Currently, many cross-network data exchange fields, typical work scenarios such as the Internet, work network, private network and other multiple network domains deploy cross-network data exchange systems. The cross-network data exchange system is based on one-way transmission equipment to achieve the exchange of business and files in different office network areas (hereinafter referred to as network domains or network segments) isolated from the network. With the increasing standardization of network security management, three or more multi-domain business systems will also appear.

[0026] It should be understood by those skilled in the art that the embodiments described below are only preferred embodiments of the present disclosure, and do not mean that the present disclosure can only be implemented through the preferred embodiments. The preferred embodiments are only used to explain the technical principles of the present disclosure, and are not used to limit the protection scope of the present disclosure. Based on the preferred embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present disclosure.

[0027] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0028] 1. In order to clearly describe the technical solutions of the embodiments of the present application, some of the terms and technologies involved in the embodiments of the present application are briefly introduced below:

[0029] The cross-network exchange system node deployment service includes data collection service and data routing service; among them, the data collection service is responsible for collecting node data information, and the node data information includes but is not limited to device resource status, network status, program running status, data exchange link status, business file transmission information, etc.

[0030] The data routing service is responsible for forwarding the collected data in the current node to the next node. The data routing service relies on the cross-network data exchange system to forward data.

[0031] The present application deploys relevant service data exchange nodes on each cross-network data exchange node in each network domain, including but not limited to data exchange systems, one-way transmission equipment, etc., wherein the one-way transmission equipment includes two nodes, the sending end and the receiving end of the transmission equipment.

[0032] The collected data of each node of the cross-network data exchange system is finally gathered at the end node. Statistical analysis is performed on the end node to generate business diagnosis results, which are displayed through the unified operation and maintenance supervision system, realizing the function of supervising systems in multiple network domains at a single node, including the system status, service status, file loss status, etc. of each node.

[0033] The technical solution proposed in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0034] The embodiment provides a cross-segment monitoring and detection method based on a unidirectional transmission device, such as Figure 1 As shown, the method provided in the embodiment of the present application mainly includes the following steps:

[0035] Step 110: collect node data of the network segment corresponding to the inter-network switching system node through the starting inter-network switching system node on the preset transmission link, add node information and routing information, generate a data file data, add it to the preset data file set, and transmit the preset data file set to the unidirectional transmission device corresponding to the routing information.

[0036] It should be noted that relevant services are deployed on each cross-network data exchange node in each network domain. The cross-network exchange system node deployment services include data collection services and data routing services; among them, the data collection service collects the information required by this node, including collectors and collection agents. Different types of collectors collect different types of information, such as device status, network status, program status, data link status, business file transfer information, etc.

[0037] Specifically, multiple collectors collect different types of information and write them into collection files in a specified format.

[0038] The collection file name format is: collection type-date.accumulated value.json. The accumulated value (n) starts from 1, and increases by 1 each time a file is generated. It is reset to zero every day and starts accumulating from 1 again. For example, the file transfer information is written to the file filetrans-2024-08-08.10.json.tmp. During the process of writing files, the files all end with .tmp.

[0039] The collection file supports controlling the size of a single collection file from two dimensions: time or number of records. Both dimensions are configurable, for example, the time dimension is set to 1 minute and the record number threshold is set to 100.

[0040] When the threshold configured in any dimension is reached first in the two dimensions, the collection file of the cumulative value n is written to the end, the file is renamed, the .tmp suffix is ​​removed, and the collection file is generated.

[0041] The cumulative value n of the new acquisition file is incremented, that is, the acquisition data will be written into another acquisition file.

[0042] The collection of device status, network status, program status, and link status can be done through the corresponding collectors. The collected program list status indicators, link port list, etc. can all be dynamically configured.

[0043] The collection of business file transfer logs is done through a file transfer collector, and the collection methods include but are not limited to collecting through log files of the transfer business. It can also be collected through other methods that can filter out file transfer records.

[0044] For example, through business log file collection, you can monitor the log files of the transmission business and collect file transfer records through the embedded point marks in the log files.

[0045] If there are file transfer records in Kafka messages, the file transfer records can be collected through Kafka messages.

[0046] The collected information varies depending on the type of collector, but it basically needs to cover the following general information: system name, subsystem name, module, transmission status, collection time, log level, collection identifier, summary, description, status, etc. Personalized information refers to CPU usage, memory usage, program status, link channel status, file sender, file receiver, file name, file unique ID, etc.

[0047] Each node has a collector, which can be dynamically set according to the collection parameter configuration, such as the type of information collected, the frequency of collection, etc.

[0048] The node information includes the node name, node code, node IP, node packaging time, etc.

[0049] The routing information includes the next node and target node information to which the file is to be transferred.

[0050] The information collected by multiple collectors is processed by the collection agent, which periodically reads all the collection files (.json format files) in the directory, adds the corresponding node information and routing information, and generates the data file data.

[0051] In addition, in the step, the preset data file set is transmitted to the one-way transmission device corresponding to the routing information, which can be specifically:

[0052] The routing information corresponding to the data file data of the node of the cross-network switching system is updated through the preset routing information in the data routing service deployed on the node of the cross-network switching system; the preset data file set is transmitted to the one-way transmission device corresponding to the updated routing information through the data routing service.

[0053] Step 120: collect own node data through unidirectional transmission equipment, add node information and routing information, generate data file data, add it to the preset data file set, and transmit the preset data file set to the next cross-network switching system node corresponding to the routing information.

[0054] It should be noted that the one-way transmission device has a data routing service function and will also collect information of this node. Similar to step 110, all data are transmitted to the one-way receiving side and transmitted to the data exchange system of the next node through the data routing service corresponding to the one-way transmission device. If there are only two network domains, the data file has reached the end node after passing through the one-way transmission device; if there are multiple network domains, the data routing service will continue to transmit the data file data until the end node.

[0055] Step 130: based on the routing information of the preset transmission link, the data files data of the cross-network switching system nodes and the data files data of the unidirectional transmission devices of each network segment passed during the transmission process are sequentially added to the preset data file set; until the preset data file set is transmitted to the end node of the preset transmission link.

[0056] Among them, the nodes include cross-network switching system nodes and unidirectional transmission equipment.

[0057] It is understandable to those skilled in the art that data files data are collected at the end node, and these data cover the device status, network status, service status, file transfer status, etc. of each node. According to these data, statistical analysis can be performed to obtain the status of the entire data exchange link, the system status of each node, the information of system or file alarms, file loss statistics, etc., so as to diagnose the business situation of the entire cross-network exchange system. For example, for a file with the same unique ID, checking the node to which it is transmitted can determine whether the file is lost. For example, for a file, there is only a record of a single-channel sending module, but no receiving record, then it is determined that the file is lost in the single-channel transmission process.

[0058] Step 140, obtain the preset data file set of the end node through the unified operation and maintenance supervision system; based on the node information, parse and obtain the data file data of each node; then based on the node data in the data file data of each node, obtain the business status and system status of the node; based on the transmission record of the file in the data file data at each node, determine whether the file is lost and the node where the file is lost.

[0059] It should be noted that the node information at least includes device status, network status, program status, data exchange link and file transfer status.

[0060] This step can be specifically as follows:

[0061] By reading the CPU information, memory information, and hard disk information in the device status and comparing them with the preset device status health threshold, it is determined whether the device status of the node is abnormal.

[0062] In some embodiments, the device operating status processing process: Input: read the system-date.n.data file.

[0063] Output: parse out the node name, CPU, memory, and hard disk.

[0065] Memory information: The data file contains the regularly collected memory usage rate, whether the memory usage status is normal, the total memory, the memory usage, and the remaining memory. The recorded data needs to support the display of the memory usage curve in the form of a graph;

[0066] Hard disk information: The data file contains two dimensions: space and inode number. It collects the usage rate of each partition, the total capacity of the hard disk, the usage and the remaining usage. The recorded data needs to support the presentation of the overall usage rate of the hard disk and the usage rate of each partition in the form of a curve or pie chart.

[0067] Read the network port name, network port type, bandwidth, receiving and sending rate, number of bytes received and sent, duplex status, network port load, and network port status in the network status, and display the network status of each network port of the node in the form of a curve graph.

[0068] In some embodiments, the device network status processing process: Input: Read network-date.n.data file.

[0069] Output: each node name, network port name, network port attributes (management port, HA port, service port), network port type (electrical port / optical port), duplex status, bandwidth, number of bytes received and sent, and receive and send rates (kbps or mbps).

[0070] Processing: Display the usage of each network port (send / receive), network port upper limit, etc. in the form of a curve graph. The recorded data needs to support display in the form of a curve graph.

[0071] Read the service name, process ID, CPU usage, memory usage, and operation status in the program status, and present the program status of each service of the node in a list.

[0072] In some embodiments, the program running status processing process: Input: read program-date.n.data file.

[0073] Output: parse out the node name, service programs, process ID, CPU usage, memory usage, operating status (normal / abnormal), and status description. The recorded data needs to be displayed in a table.

[0074] Processing: Supports presenting the running status of each service in a list format, including node name, service name, process ID, CPU usage, memory usage, operating status (normal / abnormal), and status description.

[0075] Read the link channel name, channel status, and status description in the data exchange link, and present the data exchange link data of each link channel of the node in a list.

[0076] In some embodiments, the switch link status process: Input: Read switchlink-date.n.data file.

[0077] Output: parse out the node name, link channel name, channel status, and status description.

[0078] deal with:

[0079] Supports presenting the node name, channel name, channel status, and status description of each channel in a list format. Displays the node name, channel name, channel status, and status description of the channel based on the single-channel heartbeat detection to see if the one-way channel is working properly.

[0080] Read the file transfer status, parse the node name, file ID, file name, processing action, and processing result; obtain the initiating node and receiving node of the file corresponding to the file ID; obtain the file transfer record of the file corresponding to the file ID at the initiating node and the receiving node; wherein the file transfer record includes at least the file name, task ID, file sender, and recipient; when the file transfer records of the initiating node and the receiving node are different, determine that the file corresponding to the file ID is lost.

[0081] In addition, this application can also issue abnormal alarms, which can be specifically:

[0082] When the device status is abnormal, an abnormal device status alarm will be issued; when the program status is abnormal, an abnormal program status alarm will be issued; when the network port load involved in the network status exceeds the threshold or the network port status is abnormal, an abnormal network status alarm will be issued; when there is file loss, a file loss alarm will be issued.

[0083] It should be noted that the alarm reminder can be to display the alarm information on the server interface corresponding to the unified operation and maintenance supervision system.

[0084] Based on the foregoing description, it can be seen that this embodiment, through information collection and data routing, collects data information of multiple nodes in different network domains to one node for analysis, and obtains system monitoring information and file transfer information of all nodes. Through a unified operation and maintenance supervision system, the status of the entire cross-network data exchange system can be viewed intuitively and conveniently, and the business health status can be quickly diagnosed, thereby enhancing the supervision of the cross-network exchange system, improving the efficiency of locating abnormal problems and the speed of problem discovery, and providing a reliable operation and maintenance supervision and business diagnosis solution for products in the field of cross-network data exchange.
