The invention relates to a method for changing the center frequency of a filter with a superconducting microstrip structure by adopting mask overlay, and belongs to the technical field of microwave communication equipment. The method comprises the following steps of: performing primary simulation designing on a superconducting filter circuit structure according to required filter indexes, manufacturing the designed filter by adopting high-resolution photoetching and ion beam etching processes, comparing a tested response curve with a simulated response cure, modifying an effective dielectric constant in simulation parameters, performing secondary simulation, keeping an inter-resonator distance unchanged, decreasing the length of each resonator in the filter to make the center of a filter circuit with a decreased length reach a required frequency point; manufacturing a mask plate for the overlay, and exposing a cut part in a secondarily-simulated filter circuit pattern; and photoetching and etching the manufactured filter to obtain the filter with required center frequency. The method is accurate in result and low in cost; and simultaneously, good passband response is ensured, and the performance of the filter meets the requirements of actual application.

A method and system for processing cloud cluster abnormalities caused by private cloud viruses. The method includes: setting a network traffic probe for each cloud computing node of the private cloud computing cluster, monitoring the traffic of the corresponding cloud computing node through the network traffic probe; judging whether the cloud computing node receives consecutive request reports with the same characteristics text; if receiving consecutive request messages with the same characteristics, it is judged whether the number of received continuous request messages with the same characteristics is equal to or greater than the preset value; if the number of request messages is equal to or greater than the preset value, Then check the status of the virtual computer that sends out continuous request messages with the same characteristics; when it is detected that the system resources of the virtual computer are abnormal, close the network of the virtual computer. The invention can reduce the use of extra system resources, reduce equipment purchase and maintenance costs, does not affect bandwidth, and can improve user experience.

The invention relates to a wired network monitor system, which comprises M independent information collectors, a data center and M independent monitored network units, wherein the output terminal of each independent information collector is connected with the input terminal of the data center; the input terminals of the M independent information collectors are connected with the output terminals of the M independent monitored network units; each independent monitored network unit is connected with N independent users; and the N independent users corresponding to each monitored network units are different from the N independent users corresponding to other monitor network units. The wired network monitor system has the advantages that the data collection and analysis is achieved by the information collectors at the outlet of each network unit by adopting a multi-step data processing and centralized control manner; and the information collection policy and the data summarization are achieved by the data center, so that the processing of massive data is distributed to different units to achieve maximally centralized control, thereby reducing the data quantity to be stored. The wired network monitor system can work normally only using a simple network connection, and has the advantages of convenient implementation and simple maintenance.
