Abstract: A video service quality assessment method and apparatus are provided to resolve a prior-art problem of relatively low accuracy of an assessment result. A monitoring device obtains an identifier of a to-be-monitored channel, an identifier of to-be-monitored user equipment, and configuration information of a video service transmission system; obtains a multicast video stream of the to-be-monitored channel based on the identifier of the to-be-monitored channel; obtains a retransmitted video stream based on the identifier of the to-be-monitored channel, the identifier of the to-be-monitored user equipment, and the configuration information of the video service transmission system; determines a to-be-assessed video stream based on the multicast video stream and the retransmitted video stream; and parses the to-be-assessed video stream, and obtains an assessment result based on a parsing result and the configuration information of the video service transmission system.

Abstract: This application provides a data transmission method and a apparatus. The method includes: when determining that a first data stream satisfies a transmission optimization enabling condition, a first transmitting end TE1 sends a transmission optimization enabling notification to a first receiving end RE1, where the transmission optimization enabling notification is used to indicate the RE1 to skip sending, to the TE1, an acknowledgment packet used to acknowledge that a data packet of the first data stream is already received by the RE2. The TE1 receives a data packet Data2 in a second protocol format from the TE2. The TE1 sends a data packet Data1 in a first protocol format to the RE1. The TE1 receives an acknowledgment frame Ack1 in the first protocol format from the RE1. The TE1 constructs an acknowledgment packet Ack2 in the second protocol format based on the Ack1, and sends it to the TE2.
