Abstract: A packet forwarding method and apparatus are described that pertain to the field of communication technologies. During selecting, from outbound interfaces of a plurality of forwarding chips, an outbound interface used for packet forwarding, a chassis-shaped device considers both: a role of the outbound interface (whether the outbound interface is an outbound interface of a shortest path or an outbound interface of a non-shortest path), and a congested state of the outbound interface. As such, the chassis-shaped device flexibly selects a forwarding path for a data packet based on a congestion situation of the forwarding path. In this way, an application of an adaptive routing technology is extended to the chassis-shaped device.

Abstract: Provided are a method for controlling a virtual object to pick virtual props performed by a terminal. The method includes: displaying a prop picking list, the prop picking list comprising prop picking controls of virtual props; receiving an operation on a first prop picking control in the prop picking list; determining a picking mode associated with the operation on the first prop picking control, the picking mode of the first virtual prop comprising (i) picking and using or (ii) picking and carrying; and controlling the virtual object to pick a first virtual prop based on the picking mode associated with the operation. The method can simplify picking operations on virtual props and improve prop picking efficiency.

Abstract: Disclosed are a card casting method performed by a terminal device, belonging to the fields of Internet and computer technologies. The method includes: displaying a game application interface, the game application interface including a first card and a plurality of candidate positions corresponding to the first card; displaying a position selection control in response to a first operation on the first card, the position selection control including a plurality of trigger regions, each trigger region corresponding to a respective one of the plurality of candidate positions; determining a target position from the plurality of candidate positions in response to a second operation on a corresponding target trigger region of the position selection control; and casting the first card to the target position. The method simplifies the process of casting the first card to the target position in a game application and reducing operation difficulty in casting the first card.

Abstract: A method includes displaying a virtual map of a virtual environment including an identification of a first virtual object and an identification of a second virtual object in the virtual environment, and displaying a hot zone display element on the virtual map in response to a determination that the first virtual object interacts with the second virtual object. The hot zone display element indicates a map area in which the first virtual object interacts with the second virtual object. The method further includes displaying a visual field picture of the virtual environment from a perspective of the first virtual object or the second virtual object in response to a trigger operation on the hot zone display element.

Abstract: A method for controlling an antenna of a mobile communication application system based on double quaternions in MEMS inertial navigation. The method comprises: introducing an antenna control quaternion based on a navigation attitude quaternion; in each interrupt cycle of a navigation computer, updating the two quaternions respectively using a carrier system measured by a gyroscope relative to a rotation vector of an ideal platform coordinate system; in each filter cycle, correcting the error of the navigation attitude quaternion respectively using a Kalman filter; according to the relationship between the attitudes determined by the two attitude quaternions, determining the angular speed in an antenna control instruction; and finally, driving a servo system to rotate at an antenna servo control angle converted by an antenna control quaternion attitude.

Abstract: A packet forwarding method and system. A first network device encapsulates a to-be-forwarded packet as a first packet, and sends the first packet to a second network device, where the first packet carries a destination Media Access Control (MAC) address encapsulation instruction, the destination MAC address encapsulation instruction is used to instruct the second network device to encapsulate a destination MAC address for the first packet, the to-be-forwarded packet carries a destination internet protocol (IP) address, and the destination MAC address is a MAC address of a destination host corresponding to the destination IP address; the second network device generates a second packet containing the destination MAC address according to the destination MAC address encapsulation instruction carried by the received first packet, and forwards the second packet to the destination host corresponding to the destination MAC address.
