The invention discloses a method for achieving the consistency of message forwarding paths. The method comprises the steps that: if network equipment receives a message through a port which enables paths to be unified, a binding record is carried out on a hash calculation result obtained after the element information of the message is subjected to hash calculation and the port number of the port for receiving the message; if a message which is the same as the hash calculating result is received through the port which cannot enable the path to be unified, the message can be forwarded based on the binding record. On the basis of the same inventive concept, the invention also provides network equipment which can conveniently and flexibly achieve the consistency of the paths during forwarding the message and the capacity expansion of the network is not influenced.

The invention relates to a binary intelligent structure control device and method of satellite flexible vibration. The control device comprises a plurality of piezoelectric sensors, a plurality of SMA (Shape Memory Alloy) wires and a controller, wherein the plurality of piezoelectric sensors transmit a voltage sensed through a cable to the controller which converts the voltage into a control current of the SMA wires, the control current is transmitted to the plurality of piezoelectric sensors through the cable, and the SMA wires are controlled to generate tension to control satellite flexiblevibration.
