You architecture will require a dedicated server in order to allow 2 machines to talk to each other (if both are behind the firewall).

Here we have to implement java client- server socket communication and client should be able to get their changing IPs according the network connected, and make new socket connection with changed IP.I have experience in similar work by implementing VOIP application in Java.

I would have to agree with "Softskyvw" who also bid on the project. A chat server will be needed to handle socket connections & routing since the client machines will no doubt have dynamic ip addresses. The clients would connect to the server and the server would negotiate the connections on their behalf. The chat server would also be able to keep track of who's on line, missed chat sessions and so on. Skype has a way to reduce the amount of servers required. Skype delegates much of the work to the PCs running their client software. Unless the PC is behind a firewall and using NAT Skype will use the CPU idle time to route calls. If you don't want to maintain tons server hardware the Skype model may be a solution. Or if you will have a limited number of clients there is probably an open source chat server that could be adapted to your needs and yes, there will still be a chat server. - John
