The invention discloses a cache management method and device, equipment and a storage medium, and belongs to the technical field of storage. The embodiment of the invention provides a method for caching and eliminating material resources of a virtual scene based on temperature information, adopts the temperature information to represent the probability that the material resources are accessed in the virtual scene, uses the positions, corresponding to the temperature information, in the cache queue for caching the material resources, and conducts cache elimination on the cache queue according to the sequence of the positions from back to front. In this way, the cold resources of the virtual scene are eliminated first, and then the hot resources of the virtual scene are eliminated. On one hand, by prolonging the residence time of the hotspot resources in the cache, the probability of hitting the cache when the hotspot resources are accessed is improved, so that the cache hit rate is improved, and the problem of cache pollution is solved. And on the other hand, the cold resources in the cache are removed as soon as possible, so that the cache space is saved.

The invention discloses an intelligent contract execution method and system in a blockchain, and electronic equipment. The method comprises the following steps: after a target proposal reaches a consensus, a blockchain node calls a smart contract to execute a target transaction in the target proposal, and stores a transaction execution result of the target transaction generated in an execution process in a first cache; if the target transaction is successfully executed, the blockchain node stores a transaction execution result of the target transaction stored in the first cache into a second cache; and the blockchain node performs a block writing operation based on the transaction execution result in the second cache.

The invention discloses a method and system for accessing information. The method includes the steps of caching the information in a data source according to the one-to-one mapping relation, caching same contents into certain edge accessing servers, and storing one-to-one mapping relations between the information contents and the edge accessing servers to form a mapping relation table; based on the mode, when accessing requests of terminals are received, if requested information contents are contained in the table, representing that requested target information is cached in the servers, and directly obtaining the servers where the target information is cached from the table; if the requested information contents are not contained in the table, calculating the edge accessing servers corresponding to the target information, caching the target information in the data source into the servers, and meanwhile adding mapping relations between the information and the servers into the mapping relation table; then responding to the terminals, and informing the terminals of the servers where the target information is cached to enable the terminals and the servers to be in communication to achieve information accessing. By means of the method and system, multiple copies of the same contents are avoided, and cache space is saved.

The invention provides a method for multiplexing hybrid automatic repeat request (HARQ) processes and belongs to the technical field of mobile communication. According to the method, at a user side, the HARQ processes are divided into physical HARQ processes and logic HARQ processes, and a physical process storage table and a logic process storage table are established. A state of each physical HARQ process, a mapping relationship between the physical HARQ processes and the logic HARQ process, and space addresses for caching soft bits are stored in the physical process storage table. NDIs (NewData Indicators) expected by the user side are stored in the logic process storage table. When downlink transmission receiving of a user is unsuccessful, the available physical processes are selectedfor caching the soft bits, the mapping relationship between the logic processes and the physical processes is recorded, and the expected NDIs of the logic processes are kept unchanged. When the downlink transmission receiving is successful, only the expected NDIs corresponding to the logic HARQ processes are overturned, and the soft bits are not cached. According to the method, the number of theHARQ processes and cache space required by the user side are reduced.

The embodiment of the invention provides a file server, a terminal and a file subpackage transmission method. The method comprises the following steps: a source terminal determines the number of file fragments to be divided according to a file division strategy, and uploads the file name and number information onto the file server; the source terminal divides the file according to the file division strategy, and assigns fragment sequence numbers to the divided fragments; each fragment and the sequence number thereof are encapsulated in a subpackage file to be uploaded to the file server; then, a file receiving condition inquiry request is transmitted to the file server; the source terminal re-transmits a corresponding subpackage file after receiving retransmission information returned from the file server; and the retransmission information is determined by the file server according to the file name, the fragment sequence number carried in each subpackage file and the number information. Through adoption of the method, time for transmitting the file can be saved, the file transmission efficiency is improved, and bandwidth and system resources are saved.

The invention discloses a method and equipment for sending signaling tracing message. The method comprises the following steps of: generating the signaling tracing message; storing the signaling tracing message and task identification of corresponding tasks in a cache region; if the signaling tracing message corresponding to multiple tasks is determined, storing a piece of signaling tracing message, and recording to the task identification of each task corresponding to the signaling tracing message; and packing the signaling tracing message in the cache region in set time according to the task identification, and sending the packed signaling tracing message to an acquisition entity specified by a tracing server, wherein the packed signaling tracing message is the signaling tracing message generated by the traced task created by the server. Congestion of networks in a certain time period is not caused. Meanwhile, timely discovery of network element faults is not affected. The signaling tracing message is not repeatedly stored in the cache region, and the traced message is more comprehensive due to the storage of maximum capacity.

The invention discloses a data storage method. The data storage method comprises the steps that when a data writing instruction is detected and received, logic page addresses of data to be written and a number of pages of the data to be written are determined according to the received data writing instruction, a physical page address corresponding to each logic page address of the data to be written is determined, and the data to be written comprise multi-logic page data and signal-logic page data; the determined logic page addresses, the physical page addresses and the number of pages are taken as a mapping entry and stored a record block mapping table in a relevance way.

The present invention relates to a network coding and path protection-based optical network single-link fault protection method. According to the method, a 1+1 path protection and network coding-combined method is adopted, relay nodes are responsible for network coding; when overflow occurs on the buffer of a certain pair of nodes, a data packet which has been buffered for the longest time is transmitted along a protection path, and a 1+1 path protection method is used; and the packet header of the data packet is provided with an identification bit which is used for indicating whether the data packet has been subjected to network coding, if the identification bit is 1, it is indicated that the data packet has been subjected to network coding, and the identification bit is 0, it is indicated that the data packet has not been subjected to network coding, and a destination node receives the data packet transmitted along the protection path, reads packet header information, judges whether the data packet has been subjected to network coding and performs corresponding processing. With the network coding and path protection-based optical network single-link fault protection method of the invention adopted, the normal transmission of data in a network can be ensured when a single-link fault occurs on network links, and redundant data packets generated in the network due to a protection mechanism can be decreased.
