How does IP messenger work?

Well, it uses Java Socket Programming to perform the above mentioned tasks.

Wanna know more? Well, it creates a multicast object and uses the methods like InetAddress.getByName() and other similar other methods to meet its ends. You can search for the InetAddress class to get more info 😁 .

Still want more? As this software is open source, u too can check the code for urself!! 😎 and ask any difficulties u face here.

Still got some doubts? You can ask us and we would be happy to help!👍

Thanxx for the rply.....but i actually dont want to get into the coding part.....i want to understand it frm the TCP/IP point of view....as to how it works at the layer level???😀

I think it happens in the following manner:

• When the software starts, it broadcasts the packet to all computers on the Lan and those which have same software running responds.
• Thus it gets a list of active users as hostnames are received as the response by the other computers.
• Then it calculates the IP Addresses from the hostnames using getbyname() function told above.
• The chat server starts running on a predetermined port to address the communication.

The software uses multithreading to handle different operations separately.
Hope it answers your query!😀

thanks a lot man.....the above info was really helpful...
