The way the internet pushes messages is very common, especially mobile Internet, mobile phone can receive a lot of push message every day, after research found that the principle of these push service is to maintain a long connection (or can not achieve real-time effect), but the normal socket connection to the server consumption is too large, So there's a lightweight, low-consumption protocol like MQTT to maintain long connections, so how to maintain

Description: MQTT is an instant Messaging protocol developed by IBM that is likely to be an important part of the Internet of things. The protocol supports all platforms, almost all connected items and external connections, and is used as a communication protocol for sensors and actuators (such as the Internet of homes via Twitter). Apache Apollo is a proxy server, which is developed on the basis of ACTIVEMQ, can support stomp, AMQP,

Brief introductionTsung is a stress testing tool that can test servers including HTTP, WebDAV, PostgreSQL, MySQL, LDAP, and Xmpp/jabber. For HTTP testing, Tsung supportsHTTP 1.0/1.1, which contains a proxy-mode session record, supports GET, POST and PUT, and DELETE methods, supports cookies and basic WWW authentication, and also supports SSL.How the Tsung Works(1) Each virtual user of Tsung is a lightweight process of Erlang. There is a big difference between this and LoadRunner.(2) The virtual
