in step S103, the target migration object data and the address information of the migration source are sent to a migration destination, so that the target migration object takes the address information of the migration source as the source address information of the target migration object when sending a message at the migration destination.

As mentioned above, with the development of scientific technology and data technology, the application of cloud service technology is becoming more and more widespread. Cloud service providers usually operate massive software and hardware infrastructures, and as online and offline maintenance of equipment, scheduling of resources, and moving of stocks and the like occur more and more frequently, how to reduce data interruption or response time as much as possible during operation and maintenance operations to enable data to be transferred smoothly and reduce the influence of data transfer on users as much as possible, even achieve the imperceptibility of users is a crucial problem for cloud service providers. In the prior art, data migration is usually performed by adopting a hot migration technology, which is effective for most of data to be migrated and basically can achieve user imperceptibility, but generally does not meet the requirement of seamless migration for objects such as processes to be migrated, programs and the like which depend on connection states and source address information.

In view of the above, in this embodiment, a data processing method is proposed that transmits target migration target data to be migrated to a migration destination together with address information of a migration source. The technical scheme can not only ensure that most of data to be migrated is insensitive to users under the condition of effective migration, but also meet the requirement of seamless migration of users for objects such as processes to be migrated, programs and the like which depend on connection states and source address information, so that the data service quality can be effectively improved.

In an embodiment of the present disclosure, the data processing method is applied to a physical machine, a physical machine loaded with a virtual machine, or a migration source device running one or more processes or programs and capable of performing migration.

In an embodiment of the present disclosure, the data migration command refers to a command for initiating data migration, where the data migration command may be issued by an external controller, may be issued by a device where data to be migrated is located, may be issued by a device that receives the data to be migrated, and may also be issued by another device, and the present disclosure does not specifically limit the departure of the data migration command.

In an embodiment of the present disclosure, the migration source refers to a device where data to be migrated is located, and the migration destination refers to a destination device where the data to be migrated is migrated, for example, if a data migration task needs to migrate a virtual machine from a physical machine a to a physical machine B, the physical machine a is the migration source, and the physical machine B is the migration destination.

In an embodiment of the present disclosure, the target migration object refers to an object such as a process or a program that needs to be migrated, depends on a connection state, and depends on source address information.

In an embodiment of the present disclosure, the address information of the migration source refers to information for identifying a location of the migration source, for example, if the migration source is a physical machine a, the address information of the migration source may be an IP address of the physical machine a.

In an embodiment of the present disclosure, the target migration object data may be obtained by accessing a log file of the target migration object, and the like.

In an embodiment of the present disclosure, after the step S101, that is, after acquiring the target migration object data of the migration source in response to receiving the data migration command, the method may further include:

The data switching device refers to a device for switching or routing data, such as a switch, and in the virtualization technology, may also be a virtual switch.

In an embodiment of the present disclosure, the target migration object file refers to a file for storing the target migration object data, and the target migration object file may be a file newly created for a certain target migration object in response to the data migration command, or a file created in a history, as long as the file can store the target migration object data and uniquely identify the storage content, so as to distinguish and determine the target migration object data and the storage location thereof.

In order to generate a target migration object file capable of storing target migration object data to facilitate migration of data, in this embodiment, the target migration object data of the migration source is stored into the target migration object file by calling an interface of the data exchange device.

In an embodiment of the present disclosure, the step S103, that is, the step of sending the target migration target data and the address information of the migration source to the migration destination, may be implemented as:

In this embodiment, in order to enable the target migration object to use the address information of the migration source as the source address information of the target migration object when sending a message at the migration destination, avoid the situation that the target migration object fails to address or query the object due to the change of the device where the target migration object is located after migration, and enable the target migration object to have the capability of continuous migration, the address information of the migration source and the target migration object file need to be sent to the migration destination together.

If the address information of the migration source and the target migration object file are mutually independent data, the address information of the migration source and the target migration object file can be sent to the migration destination together when the target migration object file is sent.

In addition, the address information of the migration source may be written into the target migration object file in advance, and then the target migration object file may be sent to the migration destination.

In an embodiment of the present disclosure, in order to increase the speed of data uploading and downloading, the target migration object file is a memory file, that is, the target migration object data is stored by a memory, and at this time, the step S103, that is, the step of sending the target migration object data and the address information of the migration source to the migration destination, may be implemented as:

That is to say, in this embodiment, the target migration object file and the address information of the migration source are transferred through the memories of the migration source and the migration destination, that is, the target migration object file and the address information of the migration source are transferred from the memory of the migration source to the memory of the migration destination.

In an embodiment of the present disclosure, the method further comprises the steps of:

In this embodiment, when there is another data to be migrated, the other data to be migrated is also sent to the migration destination.

In view of the above problem, in this embodiment, a data processing method is proposed, which acquires target migration target data and address information of a migration source, and then sets source address information of the target migration target data as the address information of the migration source, so as to take the address information of the migration source as the source address information of the target migration target when the target migration target sends a message. The technical scheme can not only ensure that most of data to be migrated is insensitive to users under the condition of effective migration, but also meet the requirement of seamless migration of users for objects such as processes to be migrated, programs and the like which depend on connection states and source address information, so that the data service quality can be effectively improved.

In an embodiment of the present disclosure, the data processing method is applied to a physical machine, a physical machine loaded with a virtual machine, or a migration destination device running one or more processes or programs and capable of receiving migration.

In an embodiment of the present disclosure, the migration identification process refers to a process of identifying a migration type to characterize a migration type of migration data, where the migration type may be, for example, a hot migration type, a cold migration type, or the like.

In the foregoing embodiment, after the migration destination obtains the target migration object data and the address information of the migration source, the source address information of the target migration object data may be set as the address information of the migration source, so that when the target migration object sends a message, the address information of the migration source may be used as the source address information of the target migration object, thereby avoiding a situation that the target migration object fails to address or query the object due to a change of a device in which the target migration object is located after migration, and meanwhile, the source address information of the target migration object data is set as the address information of the migration source due to the migration destination, that is, the migration mechanism may be continuously implemented, so that the target migration object has a capability of continuous migration.

In an embodiment of the present disclosure, the step of acquiring target migration object data in response to receiving the data migration message in step S201 may be implemented as:

In order to obtain complete and effective target migration object data, the migration of the data is completed, in this embodiment, the target migration object data is obtained from the received target migration object file by calling an interface of the data exchange device.

In an embodiment of the present disclosure, the step of acquiring address information of the migration source in step S201 may be implemented as:

receiving address information of the migration source; or,

As mentioned above, if the address information of the migration source and the target migration object file are mutually independent data, the address information of the migration source and the target migration object file may be sent to the migration destination together when the target migration object file is sent, and at this time, the migration destination may directly receive the address information of the migration source.

If the migration source writes the address information of the migration source into the target migration object file in advance and sends the target migration object file to the migration destination, the migration destination can obtain the address information of the migration source by analyzing the received target migration object file.

In an embodiment of the present disclosure, the step S202, that is, the step of performing migration identification processing on the target migration target data, may be implemented as:

In order to clarify the migration type of a certain target migration object data and facilitate subsequent message sending or other migration related processing, in this embodiment, hot migration identification information is further set for the target migration object data, for example, if the migration identification information of a certain target migration object data is the hot migration identification information, the subsequent processing may be preferentially performed.

in step S302, the migration destination obtains target migration object data and address information of the migration source, performs migration identification processing on the target migration object data, and sets source address information of the target migration object data as address information of the migration source.

The technical scheme can not only ensure that most of data to be migrated is insensitive to users under the condition of effective migration, but also meet the requirement of seamless migration of users for objects such as processes to be migrated, programs and the like which depend on connection states and source address information, so that the data service quality can be effectively improved.
