First Claim
1. A method for providing network connections aboard a vehicle, comprising:
- at a first device aboard a first vehicle providing a first virtual network to which at least one second device can connect;
entering a first operational mode in which data transmitted by said at least one second device over said first virtual network is received by said first device;
detecting a presence of a third device aboard a second vehicle, said third device being adapted to also provide said first virtual network to which said at least one second device can connect; and
entering a second operational mode in which data transmitted to said first virtual network is not received by said first device;
wherein said first device and said third device are each further arranged to provide a second virtual network to which said at least one second device can connect; and
wherein in each of said first and second operational modes of said first device is arranged to receive data transmitted by said at least one second device over said second virtual network.

Abstract
A method of transmitting data from a first device. The method comprises: at the first device, establishing a connection with a first one of a plurality of second devices and establishing a first virtual connection, the first virtual connection being between the first device and a third device through the first one of a plurality of second devices; and receiving details of a second virtual connection, the second virtual connection being between a fourth device and the third device through a second one of the plurality of second devices, the fourth device being connected to the first device. The method further comprises selecting one of said first or second virtual connections for transmission of a data packet to said third device and transmitting data to said third device using said selected connection.
