According to the top heat dissipation type liquid cooling container and the application control method thereof, the cooling tower container top arrangement design is adopted, a CDU module is omitted, the overall cost is reduced, more Tanks can be deployed in the spare space after the CDU module is omitted, and the computing power of a single liquid cooling container is greatly improved. The cooling tower is compact in structural form, low in space occupancy rate, higher in integration degree and good in universality and reliability, and the ground space of the cooling tower is saved. After a certain cooling tower fails, normal operation of other devices is not affected, and the disaster recovery capacity is improved. The cooling tower and the Tank carry out heat exchange one by one, the heat dissipation efficiency is higher, the number of water cooling pipelines is smaller, and the integration degree is higher.

The application discloses a kind of key efficient management methods based on national secret algorithm, it is related to information security and data storage technical field, including the following steps: step one, generating master key MK and storing in secure encryption hardware, using master key is encrypted by national secret algorithm and is transformed to obtain protection key PK1;Step two, administrator inputs protection password and the key ciphertext data needing storage, and uses SM3 algorithm to calculate the input protection password, obtains protection key PK2;Protection key and national secret algorithm are used to encrypt the key data, wherein, the generation mode of protection key PK1 is fixed and depends on master key and protection factor S, the generation mode of protection key PK2 is determined by the password input by administrator, the complete independent controllable of protection key and encryption algorithm is realized, at the same time, the storage of key and the access of key are operated in the form of ciphertext, greatly improve the security of key.

The invention provides a request processing method and device, electronic equipment, a storage medium and a program product, and relates to the technical field of software architecture under Java ecology, and the method comprises the following steps: receiving a request, packaging the request into a Fiber task, and carrying out asynchronous processing; in the Fiber task asynchronous processing process, the dependency service is accessed in an asynchronous non-blocking mode, and a user response is formed according to dependency data and task logic; and writing back the user response to the user side in an asynchronous non-blocking mode. Through the technical scheme in the embodiment of the invention, the system resource utilization rate and the disaster recovery capability in a high-concurrency scene can be improved, and the service deployment cost is reduced.

The application discloses a seamless degradation method for streaming speech translation, comprising the following steps: constructing an audio buffer queue independent of a speech recognition engine and a translation engine on a server, and appending all received audio streams to the audio buffer queue; constructing a speech recognition degradation link comprising at least two speech recognition engines, and a translation degradation link comprising at least two translation engines; if the current speech recognition engine fails, starting the next priority speech recognition engine, and migrating the session core metadata of the audio buffer queue to the new engine through a state transition algorithm, so that the new engine continues to recognize from the queue breakpoint; if the current translation engine fails, retaining the original text and context information of the current translation task, starting the next priority translation engine, and injecting the original text and context information into the new engine for silent retry. Seamless switching is realized when the underlying service fails.

The invention discloses a data intelligent encryption storage protection implementation method for image cloud, and relates to the technical field of data security, and the method comprises the steps: obtaining an image service data set, distributing a data identifier for each piece of image service data, summarizing the image service data set and the corresponding data identifier, and forming a to-be-encrypted list; generating a random seed and a timestamp for each piece of image service data in the to-be-encrypted list, combining the random seed and the timestamp according to a splicing rule to form a data key of the current image service data, and summarizing the data identifier, the random seed and the timestamp to form a key metadata set; and based on the data key corresponding to each data identifier in the key metadata set, performing symmetric encryption operation on the corresponding image service data to generate initial encrypted data. According to the invention, the independent and unique data key is generated for each piece of image service data, so that the permeability resistance and disaster tolerance of the image cloud data storage system are improved.

The embodiment of the invention discloses a method and a device for realizing data synchronization among multiple nodes based on a block chain, a storage medium and electronic equipment, when a target node on the block chain receives block data sent by a first node, the stored data stored by the target node is firstly updated, and then the data is compared with other adjacent nodes, so that the data synchronization among the multiple nodes is realized. The data of the adjacent nodes are synchronized to be consistent with the data of the target node, and even the data of other nodes of the block chain are synchronized to be consistent.
