Method for rapidly flashing sensor nodes via an ethernet network

A method for rapidly flashing sensor nodes via an Ethernet network having a head node and a plurality of associated nodes, wherein the method comprises:

• a) determining the number of active nodes by a head node;
• b) classifying the identified nodes in two or more classifications of node to prioritize the Ethernet network communication by the head node;
• c) receiving reservation requests from at least some of the plurality of nodes by the head node;
• and
• d) assigning to one or more nodes in the upcoming communication window time slots in response to reservation requests, wherein the assignments are based on a node priority and the priority is assigned to the nodes in accordance with their classification,
• wherein, after the number of active nodes has been determined, a necessary download data rate is determined and a current bus utilization is ascertained, wherein the bus utilization is ascertained by calculating the time difference of a final beacon and the number of nodes, and the bus cycle of the Ethernet network is optimized in terms of the necessary download data rate.
