Abstract: A first network device receives an association relationship sent by a second network device, where the association relationship includes an association relationship between a first path and a second path. The first network device generates first routing information between the first network device and a target network device based on the association relationship, where the first routing information is used by the first network device to send a packet to the target network device through the first path, and when a cross-slice condition is met, the first routing information is used by the first network device to send a packet to the target network device through the second path.

Abstract: This application discloses a clock synchronization method and apparatus, and related storage medium, and pertains to the field of communications technologies. A network device receives an announce message from a first master clock node and an announce message from a second master clock node; and when an identifier of a first clock source node carried in the announce message of the first master clock node is the same as an identifier of a second clock source node carried in the announce message of the second master clock node, selects a master clock node with a smaller clock deviation from the first master clock node and the second master clock node, and then calibrates a clock of the network device based on time information of the master clock node. The precision of clock synchronization by the network device is improved.

Abstract: A memory management method includes: obtaining a resource requirement that a process in kernel space awaits; when detected that a first process is in a first state and meets a preset condition, changing the first process in the first state to a second state, and swapping out a memory resource of the first process; and when detected that a released system resource meets a resource requirement of the first process in the second state, changing a status of the first process, and swapping in a memory resource.

Abstract: This application discloses a clock synchronization method and apparatus, and a storage medium, which pertains to the field of communication technologies. The method includes: first receiving, by a network device, an announce packet from a first master clock node and an announce packet from a second master clock node, when an identifier of a first clock source node carried in the announce packet from the first master clock node is the same as an identifier of a second clock source node carried in the announce packet from the second master clock node, selecting a master clock node with a relatively small clock deviation, and then calibrating a clock of the network device based on time information of the master clock node. In this application, precision of clock synchronization performed by the network device is higher, and further, precision of a clock calibrated by the network device is higher.

Abstract: A time synchronization method includes receiving, by a receive-end device, a first timestamp and a first header signal sent by a transmit-end device, where the first timestamp indicates a first moment at which a first channel medium conversion module sends the first header signal, and a second moment at which the receive-end device receives the first header signal. The method further includes sending a second header signal to the transmit-end device, where a third moment at which the receive-end device sends the second header signal. The method further includes receiving a fourth timestamp sent by the transmit-end device, where the fourth timestamp indicates a fourth moment at which the transmit-end device receives the second header signal. The method further includes synchronizing time with the transmit-end device based on the first moment, the second moment, the third moment, and the fourth moment.
