The invention provides a table entry generation method and device, and the method comprises the steps: forwarding a data message transmitted by opposite-end network equipment to a first host through an aggregation port when the data message is received through a first tunnel; adding a forwarding table entry in a forwarding table of a first distributed gateway, the destination address of the forwarding table entry being the address of a second host, and the egress port of the forwarding table entry being the tunnel identifier of the first tunnel; and sending a table entry synchronization message to a second distributed gateway, the table entry synchronization message comprising the address of the second host and the tunnel information of the first tunnel, so that the second distributed gateway adds the forwarding table entry to a forwarding table of the second distributed gateway according to the table entry synchronization message. According to the technical scheme of the embodiment ofthe invention, after the first distributed gateway or the second distributed gateway receives the data message through the aggregation port, the data message is sent based on the forwarding table entry, so that the data message is correctly forwarded.

The invention provides a preparation method of a micro-electromechanical system magnetic core solenoid micro-inductance device. Using the micro-electromechanical system MEMS technology, the double-sided oxidized silicon wafer is processed to obtain double-sided overlay alignment symbols, so as to improve exposure during exposure. Alignment accuracy, use physical etching technology to remove the seed layer, and use one-time electroplating to connect the conductor. The prepared micro-inductance device is mainly composed of substrate, pin, coil, and magnetic core. Two groups of ring-shaped closed magnetic cores are symmetrically wound The connected three-dimensional solenoid coil is formed by connecting the bottom coil and the top coil through a connecting conductor, and the bottom coil, the top coil and the connecting conductor are separated by a polyimide insulating material and a magnetic core. The method of the invention avoids the undercutting phenomenon caused by the wet etching process, solves the three-dimensional winding of the coil and the insulation problem between layers and the electroplating problem of high aspect ratio, and greatly improves the inductance performance of the micro-inductance device.
