Abstract: A BGP message sending method includes: determining, by a first network device, that a host identified by a first MAC address is an attacker; generating, by the first network device, a BGP message, where the BGP message includes the first MAC address and indication information, and the indication information is used to indicate that the host identified by the first MAC address is the attacker; and sending, by the first network device, the BGP message to a second network device.

Abstract: A robot state planning method based on a Monte Carlo tree search algorithm. The method comprises: obtaining an initial state and a target state of a robot (step 100); by using the initial state as a starting node, using a Monte Carlo tree search algorithm to expand a Monte Carlo tree until a generated target node reaches the target state (step 200); and determining a state sequence of the robot according to all nodes from the starting node to the target node (step 300). According to the solution, the overall state in the motion process is planned, and a state sequence is generated; thus, effect of front back coupling caused by planning according to periods can be avoided, and the passing capability of a six-foot robot in a complex terrain is improved.

Abstract: A soft biomimetic legged robot is provided in the present invention, including a plurality of soft robotic arms. The soft robotic arms include a plurality of motion units, and each of the motion units includes one or more of a twist module, an extension module, a contraction, and a bending module. The plurality of motion units is combined to achieve a full-posture motion of the soft robotic arms. By using soft robotic arms composed of different motion units, the soft biomimetic legged robot of the present invention can not only realize the underwater swimming and crawling, but the crawling on land or slopes, thereby adapting to more complicated environments and achieving richer functions. The motion posture is not limited to a single bending, twisting, extension, and shortening. The soft robotic arm can achieve full-posture movements, and its motion type is more complete.
