4. MQTT 与 NATS 对比

4.1 主题格式差异

功能	MQTT 主题	NATS 主题
节点注册	edgex/nodes/register	edgex.nodes.register
节点状态	edgex/nodes/{node_id}/status	edgex.nodes.{node_id}.status
设备报告	edgex/devices/report	edgex.devices.report
点位元数据上报	edgex/points/report	edgex.points.report
点位值同步	edgex/points/{node_id}/{device_id}	edgex.points.{node_id}.{device_id}
实时数据	edgex/data/{node_id}/{device_id}	edgex.data.{node_id}.{device_id}
心跳	edgex/heartbeat/{node_id}	edgex.heartbeat.{node_id}
命令响应	edgex/responses/{node_id}/{msg_id}	msg.Respond()

4.2 共同特性

1. 消息格式: 统一使用 {"header": {...}, "body": {...}} 结构
2. Header 字段: message_id, timestamp, source, destination, message_type, version, correlation_id
3. 设备聚合: 支持 periodic 和 realtime 两种推送策略
4. 命令处理: 支持 discover, write, task, register 等命令类型

---

5. 发现的问题

5.1 无严重问题

本次测试未发现需要修复的严重问题。所有消息格式正确，MQTT 和 NATS 客户端实现一致。

5.2 建议改进项

1. NATS 未配置: conf/northbound.yaml 中 edgeos_nats: [] 为空，建议添加 NATS 配置用于测试
2. 缺少端到端测试: 由于 EdgeOS 服务器端未运行，无法验证完整的注册握手流程
3. 监控指标: 建议添加 Prometheus 指标以便更好地监控通信状态

---

6. 测试结论

6.1 整体评估

维度	评估
MQTT 客户端	✅ 实现完整，功能正常
NATS 客户端	✅ 实现完整，单元测试全部通过
消息格式	✅ 符合协议规范
配置	✅ 配置正确，可启用

6.2 测试通过率

• 单元测试: 31/31 通过 (15 MQTT + 16 NATS)
• 集成测试: 7/7 通过 (MQTT 7项: 节点注册、设备报告、点位元数据上报、点位值同步、实时数据、心跳、控制命令)

6.3 建议

1. 下一步测试: 在 EdgeOS 服务器可用时进行完整的端到端测试
2. 性能测试: 建议在高数据量场景下测试设备聚合功能
3. 故障恢复: 建议测试网络断开重连场景
