The invention discloses a distributed data communicating system and a multicast message transmitting method of the distributed data communicating system. The distributed data communicating system comprises a master control card, a switching matrix and line cards. A static multicast table which records the correspondence rules between line card combinations and second-layer addresses is arranged on the switching matrix, and the same correspondence rules, the multicast transmitting table and the correspondence relations between interfaces and the line cards are also arranged on the line cards. After receiving an external multicast message, the line cards inquire a corresponding transmitting interface combination recorded in the multicast transmitting table, determine a corresponding line card combination and then determine a corresponding second-layer address, the second-layer address is packaged to the multicast message and then the multicast message is sent to the switching matrix. The switching matrix transmits the multicast message to a corresponding line card according to the corresponding line card combination obtained through the query of the second-layer address, and the corresponding line card sends the multicast message through the interface of the line card after receiving the multicast message from the switching matrix. By the utilization of the distributed data communicating system and the multicast message transmitting method of the distributed data communicating system, high multicast transmitting performance of the distributed data communicating system can be realized at a low cost.

The application provides a photovoltaic inverter control method and system. The photovoltaic inverter control method comprises the following steps: obtaining the current status value of the photovoltaic inverter, determining the switching frequency corresponding to the current status value through a preset correspondence rule, taking the determined switching frequency as the target switching frequency, and adjusting the current switching frequency of a voltage regulator circuit of the photovoltaic inverter, so as to lower the loss of the voltage regulator circuit of the photovoltaic inverter under the current state, and improve the working efficiency of the photovoltaic inverter under a low light working condition, thus the generating capacity is increased.

In an item selecting apparatus performing a selection of an item to be recommended for each user, it is performed to calculate, with respect to each usage registration of an item by a user, an elapsed value as a difference between a time point of creating the item or staring providing of the item and a predetermined time point, acquire a usage characteristics of each user based on the elapsed value and calculate a freshness value representing a degree of freshness about each item. Further, using correspondence rules of different characteristics corresponding to the usage characteristics, it is performed to calculate a novelty index by applying the freshness value of each item on the correspondence rule corresponding to the usage characteristics of each user (S420), calculate a priority of the item for each user, based on the novelty index (S430) and performing a selection of the item (S440).

The invention discloses a web page processing method, a device, an electronic device and a storage medium. The method comprises the following steps: obtaining a residence time of at least two users for at least one local page area to be adjusted in a target web page, wherein the target web page comprises at least two local page areas; Accumulating the residence time corresponding to the local pagearea to be adjusted to obtain a total residence time corresponding to the local page area to be adjusted; Determining a target display form corresponding to the local page area to be adjusted according to the total residence time and the preset display form correspondence rule; According to the target display form, the display form of the partial page area to be adjusted in the target web page isadjusted. The disclosed embodiment can process the target web page according to the web page operation data of different users, and provide the processed target web page to the user as a user attention distribution map, so that the user can know the attention distribution of all users.

The invention discloses a short-message signature authentication method. The method comprises that a signature authentication request message and the service port number of a short message sent by a short message gateway are obtained; according to a preset correspondence rule between the service port numbers and authentication nodes, an authentication node corresponding to the service port number of the short message is determined in an association information base which stores multiple distributed authentication nodes; association information to be authenticated is extracted from the signature authentication request message of the short message; and the association information to be authenticated is compared with authentication association information stored in the corresponding authentication node to determine a signature authentication result of the short message. The invention discloses a short-message signature authentication device at the same time.

The invention discloses a domain name setting method and device. The domain name setting method comprises the following steps: rewriting a pseudo domain name of a target user in a load balancing server to an intermediate domain name saved in a directory of a real domain name corresponding to the pseudo domain name, and redirecting the intermediate domain name to a spring mvc project; and searching the user identifier of the target user in a database by the spring mvc project according to a preset correspondence rule and the intermediate domain name, rewriting the intermediate domain name to the real domain name according to the user identifier, and redirecting to the real domain name. As the load balancing server can improve the stability of the server, enrich the server functionality, and reduce system resource consumption, and the spring mvc project can forcefully separate input, processing and output of an application program, domain names are not easy to cover; and through the combination of the load balancing server and the spring mvc project, the maneuverability and the security are improved.

The invention relates to a firewall rule matching algorithm based on feature value generation and retrieval. The method comprises the steps of rule set processing and data packet matching. Wherein therule set processing comprises the steps of inputting and initializing a rule set, producing a characteristic value for each rule, and sorting the characteristic values based on the digital size of the rule characteristic values; Wherein the step of matching the data packets comprises the sub-steps of generating characteristic values for the to-be-matched data packets; Carrying out binary search on the generated characteristic values in the rule characteristic value set; If a consistent characteristic value is found, executing a strategy corresponding to the rule; If the data packet cannot befound, matching a rule characteristic value which is greater than the characteristic value of the data packet upwards; Searching a rule matched with the characteristic value of the data packet; If yes, executing a strategy set by the rule, and if not, executing a default strategy. The invention provides a firewall rule matching algorithm which is excellent in performance, controllable in space complexity and friendly to increase and decrease rules.

The invention relates to an ancient document unified logical retrieval method based on index relation, in particular to the logical combination of any logical relations contained in an input text string extracted from text retrieval, and belongs to the technical field of document retrieval. The logical retrieval method concretely comprises the steps of constructing an index system, counting the number of times of a sentence appearing in a fixed sentence length, establishing corresponding rules for logical relations, extracting the logical relation contained in an input text string, and combining rules thereof; displaying results and outputting the six technical steps. According to the logical retrieval method, different retrieval requirements of the user can be satisfied based on the understanding for the logical relation, and user experience is greatly improved.
