Openfire

Openfire (formerly Wildfire) is a real time collaboration (RTC) server dual-licensed under the Open Source GPL and commercially. It uses the only widely adopted open protocol for instant messaging, XMPP (also called Jabber). Openfire is incredibly easy to setup and administer, but offers rock-solid security and performance.

web im的架构设想

利用openfire及其connection manager实现大容量web im的架构设想

蓝色的箭头是发送，红色的是接收
利用connection manager来实现multiplex
每个IM用户用一个WebIMSession来保存会话信息
到openfire之间连接很少，通常5个
收到消息之后通过WebIMSession定位到用户，触发ajax listener到界面弹出信息
瓶颈在web ajax connections / web server
