The Session Layer
If you are an ardent user of the Yahoo Messenger or any messenger for that matter and if you are popular among you friends, I am sure you would have faced the crisis of replying to several message windows popping up on your screen. Imagine the complexity of the software (yahoo messenger for ex), it has to cater to serveral connections at the same time. Each window is a connection, the front end (the blank space where you type your message) is the application layer, the smiley's and italics that you conjure up are displayed on the window at the receiving end through the presentation layer and each session is maintained by the session layer.
Every time you open a new chat window the session layer sets up the connection to the yahoo server and any message received for the window is forwarded to the appropriate window or in other words session layer manages the connections and when the window is closed it tears down the connection. If the messenger has a buggy session layer application I shudder to think about the plight of the messenger user, messages meant for one person might end up in the window of another( I hope you got the picture).
that is possible by ip .how can you explain ?
