Fig. 1 schematically illustrates an application scenario of an information processing method and a system thereof according to an embodiment of the present disclosure.
The information processing method and the system thereof provided by the embodiment of the disclosure can realize that the client accesses the data provided by the FTP service through the virtual machine. As shown in fig. 1, a virtual machine 102 is configured on a physical machine 101, and the virtual machine 102 can provide an FTP service to the outside, for example, a data file is provided on an FTP shared directory for access, where the data file is stored on a block device in the virtual machine 102, the block device is also referred to as a data block, the data block stores the data file in a block storage area with a fixed size, each data block has a corresponding address, and the data blocks are relatively independent, and the block device of the virtual machine 102 is correspondingly mapped to a file in a file system of the physical machine 101, that is, an image file of the virtual machine. The client 103 can access a specified data file among data files provided by the FTP service through the virtual machine 102.
It should be noted that the number of hosts, virtual machines, and data files in the application scenario of this embodiment is merely illustrative, and is not intended to limit or narrow the scope of the present disclosure, and any number of hosts, virtual machines, and data files may be provided according to implementation needs.
Fig. 2A schematically shows a flow chart of an information processing method according to an embodiment of the present disclosure.
As shown in fig. 2A, the information processing method of the embodiment of the present disclosure is applied to a virtual machine capable of providing an FTP service, and the method may include operations S210 to S220, in which:
in operation S210, a first data request sent by a client for instructing to acquire a specified data file is received.
In operation S220, in response to the first data request, the logical address of the specified data file is returned to the client, so that the client can send a second data request to the physical machine installed with the virtual machine based on the returned logical address, thereby enabling the physical machine to respond to the second data request and find the specified data file according to the physical address having a mirror mapping relationship with the logical address, and send the found specified data file to the client.
FTP is one of the protocols in the TCP/IP suite, and is an abbreviation of File Transfer Protocol in English. The protocol is the basis of Internet file transmission, and consists of a series of specification documents, and aims to improve the sharing of files, provide indirect use of remote computers and enable a storage medium to transmit data reliably and efficiently for users. In brief, FTP copies files from a remote computer (virtual machine) to its own computer (physical host), called "download" files. If a file is copied from its own computer to a remote computer, it is called an "upload" file. In the embodiment of the present disclosure, a client downloads a data file provided by an FTP service through a virtual machine, and the uploading process may be correspondingly expanded according to the spirit of the embodiment of the present disclosure, which is not described herein again.
For a virtual machine capable of providing an FTP service, taking an example that a client downloads a data file 1 in an FTP shared directory of the virtual machine as shown in fig. 1, a data file transmission process in the related art and a data file transmission process in an embodiment of the present disclosure are described in detail.
In the related art, a client downloads a data file 1 in a virtual machine FTP shared directory as shown in fig. 1, and the flow and specific steps of data file transmission are roughly as follows:
1. a client sends a data reading request for downloading a data file 1;
2. the FTP service sends a read request to a file system of the virtual machine;
3. a block device of a file system initiates a data reading request to a physical machine;
4. the physical machine reads data from the disk and returns the data to the virtual machine;
5. the virtual machine feeds the data back to the client to complete the data downloading task of the client.
In other words, in the related art, data read by the client needs to undergo one conversion from the virtual network card to the physical network card before being sent to the client, that is, the data undergoes two disk reads and two memory copies.
According to the embodiment of the disclosure, by extending the existing FTP protocol, the FTP service on the virtual machine provides the client with the location information of the data file to be accessed, that is, the logical address information, the logical address has a mirror image relationship with the physical address of the data file stored on the physical machine, when the client sends a second data request containing at least the logical address of the data file to the physical machine installed with the virtual machine based on the logical address returned by the virtual machine, the physical machine responds to the second data request, finds out the designated data file according to the physical address having a mirror image mapping relationship with the logical address, and sends the found designated data file to the client.
In the embodiment of the present disclosure, a client downloads a data file 1 in a virtual machine FTP shared directory as shown in fig. 1, and the flow and specific steps of data file transmission are substantially as follows:
1. a client sends a data reading request for downloading a data file 1;
2. the FTP service of the virtual machine feeds back the logic address information of the data to the client;
3. the client side directly sends a data reading request to the host according to the fed-back logical address information;
4. the host analyzes the physical address information according to the logical address information, and reads the data on the disk and sends the data to the client.
In other words, in the embodiment of the present disclosure, the data read by the client is that the physical host resolves the received logical address into a physical address, and the data is read out according to the physical address and sent to the client, so that a transmission process of the data from the host to the virtual machine is omitted.
According to the embodiment of the disclosure, after the data request sent by the client for indicating to acquire the designated data file is received, the technical scheme that the existing FTP protocol is expanded to enable the virtual machine to provide the client with the location information of the data file to be accessed is adopted, so that the client can directly send the data request to the physical machine based on the logical address, the technical problems that the data file needs to go from the host to the virtual machine in the data file transmission process and then from the virtual machine to the client for two times of reading and copying in the related technology are at least partially overcome, the processes of reading and copying the data from the host to the virtual machine can be at least saved, the data transmission time is effectively shortened, the technical effects of improving the data transmission speed and efficiency are achieved, and the user experience is greatly improved.
Fig. 2B schematically illustrates a flow diagram for responding to a first data request and returning a specified logical address of a data file to a client according to an embodiment of the present disclosure.
In this embodiment, operation S220 described with reference to fig. 2A (i.e., returning the logical address of the specified data file to the client in response to the first data request) may include operations S221 to S223. As shown in fig. 2B:
in operation S221, identification information of the designated data file is acquired in response to the first data request.
In operation S222, a logical address of the specified data file on the virtual machine is acquired according to the acquired identification information.
In operation S223, the logical address of the specified data file is returned to the client.
It should be noted that the identification information of the data file may include, but is not limited to, a name of the file and an identification (inode) of the file in the file system, and an address of the file in the underlying file system may be obtained according to the identification information, for example, an attribute extension interface may be called, the inode is used as an address of the data file in the file system for Key obtaining request, and a method of specifically obtaining a logical address of the data file on the virtual machine is not limited in this disclosure.
According to the embodiment of the disclosure, after receiving a data request sent by a client, a virtual machine does not send the data request to a file system any more, but feeds back a logical address of the data file on the virtual machine to the client, so that the client directly sends the data request and the logical address to a physical host based on the logical address, and the physical machine directly sends the data file to the client.
Fig. 3 schematically shows a flow chart of an information processing method according to another embodiment of the present disclosure.
As shown in fig. 3, the information processing method is applied to a client, and the method may include operations S310 to S340, in which:
in operation S310, a first data request is transmitted to a virtual machine capable of providing an FTP service to acquire a designated data file.
In operation S320, a logical address of a specified data file returned by the virtual machine in response to the first data request is received.
In operation S330, a second data request is sent to the physical machine installed with the virtual machine based on the logical address returned by the virtual machine, so that the physical machine can find out a specified data file according to the physical address having a mirror mapping relationship with the logical address in response to the second data request, and send the found specified data file to the client.
In operation S340, a designated data file transmitted by a physical machine is received.
It should be noted that, for the client, if the data file provided by the FTP is to be read by the virtual machine, two data requests need to be sent, where a first data request is sent to the virtual machine capable of providing the FTP service, a received logical address of a specified data file returned by the virtual machine in response to the first data request is received, a second data request is sent to the physical machine installed with the virtual machine capable of providing the FTP service, and the received data file is the specified data file found by the physical machine according to the second data request.
According to the embodiment of the disclosure, by adopting the technical scheme that the client sends the data request twice, the physical machine can find out the data file based on the logical address of the request data file sent by the client and directly sends the requested data file to the client, so that the technical problems of low efficiency, low speed and the like caused by the fact that the physical machine needs to send the data file to the virtual machine and then the virtual machine sends the data file to the client in the related technology can be at least overcome, and the technical effects of improving the data transmission efficiency and improving the user experience are achieved.
Fig. 4A schematically illustrates a flow chart of an information processing method according to still another embodiment of the present disclosure.
As shown in fig. 4A, the information processing method is applied to a physical machine in which a virtual machine capable of providing an FTP service is installed, and the method may include operations S410 to S430, in which:
in operation S410, a second data request sent by the client is obtained.
In operation S420, in response to the second data request, the specified data file is found according to the physical address having the mirror mapping relationship with the logical address.
In operation S430, the found designated data file is transmitted to the client.
It should be noted that, for a physical machine installed with a virtual machine capable of providing an FTP service, first, a data request of a logical address of a data file fed back by the virtual machine sent by a client needs to be acquired, and the logical address of the data file in the data request is analyzed to obtain a physical address having a mirror image mapping relationship with the logical address, that is, an address of a data block of the data file on a mirror image medium, and the data file is read and directly sent to the client instead of sending the data file to the virtual machine and sending the data file to the client by the virtual machine.
According to the embodiment of the disclosure, after the physical machine is used for acquiring the data request sent by the client, the logical address in the data request is analyzed, the physical address having a mirror image mapping relation with the logical address is acquired, and the data file is read according to the physical address and is directly sent to the client, so that the physical machine can directly speak the requested data file and send the requested data file to the client without passing through the intermediate transmission process of the virtual machine, the technical problems of slow data transmission and low efficiency caused by the fact that the data file needs to be transmitted twice in the related art are at least partially overcome, the technical effect of improving the data transmission efficiency is achieved, and meanwhile, the burden of equipment can be reduced.

In operation S422, a specified data file corresponding to the physical address is found.
In operation S423, the found designated data file is transmitted to the client.
After receiving a second data request sent by the client, the physical machine, according to the physical address of the specified data file on the physical machine in the logical address mirror mapping relationship of the data file specified by the data request on the virtual machine, for example, a standard extended data interface (getxattr) can be called, and according to key: the GET _ ADDR is in a local file system (EXT3/EXT4), the address, namely the physical address, of the data block of the data file on the mirror image medium is obtained, the corresponding data file can be found according to the physical address, and finally the found data file is sent to the client. It should be noted that, the embodiment of the present disclosure is not limited to a method for obtaining a physical address having a mirroring relationship corresponding to a logical address according to the logical address.
Through the embodiment of the disclosure, the physical host can obtain the physical address corresponding to the logical address of the data file on the virtual machine, and find the designated data file according to the physical address, and the physical machine can directly send the data file to the client without the transfer of the virtual machine, so that the frequency of data conversion from the virtual network card to the host physical network card when the virtual machine transmits data outwards is effectively reduced, the efficiency of data transmission is improved, and the user experience is better.
