` + `CAMetalLayer`。
|
||||
MediaCodec / VideoToolbox 都能**直接解码到该 Surface，零拷贝**。这是 Parsec/ToDesk 这类产品的通行做法。
|
||||
|
||||
### 决策 2：UI 框架 —— 推荐 Tauri v2，但必须可替换
|
||||
|
||||
| 方案 | 覆盖 | 评价 |
|
||||
|---|---|---|
|
||||
| **Tauri v2** | Win/Linux/Android/iOS | ✅ 推荐：Rust 原生、一套 UI 四端、IPC 天然 |
|
||||
| Flutter | 四端 | UI 强，但 Rust 桥（flutter_rust_bridge）+ 平台视图叠加更绕 |
|
||||
| 各平台原生 ×4 | 四端 | 性能最好，**2-3 人团队不可能维护** |
|
||||
|
||||
选 Tauri v2 的理由：你们本来就写 Rust，视频走原生表面后 WebView 只做表单和列表，性能足够。
|
||||
**代价**：Tauri 移动端还不够成熟（WKWebView 与原生 surface 叠加、生命周期）。所以——
|
||||
|
||||
> **硬性约束：所有业务逻辑必须在 Rust 里，UI 只通过一层稳定 API 调用。**
|
||||
> 这样移动端若体验不达标，可以单点退化成原生 Kotlin/Swift + UniFFI，桌面仍用 Tauri，核心零改动。
|
||||
|
||||
### 决策 3：Rust ↔ 移动端绑定用 UniFFI
|
||||
|
||||
6 个平台角色组合下手写 JNI/FFI 会失控。UniFFI 从 Rust 生成 Kotlin/Swift 绑定，含 async、错误类型、对象生命周期，是当前标准解法。
|
||||
|
||||
### 决策 4：编码用 FFmpeg，解码用平台原生
|
||||
|
||||
不对称，但都有理由：
|
||||
|
||||
- **编码（只在 Win/Linux 被控端）**：用 FFmpeg 统一接管 NVENC/QSV/AMF/VAAPI，openh264 软编兜底。桌面端不心疼包体，省下大量适配。
|
||||
- **解码（四个主控平台都要）**：直接用平台原生 API。
|
||||
- 移动端**必须**硬解（软解烧电池、发热、跑不动 1080p60）
|
||||
- 平台原生能零拷贝直出渲染表面，FFmpeg 反而多一次拷贝
|
||||
- 绕开 FFmpeg 在 Android/iOS 上的交叉编译地狱和许可问题
|
||||
|
||||
`media` crate 用 trait 收口：
|
||||
|
||||
```rust
|
||||
pub trait VideoDecoder {
|
||||
fn configure(&mut self, cfg: &VideoConfig, target: SurfaceHandle) -> Result<()>;
|
||||
fn decode(&mut self, packet: &[u8]) -> Result<Option<FrameHandle>>;
|
||||
}
|
||||
|
||||
pub trait VideoEncoder {
|
||||
fn configure(&mut self, cfg: &EncodeConfig) -> Result<()>;
|
||||
fn encode(&mut self, frame: &FrameHandle, out: &mut Vec<u8>) -> Result<()>;
|
||||
fn request_keyframe(&mut self);
|
||||
}
|
||||
```
|
||||
|
||||
### 决策 5："一体程序" = 一个安装包 + 两个进程
|
||||
|
||||
用户视角是一个 app，实现上职责分离：
|
||||
|
||||
```
|
||||
┌────────────────────────┐ ┌──────────────────────────┐
|
||||
│ 前台进程（UI） │ IPC │ 后台常驻（被控服务） │
|
||||
│ 主控画面 / 设备列表 │<──────>│ 抓屏·编码·注入·保活 │
|
||||
│ 退出即结束 │ 本地管道│ 开机自启 / 锁屏可连 │
|
||||
└────────────────────────┘ └──────────────────────────┘
|
||||
▲ ▲
|
||||
│ 移动端只有这一个 │ 仅 Win/Linux
|
||||
```
|
||||
|
||||
理由：**两种角色的生命周期天然冲突**——被控要"开机就在、没人操作也在"，主控要"跟窗口走、关了就走"。硬塞进一个进程会导致主控一退出就掉线。
|
||||
IPC 用命名管道（Win）/ Unix socket（Linux），或复用 QUIC 走本地回环。
|
||||
|
||||
### 决策 6：中继接口必须预留 —— 哪怕现在不实现
|
||||
|
||||
`conn` 层定义：
|
||||
|
||||
```rust
|
||||
pub trait PathProvider {
|
||||
/// 返回一条可用数据通道：直连优先，失败时可回退
|
||||
async fn establish(&self, peer: &PeerInfo) -> Result<Path>;
|
||||
}
|
||||
|
||||
pub enum Path { Direct { addr: SocketAddr }, Relay { endpoint: EndpointId } }
|
||||
```
|
||||
|
||||
现在只实现 `Direct`。**但类型上留出 `Relay`**，将来补中继不必动会话层。
|
||||
|
||||
> ⚠️ **这条与"不做中继"的决定直接相关，见 §6。**
|
||||
|
||||
---
|
||||
|
||||
## 5. 会话状态机（L3 核心）
|
||||
|
||||
一体程序两条线：
|
||||
|
||||
```
|
||||
主控线: Idle → Signalling → Punching → Handshaking → Streaming → Closing
|
||||
被控线: Idle → Registered → Incoming → Punching → Handshaking → Serving → Closing
|
||||
↑ 同一进程两线可并发（被控中也能主控别人）
|
||||
```
|
||||
|
||||
要点：
|
||||
- 打洞阶段**双方对称**：谁都不预设客户端/服务端，各自向对端候选发包，谁先打通谁定角色（被控方做 QUIC server）
|
||||
- 会话能力协商：分辨率、编码器、码率上限、是否带音频——由**被控端**根据硬件能力给候选，主控端选
|
||||
- 单进程内用 tokio 一runtime 跑多会话；被控同时只服务一个主控（可配置）
|
||||
|
||||
---
|
||||
|
||||
## 6. ✅ 已裁决：不做中继（2026-10-28）
|
||||
|
||||
> **裁决结论**：公司不提供中继服务器，中继不做。以下保留原始分析以免后人重蹈讨论。
|
||||
|
||||
**手机在蜂窝网络下几乎 100% 处于运营商级 NAT（CGNAT），打洞打不通。**
|
||||
这不是实现问题，是网络事实——`100.64.0.0/10` 那段地址根本没给你可映射的公网端口。
|
||||
|
||||
后果：**"主控端支持安卓/iOS" + "不做中继" = 手机只能在 WiFi 下用。**
|
||||
地铁上、外面、用流量，一律连不上。
|
||||
|
||||
三条出路：
|
||||
|
||||
| 方案 | 代价 | 说明 |
|
||||
|---|---|---|
|
||||
| **A. 只靠 IPv6** | 部分用户不可用 | 国内三大运营商 v6 覆盖率高，手机 v6 可用性远好于 v4 公网 |
|
||||
| B. 补一个只为移动端服务的中继 | 视频带宽成本 | **已排除：公司不提供额外服务器** |
|
||||
| C. 接受"手机只能 WiFi" | 产品力受限 | 零成本，但要写进产品说明 |
|
||||

### 6.1 裁决内容与边界（2026-10-28）
|
||||
|
||||
| 项 | 裁决 |
|
||||
|---|---|
|
||||
| 中继 / TURN / relay 服务器 | **不做**。公司不提供额外服务器，且无预算计划 |
|
||||
| IPv6 | **一等公民**。候选地址排序 v6 优先，`signaling.rs` 已实现 |
|
||||
| 中继接口预留 | **不预留**。不写 `PathProvider` trait、不写 `Path::Relay` 变体 |
|
||||
| 连接层边界 | **仍要做**。理由见 §6.2，与中继无关 |
|
||||
|
||||
**为什么不留中继接口**：留接口的收益是「将来补中继不用动会话层」，但既然中继已被排除，
|
||||
`Path::Relay` 这类变体永远不会被构造，只会产生 `dead_code` 警告，要么 `#[allow]` 要么日后删除。
|
||||
**零收益的预留就是纯负担。**
|
||||
|
||||
### 6.2 连接层边界与中继接口是两件事
|
||||
|
||||
这两件事常被混为一谈，必须分开：
|
||||
|
||||
| | 内容 | 现在做不做 |
|
||||
|---|---|---|
|
||||
| **连接层边界** | 把"怎么连"（信令/打洞/直连）与"连上干什么"（收流/解码/渲染）分开 | ✅ **要做** |
|
||||
| **中继接口** | `enum Path { Direct, Relay }` 这类类型预留 | ❌ **不做** |
|
||||
|
||||
连接层边界本身就有独立价值，与中继无关：
|
||||
|
||||
1. **连接方式确定会变**：局域网 `IP:端口` → 将来设备码 + 打洞，这是已定的路线；
|
||||
2. **安卓主控要复用**：`viewer-core` 收流解码渲染不应知道对面是怎么连上的；
|
||||
3. **可测性**：解码逻辑能脱离真连接单独测试。
|
||||
|
||||
做法是把它抽成一个函数边界（输入目标描述、返回 `quinn::Connection`），
|
||||
**不是**定义 trait 或枚举。
|
||||
|
||||
### 6.3 对产品的影响（必须写进对外说明）
|
||||
|
||||
| 网络环境 | 能否连接 |
|
||||
|---|---|
|
||||
| 双方任一侧无公网 IPv6，且处于 CGNAT 后 | ❌ **无法连接，无解** |
|
||||
| 双方都有公网 IPv6 | ✅ 可直连 |
|
||||
| 局域网 / 双方都有可打洞的公网 IPv4 | ✅ 可直连 |
|
||||
| 对称 NAT（双方） | ❌ 通常不通 |
|
||||
|
||||
**这不是 bug，是已知边界。** 用户在外网连不上时，UI 必须给出可执行提示
|
||||
（`PunchFailReason::user_hint()` 已提供文案），不能停留在"连接中"。
|
||||
|
||||

|
||||
|
||||
## 7. 分期路线（不要一次做 6 个组合）
|
||||
|
||||
| 里程碑 | 内容 | 预估 | 依赖 |
|
||||
|---|---|---|---|
|
||||
| **M1** | Win↔Win 打通：信令 + 打洞 + 证书钉扎 | 2-3 周 | 协议已就绪 |
|
||||
| **M2** | Win 一体化：agent-core 抽库、会话状态机、前台/后台双进程 | 2-3 周 | M1 |
|
||||
| **M3** | Win 被控服务化（开机即在线、锁屏可连、UAC 处理） | 2 周 | M2 |
|
||||
| **M4** | Linux 被控（X11 先行，Wayland/PipeWire 预留） | 2-3 周 | M2，A 在做 |
|
||||
| **M5** | 桌面 UI（Tauri v2 壳 + 原生视频表面） | 3 周 | M2 |
|
||||
| **M6** | **Android 主控**（MediaCodec + UniFFI + 触摸映射） | 3-4 周 | M5 |
|
||||
| **M7** | **iOS 主控**（VideoToolbox + SwiftUI/UniFFI） | 3-4 周 | M6 |
|
||||
| **M8** | Linux 主控（复用 M5 的桌面 UI） | 1 周 | M5 |
|
||||
| 穿插 | 音频(Opus) / 文件传输 / 多屏 | 各 1-2 周 | — |
|
||||
|
||||
**先做 Android 再做 iOS**：不用苹果开发者账号、真机调试方便、热重载快、审核风险低。iOS 放最后。
|
||||
|
||||
---
|
||||
|
||||
## 8. ⚠️ 必须说清楚的人力问题
|
||||
|
||||
现有团队 **2-3 人**，目前连"Win↔Win 打通"都还没做完。而这份需求是：
|
||||
|
||||
- 2 个被控平台（抓屏 + 编码 + 注入 + 服务化）× 各自两套显示服务器（Linux X11/Wayland）
|
||||
- 4 个主控平台（解码 + 渲染 + 输入 + UI）× 各自一套原生集成
|
||||
- 外加信令、打洞、音频、文件、多屏、账号体系
|
||||
|
||||
**这是 6-10 人年的工作量，2-3 人做不完。** 不是唱衰，是排期事实——Android + iOS 两个平台的 UI 和平台集成，单独拿出来就够一个人全职做半年。
|
||||
|
||||
可行的收缩方式（选一个）：
|
||||
|
||||
1. **砍掉 iOS**（苹果审核 + 真机调试 + 开发者账号成本最高，收益最小）
|
||||
2. **移动端只做 Android**，iOS 用 Web 端替代（但 Web 端无法硬解，体验差）
|
||||
3. **桌面优先，做深做透**，移动端放到"产品验证之后"，先招人
|
||||
4. 移动端主控**外包**，核心协议和桌面端自己掌握
|
||||
|
||||
我的建议是 **3 或 1**：先把 Win/Linux 两端做成一款真的好用的产品（含打洞、服务化、音频、文件），移动端等有用户了再投入。现在同时铺 6 个平台，最大概率是每个都半成品。
|
||||
|
||||

|
||||
|
||||
## 9. 给 A / B 的分工调整建议
|
||||
|
||||
| 人 | 主责 | 说明 |
|
||||
|---|---|---|
|
||||
| A | `platform/` 被控侧：Win 抓屏/编码/注入/服务化 + Linux 被控 | 与现状一致 |
|
||||
| B | `proto/` + `conn/` + `session/` + `viewer-core/` + 桌面 UI | 与现状一致 |
|
||||
| — | **移动端（Android/iOS）** | **无人** ← 这是缺口 |
|
||||
|
||||
现有分工在"桌面 + 协议"上是自洽的，**移动端是纯增量，必须补人或砍需求**。

## 10. 开放问题（需要拍板）
|
||||
|
||||
> §10 第 1 条已于 2026-10-28 裁决，见 §6。
|
||||
|
||||
1. ~~中继：确认走 §6 的 A 方案（v6 优先、留接口不实现）？~~
|
||||
**已裁决：不做中继、不留接口、v6 优先、但保留连接层边界。详见 §6.1 / §6.2。**
|
||||
2. 移动端：先 Android 还是直接砍 iOS？
|
||||
3. UI 框架：确认 Tauri v2，还是先原生桌面 + 后面再说移动？
|
||||
4. 账号体系：现在是"输验证码"，要支持设备列表就得有账号/设备 ID 体系——什么时候做？
|
||||
5. 被控服务化后，主控端要不要支持"无人值守开机连接"（有安全含义，需要固定密码 + 白名单）？

# 打洞与信令设计（无中继方案）
|
||||
|
||||
> 状态：协议契约已落在 `common/src/signaling.rs`，已合入 main（`703eb64`）。
|
||||
> 决策：**不做中继（无 TURN / coturn）**，服务器只保留信令 + STUN 职能。
|
||||
> **裁决确认（2026-10-28）**：公司不提供中继服务器，本决策为最终结论，
|
||||
> 同时**不预留中继接口**（理由见《多平台架构设计.md》§6.1 / §6.2）。
|
||||
> 关联：`构建运行手册.md` §7 第 4 项、`Git协作规范.md` 二·B 第 ③ 项。
|
||||
|
||||
## 1. 结论先行：信令不是中继
|
||||
|
||||
| | 信令服务器 | 中继服务器（已砍掉） |
|
||||
|---|---|---|
|
||||
| 承载媒体流量 | ❌ 不承载 | ✅ 全部承载 |
|
||||
| 生命周期 | 只在建连那几秒 | 整个会话期间 |
|
||||
| 成本 | 一台最低配 VPS 足够 | 视频流带宽，主要成本项 |
|
||||
| 必要性 | **必须**（无它则无法交换地址） | 可选（可用率兜底） |
|
||||
|
||||
砍掉中继 ≠ 不要服务器。信令必须保留，因为它解决的是死循环：双方都在 NAT 后，
|
||||
各自只知道自己内网地址，**"自己的公网映射"这个信息只有第三方发包过来时才能看见**。
|
||||
|
||||
## 2. 无中继的代价：可用率，不是功能
|
||||
|
||||
打洞成功率由 NAT 类型决定，与代码质量基本无关：
|
||||
|
||||
| NAT 类型 | 典型场景 | 无中继 |
|
||||
|---|---|---|
|
||||
| Full cone / Restricted cone | 家用路由器默认 | ✅ 很高 |
|
||||
| Port-restricted cone | 家用宽带常见 | ✅ 需同时发包 |
|
||||
| Symmetric NAT | 部分企业网关 | ⚠️ 仅端口可预测时可行 |
|
||||
| CGNAT（`100.64.0.0/10`） | 移动/社区宽带 | ❌ 无解（IPv6 除外） |
|
||||
|
||||
预期 P2P 成功率 **80–90%**，其余连不上。
|
||||
|
||||
**产品边界（需写进对外说明）**：目标用户框定为「家用宽带 + IPv6 可用 + 可开 UPnP」；
|
||||
企业网络 / CGNAT 标注为不支持。这样剩余失败就不是 bug，是已知边界。
|
||||
|
||||
## 3. 打洞流程（协议见 `common/src/signaling.rs`）
|
||||
|
||||
```
|
||||
agent 信令服务器 viewer
|
||||
|-- Register(info) ------->|<------- Register(info) -----|
|
||||
|<-- Registered(observed) -|------ Registered(observed) ->| observed = 公网映射（等价一次 STUN binding）
|
||||
|<-- PeerReady(peer info) -|------ PeerReady(peer info) -->| + 打洞前景 outlook
|
||||
|<-- PunchPlan(start_in) --|------ PunchPlan(start_in) --->| 两侧 start_in 不同，绝对时刻对齐
|
||||
| （双方同时向对端候选列表发包，多轮） |
|
||||
|<========= 打通：UDP 直连 → QUIC 握手 + 证书钉扎 =========>|
|
||||
|--- PunchReport(Connected) ->|<---- PunchReport ----------|
|
||||
```
|
||||
|
||||
### 3.1 候选地址与优先级
|
||||
|
||||
`Candidate::score()`：IPv6（+100）> UPnP 显式映射(90) > 本机地址(80) > 公网反射(60) > 端口预测(40)。
|
||||
|
||||
**IPv6 是无中继策略的最强后盾** —— 双方都有公网 v6 就是真直连，成功率≈100%，
|
||||
因此候选列表按 v6 → v4 排序，`EndpointInfo` 两类都带。
|
||||
|
||||
### 3.2 同时发包的时间对齐（不需要时钟同步）
|
||||
|
||||
两侧 RTT 不同，若下发同一个延迟，RTT 大的一方晚发包就打不上。服务器按
|
||||
`punch_start_delay_ms(own_rtt, max_rtt, margin)` 给两侧算不同的 `start_in_ms`：
|
||||
|
||||
```
|
||||
start_in_ms = max_rtt_ms / 2 + margin_ms - own_rtt_ms / 2
|
||||
```
|
||||
|
||||
`start_in_ms` 是**相对消息送达**的延迟，所以两端时钟不需要同步，误差≈单程抖动。
|
||||
|
||||
### 3.3 保活
|
||||
|
||||
NAT 的 UDP 映射默认 30s 左右超时，洞是出站包维持的，超时后静默关闭
|
||||
（表现为"连上了一会儿就断"）。`keepalive_secs()` 取双方 `binding_timeout_s`
|
||||
较小值折半，夹在 5–60s。
|
||||
|
||||
## 4. 提高成功率的实现清单（按性价比）
|
||||
|
||||
1. **IPv6 优先**：候选排序已实现；agent 侧需枚举全局 v6 地址填 `CandidateKind::Host`。
|
||||
2. **UPnP / NAT-PMP / PCP**：agent 启动时就尝试为 `PUNCH_UDP_PORT(47800)` 申请映射，
|
||||
成功后以 `CandidateKind::Upnp` 补报（走 `ClientMsg::UpdateCandidates`）。
|
||||
一次成功就把对称 NAT 变成可直连，收益最大。
|
||||
3. **双方同时发包**：见 §3.2，这是打洞能成的关键。
|
||||
4. **端口预测**：`PortAllocation::Sequential/Preserved` 时才值得做，`Predicted` 候选由
|
||||
`sanitize_candidates` 统一清洗（去重、丢端口 0、上限 32 个）。
|
||||
5. **多轮重试**：`rounds=3 / 200ms`，一次不通不代表不通。
|
||||
|
||||
**不要走 TCP 打洞**：QUIC 只跑 UDP，TCP simultaneous open 成功率低，性价比不值得。
|
||||
|
||||
## 5. 实现约束（两端各自注意）
|
||||
|
||||
- **别拿 QUIC 握手当探测**：`quinn::Endpoint::connect` 打不通会持续重试，失败判定被
|
||||
idle timeout 拖很久。应先用同一 UDP socket 发轻量探测包确认通路（秒级），
|
||||
确认后再 `connect`；端口扫描也放这一层，便宜且可并行。
|
||||
- **UDP socket 复用**：打洞用的 socket 要和后续 QUIC 用同一个，否则洞不在同一个映射上。
|
||||
`quinn::Endpoint` 支持同时 `accept()` 与 `connect()`，可以在一个 Endpoint 上做完整流程。
|
||||
- **固定端口**：`47800` 对端口预测和用户手动端口转发都友好，不要随机端口。
|
||||
|
||||
## 6. 安全（本次必须同步改，否则公网不可用）
|
||||
|
||||
1. **证书钉扎**：`viewer/src/main.rs` 的 `SkipVerify` 必须替换为对
|
||||
`EndpointInfo.cert_fingerprint` 的校验（`CertFingerprint` 已定义 hex 编解码）。
|
||||
2. **认证**：`ClientMsg::Register.auth` 必须是一次性验证码（替代固定 `123456`/`888888`），
|
||||
带过期与失败限速，否则公网等于没有认证。
|
||||
3. **候选列表视为不可信输入**：一律经 `sanitize_candidates` 后再发包。
|
||||
|
||||
## 7. 失败必须有明确出口（无中继的用户体验下限）
|
||||
|
||||
没有中继兜底，就必须把"为什么连不上"讲清楚，不允许用户停在"连接中"。
|
||||
`PunchFailReason::user_hint()` 已给出每种原因对应的可执行建议，例如：
|
||||
|
||||
- `Cgnat` → "当前处于运营商级 NAT（大内网），无法直连。请改用 IPv6 网络……"
|
||||
- `SymmetricNat` → "请在被控端路由器开启 UPnP 后重试。"
|
||||
- `UdpBlocked` → "当前网络的防火墙拦截了 UDP 出站，请切换手机热点后重试。"
|
||||
|
||||
`punch_outlook()` 还能在**开打之前**就给出前景（`Likely/Possible/Unlikely/Hopeless`），
|
||||
`Hopeless`（CGNAT）时可直接跳过打洞轮次并立刻提示，不让用户白等。
|
||||
|
||||
## 8. 后续动作
|
||||
|
||||

|
||||
|---|---|---|
|
||||
| 1 | `common/src/signaling.rs` 过审合入 main | B 提 PR / A review |
|
||||
| 2 | 信令服务最小实现（WSS/443，配对 + 回推 observed + 下发 PunchPlan） | B |
|
||||
| 3 | agent：候选收集（v6/Host/UPnP/Reflexive）、同步打洞、保活 | A |
|
||||
| 4 | viewer：候选收集、同步打洞、改为证书钉扎 | B |
|
||||
| 5 | 双机联调：家庭宽带 / 手机热点 / CGNAT 三种网络各跑一轮 | A + B |

|
||||
|
||||
---
|
||||
|
||||
## 3. 关键结论：NAT 类型 = 锥形 + 端口保留
|
||||
|
||||
用**同一个本地端口 47800** 分别打两个完全不同的目标，观察公网映射：
|
||||
|
||||
| 目标 | 观察到的公网映射 |
|
||||
|---|---|
|
||||
| Google STUN（境外） | `116.3.201.115:47800` |
|
||||
| 自建信令服务器 `47.98.245.66:47999` | `116.3.201.115:47800` |
|
||||
|
||||
**不同目标 → 同一个公网端口 → 端点无关映射（Endpoint-Independent Mapping，即锥形 NAT），且端口原样保留。**
|
||||
|
||||
按打洞成功率排序：
|
||||
|
||||
```
|
||||
锥形 + 端口保留 ← 本机（最优）
|
||||
锥形 + 端口改写 成功率高
|
||||
对称 NAT 困难，需端口预测
|
||||
CGNAT 基本无解
|
||||
```
|
||||
|
||||
**推论**：信令服务器观察到的地址，对该客户端是**可复用的真实映射**，对端直接向它发包即可打洞，无需端口预测。这是最理想的情形。
|
||||
|
||||
复现命令：
|
||||
|
||||
```powershell
|
||||
# 一定要带 --stun-port，用与打洞相同的端口，否则映射不可比
|
||||
py tools\punch_probe.py --stun --stun-port 47800
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 4. 踩到的坑（Rust 实现必须处理）
|
||||
|
||||
### 4.1 hairpinning：同一公网 IP 下两实例互打会失败
|
||||
|
||||
两个客户端都在 `116.3.201.115` 后面，互相打对方的公网地址，需要路由器支持 **NAT 环回（hairpinning）**。本线路不支持。
|
||||
|
||||
**这不代表真实打洞会失败**——真实场景是两台机器位于**不同**公网 IP 之后。此测试只能验证"信令配对"链路，不能验证穿透能力。
|
||||
|
||||
### 4.2 Windows：ICMP 端口不可达会打断接收循环
|
||||
|
||||
对方尚未启动时发包 → 收到 ICMP port unreachable → 下一次 `recv` 抛 `WSAECONNRESET(10054)`。若把它当致命错误 `break`，接收循环就此死掉，之后对方真打进来也收不到。
|
||||
|
||||
处理方式（两层）：
|
||||
|
||||
```python
|
||||
sock.ioctl(socket.SIO_UDP_CONNRESET, False) # 1) 关闭该行为
|
||||
# 2) 收到该错误时 continue，绝不能 break
|
||||
```
|
||||
|
||||
**Rust 对应**：`tokio` 的 `recv_from` 会返回 `ConnectionReset`，同样不能 `?` 或 `break`。
|
||||
|
||||
### 4.3 发完就退出会漏掉晚到的回包
|
||||
|
||||
对方可能比自己晚启动。发完最后一包立即关闭 socket，会把"晚到的成功"误判为失败。
|
||||
→ 发完后保留 grace 期（默认 2.5s）继续监听。
|
||||
|
||||
### 4.4 部署层的两道防火墙
|
||||
|
||||
| 层 | 现象 | 处理 |
|
||||
|---|---|---|
|
||||
| 主机 ufw | `INPUT DROP`，无规则则静默丢弃 | `ufw allow 47999/udp` |
|
||||
| 云安全组 | 包到不了网卡（tcpdump 零捕获） | 控制台加 UDP 入方向规则 |
|
||||
|
||||
**排查手法**：`tcpdump -n -i any udp port <port>` 零捕获 = 包在到达主机前就被丢，问题在云安全组而不在主机防火墙。
|
||||
|
||||
> 注意：首次配置时误把安全组规则设成了 **TCP**，UDP 包仍被丢弃。协议类型必须选 UDP。
|
||||
|
||||
### 4.5 假阳性：信令回复被误判为"打通"
|
||||
|
||||
客户端在拿到对端地址前会反复注册，服务器的 `PEER` / `WAIT` 回复可能在 `discover_peer` 返回之后才到达。若接收线程不做区分，会把**服务器发来的回复**当成"对方打进来了"，输出假的"✅ 打洞成功"。
|
||||
|
||||
实测踩到的形态：报告的"对方源地址"是**信令服务器的 IP:端口**（`47.98.245.66:47999`），包长 22 字节——而真正的打洞包固定是 **16 字节**（`PUNCHv1|` + 8 字节时间戳）。
|
||||
|
||||
**判据（Rust 实现必须照做）**：
|
||||
|
||||
1. 只认以协议魔数开头的包，长度必须是约定值
|
||||
2. 显式排除信令服务器的 `IP:端口`
|
||||
3. 结论里如果出现"非打洞包 N 个"，说明收到了信令回复，**不能**据此判定成功
|
||||
|
||||

|
||||
|
||||
## 5. 尚未验证
|
||||
|
||||
| 项 | 为什么重要 | 怎么验 |
|
||||
|---|---|---|
|

## 6. 对实现的影响
|
||||
|
||||
1. **信令服务器的职责就此确认**：注册、配对、回推观察到的源地址。不承载媒体，建连后即退出。
|
||||
2. **信令与打洞必须复用同一个 socket**：服务器看到的映射端口，必须就是打洞时使用的端口，否则映射不可复用。
|
||||
- Rust 实现中：该 socket 需继续交给 `quinn::Endpoint` 使用（一次绑定，三处复用：信令 / 打洞 / QUIC）。
|
||||
3. **失败判定要快**：先做 NAT 行为探测，若判定为对称 NAT 直接给出结论，不必耗完多轮。
|
||||
4. **保活**：NAT 表项会超时，建连后需按 `binding_timeout_s` 折半做 keepalive（协议中已定义 `keepalive_secs()`）。

### 6.1 待修问题（已定位，尚未修，均在 Windows `agent/`）
|
||||
|
||||
1. **错误验证码时 `AuthFail` 送不达**：`agent/src/main.rs` 写完 `AuthFail` 后立刻
|
||||
`send.finish()` 并返回，进程退出会把 QUIC 缓冲区里尚未发出的数据一起带走，
|
||||
客户端只会看到 `connection lost` 而不是 `AuthFail`。
|
||||
修法：`finish()` 后等对端读到并挂断（`conn.closed()` + 超时）再退出。
|
||||
|
||||
2. **软编路径下静止桌面仍不响应关键帧请求**（`04c02d9` 只修了 NVENC 那一半）：
|
||||
`agent/src/capture.rs` 的 `Ok(false)`（画面未变）分支里，`force_key` 被
|
||||
`keyreq.swap` 消费后，只有 `EncoderKind::Nvenc` 分支拿它去重编 IDR；
|
||||
`EncoderKind::Soft` 分支仍然只是「重发最后一帧码流副本」，标志被直接丢弃。
|
||||
后果：**无 N 卡 / 驱动异常（走软编兜底）的机器上，解码端一旦出错，静止画面下
|
||||
永远拿不到 IDR，表现为黑屏。**
|
||||
修法：软编路径同样保留最近一帧裸像素，`force_key` 时重编一个真关键帧。
|
||||
|
||||
3. **单次 `KeyFrameReq` 可能被静默吞掉**：同一个 `keyreq.swap(false, …)` 写在了
|
||||
`if last_sent.elapsed() > 500ms` 的**外面**，因此请求若落在距上次发送 500ms 之内，
|
||||
标志已被消费但分支不进入，该次请求就丢了，必须等下一次请求才可能生效
|
||||
（主控端目前周期性重发，故表现为延迟而非永久黑屏）。
|
||||
修法：把 `swap` 移进时间闸内，或先在闸外预判、进闸后再消费。

### 8.1 现状与边界（重要）
|
||||
### 8.1 架构：会话层抽到 agent-core
|
||||
|
||||
本期**只在新增文件里做，未改动 Windows `agent/`**，原因见下：
|
||||
平台差异只留在采集/注入两个模块里，QUIC 握手、认证、编码、丢帧、输入分发全部共用，
|
||||
**主控端 viewer 不需要任何改动**：
|
||||
|
||||
| crate / 文件 | 职责 | 当前使用者 |
|
||||
| crate / 文件 | 职责 | 平台 |
|
||||
|---|---|---|
|
||||
| `agent-core/src/lib.rs` | QUIC/TLS 握手、传输调优、验证码认证、会话/select 循环、latest-wins 单槽、输入分发，以及软件编码视频管线（openh264） | **仅 linux-agent** |
|
||||
| `agent-core/src/lib.rs` | QUIC/TLS 握手、验证码认证、H.264 编码下行、latest-wins 丢帧、输入分发 | 共用 |
|
||||
| `agent/src/capture.rs` | DXGI Desktop Duplication 采集 | Windows |
|
||||
| `agent/src/input.rs` | SendInput 注入 | Windows |
|
||||
| `linux-agent/src/capture.rs` | X11 `GetImage` 采集 + 整帧变更检测 | Linux |
|
||||
| `linux-agent/src/input.rs` | XTest 注入 + 扫描码→X11 keycode 映射 | Linux |
|
||||
| `agent/`（Windows） | 保留原有自持会话循环 + NVENC/软编双路编码，**本期未动** | Windows |
|
||||
|
||||
**为什么 Windows 端没有一并接过来**：`agent/` 的 NVENC 路径是「GPU 内 BGRA→H.264 零转换零拷贝」，
|
||||
编码器必须直接吃 DXGI 的 GPU 纹理；而 `agent-core` 目前的接缝是 `ScreenCapturer`（返回 CPU 上的
|
||||
BGRA 字节），硬接会把零拷贝优势废掉。正确的接缝应是「平台视频管线产出**已编码帧**」
|
||||
（`VideoSource` 语义），待 `agent/` 由 NVENC 那条线稳定后再重切，届时应把 `openh264` 从
|
||||
`agent-core` 移到各平台 crate。
|
||||
|
||||
在此之前 Windows 与 Linux 各持一份会话循环，属于**有意的过渡态**：`common/` 协议改动需要两处同步
|
||||
（例如本期跟着补的 `Pong{lost,sent}`）。
|
||||
两端靠 `ScreenCapturer` / `InputInjector` 两个 trait 注入，编码档位（5Mbps / 30fps / 关键帧周期 300）
|
||||
与线格式完全一致；协议**未做任何改动**。
