    Abstract: A method for determining experience quality of virtual reality (VR) multimedia includes, in a process of playing VR multimedia, obtaining a first sensory parameter, a second sensory parameter, and a third sensory parameter of the VR multimedia, where the first sensory parameter, the second sensory parameter, and the third sensory parameter are obtained by performing sampling separately according to at least two same perceptual dimensions, and are respectively parameters that affect fidelity experience, enjoyment experience, and interaction experience, and determining a mean opinion score (MOS) of the VR multimedia based on the first sensory parameter, the second sensory parameter, and the third sensory parameter of the VR multimedia. Because the third sensory parameter is a parameter that affects the interaction experience, an interaction feature of the VR multimedia is considered.

    Abstract: A method and an apparatus for data traffic restriction are applied to a network device where a link aggregation group interface includes member ports. Firstly, configuring, for each link aggregation group interface, a credit bucket for storing tokens overflowing from a token bucket corresponding to each member port, and the tokens overflowing from the different token buckets are distinctively labeled; receiving a packet to be sent, if a number of tokens in the token bucket is not sufficient for sending the packet to be sent, borrowing, from the credit bucket, tokens overflowing from a non-current token bucket, if the tokens of the current token bucket and the borrowed tokens are sufficient for sending the packet to be sent, sending the packet to be sent, and meanwhile, reducing the number of tokens in the current token bucket and tokens in the credit bucket. A dynamic restriction of data traffic is achieved.

    Abstract: A latch and a D flip-flop, where the latch includes a switch, a resistive random-access memory, a bleeder circuit, and a voltage converter. The voltage converter is configured to output an output signal of the latch according to an input signal of the latch when the switch is in an on state, where the output signal remains consistent with the input signal. When the switch changes from the on state to an off state, the resistive random-access memory is configured to work together with the bleeder circuit to enable an output signal of the latch when the switch is in the off state to remain consistent with an output signal of the latch when the switch is in the on state, thereby implementing a nonvolatile latching function. A circuit structure of the latch is simple and integrity of an existing logic circuit can be improved.

    Abstract: A control method, a control device, and a processor in a software defined network (SDN). In the control method, the control device, and the processor in the SDN provided by the embodiments of the present invention, location information of a network device registered in another control device in the SDN is obtained, so that a remote object proxy of the network device can be established according to the location information, and the network device is controlled using the remote object proxy. Therefore, it is unnecessary to send a control or operation request to device objects of all network devices in other control devices, thereby avoiding a step that the device objects of all the network devices in the other control devices receive a service control request and perform determining, and improving service processing performance.

    Abstract: A method, device, and system for dual-uplink tangent ring convergence, where ports on a network device are classified into conjugate ports and non-conjugate ports. When receiving an entry update packet from a first port or perceiving a state change of a first port, when it is determined that the first port of the network device is a conjugate port, the network device clears a media access control (MAC) entry and an Address Resolution Protocol (ARP) entry that use the first port as an outbound interface and clears all MAC entries that use a non-conjugate port as an outbound interface, in a MAC table and an ARP table of the network device. In this way, traffic interruption can be avoided, wherein a failure of one dual-uplink tangent ring does not cause an entry of one or more other normal dual-uplink tangent rings to be cleared/updated.
