Question about session layer

xopito

I understand that the session layer is in charge of creating, maintaining and closing the communication between two end devices, however in some books says that the session layer adds the port number and the transport layer based on that, segment the data into tcp or udp. It is really confusing, can someone tell me if what I am saying is right or no?

Think of the session layer as an administrative assistant. It's duty is to keep it's executives (applications) on track and going to the right meetings/conferences/luncheons(sessions).

It keeps the calendar up to date by setting up meetings, canceling meetings when they are no longer needed and keeping track of all meetings that it's executives are currently involved in.
