Remote reconfiguration of a secure network interface
First Claim
1. A method of reconfiguring a network interface device coupled between a first network and a second network, said method comprising:
- associating a first time window with a reconfiguration notification message;
initiating reconfiguration of the network interface device by a remote server; and
sending said reconfiguration notification message to said network interface device if said network interface device is eligible for reconfiguration, wherein said reconfiguration notification message is sent through a public key/private key encryption mechanism established between said remote server and said network interface device.

Abstract
The present invention discloses a initializing and reconfiguring a network interface device connecting a client computer system to an external network. The network interface device is configured for the client system by automated procedures and protocols initiated from a remote server. Software programs within the network interface device provide transparent communication between the client computer system and services available on the external network. Similar software programs and a configuration database within the network interface device provide transparent communication between the client computer system and the remote server.

1. A method of reconfiguring a network interface device coupled between a first network and a second network, said method comprising:
-
associating a first time window with a reconfiguration notification message;
initiating reconfiguration of the network interface device by a remote server; and
sending said reconfiguration notification message to said network interface device if said network interface device is eligible for reconfiguration, wherein said reconfiguration notification message is sent through a public key/private key encryption mechanism established between said remote server and said network interface device. - View Dependent Claims (2, 3, 4, 5)
upon receipt of said reconfiguration notification message and within the time specified by said first time window, said network interface device writes said replacement data parameters to corresponding data entry locations within said database.
-
-
4. The method of claim 3 further comprising:
-
determining, in said network interface device, whether the writing of said replacement data parameters was successful;
transmitting, from said network interface device, a first notification message to a server if reconfiguration was successful; and
transmitting, from said network interface device, a second notification message to said server if said reconfiguration was not successful.
-
-
5. The method of claim 2 wherein said reconfiguration notification message is transferred through a public key/private key encryption mechanism established between a server and said network interface device.
-
6. An article of manufacture embodying a program of instructions executable by a machine for reconfiguring a network interface device coupled between a first network and a second network, the program of instructions including instructions for:
-
associating a first time window with a reconfiguration notification message;
initiating reconfiguration of the network interface device by a remote server; and
sending said reconfiguration notification message to said network interface device if said network interface device is eligible for reconfiguration, wherein said reconfiguration notification message is sent through a public key/private key encryption mechanism established between said remote server and said network interface device. - View Dependent Claims (7, 8)
programming said reconfiguration notification message with replacement data parameters for modification of data entries stored in a database within said network interface device;
writing said replacement data parameters to corresponding data entry locations within said database upon receipt of said reconfiguration notification message and within the time specified by said first time window.
-
-
8. The article of manufacture according to claim 7, wherein said program of instructions further includes instructions for:
-
determining, in said network interface device, whether the writing of said replacement data parameters was successful;
transmitting, from said network interface device, a first notification message to a server if reconfiguration was successful; and
transmitting, from said network interface device, a second notification message to said server if said reconfiguration was not successful.
-
-
9. A method of upgrading software on a network interface device coupled between a first network and a second network, the method comprising:
-
identifying a first time window and a second time window for an upgrade notification message;
determining whether the network interface device is a part of a virtual private network (VPN);
if the network interface device is the part of the VPN, sending the upgrade notification message to a headquarters branch of the VPN, wherein the upgrade notification message directs the headquarters branch to retrieve an upgrade package from a remote site specified in the notification message within the first time window and further directs each node within the VPN to upgrade software at any time within the second time window. - View Dependent Claims (10, 11, 12)
determining that the network interface device is not a part of the virtual private network;
retrieving an upgrade package from a remote site specified in the notification message any time within the first time window; and
upgrading software on the network interface device using the upgrade package at any time within the second time window.
-
-
12. The method of claim 9 further comprising:
-
determining that all nodes of the VPN have accepted the upgrade;
retrieving an upgrade package from a remote site specified in the notification message any time within the first time window;
sending the upgrade package to each node within the VPN; and
performing the upgrade of the VPN at any time within the second time window.

-
13. A system comprising:
-
a first network;
a second network;
a network interface device coupled between the first network and the second network; and
a server coupled to the first network and the network interface device, the server configured to initiate reconfiguration of the network interface device and to provide reconfiguration information to the network interface device if the network interface device is eligible to receive the reconfiguration information, wherein said reconfiguration notification message is sent through a public key/private key encryption mechanism established between a remote server and said network interface device, the reconfiguration information being associated with a first time window. - View Dependent Claims (14, 15, 16, 17)
determine whether the writing of said replacement data parameters was successful, transmit a first notification message to the server if execution of a reconfiguration program was successful, and transmit a second notification message to the server if execution of the reconfiguration program was not successful. -
17. The system of claim 14 wherein the reconfiguration information is transferred through a public key/private key encryption mechanism established between the server and the network interface device.

18. A system comprising:
-
a first network;
a second network;
a network interface device coupled between the first network and the second network; and
a server coupled to the first network and the network interface device, the server configured to identify a first time window and a second time window for an upgrade notification message, to determine whether the network interface device is a part of a virtual private network (VPN) and, if the network interface device is the part of the VPN, to send the upgrade notification message to a headquarters branch of the VPN, wherein the upgrade notification message directs the headquarters branch to retrieve an upgrade package from a remote site specified in the upgrade notification message within the first time window and further directs each node within the VPN to upgrade software at any time within the second time window. - View Dependent Claims (19, 20, 21, 22)
