Abstract: Provided are an interaction method and apparatus in a live streaming room, a device, and a storage medium. The method comprises: in response to a trigger operation for a preset drawing entry on a live streaming room page, jumping to a graphic drawing page from the live streaming room page, a drawing trajectory set for a preset object being displayed on the graphical drawing page; when a drawing stroke on the graphic drawing page is received, matching the drawing stroke with the drawing trajectory; and if it is determined that the drawing stroke is successfully matched with the drawing trajectory, displaying prompt information about successful participation in a preset activity, the preset activity and the preset drawing entry having a correspondence.

Abstract: A method and device for forwarding a packet are disclosed. When a first access device connected with a database server is to be configured with a mirror image rule, an SDN controller can transmit a mirror image rule adding message carrying the mirror image rule to the first access device. Where, the mirror image rule comprises an IP address of the database server, a MAC address of a database audit device connected with a second access device and a VXLAN tunnel between the first access device and the second access device. When receiving a database access packet whose destination IP address is an IP address of the database server, the first access device may replace a destination MAC address of a mirror packet for the database access packet with a MAC address of the database audit device according to the mirror image rule and forward the encapsulated VXLAN packet.

Abstract: According to an example, in a spinlock processing method, a value of a spinlock cache variable may be read from a cache and the value of the spinlock cache variable may be written into a register. A determination may be made as to whether the value of the spinlock cache variable is an initial value. If yes, the value of the spinlock cache variable in the register may be updated. A determination may also be made as to whether the spinlock cache variable is accessed by a core after the value of the spinlock cache variable is written into the register. If yes, a value of a spinlock cache variable may be obtained from the cache. If no, the updated value of the spinlock cache variable may be written into the cache. Moreover, an access speed of the cache may be larger than an access speed of an L2 cache.

Abstract: A method accelerates access of a multi-core system to its critical resources, which includes preparing to delete a critical node in a critical resource, separating the critical node from the critical resource, and deleting the critical node if the conditions for deleting the critical node are satisfied. An apparatus includes a confirmation module for the node to be deleted and a deletion module to accelerate access of a multi-core system to its critical resources.
