摘要: MQTT其独特的优点在物联网技术得到广泛应用，但服务器处理大量的请求时，MQTT服务器可能会出现宕机等问题，本文从优化负载均衡入手，对消息队列、CPU利用率、内存利用率的比重系数进行分析，利用新的权值计算方法，使系统负载更加均匀地分发至集群各服务器，总体平均响应时间更短，通过实验数据表明负载差能由原来的8%下降到4%左右，提高了MQTT服务器集群系统的使用效率，具有一定的实用价值。
Abstract: The unique advantage of MQTT is widely used in the Internet of things technology, but when the server processes a large number of requests, MQTT server may have downtime and other problems. This paper starts with optimizing the load balance, analyzes the proportion coefficient of message queue, CPU utilization and memory utilization, and uses the new weight calculation method, making the system load more evenly distributed to the cluster servers, and the overall average response time is shorter. The experimental data show that the load difference can be reduced from the original 8% to about 4%. It improves the efficiency of MQTT server cluster system and has a certain practical value.
