Abstract: An agricultural machine may include a first plurality of sensors configured to measure characteristics of product stored on the machine for use during the machine's operation. The machine may also include a second plurality of sensors configured to measure characteristics associated with operation of the machine, in particular, in the form of feedback from ground engaging mechanisms of the machine, such as row units and wheel assemblies coupled to a frame of the machine. Based on the measured characteristics of the stored product and the measured characteristics associated with the machine's operation, a controller may adjust actuators coupled between adjacent sections of the frame to transfer weight of the stored product between certain sections of the frame, which in turn optimizes the machine's operational characteristics.

Abstract: A system and method are provided for securely routing data through a series of overlay networks without decrypting and encrypting at boundaries between the overlay networks. The packet is routed through first and second overlay networks, and a second overlay network using a header in which the destination-address field encodes both a nexthop destination address and one or more lookup indices that uniquely that are used to look up subsequent nexthop destination addresses. Using a current destination address in the header, the packet is forwarded through the first overlay network to a first router between the overlay networks. A lookup index in the header is used to look up the next destination address (i.e., a transport address across the second overlay network to a second router), which overwrites the current destination address, so that the modified header can be used to forward the packet to the second router.
