Abstract: Methods and systems are provided for a transportation vehicle. One method includes determining current available bandwidth rate based on network traffic generated by a plurality of devices and a plurality of traffic types on a transportation vehicle; utilizing a hierarchical tree structure to modify quality of service (QoS) that is indicated by a specific bandwidth rate associated with different priority levels, where each priority level is associated with one of the plurality of devices and the plurality of traffic types; and storing the modified QoS for the different priority levels at the hierarchical tree structure for a next update of the QoS when the current available bandwidth rate changes.

Abstract: A system for identifying a wireless security threat on a vehicle. The system includes a broadband controller including a data processor and memory in which the broadband controller provides a network within the vehicle. The system includes a vehicle WAP in communication with the broadband controller in which the WAP broadcasts an SSID for use by a PED to establish a wireless communication link and transmit and receive data wirelessly over the network via the WAP. An SSID scanner periodically scans for SSIDs broadcast in the vehicle in which SSIDs detected during scans are communicated to the broadband controller. For a detected SSID corresponding to the vehicles WAP SSID, logic executed by the data processor compares the BSSID of the vehicle WAP with the BSSID from the detected SSID and if the BSSIDs do not match, the logic identifies a security threat.

Abstract: Methods and systems for a transportation vehicle are provided. For example, one method includes capturing a video for a public announcement at a transportation vehicle by an authorized device, where metadata of the video identifies the video for public announcement; transmitting the video to a distribution device that recognizes the video as being for public announcement; pausing distribution of any other video; selecting the video for public announcement; and distributing the video for public announcement to user devices at the transportation vehicle.

Abstract: A high availability backplane architecture. The backplane system includes redundant node boards operatively communicating with redundant switch fabric boards. Uplink ports of the node boards are logically grouped into trunk ports at one end of the communication link with the switch fabric boards. The node boards and the switch fabric boards routinely perform link integrity checks when operating in a normal mode such that each can independently initiate failover to working ports when a link failure is detected. Link failure is detected either by sending a link heartbeat message after the link has had no traffic for a predetermined interval, or after receiving a predetermined consecutive number of invalid packets. Once the link failure is resolved, operation resumes in normal mode.

Abstract: A method for actively detecting link failures on a high availability backplane architecture. The backplane system includes redundant node boards operatively communicating with redundant switch fabric boards. Uplink ports of the node boards are logically grouped into trunk ports at one end of the communication link with the switch fabric boards. A probe packet is sent, and a probing timer is set whenever either a specified number of bad packets are received, or an idle timer expires. If a response to the probe packet is received before the probe timer expires then the link is deemed valid, otherwise the link is presumed to have failed. Preferably, either the node boards or the switch fabric boards are configured to properly handle a probe pack, which preferably has identical source and destination addresses.

Abstract: A network switch includes a plurality of ports, a packet engine for transferring incoming packets to an appropriate outgoing port dependent on a destination address carried in said packet, and a switching database providing switching information to said packet engine, said switching database comprising a low speed main database and a high speed cache, and a controller for transferring switching data between said database and said cache in accordance with a predetermined control policy.
