Abstract: The method in the embodiments of the present invention includes after a service management system SMS detects that operating performance data of a VNF is abnormal, sending network service association request information to a system management module, where the network service association request information is used by the system management module to query a fault and feed back a network service association response to the SMS. The method also includes performing, by the SMS, fault diagnosis according to the network service fault association response and the operating performance data of the VNF, to obtain a network service fault diagnosis report. Additionally, the method includes sending the network service fault diagnosis report to the system management module, where the network service fault diagnosis report is used by the system management module to perform fault recovery.

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.
