Abstract: An audio encoding method and apparatus and an audio decoding method and apparatus are disclosed. During encoding of an audio channel signal of a current frame, whether a first target virtual loudspeaker and a second target virtual loudspeaker corresponding to an audio channel signal of a previous frame of the current frame meet a specified condition is first determined. When the first target virtual loudspeaker and the second target virtual loudspeaker meet the specified condition, a first encoding parameter of the audio channel signal of the current frame is determined based on a second encoding parameter of the audio channel signal of the previous frame, so that the audio channel signal of the current frame is encoded based on the first encoding parameter to obtain an encoding result, and the encoding result is written into a bitstream.

Abstract: A packet processing method, a device, and a system are disclosed. In the method, a first provider edge (PE) device receives a first virtual extensible local area network (VXLAN) packet through a first point-to-point (P2P) VXLAN tunnel between the first PE device and a third PE device A customer edge (CE) device is dual-homed to the first PE device and a second PE device respectively through a first Ethernet link and a second Ethernet link. The first PE device forwards the first VXLAN packet to the second PE device through a third P2P VXLAN tunnel from the first PE device to the second PE device when there is a fault on the first Ethernet link. The first Ethernet link connected to the first PE device and a link formed by the third P2P VXLAN tunnel and the second Ethernet link have a primary/secondary relationship.

Abstract: Embodiments of the disclosure relate to a forwarding entry establishment method for a VXLAN. A data center of the VXLAN includes a first layer 3 gateway device, a second layer 3 gateway device, and a first layer 2 gateway device separately connected to the first layer 3 gateway device and the second layer 3 gateway device. The first layer 2 gateway device is connected to a first host. The method includes: establishing, by the first layer 3 gateway device by using an exclusive IP address, an exclusive MAC address, and an exclusive VTEP identifier, a forwarding entry used for communication with the first host. In the embodiments of the disclosure, when one host directly communicates with a plurality of layer 3 gateway devices, a forwarding entry used for communication between the layer 3 gateway devices and the host is correctly established.
