摘　　要：当前消息推送已成为网络消息传递的一种主流方式,特别在移动平台上得到广泛应用,淘宝、QQ及微信等大型交流平台都使用消息推送方式。在Linux系统下的Epoll模型是一种优秀的通信模型,它优于Select模型和Poll模型,在连接数量上限制很小,并且对CPU的负担比较小。文章基于Epoll模型和长连接方法设计一种新的消息推送方法,并与国际流行的消息推送方法进行对比仿真实验,实验结果表明,基于Epoll模型的消息推送方法在及时性与连接数量耗时上均优于传统的方法。At present, the message push has become a major way of the network messaging, and has been widely implemented by many large communication platforms, such as Taobao, QQ and WeChat, especially the mobile platform. In the Linux system, Epoll model is an excellent communication model which is superior to Select and Poll models, it has a small limit on the number of connections and its b,urden on the CPU is very small. In this paper, a new message push method is designed by using the Epoll model and long connection method. Then the designed method is compared with internationally popular methods and the results show that the method based on Epoll model is better than traditional methods in the timeliness and the number of connections.
