    Abstract: A first data center interconnection (DCI) device in a first data center receives a first packet from a Border Gateway Protocol Ethernet virtual private network (BGP EVPN) neighbor, where the first packet includes routing information of a first forwarding instance of an access device in the first data center and an export route target of the first forwarding instance. The first DCI device obtains a second forwarding instance that corresponds to the first packet, where an import route target of the second forwarding instance matches the export route target of the first forwarding instance. The first DCI device generates a second packet that includes routing information of the second forwarding instance and an export route target of the second forwarding instance, which includes a DCI interworking route target. The first DCI device sends the second packet to a second DCI device in a second data center.

    Abstract: This application provides a data traffic processing method, a device, and a system. The method includes: receiving, by a first network device on a first link, a first VXLAN packet sent by a second network device, where the first VXLAN packet includes a first sequence number and a first service packet; decapsulating, by the first network device, the first VXLAN packet; receiving, by the first network device on a second link, a second VXLAN packet sent by the second network device, where the second VXLAN packet includes a second sequence number and a second service packet; and when the first network device determines that the second sequence number is a next sequence number of the first sequence number, decapsulating, by the first network device, the second VXLAN packet.

    Abstract: A stereo encoding method includes: performing downmix processing on a left channel signal of a current frame and a right channel signal of the current frame to obtain a primary channel signal of the current frame and a secondary channel signal of the current frame; and when determining to perform differential encoding on a pitch period of the secondary channel signal, performing differential encoding on the pitch period of the secondary channel signal using an estimated pitch period value of the primary channel signal to obtain a pitch period index value of the secondary channel signal, where the pitch period index value of the secondary channel signal is used to generate a to-be-sent stereo encoded bitstream.

    Abstract: This application provides a VXLAN packet processing method, a device, and a system. After determining that a data packet sent by a CE device is a BUM packet, a PE device encapsulates the BUM packet to generate a VXLAN packet including an ESI label and a VXLAN packet including a BUM traffic label. The VXLAN packet including the ESI label is sent to an active-active gateway, so that the gateway can block forwarding of traffic to the CE device by using an interface configured with an ESI, to avoid a loop between the PE device and the CE device. The VXLAN packet including the BUM traffic label is sent to a remote PE, to block forwarding of the VXLAN packet to the CE device by using a secondary DF interface, thereby avoiding a multi-packet problem.

    Abstract: Embodiments of the present disclosure provide a resource allocation method, a network-side device, and a terminal device. The resource allocation method includes: allocating, by a network-side device, a first resource, where the first resource is used to carry a positioning reference signal, and the positioning reference signal is used to perform positioning on a terminal device; determining, by the network-side device, a first allocation mode of the first resource, where the first allocation mode is configuring the positioning reference signal in all unoccupied locations of the first resource; and sending, by the network-side device, the positioning reference signal on the first resource in the first allocation mode, or receiving, by the network-side device, the positioning reference signal on the first resource in the first allocation mode.
