Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present invention.
The file retrieval method based on hierarchical heterogeneous topology according to the preferred embodiment of the present invention, as shown in fig. 1 and fig. 2, comprises the following steps:
step S100, receiving a target request of a superior terminal device, wherein the target request comprises an ID of a target subordinate terminal device and a target file to be called.
It can be understood that the upper terminal device is connected to a plurality of lower terminal devices, and when the upper terminal device needs to obtain a certain file (target file) in a certain lower terminal device (target lower terminal device), the upper terminal device sends a target request including an ID of the target lower terminal device and the target file to be called, and the system receives the target request of the upper terminal device.
Specifically, taking two sets of system call files of an upper terminal device and a target lower terminal device as cases, the upper terminal device needs to multiplex the processing process of the last fire accident of the target lower terminal device, and in the process, files such as shooting, transmitting, video recording and the like of the target lower terminal device need to be checked to know the specific situation of accident handling at the time, and then the target request sent by the upper terminal device is received first.
Further, before receiving the target request of the upper terminal device, the method further includes:
and acquiring a query result of the target request in the second file storage service of the superior terminal equipment.
The target request is sent by the Erds-web (scheduling client) of the receiving upper-level terminal equipment, and before the target request is received, the target request is sent to the FSS (second file storage service) of the upper-level terminal equipment, and the query result of the target request in the second file storage service is obtained.
If the target file exists in the second file storage service, the target file is directly obtained in the second file storage service and uploaded to a scheduling client of the superior terminal equipment.
Taking the above processing procedure of the last fire accident of the target lower terminal device for the upper terminal device to multiplex as an example, since the upper terminal device must check and analyze the same file multiple times during the multiplexing, the target file is pulled to the second file storage service (local of the upper terminal device) to be temporarily stored, so that whether the second file storage service contains the target file or not can be checked first when the next request is made, if the target file exists in the second file storage service, the target file is directly acquired in the second file storage service and uploaded to the scheduling client of the upper terminal device, and thus, the bandwidth waste of repeated request public service can be avoided.
And if the target file does not exist in the second file storage service, receiving a target request from the superior terminal equipment, wherein the target request is sent by the first hierarchical scheduling service of the superior terminal equipment.
It may be understood that if the target file does not exist in the second file storage service, it indicates that the target file is not stored locally or has not been acquired recently by the upper terminal device, and thus, a target request from the upper terminal device is received, and the target file is acquired from the lower terminal device according to the target request.
Further, the first file storage service is configured to receive and store the target file uploaded by the scheduling client of the target subordinate terminal device, and upload a message uploaded by the target file to the second hierarchical scheduling service of the target subordinate terminal device through a message queue.
The second hierarchical scheduling service is used for detecting whether the first file storage service can be accessed by the upper-level terminal equipment after receiving the message; if the first file storage service can be accessed by the upper-level terminal equipment, not processing; and if the first file storage service cannot be accessed by the upper-level terminal equipment, downloading the target file, uploading the target file to the public storage service, and deleting the target file after the uploading is successful.
It will be appreciated that the local file storage service should not pay attention to the hierarchical traffic, and the hierarchical scheduling service is unified as an access port for connecting other nodes, so that the hierarchical scheduling service detects whether to upload to the public storage service using the compensation mechanism.
As shown in fig. 3, the following overall process of uploading the file to the public storage service to the target subordinate terminal device is:
and uploading the target file to the first File Storage Service (FSS) by the target subordinate terminal equipment for storage.
The target file is uploaded to a second hierarchical scheduling service (GRDPS) of the target subordinate terminal device via a Message Queue (MQ).
After the second hierarchical scheduling service receives the message, it is detected whether the first file storage service can request a file (i.e., whether it can be accessed by an upper terminal device).
If the first file storage service can be accessed by the upper-level terminal equipment, not processing; and if the first file storage service can not be accessed by the upper-level terminal equipment, downloading the target file, and taking the target file as a temporary file.
And uploading the target file (temporary file) to the public storage service (SFSS), and deleting the target file (temporary file) by the second hierarchical scheduling service after the uploading is successful.
Step 200, a first file storage service of the target subordinate terminal equipment is found in the hierarchical heterogeneous topology service according to the ID of the target subordinate terminal equipment, and a first access request is sent to the first file storage service.
The step of finding the first file storage service of the target subordinate terminal equipment in the hierarchical heterogeneous topological service according to the ID of the target subordinate terminal equipment specifically comprises the following steps:
and searching the address of the target subordinate terminal equipment in the child nodes of the topological graph of the hierarchical heterogeneous topological service according to the ID of the target subordinate terminal equipment.
And determining the address of the first file storage service according to the address of the target subordinate terminal equipment.
The hierarchical heterogeneous topology service is used for representing and updating the topological relation between the upper-level terminal equipment and the lower-level terminal equipment (the topological relation refers to the mutual relation among all spatial data meeting the principle of topological geometry), namely, the adjacency, association, inclusion and communication relation among entities represented by nodes, arcs and polygons.
And after searching the address of the target subordinate terminal equipment, sending a first access request to the first file storage service.
And sending a first access request to the first file storage service, wherein if the first access request can be accessed, the firewall of the lower-level terminal equipment does not reject the upper-level terminal equipment, and the first file storage service is directly accessed to acquire the target file.
Step S300, if the first file storage service accepts the first access request, the target file is obtained from the first file storage service, the target file is sent to the superior terminal equipment, and otherwise, a second access request is sent to a public storage service.
It will be appreciated that when the first access request is denied, a second access request is sent to the public storage service; the first access request and the second access request both contain the ID of the target subordinate terminal device and the target file.
Because the upper terminal device and the target lower terminal device actually belong to different systems, the firewall of the target lower terminal device generally refuses the request of the head office, and the public storage server is opened to the head office and the subsidiary for use together, the application uses the public storage server as a transfer station to solve the problem of file isolation under the hierarchical heterogeneous system.
And step 400, after the public storage service receives the second access request, acquiring the target file from the public storage service, and sending the target file to the superior terminal equipment.
Specifically, after the public storage service receives the second access request (i.e. after the firewall of the target subordinate terminal equipment refuses the request of the superior terminal equipment), the target file is found in the public storage service according to the target file in the second access request and downloaded, and the target file is sent to the superior terminal equipment.
The sending the target file to the superior terminal device specifically includes:
and sending the target file to a superior terminal device through the first hierarchical scheduling service and the second file storage service.
The second file storage service temporarily stores the target file according to preset time.
Taking the processing procedure of the last fire accident of the target lower terminal equipment to be re-coiled by the upper terminal equipment as an example, the upper terminal equipment can certainly check and analyze the same file for a plurality of times during the re-coiling, so that the target lower terminal equipment is temporarily stored in the local temporary storage of the upper terminal equipment, the bandwidth waste caused by repeated public service request can be avoided, and the acquisition efficiency of the target file is improved.
Further, as shown in fig. 4, the overall process of the upper terminal device obtaining the file of the target lower terminal device is as follows:
the superior terminal device sends a target request to the second File Storage Service (FSS) to acquire a target file.
And the second file storage service queries a target file according to the target request, and if the target file exists in the second file storage service, the target file (image and sound recording) is directly acquired in the second file storage service and uploaded to a scheduling client (Erds-Web) of the upper terminal equipment for playing.
And if the target file does not exist in the second file storage service, receiving a target request from the superior terminal equipment.
After the first hierarchical scheduling service (GRDPS) receives the target request from the second file storage service, a target file of a corresponding subordinate terminal device (target subordinate terminal device) is retrieved according to the target request.
The first hierarchical dispatch service sends the target request to the hierarchical heterogeneous topology service (OSS) via a long connection of RPC (remote procedure call).
The hierarchical heterogeneous topology service finds the address of the lower-level terminal device corresponding to the ID in the topology relationship according to ID (PlatformId) of the target lower-level terminal device in the target file, finds the second hierarchical scheduling service according to the address of the lower-level terminal device, and sends the first access request to establish connection with the second hierarchical scheduling service (GRDPS of the lower-level terminal device).
And after the connection is established, judging whether the first file storage service of the target subordinate terminal equipment can be accessed.
If yes, the target file is obtained from the first file storage service, and the target file is sent to a dispatching client of the superior terminal equipment.
If not, the second access request is sent to the public storage service (SFSS), the target file is obtained from the public storage service, the target file is sent to the dispatching client of the superior terminal equipment through the first hierarchical dispatching service and the second file storage service, and meanwhile, the second file storage service temporarily stores the target file according to preset time.
Therefore, when the upper terminal equipment and each lower terminal equipment are isolated by the network, the invention can tell the hierarchical heterogeneous topological service to avoid the upper terminal equipment directly requesting the file stream to download the file when the files of the lower terminal equipment cannot be accessed, and the public storage server is used as a transfer station to solve the problem of file isolation under the hierarchical heterogeneous system, thereby effectively improving the file retrieval efficiency and avoiding the waste of bandwidth.
Further, as shown in fig. 5, based on the file retrieving method based on the hierarchical heterogeneous topology, the present invention further correspondingly provides a file retrieving system based on the hierarchical heterogeneous topology, where the file retrieving system based on the hierarchical heterogeneous topology includes:
a target request receiving module 51, configured to receive a target request from a superior terminal device, where the target request includes an ID of a target subordinate terminal device and a target file to be fetched;
