Abstract: This application discloses a placement location obtaining method, a model training method, and a related device. The method includes: obtaining first size information of an unoccupied area in an accommodation space and second size information of a first object; generating M candidate placement locations based on the first size information and N pieces of second size information, where one candidate placement location indicates one placement location of one determined first object in the unoccupied area; generating a first score value of each candidate placement location based on the first size information by using a first machine learning model; and selecting a first placement location from the M candidate placement locations based on the first score value. This avoids excessive dependence on experience of a technical person, and improves an automation level and efficiency of placing/loading an object in the warehousing and/or logistics field.

Abstract: The present invention provides a method and an apparatus for determining video quality, and a method and an apparatus for locating a network fault. The method for determining video quality includes: obtaining a network key performance indicator KPI parameter on a first network device of a plurality of network devices, where the network KPI parameter includes a first round trip time RTT between a head-end device and the first network device; determining a Transmission Control Protocol TCP throughput of the first network device based on the network KPI parameter on the first network device; and determining video quality on the first network device based on the TCP throughput and a played video amount of the first network device. The present invention can accurately determine quality of a video transmitted by using the TCP protocol and accurately locate the network fault.

Abstract: The present invention provides a live video transmission method and system and an apparatus. According to the method, an M2U device receives 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. Then, the M2U device obtains the video data corresponding to the live channel identifier, and obtains 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.
