这篇文章讨论了几种模拟服务器推送的方法，从纯轮询到实时服务器推送，文中说明了每种方法的优缺点。
In this article, I discussed various approaches for simulating a server push, ranging from pure polling to a real-time server push, and noted the strengths and weaknesses of each approach.
考虑到这样两个问题，对于需要关键、实时的服务器端更新的企业应用程序而言，轮询并不是最理想的方法。
Given these two problems, polling may not be an appropriate approach for enterprise applications requiring critical, real-time, server-side updates.
该协议根据各节点内实时队列长度动态的控制轮询过程，每个轮询周期对具有最长队列的节点进行服务。
This protocol adaptively controls the polling process according to the real-time queue length of each stations and serves the one with the longest queue firstly in each polling cycle.
