摘要： A method for determining a processing capability includes: a first node sends a message to a second node. The message includes extension header processing capability information, and the extension header processing capability information is used to indicate a processing capability of the first node for an Internet Protocol (IP) version 6 (IPv6) extension header. After receiving the message, the second node obtains, based on the extension header processing capability information, the processing capability of the first node for the IPv6 extension header to determine whether the first node needs to forward or receive a packet.

摘要： A method for collecting bit error information is provided. According to the method, a head node may encapsulate indication information into an IPv6 extension header of an IPv6 measurement request packet. The indication information indicates at least one intermediate node on a transmission path of the IPv6 measurement request packet to record bit error information into the IPv6 extension header. According to the application, the bit error information of the intermediate node on the transmission path can be collected.

摘要： A packet processing method includes carrying an associated channel in an IPv6 packet to provide different types of control channels. The associated channel may be transmitted together with user data. Each type of control channel carries at least one type of control and management message, and one type of control and management message may implement one type of control and management function. For example, if a plurality of control and management functions need to be implemented for the IPv6 network, a plurality of different types of control and management messages may all be carried by using the associated channel, without using a plurality of protocols to carry the plurality of types of control and management messages.

摘要： A method and an apparatus for implementing model training, and a computer storage medium are disclosed, and belong to the field of machine learning. When a machine learning model deteriorates, an analysis device first obtains validity information of a first feature set, where the first feature set includes a plurality of features used for training to obtain the machine learning model, the validity information includes a validity score of each feature in the first feature set, and a validity score of a feature is negatively related to correlation of the feature with another feature in the first feature set. Then an invalid feature in the first feature set is determined based on the validity information. A second feature set that does not include the invalid feature is finally generated, where the second feature set is used to retrain the machine learning model.

摘要： A cell site gateway (CSG) determining method includes a first device obtains, before a first moment, a location range in which a mobile device is located at the first moment; and the first device obtains an identifier of at least one target CSG based on the location range before the first moment, where the at least one target CSG can provide downlink data transmission for the mobile device at the first moment. The target CSG that can provide the downlink data transmission for the mobile device at the first moment is further determined through estimation of the location range in which the mobile device is located at a subsequent first moment.
