Motivation
A social networking site that allows you to
video chat online is the primary inspiration for
my project.
 I am highly interested in the development of
Network Application.
 I have interest in Socket programming .
 This application covers my all area of interest.

Overview of chat application




There are so many chat application exists, but most of
them are server/client based application. User have to
make profile to user those application
To use Video On LAN Application user do not have to
make profile page. Just need to add IP address.
To initiate chat with user it requires users acceptance.
IP addresses are saved in contact log file to next time
you start the chat you do not have to add IP address.
Technology
