In the embodiment of the present application, the data service may refer to operations of storing, deleting, modifying, marking, analyzing, and the like, on data.
The embodiment of the application provides a traffic management system.
Referring to fig. 1, fig. 1 is a schematic view of a scenario of a traffic management system according to an embodiment of the present application, where the system may include terminals and servers, and the terminals, the servers, and the terminals and the servers are connected and communicated through internet composed of various gateways, and the like, where the application scenario includes a front-end device 101, a first data center 102, a second data center 103, a service server 104, and a configuration server 105, where:
the front-end apparatus 101 may include video and image capturing apparatuses and the like provided at respective checkpoints.
The first data center 102 and the second data center 103 may be independent servers, or may be a server network or a server cluster formed by servers; for example, the first data center 102 and the second data center 103 described in the embodiments of the present application include, but are not limited to, computers, network hosts, database servers, large data server clusters, storage servers, and Cloud servers formed by application servers or multiple servers, where the Cloud servers are formed by a large number of computers or network servers based on Cloud Computing (Cloud Computing).
In the embodiment of the application, since the storage space occupied by the picture data is large, the first data center 102 with a large storage space is used for storing the picture; since the storage space occupied by the text data is small, the second data center 103 having a small storage space is used to store the local storage path of the picture. The storage mode greatly reduces the storage pressure of the system and improves the usability of the system.
In the embodiment of the present application, the server and the front end may implement communication through any communication manner, including but not limited to mobile communication based on the third Generation Partnership Project (3 GPP), Long Term Evolution (LTE), Worldwide Interoperability for Microwave Access (WiMAX), or computer network communication based on the TCP/IP Protocol Suite (TCP/IP), User Datagram Protocol (UDP), and the like. As shown in the traffic management system in fig. 1, the front-end device 101 may respectively interact with the first data center 102, the second data center 103, and the configuration server 105, and the first data center 102 and the second data center 103 respectively interact with the service server 104, where:

Because the storage path belongs to text information, the difference between the size of the text information and the size of the picture information is very large, and the difference can generally reach the ratio of 1 to 1000, and therefore compared with the prior art, the storage space is greatly saved by the storage mode.
When the first data center 102 fails to operate normally, the communication between the front-end device 101 and the first data center 102 is interrupted, at this time, the front-end device 101 does not receive a picture uploading response returned by the first data center 102, and the front-end device 101 marks a traffic management picture which does not receive the picture uploading response as an abnormal picture; after the failure is resolved and the first data center 102 resumes operating, the front-end device 101 will take the abnormal picture as a picture to be uploaded, and resend the picture uploading request to the first data center 102, the first data center 102 receives the picture uploading request, stores the received picture, and sends the abnormal picture uploading response to the front-end device 101 at the same time, and the front-end device 101 receives the picture uploading response of the abnormal picture and marks it as an uploaded picture, so that the abnormal picture will not occupy the storage space of the first data center 102 because of being repeatedly uploaded. In addition, when the first data center 102 fails, the service server 104 cannot send a service request to the first data center 102, so that the service server 104 sends the service request to the second data center 103, requests to call and analyze the traffic management picture corresponding to the local storage path stored therein, and after receiving the service request, the second data center 103 performs corresponding operation and sends a processing result to the service server 104.
When the second data center 103 fails to operate, the first data center 102 still operates normally, but at this time, an upload failure occurs in a local storage path uploaded to the second data center 103 by the front-end device 101, in this case, the front-end device 101 does not receive a path upload response sent by the second data center 103, and at this time, the front-end device 101 marks the local storage path that does not receive the path upload response as an abnormal path; after the failure is resolved and the second data center 103 resumes operation, the front-end device 101 may receive a path upload response again at a certain time, at this time, the front-end device 101 may use the abnormal path as a path to be uploaded and upload the abnormal path to the second data center 103, and after the upload is successful, the front-end device 101 may receive the path upload response of the abnormal path and mark the path upload response as an uploaded path, so that the local storage path may not occupy the storage space of the second data center 103 because of being repeatedly uploaded. In addition, when the second data center 103 fails, the service server 104 cannot send a service request to the second data center 103, so that the service server 104 sends the service request to the first data center 102, requests to call and analyze the traffic management picture stored therein, and after receiving the service request, the first data center 102 performs a corresponding operation and sends a processing result to the service server 104.
