二、模块详细设计

2.1 边端 Edge — server/edge/edge-node-manager.js

#### 设计目标

Offloads lightweight inference and preprocessing tasks from the cloud to edge nodes, reducing latency, saving bandwidth, and supporting offline scenarios.

#### Core Interfaces

| Function | Parameters | Returns | Description |

|---|---|---|---|

| registerNode(node) | {id, host, port, capabilities, location, weight} | node object | Register an edge node |

| unregisterNode(nodeId) | nodeId | void | Unregister a node |

| heartbeat(nodeId, stats) | nodeId, {taskCount, avgLatency} | bool | Heartbeat update |

| findBestNode(capability) | capability string | node/null | Find the optimal node |

| dispatch(capability, payload) | capability, payload | {nodeId, result, latency} | Dispatch a task to the edge |

| getNodes() | - | node list | Get all nodes |

| getStats() | - | statistics object | Get statistical information |

#### Node Selection Strategy

load = weight × (1 + taskCount) × (1 + avgLatency / 1000)
选择 load 最小的在线节点

#### 心跳机制

• Nodes send a heartbeat every 10s
• No heartbeat for over 30s → Marked as offline
• Offline nodes do not participate in task dispatch

#### Current Capability Mapping

const workerMap = {
  'spc_check':       () => require('../workers/spc-worker'),
  'qcc_inspect':     () => require('../workers/qcc-worker'),
  'data_preprocess': () => require('../workers/data-clerk'),
  'inspect':         () => require('../workers/inspect-worker'),
};

#### 扩展指南

1. Add new capability mappings in the workerMap
2. Replace _executeOnEdge with HTTP/gRPC calls in actual deployment:

   async function _executeOnEdge(node, capability, payload) {
     const resp = await fetch(`http://${node.host}:${node.port}/execute`, {
       method: 'POST',
       body: JSON.stringify({ capability, payload })
     });
     return resp.json();
   }
   

2.2 网端 Network — server/network/network-manager.js

#### 设计目标

Manages network connections between the management cloud/edge cloud, providing route selection, QoS assurance, and message reliability.

#### Core Interfaces

| Function | Parameters | Returns | Description |

|---|---|---|---|

| registerLink(linkId, config) | linkId, {from, to, bandwidth, latency, reliability, cost} | link object | Register a network link |

| unregisterLink(linkId) | linkId | void | Unregister a link |

| selectRoute(from, to, opts) | from, to, {priority, maxLatency, minBandwidth} | link/null | Route selection |

| send(link, payload, opts) | link, payload, {timeout, retry} | {success, roundTrip, result} | Send a message |

| createConnection(connId, config) | connId, {from, to, type, onMessage} | conn object | Establish a persistent connection |

| getTopology() | - | topology object | Get network topology |

| getStats() | - | statistics object | Get network statistics |

#### Route Selection Formula

score = (bandwidth × reliability × qosLevel) / (latency × cost)
选择 score 最高的活跃链路

QoS级别：high=3, normal=2, low=1

#### Message Reliability

• Automatic retry (default 3 times, exponential backoff)
• Timeout control (default 30s)
• ACK confirmation (tracked via success/failed statistics)
• Transmission failure simulation (based on reliability probability)

#### Extended Guide

1. Replace _transmit with real network transmission in actual deployment:

   async function _transmit(link, payload, timeout) {
     const controller = new AbortController();
     setTimeout(() => controller.abort(), timeout);
     const resp = await fetch(`http://${link.to}/receive`, {
       method: 'POST',
       body: JSON.stringify(payload),
       signal: controller.signal
     });
     return resp.json();
   }
   

1. 添加WebSocket支持用于实时消息
2. 添加消息加密（TLS/自定义加密）

2.3 A2A/MACP 协议 — server/boss-scheduler/a2a-protocol.js

#### A2A (Agent-to-Agent) — 员工间点对点通信

| Function | Description |

|---|---|

| sendMessage(from, to, content) | Send point-to-point message |

| broadcast(from, targets, content) | Broadcast to multiple staff members |

| requestCollaboration(from, result, config) | Automatically trigger downstream based on collaboration configuration |

| getMessages(staffId, opts) | Retrieve staff message history |

#### MACP (Multi-Agent Communication Protocol) — Multi-Agent Session

| Function | Description |

|---|---|

| createSession(participants, context) | Create a multi-agent session |

| sendInSession(sessionId, from, content) | Send message within session (automatically broadcast to other participants) |

| closeSession(sessionId) | Close session |

| listActiveSessions() | List active sessions |

#### Automatic Trigger Mechanism

After completing a task, runStaffOnce automatically checks the staff.collaboration.onComplete configuration:

// boss-scheduler/index.js runStaffOnce
const result = await scheduler.runOnce(staffId, intent, parameters);
const staff = staffList.find(s => s.id === staffId);
if (staff && staff.collaboration && result) {
  a2a.requestCollaboration(staffId, result, staff.collaboration);
}

2.4 人侧 Human — taskForces gate 节点

在 local.yaml 的 taskForces 中定义，gate 节点为人工审批：

taskForces:
  - id: TF-COMPLAINT
    members:
      - key: gate
        type: human          # 人侧节点
        role: 质量经理放行审批
        approver: 质量经理
        dependsOn: [proc, sched]
        gate:
          question: 是否批准该整改方案并放行受影响批次？
          options: [批准放行, 有条件放行, 驳回重做]

当前4个taskForce共有4个人侧gate节点：

• TF-COMPLAINT: Quality Manager Release
• TF-LINE-STOP: Workshop Director Resumption Decision
• TF-NEW-PRODUCT: Technical Director Review
• TF-COST-ALERT: No Gate (Fully Automatic)

四、部署指南

4.1 云端部署（当前已运行）

# 启动云端服务器
cd C:\bossagents
node server.js  # 默认端口 3006

4.2 边端部署

#### 方式一：本地模拟（开发/测试）

No additional deployment required; the _executeOnEdge method in edge-node-manager.js directly calls the local worker.

#### Method 2: Independent Edge Node (Production)

1. Deploy a lightweight Node.js service on the edge machine:

   // edge-server.js (边缘节点上的服务)
   const http = require('http');
   http.createServer((req, res) => {
     // 接收云端分派的任务并执行
   }).listen(8081);
   

1. 在云端注册边缘节点：

   curl -X POST http://cloud:3006/api/edge/nodes \
     -H 'Content-Type: application/json' \
     -d '{"id":"edge-01","host":"192.168.1.100","port":8081,"capabilities":["spc_check","qcc_inspect"]}'
   

1. 注册网络链路：

   curl -X POST http://cloud:3006/api/network/links \
     -H 'Content-Type: application/json' \
     -d '{"linkId":"cloud-edge-01","from":"cloud","to":"edge-01","bandwidth":100,"latency":5,"reliability":0.99}'
   

4.3 网端配置

网端为云端内置模块，无需独立部署。通过API注册链路即可建立端云/边云连接。

4.4 Human-Side Configuration

Define the gate node in the taskForces section of local.yaml; no additional deployment required.

2. Implement the corresponding worker file
3. Declare in capabilities when registering the edge node

#### Scenario 2: Adding a New Collaboration Link

1. Add collaboration.onComplete configuration under the corresponding employee in local.yaml
2. Run node scripts/sync-collab-to-db.js to sync to DB
3. Restart the server

#### Scenario 3: Adding a New Human-Side Approval Node

1. Add a member with type: human in the taskForces section of local.yaml
2. Set gate.question and gate.options

#### Scenario 4: Replacing with Real Network Transmission

1. Modify _executeOnEdge in edge-node-manager.js → HTTP call
2. Modify _transmit in network-manager.js → HTTP/WebSocket call
3. Deploy corresponding server on edge nodes

5.4 Verify Command

# 验证5端协同状态

# 注册边缘节点
curl -X POST https://ylxt.chat/api/edge/nodes -H 'Content-Type: application/json' -d '{"id":"edge-01","host":"localhost","port":8081,"capabilities":["spc_check"]}'

# 查看网络拓扑
curl https://ylxt.chat/api/network/topology

5.5 注意事项

1. edge-node-manager.js 有两份：server/edge/ 和 server/boss-scheduler/edge/，前者被直接引用，后者通过boss-scheduler导出。修改时两份都要改，或统一引用路径。
2. 心跳定时器：edge-node-manager.js 的心跳检测使用 setInterval，在测试脚本中需调用 edge.stop() 清理。
3. A2A消息队列：当前为内存存储（最大1000条），重启后清空。生产环境需替换为持久化存储。
4. network模拟传输：_transmit 当前为模拟（基于latency延迟+reliability概率失败），生产部署需替换为真实网络调用。
5. type过滤：staff-router.js 的 matchStaff 过滤非 digital_worker 类型，新增面向用户的员工需确保 type 为空或 digital_worker。
