About Jitsi architecture

I want to know the process of Jitsi will work when people want to host a online conference. What component will be called and role of component in the process? Thank you.

The minimal architecture is composed of:

  • web server: hosts the web assets
  • prosody: XMPP server which Jitsi uses for signalling
  • jicofo: confernce focus, allocates channels in the JVBs for a conference to take place
  • jvb: media router
