Abstract
A user at a remote computer is provided access to a computer network by a remote access device coupled to the network. The remote access device receives from the remote computer a username which uniquely identifies the user on the network. The remote access device then obtains an internet protocol (IP) address from a server on the network, which server dynamically assigns the IP address based on the username. The IP address uniquely identifies the remote computer on the network, and it is needed by the remote computer to communicate on the network. If the user at the remote computer disconnects, or is disconnected, from the network and then subsequently attempts to re-gain access to the network by sending the same username to either the same or a different remote access device coupled to the network, that remote access device obtains the same IP address from the server. The user at the remote computer thus is provided with the same IP address by the server on the network when the user disconnects and then later reconnects to the network even if each of the two connections is via a different remote access device.
