Abstract: This application provides a distributed data transmission method, an apparatus, and a system. When sending RTP data to an output device, an input device determines a delay time of a first output device and a delay time of a second output device based on a device delay control list, and sends the RTP data to the first output device and the second output device based on the delay time of the first output device and the delay time of the second output device, so that times for the first output device and the second output device to output the data are the same. The times for the first output device and the second output device to output the data are controlled. Thus, the first output device and the second output device can output the data simultaneously.

Abstract: This application provides a method for generating a pilot signal, including: obtaining, by a terminal device, a correlation identifier and a port number; determining, by the terminal device, a pilot sequence based on the correlation identifier; and generating, by the terminal device, the pilot signal based on the pilot sequence and the port number. The correlation identifier indicates how a pilot sequence is determined and whether the pilot sequence is correlated with a time slot.

Abstract: In a method for implementing data conversion in a cloud data center, a backup server receives a read request from a block storage server. The read request includes a uniform resource locator (URL) address of a to-be-read virtual image object on the backup server and an address range of target data in the to-be-read virtual image object. The backup server obtains an address mapping bitmap and a storage path of backup data in a backup replica corresponding to the to-be-read virtual image object according to the URL address. Thereafter, the backup server obtains the target data from a storage device according to the address range of the target data and the address mapping bitmap and the storage path. Further, the backup server sends the target data to the block storage server. Hence, the conversion time of a backup data object may be shortened.

Abstract: An uplink synchronization method and a terminal are disclosed, where implementation of the terminal is as follows: a supporting terminal sends the reference signal by using a access identifier of a benefited terminal, and receives a adjustment value of synchronization information of the supporting terminal, so that uplink synchronization is implemented. The supporting terminal does not need to access a network, and therefore interference caused by the supporting terminal to another terminal and the benefited terminal on an access device side is avoided, and a preamble signal resource is reduced.

Abstract: A method, an apparatus, and a system for migrating virtual machine backup information, which implement backup information migration after a virtual machine is migrated. The method includes: receiving, by a first backup server, a migration trigger message, where the migration trigger message carries pre-migration virtual-machine identification information and indication information of a second backup server; determining, by the first backup server, backup information of the virtual machine according to the pre-migration virtual-machine identification information; and sending, by the first backup server, the backup information to the second backup server. Therefore, the migrated virtual machine inherits backup information existing before the migration, such that the migrated virtual machine continues to be protected by backup data existing before the migration, and data of the virtual machine is backed up according to a backup policy existing before the migration.
