Appl. No.:

12/306042

Assignee:

LANTRONIX, INC. - IRVINE CA

International Classification:

G06F 15/16
G06F 15/177

US Classification:

709222, 709227, 709231

Abstract:

A method, apparatus, and system are described for accessing networked devices without accessible network addresses via Virtual IP (VIP) addresses. The system consists of a first Device Services Controller (DSC), featuring a Host Controller component that can make available a virtual network interface and corresponding virtual IP address (VIP) and having a first conduit manager to create a first outgoing TCP/IP conduit connection to a device service manager (DSM). When networking traffic arrives at the virtual networking interface with the associated VIP, the Host Controller component automatically processes and forwards that traffic to the DSM. The DSM processes and relays traffic from the first outgoing TCP/IP conduitconnection to a second DSC, which has a Device Controller component and a second conduit manager to create a second direct outgoing TCP/IP conduit connection to the DSM. An IP redirector in the DSM receives communication traffic from the first established TCP/IP conduit connection from the first DSC and then routes the communication traffic down the second established TCP/IP conduit connection to the second DSC based on a Virtual IP address to real IP address mapping stored in the registry of the DSM. The Host Controller component processes and delivers the network traffic from the DSM to the appropriate local networked device and if appropriate send back any return traffic back to the DSM, which will return it to the first DSC for delivery to the originating network device, Using this mechanism, it is possible for two networked devices on separate networks to communicate even if there does not exist a route to the network address of the target device.

International Classification:

G06F 15/16

US Classification:

709245

Abstract:

A method, apparatus, and system are described for a central station to allocate virtual IP addresses. A device service manager server (DSM) has a network access module configured to cooperate with two or more device service controllers (DSCs). The DSM serves as a central management station for allocating and assigning Virtual IP addresses to network devices to proxy communications for networked devices on a local area network (LAN) where each DSC resides. The DSM is located exterior from the network devices on the LAN where communications associated with the assigned VIP addresses are being routed to. The DSM assigns a Virtual IP Addresses to each DSC and establishes a route from the assigned Virtual IP address to a destination network device on a LAN, based on corresponding DSC and network device information stored in a registry of the DSM.

Abstract:

A method, apparatus, and system are described for a central station to allocate virtual IP addresses. A device service manager server (DSM) has a network access module configured to cooperate with two or more device service controllers (DSCs). The DSM serves as a central management station for allocating and assigning Virtual IP addresses to network devices to proxy communications for networked devices on a local area network (LAN) where each DSC resides. In some embodiments, various protocols may use UDP broadcasts to perform device discovery.

The system processes and delivers the traffic to appropriate local networked device and sends back any return traffic to the DSM. The system allows for communication between networked devices on separate networks without direct network addresses.

Abstract:

A method, apparatus, and system are described for a central management system to configure remote devices. A device service manager server (DSM) may have an IP redirector module configured to cooperate with two or more device service controllers (DSCs) that are behind a firewall on a wide area network relative to a location of the DSM on the wide area network, where the DSM serves as a central management station for a distribution of initial configuration information to the DSCs, wherein an executable boot up file uploaded via a drive port in that DSC is scripted to gather configuration information for that DSC and network devices on the same network as that DSC and without a prompt by the DSM then sends configuration files to the DSM which makes a master copy of the device configuration file in the DSM's registry for that DSC.
