Patent ID: 7123614

Claim:
A method of data packet transmission from a first network to a second network via a communication device interconnecting the first and second networks, one of the first and second networks being a communication bus transporting data packets in isochronous and asynchronous modes, the other one of the first and second networks being a packet-switching network transporting data packets in connected and non-connected modes, the method comprising the steps of: receiving data packets from the first network in a reception memory of the communication device; reserving a storage area internal to the communication device, wherein the reserved internal storage area is adapted to the mode in which data packets are received from the first network; storing the received data packets in the reserved internal storage area of the communication device; and transmitting data packets to the second network through the reserved internal storage area, in a mode associated with the receiving mode; wherein in a case in which the isochronous mode is associated with the connected mode, the reserving step is performed before the communication device receives data packets from the first network, and in a case in which the asynchronous mode is associated with the non-connected mode, the reserving step is performed after the communication device receives data packets from the first network.
