问题描述

我试图了解Amazon AWS IoT,并且看到在传感器/执行器和AWS(规则引擎)之间连接了一个设备网关.我了解传感器/执行器是MQTT客户端,可以发布/订阅主题.

I am trying to understand Amazon AWS IoT and I see there is a Device Gateway connected between Sensors/Actuators and AWS (Rules Engine). I understand Sensors/Actuators are MQTT Clients which can Publish/Subscribe to the topics.

设备网关也是MQTT客户端吗?

Device Gateway is also a MQTT Client ?

那MQTT经纪人在哪里?

Then where is the MQTT broker?

OR设备网关是AWS + IoT服务的代理+通信接口吗?

OR Device Gateway is Broker + communication interface to AWS-IoTservices?

我已在AWS IoT上附加了Image Amazon演示文稿作为参考:

I have attached an Image Amazon presentation on AWS IoT for the reference:

推荐答案

该网关是MQTT代理,但不是完全兼容的代理.一些区别是:

The gateway is a MQTT broker, but not a fully compliant one. Some of the differences are:

  • 不保留邮件支持
  • 不支持QOS2
  • 无消息持久性
