Abstract

Methods and systems for a transportation vehicle are provided. One method includes generating a packet by an application executed by a processor of a first seat device of an in-flight entertainment system having a plurality of seat devices on an aircraft; dropping the packet by the seat device when the application is not authorized for Internet communication; dropping the packet by the seat device when the packet is one of a broadcast packet, multicast packet or destined to a second seat device of the in-flight entertainment system; determining that the seat device Internet traffic is below a threshold value; and transmitting the packet to a network device when the application is authorized, and the packet is not a broadcast packet, multicast packet or destined for a second seat device.

First claim

What is claimed is:

1. A method comprising:
receiving a packet by a server interfacing with a plurality of seat devices of an in-flight entertainment system of an aircraft via a network device;
determining whether the received packet belongs to a network communication initiated by a first seat device;
dropping the received packet by the server when the received packet is not part of the network communication;
dropping the received packet by the server when the received packet is a certain type;
dropping the received packet by the server when combined bandwidth usage by the plurality of seat devices has reached a first threshold value or when bandwidth usage by the first seat device has reached a second threshold value, wherein the first threshold value and the second threshold value are configurable and stored in a data structure accessible by the server, the first threshold value configured to control bandwidth usage of the aircraft and the second threshold value configured to control bandwidth usage of the first seat device;
forwarding the received packet to the first seat device when the first threshold and the second threshold values have not been reached, the received packet has not been dropped based on packet type and the received packet is received in response to network communication initiated by the first seat device;
generating an egress packet by an application executed by a processor of the first seat device;
dropping the egress packet by the first seat device when the application is not authorized for Internet communication;
dropping the egress packet by the first seat device when the egress packet is one of a broadcast packet, a multicast packet or destined to a second seat device; and
in response to determining that the first seat device Internet traffic has not reached the second threshold value, transmitting the egress packet to the network device when the application is authorized and the egress packet is not the broadcast packet, the multicast packet or destined to the second seat device.

2. The method of claim 1 , wherein the received packet is dropped when the received packet is one of a secure shell and an Internet Relay Chat packet.

3. The method of claim 1 , wherein the network communication is transmission control protocol (TCP) communication initiated by the first seat device.

4. The method of claim 1 , wherein when the received packet is a pre-configured, multicast packet, the received packet is forwarded to the plurality of seat devices.

5. The method of claim 1 , wherein the server transmits any user datagram protocol packet generated by the first seat device.

6. The method of claim 1 , wherein the server transmits any Internet Control Message Protocol packet generated by the first seat device.

7. A non-transitory, machine readable storage medium having stored thereon instructions for performing a method, comprising machine executable code which when executed by at least one machine, causes the machine to:
receive a packet by a server interfacing with a plurality of seat devices of an in-flight entertainment system of an aircraft via a network device;
determine whether the received packet belongs to a network communication initiated by a first seat device;
drop the received packet by the server when the received packet is not part of the network communication;
drop the received packet by the server when the received packet is a certain type;
drop the received packet by the server when combined bandwidth usage of the plurality of seat devices has reached a first threshold value or when bandwidth usage by the first seat device has reached a second threshold value, wherein the first threshold value and the second threshold value are configurable and stored in a data structure accessible by the server, the first threshold value configured to control bandwidth usage of the aircraft and the second threshold value configured to control bandwidth usage of the first seat device;
forward the received packet to the first seat device when the first threshold and the second threshold values have not been reached, the received packet has not been dropped based on packet type and the received packet is received in response to network communication initiated by the first seat device;
generate an egress packet by an application executed by a processor of the first seat device;
drop the egress packet by the first seat device when the application is not authorized for Internet communication;
drop the egress packet by the first seat device when the egress packet is one of a broadcast packet, a multicast packet or destined to a second seat device; and
in response to determining that the first seat device Internet traffic has not reached the second threshold value, transmit the egress packet to the network device when the application is authorized and the egress packet is not the broadcast packet, the multicast packet or destined to the second seat device.

8. The non-transitory machine readable storage medium of claim 7 , wherein the received packet is dropped when the received packet is one of a secure shell and an Internet Relay Chat packet.

9. The non-transitory machine readable storage medium of claim 7 , wherein the network communication is transmission control protocol (TCP) communication initiated by the first seat device.

10. The non-transitory machine readable storage medium of claim 7 , wherein when the received packet is a pre-configured, multicast packet, the received packet is forwarded to the plurality of seat devices.

11. The non-transitory machine readable storage medium of claim 7 , wherein the server transmits any user datagram protocol packet generated by the first seat device.

12. The non-transitory machine readable storage medium of claim 7 , wherein the server transmits any Internet Control Message Protocol packet generated by the first seat device.

13. The non-transitory machine readable storage medium of claim 7 , wherein the machine executable code which when executed by at least one machine, further causes the machine to: drop the received packet by the server when bandwidth usage by the first seat device has reached the second threshold value.

14. A system, comprising:
a server interfacing with a plurality of seat devices of an in-flight entertainment system of an aircraft via a network device, the server having a memory containing machine readable medium with machine executable code having stored thereon instructions; and a processor coupled to the memory, to execute the machine executable code to:
receive a packet by a server interfacing with a plurality of seat devices of an in-flight entertainment system of an aircraft via a network device;
determine whether the received packet belongs to a network communication initiated by a first seat device;
drop the received packet by the server when the received packet is not part of the network communication;
drop the received packet by the server when the received packet is a certain type;
drop the received packet by the server when combined bandwidth usage of the plurality of seat devices has reached a first threshold value or when bandwidth usage by the first seat device has reached a second threshold value, wherein the first threshold value and the second threshold value are configurable and stored in a data structure accessible by the server, the first threshold value configured to control bandwidth usage of the aircraft and the second threshold value configured to control bandwidth usage of the first seat device;
generate an egress packet by an application executed by a processor of the first seat device;
drop the egress packet
