Claim Text:
1. A method for providing an external optical data packet to a destination node of a packet optical network, the packet optical network comprising a plurality of nodes and a first optical data channel for optically communicating local optical data packets between the plurality of nodes, the method comprising: optically converting the external optical data packet for a transmission to the destination node over a second optical data channel of the packet optical network, the first and second optical data channels being independent of each other; optically transferring the converted external optical data packet to the packet optical network; and transmitting the converted external optical data packet to the destination node over the second optical data channel, wherein the external optical data packet comprises a header and a payload section, and wherein the header comprises control information and the payload section comprises data payload, wherein the method comprises upon receipt of the external optical data packet sending a notification to the packet optical network, the notification comprising address information about the destination node, wherein the packet optical network further comprises a control channel for communicating control channel information between the plurality of nodes, and wherein the method comprises: preparing the control header for the external optical data packet on the basis of the received notification, and transmitting the control header over the control channel upon transmitting the converted external optical data packet over the second data channel.
