Dynamic mapping of user id into TCP/IP address without user interaction as user signing on or singing off among workstations

摘要

Method, apparatus and system is disclosed for providing TCP/IP addresses from a dynamic user identification server to workstations running an application program so that messages can be sent from one operator to another operator regardless of which workstation the other operator may be using, without the need to send the message itself through a server station. The dynamic user identification server also keeps track of the number of workstations in use at any one time and the number of copies of a licensed program being used for royalty control.
