Abstract: A method is present for transferring information in an aircraft network data processing system. A message is received from a process executing on the aircraft network data processing system for a destination to form a pending message. The pending message is received using a common protocol for processes executing in the aircraft network data processing system. A communication service is identified from a number of communication services for use in sending the message to the destination remote to the aircraft network data processing system to form a selected communication service in response to receiving the pending message. A new message is formed from the pending message. The new message has a format usable by an associated protocol for the selected communication service. The new message is sent to the destination using the selected communication service.

Abstract: Configuration of hardware and software onboard a mobile platform may be dynamically managed without significantly impacting a data stream from the mobile platform. Configuration data for equipment and resident software aboard a mobile platform is electronically reported in the form of a part number and a serial number. The configuration data is transferred to a terrestrial database via a mobile communications network. The configuration data is displayed to stakeholders, such as the network-provider enterprise and its customers. Invalid configurations may cause alerts.

Abstract: A status reporting system for components used in a mobile platform includes a fault manager within the mobile platform for assigning a state indicator to each component. Each state indicator indicates the operational current state of the component. A management system external to the mobile platform, in one example being a ground based management system, is in communication with the mobile platform via a wireless communication link. A component summary including the state indicators of all the components is periodically transmitted from the mobile platform as an information packet, via the wireless link, to the management system for review. The management system can thus remotely monitor the operational status of various important components on a periodic basis, for example every five minutes. This saves significant bandwidth over that which would be required if a continuous wireless link was to be employed to remotely monitor various components on the mobile platform.

Abstract: Exemplary methods and systems manage a mobile network. A mobile network node is managed when the node is connected to the network. However, an alarm is not necessarily generated when the node is not connected to the network. A status message is periodically generated and transmitted from the mobile network node to a network control facility. The status message may include any status information regarding the mobile network node as desired. When the status message is indicative of a predetermined condition, an alarm is automatically generated. When no status message is received from the mobile network node, a determination is made whether connectivity exists between the mobile network node and the network. If connectivity does not exist between the mobile network node and the network, then no alarm is generated. If connectivity does exist between the mobile network node and the network, then an alarm is generated.

Abstract: A communications system that provides broadband access to passengers of mobile platforms includes a router located on the mobile platform. A network is connected to the router. User communication devices (UCDs) connected to the network, wherein the UCDs establish point-to-point over Ethernet (PPPoE) sessions with the router. A transmitter and a receiver are connected to the router. A satellite and a ground station are in communication with the transmitter and the receiver. A distributed communications system includes virtual private networks (VPN) and is connected to the ground station. A first address manager leases the use of public IP addresses by the mobile platform. A second address manager assigns the public IP addresses to UCDs when the UCDs request access to the VPNs and private IP addresses for other network service. The UCDs employ IPSec protocol when accessing the VPNs.

Abstract: A method for assigning Internet Protocol addresses in a communications system for an aircraft according to the invention includes the steps of creating an air-to-ground network (AGN), a passenger services network (PSN), and a command and control network (CCN). A first range of addresses is assigned to a first group of devices that are associated with the AGN. A second range of addresses is assigned to a second group of devices that are associated with the PSN. A third range of addresses is assigned to a third group of devices that are associated with the CCN. IP aliasing is employed to allow at least one device from the first, second and third groups to be multi-homed.

Abstract: An Internet protocol (IP) networking architecture includes a command and control sub-network (CCN) interconnecting a plurality of control interfaces wherein each control interface has a corresponding logical CCN address. A passenger services sub-network (PSN) interconnects a plurality of passenger interfaces wherein each passenger interface has a corresponding logical PSN address. The architecture further includes an air-to-ground sub-network (AGN) providing Internet access to the passenger interfaces via one or more isolation systems having corresponding logical CCN address and corresponding logical PSN address. By providing the isolation systems with multiple logical addresses, devices communicating on the AGN and PSN can be blocked from accessing the CCN addresses.

Abstract: A method for controlling the data rate of a virtual connection. Data packets are received for transmission on the virtual connection. The method comprises buffering the data packets in a buffer. A counter signal is generated to indicate the beginning of timeslots in a measurement window. The number of timeslots needed to transmit the data packets with a selected data rate is determined. The method further accesses data from at least one table to determine the spacing between timeslots in the measurement window used to request access to a data bus based on the number of timeslots needed to achieve the selected data rate. Further, access to a data bus for the data packets in the buffer is requested based on the data accessed from the table. The method further transmits the packets when access to the bus is granted.

Abstract: A system and method for protection of virtual connections at the data link layer. The method provides for protection switching in a ring network. The method comprises detecting an error in one of a first and second routes (“the errored route”). Error cells are generated for each virtual connection affected by the detected error. Error cells are transmitted downstream on the errored route. First switch fabric receives the error cells at a downstream network element associated with the errored route. Change in state of the errored route is communicated to a second switch fabric of the downstream network element associated with the other of the first and second routes (the “other route”). When the state of the errored route is worse than the state of the other route, automatically configuring the second switch fabric to establish the other route to be a working route for the virtual connection.

Abstract: The firearm safety device includes a cylindrical cartridge plug which is insertable into a firing chamber of the barrel of a firearm. One end of the cartridge plug is positioned proximal to the opening of the bore through the barrel and the other end is positioned proximal to a firing pin of the firearm. The cartridge plug has a smooth outer surface which is in communication with an extraction finger of the firearm. A number of protrusions emanate outwardly from the outer surface of the cartridge plug. The protrusions are frictionally engageable with the inner wall of the firing chamber to maintain the plug within the firing chamber. An elongated indicator member is connected to the end of the cartridge plug which is proximal to the bore. The other end of the elongated indicator member extends completely through the bore of the barrel so that it is visible outside the barrel of the firearm to indicate to the user that the firearm is in a safe condition and cannot be fired.

Abstract: A system and method for routing IP packets to an aircraft eliminates the need for the exchange of routing information via dynamic routing protocols between the aircraft and ground station routers. An Internet protocol (IP) packet routing table is populated by converting a tail number of the aircraft into a destination subnet address for the aircraft. Forward channel information for a ground router is determined based on the tail number. The method further provides for adding a route entry to the routing table based on the forward channel information and the destination subnet address such that the route entry enables the ground router to delivery IP packets to the aircraft.
