摘要： The present invention provides a live video transmission method and system and an apparatus. The method includes: receiving, by an M2U device, a UDP request sent by a client, where the UDP request includes a live channel identifier and is used to request video data of a live channel corresponding to the live channel identifier, and the live channel identifier includes a multicast address or a URL; obtaining the video data corresponding to the live channel identifier; and obtaining, by the M2U device, a source IP address and a source port of the UDP request, where the source IP address and the source port of the UDP request are used as a destination IP address and a destination port of a UDP unicast packet to be subsequently sent to the client. After receiving the multicast video data corresponding to the UDP request, the M2U device changes a multicast destination IP address and a multicast destination port into the obtained unicast destination IP address and the unicast destination port of the client, and sends the video data to the client in a UDP unicast manner. The M2U device directly sends the video data in the UDP unicast manner through hardware forwarding without performing protocol conversion on the video data by using a CPU. Therefore, a throughput of the M2U device can be effectively improved.

摘要： This application discloses a network operation, administration, and maintenance OAM method, an apparatus, and a system. The method includes: receiving, by a unified OAM management center, a fault alarm message sent by an MP, where the fault alarm message includes fault information; determining, by the unified OAM management center according to the fault alarm message, a first maintenance set to which the MP belongs, where the first maintenance set includes MPs using a first OAM technology; querying, by the unified OAM management center, an OAM database, to obtain a second maintenance set interacting with the first maintenance set, where the second maintenance set includes MPs using a second OAM technology; and sending, by the unified OAM management center, a fault notification message to all MPs in the second maintenance set or an MP that is determined according to a policy in the second maintenance set. Therefore, a related fault alarm may be centrally notified on a management plane, and is decoupled from a specific OAM technology, thereby greatly reducing an implementation difficulty.

The method includes: obtaining, by a video quality assessment device, a video quality assessment parameter of a to-be-assessed video, where the video quality assessment parameter of the to-be-assessed video includes an average packet loss gap of the to-be-assessed video; determining, by the video quality assessment device, packet loss dispersion of the to-be-assessed video based on the video quality assessment parameter of the to-be-assessed video; and determining, by the video quality assessment device, quality of the to-be-assessed video based on a packet loss rate of the to-be-assessed video, an average consecutive packet loss length of the to-be-assessed video, the packet loss dispersion of the to-be-assessed video, and attribute information of the to-be-assessed video. In the technical solution, during video quality assessment, not only impact of the packet loss rate and an average quantity of consecutively lost packets on the video quality is considered, but also impact of packet loss distribution indicated by the packet loss dispersion on the video quality is considered. Therefore, video quality assessment accuracy can be improved.
