基于MQTT的企业消息推送系统

消息推送系统在实现企业办公自动化方面有着重要的作用,通信协议和系统架构的设计是企业消息推送系统性能优化的关键因素.传统的标准化协议方案在移动互联网领域的应用存在着实现复杂和流量消耗大等缺点.针对这一问题,结合企业消息推送系统的特点,采用物联网领域的轻量级协议MQTT来设计企业消息推送系统的通信协议,通过设计MQTT话题区分社交通知、即时消息和状态呈现等功能,在满足了应用需求的同时保证了协议的简单易实现和流量消耗小等适用于移动互联网的优势.另一方面,在传统的对称和非对称设计的服务器架构之上,提出了信息上非对称和功能上对称的系统架构,为企业消息推送系统的构建提供了一个详细的解决方案.该方案在满足系统设计需求的同时提高了系统的可扩展性.

Enterprise Push Notification System Based on MQTT

Push notification system plays an important role in the implement of enterprise office automation. And communication protocol and system architecture have become the main factors in the performance optimize of enterprise push notification system. Traditional standardized protocol scheme has encountered problems such as too complex to implement and huge traffic cost in mobile internet. This paper, for the stated problem and the features of enterprise push notification system, designed a communication protocol based on MQTT, a lightweight protocol in Internet of Things, and partitioned social network notification, instant messaging and presence by the design of MQTT topics. The new designed protocol is easy to implement and small traffic cost. On the other hand, this paper, based on the traditional symmetric and asymmetric system architecture, proposed a system architecture which is asymmetric on information and symmetric on function, by which supplied a detailed solution for push notification system for enterprise. This solution can meet the requirements of system design as well as improve the scalability of the system.
