SERVER OPERATING SYSTEM SUPPORTING DYNAMIC RECONNECTION OF USER TO MANY CLIENT SERVER SESSIONS AND LAST SESSION

PROBLEM TO BE SOLVED: To provide a server operating system that allows dynamic reconnection to sessions even when a user uses two different client computers.SOLUTION: An operating system includes a multiuser session manager and a multiuser stack protocol manager. When a user connects with a server through a first client, the stack protocol manager allocates a first protocol stack for the connection and the session manager generates a first session. When the user reconnects with the server using a second client that is different from the first client, the stack manager allocates a second protocol stack for the connection and starts generating a second session. The session manager recognizes that the user has relation with the first session; and adapts the first session to a system configuration of the second client.
