A method and system are described for permitting a dumb device having no operating system to create and transmit a network packet utilizing a network. The dumb device is coupled to a client computer system utilizing the network. A network interface is established within the dumb device. In response to an event, the dumb device generates an internal output signal. The output signal is received within the dumb device by the network interface. In response to a receipt of the output signal, the network interface creates and transmits a network packet including an indication of the event to the client computer system, wherein a dumb device having no operating system creates and transmits a network packet.

A method according to claim 1, comprising the steps of: a) generating in the input port interface in response to detection that the data frame belongs to a known data flow a unique switch header including a source identification field, a destination identification field defining an output trunk interface as the destination of the data frame, and a forwarding label, the unique switch header being concatenated to the data frame, b) sending the data frame with the concatenated unique switch header to the output trunk interface defined in the destination identification field of the unique switch header via the switch engine, and, c) transmitting the data frame from the output trunk interface over the network with the forwarding label. 3. A method according to claim 2, wherein the unique switch header concatenated to the data frame is composed by using the contents of the input table which have been updated by the update message and wherein the switching label is used as forwarding label. 4. A method according to claim 1, wherein the identification field of the first switch header defines the router as the destination for the data frame when this one does not belong to a known flow of data. 5. A method according to claim 1 wherein the destination identification for the second switch header defines the output trunk interface which is mapped to a virtual circuit between the router and the router interface. 6. A method comprising the steps of: a) identifying as a routing label assigned by an output trunk interface of a node a label concatenated with an Internet Protocol (IP) data frame being transmitted between a sending unit connected to an ingress switching node and a receiving unit connected to an egress switching node, the ingress switching node being linked to the egress switching node by a plurality of intermediate switching nodes interconnected by trunks, and each of the ingress switching node, egress switching node and intermediate switching nodes including a switch engine in charge of switching any data frame from an input port/trunk interfacing the switch engine by an input port/trunk interface to an output trunk/port interfacing the switch engine by an output trunk/port interface and a router interfacing the switch engine by a router interface in charge of routing each flow of data from the ingress switching node to the egress switching node when the first data frame of the flow of data is received by the intermediate switching node b) generating, in the input port interface of the intermediate switching node, a first switch header including a source identification field, a destination identification field and a temporary label identifying the flow of data in response to the first data frame, the first switch header being concatenated to the data frame, c) transmitting the data frame with the concatenated first switch header to the router interface via the switch engine when the data frame does not belong to a known flow of data, d) storing the source identification and default label contained in the first switch header in a buffer of the router interface before transmitting the data frame to the router for de
