Why inter-process communication is requiredThe realization of complex business system has two kinds of relative realization idea, one is to do a chatty program, this program is all tube, completely realizes all functions of the business system, second, the complex system is decomposed into a series of function points, then corresponding to do multiple programs to jointly realize the overall function. The latter idea is the embod

Edit the Mosquitto configuration file Mosquitto-auth-plug has a variety of sample configuration files in the source code, you can use these files. For example, I use MySQL to verify that you can use the mosquitto-mysql.conf in the examples directory. MV Mosquitto.conf Mosquitto.conf.origin (retains the original configur

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

Strictly speaking, MQTT has little to do with WebSocket. They are not at a level.The relationship between Mqtt and TCP, WebSocket can be used at a glance:Resources:http://www.zhihu.com/question/21816631Advantages of WebSocketPreviously, many websites used polling to implement push technology. Polling is at a specific time interval (for example, 1 seconds), the browser sends an HTTP request to the server, an

timely implementation of the message line and real-time.3. Message Push Solution OverviewA, C2DM Cloud Push ProgramOn the Android phone platform, Google offers C2DM (cloudto Device messaging) services. The Android Cloud to Device messaging (C2DM) is a service that helps developers send data from the server to the Android application. The service provides a simpl

, make a mobile phone, they may remove such services as Google, especially in China, and remove native services such as Google. If you have bought some hosts such as a cottage or Huawei, Google's services may be unavailable. For example, those who go abroad may be built in. With these constraints, I finally gave up this solution, however, I want to use another article to introduce the C2DM framework in detail and the corresponding setting methods of the client and App Server, which can be used

like those out there might be built in.With the above constraints, I finally gave up the plan, but I would like to use another article to describe in detail the framework of C2DM and the corresponding settings of the client and app server, can be used as a learning resource to let us have a reference material. If C2DM does not meet our requirements, then we need to implement the communication protocol between the Android phone client and the app serv
