Abstract: A packet forwarding method, a device, and a system, where a first provider edge (PE) device separately sends request packets to a second PE device and a third PE device. The second PE device receives the two request packets separately using a primary pseudo wire (PW) and using a secondary PW, the third PE device, and a bypass PW, switches preferential forwarding statuses relative to the primary PW and the bypass PW to a balance state, and then, notifies the first PE device and the third PE device using a response packet. The first PE device switches preferential forwarding statuses relative to the primary PW and the secondary PW to the balance state based on the response packet. The third PE device switches a preferential forwarding status relative to the bypass PW to the balance state based on the response packet.

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: An information backup method applied to a communications system including a primary device, a secondary device, and a cloud device, and the method is performed by the primary device. The method includes sending a first identity notification to the cloud device, where the first identity notification is a notification indicating that the primary device has a primary device identity, and uploading obtained first user information to the cloud device when determining that a communication status of the cloud device is normal, where the first user information is stored by the cloud device and provided to the secondary device, and the first user information is to-be-backed-up information of user equipment that gets online from the primary device when the communication status of the cloud device is normal.

Abstract: This application provides a file download method, a device, and a system, and belongs to the field of network technologies. In this application, in a three-layer system architecture including a client device, a relay device, and a server device, indication information is added to a packet, to indicate that the relay device has a file required by the client. The client device can download the file from the relay device by interacting with the relay device, so that the client device can download the file nearby. This reduces bandwidth occupied for file transfer.

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.
