Abstract: An identifier can indicate whether local protection is allowed is added to a packet. In a process in which a packet that carries a protection flag is transmitted along a primary path, if a node along the path determines that the primary path is faulty, but the protection flag indicates that local switching to a protection path is not allowed, the node along the path does not perform local protection, so that the packet is not switched by the node along the path to the protection path. This prevents the packet from passing through a protection path with the node along the path as an ingress when the primary path is faulty, helps traffic on the primary path to be switched to an end-to-end protection path in time, and helps a packet sending side to switch the traffic on the primary path to the end-to-end protection path in time.

Abstract: Method, system, medium, and implementation for robot-guided instrument insertion. A preplanned path between a three-dimensional (3D) entry pose on skin of a patient to a 3D pose of a target is generated for a surgery with a target inside the patient. The preplanned path is used by a robot as guidance to insert a surgical instrument from the 3D entry pose to reach the 3D pose of the target. During the surgery, a next pose is determined based on a current pose of the surgical instrument and the preplanned path as well as spatial relationship to surrounding anatomical structures and is used to move the surgical instrument thereto. An updated current pose of the instrument is then obtained via tracking when the robot is advancing the surgical instrument to the next pose. The process repeats until the instrument reaches the target pose.
