A research of the instant messaging system architecture based on Comet and Message Queue

In recent years, Internet is widely used in a variety of areas in the society. Web Applications that are base on B/S mode are much more convenient than Applications based on C/S mode, because they don´t need any clients. But, compared to B/S mode, C/S mode still has a great advantage in pushing instant messages to client from server. Consequently, How to implement pushing instant messages to web browser from web server based on B/S mode is becoming a hotter and hotter research focus. We use a technique that is called server-push to implement it. This paper will do an in-depth research into the Architecture of instant messaging system based on Comet and Message Queue.
