Abstract: This application relates to the field of communication technologies, and discloses a method and an apparatus for determining a link for forwarding a service flow, and a storage medium. A first forwarding device obtains identification information of a first service flow; and determines, based on the identification information of the first service flow, a link bandwidth matrix, and link statuses respectively corresponding to N links, a first link for forwarding the first service flow. A hash operation does not need to be performed based on a device identifier of each forwarding device, and a specific forwarding device that performs forwarding does not need to be determined by comparing a plurality of hash values.

Abstract: This application provides a control plane device switching method. When a user plane device in the forwarding-control separation system detects that performance of communication between the user plane device and an active control plane device does not meet a normal communication condition, and performance of communication between the user plane device and a standby control plane device meets the normal communication condition, the user plane device may send a switching request to the standby control plane device. When detecting that a quantity of user plane devices that each send the switching request is greater than or equal to a first quantity threshold, the standby control plane device may indicate each user plane device in the forwarding-control separation system to switch to the standby control plane device, so that the standby control plane device can replace the active control plane device to work, thereby ensuring normal running of a user service.

Abstract: A control plane (CP) device switching method includes that when a user plane (UP) device in a forwarding-control separation system detects that performance of communication between the UP device and an active CP device does not meet a normal communication condition, and performance of communication between the UP device and a standby CP device meets the normal communication condition, the UP device sends a switching request to the standby CP device. When detecting that a quantity of UP devices that each send the switching request is greater than or equal to a first quantity threshold, the standby CP device may indicate each UP device in the forwarding-control separation system to switch to the standby CP device.

Abstract: A network system includes a first network device, a second network device, and a third network device. The first network device is configured to: obtain a first route advertisement message, where the first route advertisement message includes a first route prefix; and obtain a second route prefix based on the first route prefix, where the second route prefix corresponds to a first network slice, and the second route prefix is a subnet prefix of the first route prefix. The first network device advertises a second route advertisement message to the second network device, where the second route advertisement message includes the second route prefix.
