Abstract: A data multicast implementation method, apparatus, and system are provided. In some embodiments, a transmission device receives a standby forwarding path establishment request, where the standby forwarding path establishment request includes a device identifier, has a destination address being an address of a multicast source device, and is used to request to establish a standby forwarding path between a multicast destination device identified by the device identifier and the multicast source device. In those embodiments, when determining, based on the device identifier in the standby forwarding path establishment request, that the transmission device is located on an active forwarding path between the multicast destination device and the multicast source device, the transmission device skips using the transmission device as a device on the standby forwarding path between the multicast destination device and the multicast source device, and skips forwarding the standby forwarding path establishment request.

Abstract: A TOE component obtains a first storage address, where the first storage address is an address of a first storage block in a memory, the first storage block stores a target TCP packet, and the target TCP packet includes a packet header and a TCP payload. The TOE component obtains the packet header from the first storage block based on the first storage address. The TOE component performs TCP-related protocol processing based on the packet header, where the TCP payload is not read out of the first storage block by the TOE component when the TOE component performs TCP-related protocol processing based on the packet header.

Abstract: A method for implementing fault detection includes: instructing, by a detection device, a detected device to configure a detected path and a return path, where the detected path is a path from a first physical port of the detected device to a second physical port of the detected device via a target unit of the detected device, the return path is a path from the second physical port to the detection device, and the target unit is a VNF or an accelerator; sending a detection packet to the detected device through the first physical port; and when receiving the detection packet transmitted through the detected path and the return path, determining that the detected path is not faulty. According to the method, it can be further determined that the path that passes through the VNF or the accelerator is not faulty.

Abstract: A virtual machine live migration method, apparatus, and system relating to the field of communications technologies are disclosed. The method includes: in a process of live migration of a target virtual machine, obtaining pre-recorded storage location information corresponding to target service configuration information, where the target service configuration information is used by a target virtual acceleration component corresponding to the target virtual machine to perform service processing; reading the target service configuration information in a storage location corresponding to the storage location information; and sending the target service configuration information to a destination server, so that the destination server stores the target service configuration information. In the present disclosure, a service processing failure can be avoided.
