    摘要: A client device establishes a virtual private network connection with a central site or network through a master concentrator. The master concentrator transmits state information, relating to the virtual private network connection, to a backup concentrator. In the event the master concentrator fails during a communications session between the client device and the network, the backup concentrator maintains the communication session between the client device and the network over the virtual private network connection using the connection state information received from the master concentrator. Such a configuration allows for failover of a virtual private network connection from the master concentrator to the backup concentrator without requiring the client device to re-establish the virtual private network connection with the central site or network. The configuration also allows the client device to maintain an existing communications session with the network.

    摘要: In a hardware client for remote logon to a network, a two layer authentication protocol enables authorized users to log on while discouraging unauthorized users. The hardware client prevents logging on to the network if the hardware client is stolen. The hardware client itself is authenticated in the first authentication layer in order to establish a link to the network. Then a client computer authenticates in a second layer and further establishes a secure connection to the network. If the power of the hardware client goes off (as it would if or example it were unplugged for transport), then the authentication is not saved and therefore is lost. The hardware client must be reauthenticated before it can be used again.
