The invention discloses a mixed cloud storage method based on file access frequency. The mixed cloud storage method based on the file access frequency includes the following steps: adopting a multi-copy mode storage strategy for a new file when the new file is uploaded to a file system; adopting an erasure code coding mode storage strategy for the file after the file is completely uploaded to the file system; periodically counting access frequency of each file in the file system, and dividing files into three categories which are respectively high frequency files, medium frequency files and low frequency files; adopting different storage strategies for different types of data and different types of files in the system; and dynamically adjusting the storage strategies of the files according to changes of the access frequency of the files in the system. The mixed cloud storage method based on the file access frequency classifies the files by periodically counting the access frequency of each file in the file system, adopts different storage strategies for different types of files, and adjusts the storage strategies of the files according to the changes of the access frequency of the files, and therefore the whole file system wholly improves system storage resource utilization rate on the premises of guaranteeing data reliability and access speed.

The invention provides a multilink self-adaptation domain name server (DNS) parsing method and a device, and relates to the technical field of internet communication. A DNS request module (1) is connected with a DNS parsing module (2), the DNS parsing module (2) is connected with a link analysis module (3), the link analysis module (3) is connected with a route scheduling module (4), and the route scheduling module (4) is connected with a DNS response module (5). The multilink self-adaptation DNS parsing method and the device are capable of self-adaptively conducting domain name resolution adjustment according to the conditions of the link and the server, parsing the most suitable server internet protocol (IP) to a user terminal, guaranteeing user access speed and optimizing an export link, improving visiting performance of the link, combining DNS parsing and link scheduling into one, guaranteeing network visiting speed of the user terminal and achieving optimizing and scheduling to the export link.

The embodiment of the present application belongs to the field of big data, is applied in the field of smart cities, and relates to a page data processing method, including: when receiving a selection instruction sent by the terminal, selecting a crawler operator from the data processing operators deployed on the ETL platform Obtain crawler configuration information according to the configuration command triggered in the crawler configuration page of the terminal; configure the crawler operator according to the crawler configuration information; run the configured crawler operator through the crawler application, and instruct the crawler application The crawled page data is stored in Redis; the page data in the Redis is added to the ETL data flow of the ETL platform; ETL processing is performed on the ETL data flow to obtain inventory data. The present application also provides a page data processing device, computer equipment and a storage medium. In addition, this application also relates to block chain technology, and inventory data can be stored in the block chain. The application improves the processing efficiency of page data.

The invention discloses a data caching method and apparatus. The method comprises the steps of setting two key-value pairs corresponding to data in a cache for a piece of data; storing the data by the first key-value pair, and setting effective time of the data in the cache to be a first preset time; marking pre-failure time of the data by the second key-value pair, and setting the effective time of the data in the cache to be a second preset time, wherein the second preset time is shorter than the first preset time; when a data request is received, performing a search in the cache according to the data request; and if only the first key-value pair is found in the cache, returning a value in the first key-value pair to a requester, reading data of the request from a database again to update the value in the corresponding first key-value pair in the cache, and resetting the corresponding second key-value pair and the corresponding first preset time and second preset time. According to the scheme, the data in the cache can be ensured not to lose efficiency, and the data access speed can be ensured.

The present invention provides a content distribution control method, including: receiving user event information reported by a base station management platform, the user event information includes the user's mobile phone number; based on the user's mobile phone number, querying whether there is a content service platform that matches the user's mobile phone number; When the existence is found out, send a location information request command to the base station management platform to obtain the location information of the target base station accessed by the user's mobile phone number; based on the location information of the target base station, determine the edge server closest to the target base station as the target An edge server; sending a content synchronization instruction to each target content service platform, the content synchronization instruction includes the identification information of the target edge server, so that each target content service platform can send the content to the corresponding target edge server according to the identification information of the target edge server superior. The invention also provides a content distribution control device, which relates to the technical field of communication.

A method for determining a dose distribution and a device for determining a dose distribution, the method comprising: establishing a target geometric model; determining a first area in the target geometric model, and obtaining the dose distribution of the first area based on a Monte Carlo transport simulation method; Acquire the dose distribution of the second area of ​​the target geometric model according to the second method, the second area is an area in the target geometric model except the first area; according to the dose distribution of the first area and the dose distribution of the second area, determine The dose distribution of the target geometric model during radiotherapy. The method adopts the high-precision Monte Carlo method to obtain the dose distribution in the first area, and adopts the rapid dose distribution method in the prior art to obtain the dose distribution in the second area, effectively improving the accuracy of the dose distribution in the first area; At the same time, the acquisition speed of the dose distribution of the entire target geometric model is effectively guaranteed, and the dose distribution of the irradiated part of the patient can be obtained quickly and accurately.
