摘要： A micro fluid control apparatus (100) and an electronic device (1) are provided. The micro fluid control apparatus (100) includes an oscillator layer (20) and a resonance layer (10) that are stacked. A vibration portion (21) of the oscillator layer (20) is connected to a fastening portion (22) by using a connection portion (23). The vibration portion (21) can vibrate. The micro fluid control apparatus (100) further includes a bonding layer (30) and a support structure (12). The bonding layer (30) is located between the fastening portion (22) and the resonance layer (10), so that the resonance layer (10) is connected to the oscillator layer (20) by using the bonding layer (30). The support structure (12) is also located between the fastening portion (22) and the resonance layer (10), so that a spacing is reserved between the resonance layer (10) and the oscillator layer (20). In this way, the support structure (12), the oscillator layer (20), and the resonance layer (10) form, in an enclosing manner, a chamber for accommodating fluid and allowing the fluid to pass through, to control a flow of the fluid. The spacing is formed between the oscillator layer and the resonance layer by using a support height of the support structure, and a height and a position of the support structure are easy to control, so that a height of the spacing is accurately controlled. This reduces or avoids an excessively large or excessively small height of the spacing, ensures consistency of the height of the spacing, and improves performance of the micro fluid control apparatus.

摘要： This application provides an information synchronization method. The method includes: sending, by a controller, a first message to a network device, where the first message carries CRP routing entry information, and is used to advertise a CRP route, and the first message includes first identification information; and after receiving the first message, storing, by a forwarding device, the CRP routing entry information into a CRP routing table of the network device as indicated by the first identification information. In the technical solutions of this application, because a route advertised by the controller and a route advertised by using a routing protocol between forwarding devices are stored in different routing tables, a related application of the route advertised by using the routing protocol between the forwarding devices is not affected.

摘要： An information management method is provided. A controller generates a first message carrying an address of a first next hop of a network device. The first message includes first identification information. The first identification information is used to instruct the network device to delete, from a next hop table stored in the network device, an entry that is of the first next hop and that corresponds to the address of the first next hop. The network device receives the first message, and deletes the entry of the first next hop as indicated by the first identification information. The controller can withdraw an unavailable next hop by separately sending information about the next hop to the network device without route prefix information, effectively saving a system resource occupied for route withdrawal message exchanging between the controller and the network device, and improving service processing efficiency.

摘要： Embodiments of the present invention disclose a path determining method, apparatus, and system. In a hybrid network including one controller for implementing a control function, the controller may separately obtain network topology information of a first network and a second network of different network types by using a same control channel protocol. When the controller obtains a path determining requirement for the data transmission path, because the controller has the network topology information of the first network and the second network, during computation of the data transmission path, the controller can determine a path computation result including transmission path parts of the first network and the second network, without performing additional information exchange with another device, and send the path computation result to the first network device. In this way, planning efficiency of the data transmission path is improved.
