1. User commences the IM client.2. IM client finds the IM server & logs in.3. It launches communication info (IP address, etc) to the IM server.4. IM server searches user's contacts & sends him/her the communication info.5. IM server also notifies the contacts which the user is online; sends his/her communication info to them.6. The user's & the contact's IM clients are prepared to communicate directly (P2P).7. As new contact has come online, IM server informs them about the user being online and many more.8. Multiple, real-time chat are possible.9. While the user logs-off, his/her IM client informs the IM server.10. IM servers wipes away the temporary file and inform the user's contact's about his/her ‘offline' status.
