Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to improve the transmission stability, integrity and security of a data stream, the embodiment of the invention provides a data stream transmission control method, a data stream transmission control device, a data stream transmission monitoring device and a computer readable storage medium. Next, first, a description is given of a data stream transmission control method provided by an embodiment of the present invention.
The execution main body of the data stream transmission control method provided by the embodiment of the invention can be monitoring equipment, and the monitoring equipment is added in a data transmission system which currently comprises data transmission equipment such as data generation equipment, data access equipment, data caching equipment, data distribution equipment, data receiving end equipment and the like, and the monitoring equipment controls the transmission process of the data stream. The mode of implementing the data stream transmission control method provided by the embodiment of the invention can be at least one mode of software, a hardware circuit and a logic circuit arranged in the monitoring equipment.
As shown in fig. 1, a data stream transmission control method provided by an embodiment of the present invention may include the following steps:
s101, obtaining data information corresponding to data streams received and transmitted by at least one data transmission device in a data transmission system.
The monitoring device may obtain data information corresponding to the data stream received by at least one data transmission device from data transmission devices such as a data generating device, a data access device, a data cache device, a data distribution device, and a data receiving device in the data transmission system. Specifically, the monitoring device may acquire data information in a real-time monitoring manner, and the monitoring device monitors a transmission process of the data stream between the data transmission devices in real time. In the transmission process of the data stream, each data transmission device receives the data stream in sequence and then sends the data stream, when each data transmission device receives and sends the data stream, the corresponding data information corresponding to the data stream can be obtained, and the data information obtained by monitoring the data transmission device by the monitoring device can include but is not limited to the following contents: data stream transmission signaling, data stream transmission rate (cross-section data), data traffic size (cross-section data), data type, data transmission direction, receiving end device information, connection information, transmission success/failure information, abnormal data stream, and the like. The monitoring device may periodically acquire data information, and in general, may acquire data information corresponding to a data stream received and transmitted by each data device from each data transmission device every 10 seconds.
The monitoring device monitors the data transmission devices by using general data monitoring techniques, such as sokit TCP/UDP (TCP (Transmission Control Protocol, transmission control protocol)/UDP (User Datagram Protocol ) based data packet transmission and reception testing tool), wirereshark (network packet analysis tool), log, and the like. The data stream transmission process of at least one data transmission device in the data transmission system is monitored in real time through the monitoring device, so that the accuracy and the instantaneity of the data stream transmission monitoring are ensured.
S102, analyzing the data information to obtain transmission state information of the data stream.
After the monitoring device obtains the data information corresponding to the data stream received by at least one data transmission device in the data transmission system, the data information is analyzed to obtain the transmission state information of the data stream, for example, by obtaining the data information, it can be known that 10000 pieces of data in total are accessed from the data access device between 9:00 and 10:00, but 9900 pieces of data are cached in the 10:00 data caching device, which means that 100 pieces of data are lost in the process of being transmitted from the data access device to the data caching device, and the transmission state information of the data stream can include the information that 100 pieces of data are lost in the process of being transmitted from the data access device to the data caching device within 9:00 to 10:00 hours. For another example, by acquiring the data information, it can be known that between 9:00 and 10:00 there are 500 pieces of data of type a, 1000 pieces of data of type B and 5000 pieces of data of type C accessed from the data access device, and the transmission status information of the data stream may also include 500 pieces of data of type a, 1000 pieces of data of type B and 5000 pieces of data of type C accessed by the data access device within 9:00 to 10:00 hours.
In summary, the transmission status information of the data stream is the transmission status of each data transmission device in the data transmission system in the process of transmitting the data stream, which may include whether there is data loss, data type, data transmission rate, etc., and the manner of analyzing the data information by the monitoring device may specifically be that data information corresponding to data streams received by different data transmission devices is transversely analyzed, or that data information corresponding to data streams received by the same data transmission device is longitudinally analyzed.
S103, according to the transmission state information, the data stream is subjected to transmission control.
After the monitoring equipment analyzes the transmission state information of the data stream, the transmission processes of the data stream such as flow, data type, data transmission or stop can be controlled according to the transmission state information, the data stream transmission quality is ensured by controlling the data stream transmission, and the data stream transmission risk is prevented. The monitoring equipment is used for controlling the data stream transmission process, so that the data transmission quality can be effectively ensured, and the transmission risk can be controlled.
Optionally, S103 may specifically be: comparing the transmission state information with the transmission state parameters of the standard to determine an abnormal analysis result of the data stream; and carrying out transmission control on the data stream according to the abnormal analysis result.
For the information such as the transmission rate and the packet loss rate contained in the transmission state information of the data stream, the monitoring device is often provided with corresponding reference transmission state parameters, for example, the reference transmission rate is set to be 100kb/s, the packet loss rate is set to be 10%, after the monitoring device analyzes the obtained transmission state information of the data stream, the monitoring device needs to compare the transmission state information with the reference transmission state parameters, and if the transmission rate in the transmission state information is greater than 100kb/s, or the packet loss rate is greater than 10%, the abnormal transmission process of the current data stream is indicated.
Specifically, according to the anomaly analysis result, the step of performing transmission control on the data stream may be: and determining an abnormal event of the data stream and an abnormal grade of the abnormal event according to an abnormal analysis result, judging whether the abnormal grade reaches a preset grade, and if so, alarming the abnormal event and the abnormal grade. When the abnormal transmission process is determined, the abnormal events can be classified, the high-level abnormal events in the current transmission process are alarmed, the specific alarm process can be that the monitoring equipment outputs alarm information, the user is informed of the occurrence of the abnormal events and the abnormal level of the abnormal events, the user is informed of timely processing the abnormal events, and the data is prevented from being tampered. The alarm information can include information about which link has an abnormal event, what type of abnormal event has occurred, the abnormal level of the abnormal event, etc., so that the user can accurately process the abnormal event. For example, by comparing the transmission state information with the reference transmission state parameters, an abnormal analysis result with the packet loss rate of 80% is obtained, and a high-level packet loss event with the packet loss rate of more than 60% is predefined, so that the high-level packet loss event of the current data stream can be determined, and therefore, the monitoring device can initiate alarm information to the user to inform the user that the high-level packet loss event occurs so as to prompt the user to process the abnormal event.
Optionally, S103 may specifically be: identifying the data type of each data in the data stream according to the transmission state information; and carrying out transmission control on each data in the data stream according to the data type of each data.
The transmission state information comprises data types of data, and the monitoring equipment can identify the data types of all the data in the data stream after analyzing the transmission state information, and can perform transmission control according to the data types of all the data when the transmission control of the data stream is performed.
Optionally, the step of performing transmission control on each data in the data stream according to the data type of each data may specifically be: and if the data type of each data comprises the risk type, controlling at least one data transmission device in the data transmission system to stop transmitting the data of the risk type.
The monitoring device may be provided with a transmission start-stop control, if the monitoring device identifies that the data type of each data includes a risk type, the risk type data may bring risks to the whole data transmission system, for example, flood type data, and if the risk type data exists, blocking processing should be immediately adopted, so that the data transmission device is controlled to stop transmitting the risk type data. The specific way to control the data transmission device to stop transmitting the risk type data may be: the monitoring equipment issues a transmission stopping instruction to each data transmission equipment, the transmission stopping instruction carries a risk type, each data transmission equipment analyzes the risk type after receiving the transmission stopping instruction, and then the data transmission stopping of the risk type in the data stream is identified according to the risk type.
Optionally, the step of performing transmission control on each data in the data stream according to the data type of each data may specifically be: and if the data type of each data comprises the specified permission type, controlling at least one data transmission device to transmit the data of the specified permission type, and controlling at least one data transmission device to block the data which is not of the specified permission type.
The monitoring device may be further provided with a transmission type control, and if the monitoring device recognizes that the data type of each data includes a specified permission type, for example, the specified permission type is set to A, B, and recognizes that the data stream includes data of data type a, data of data type B, and data of data type C, the monitoring device controls each data transmission device to transmit data of data type a and data type B, and blocks data of data type C. By filtering and screening the data stream, the specified data with the preset permission type can be freely transmitted. The specific manner of controlling the data transmission device to transmit the data with the data type being the preset permission type may be: the monitoring equipment issues a transmission control instruction to each data transmission equipment, the transmission control instruction carries a data type of data which is allowed to be transmitted, each data transmission equipment analyzes the data type of the data which is allowed to be transmitted from the transmission control instruction after receiving the transmission control instruction, and only the data with the data type is transmitted according to the data type, so that the data with other data types are blocked. Wherein the data other than the specified permission type may include data of a risk type and data of a non-risk type.
Optionally, S103 may specifically be: acquiring the transmission channel flow of at least one data transmission device; and controlling the flow rate of the data flow transmitted by at least one data transmission device to be smaller than or equal to the flow rate of the transmission channel.
The monitoring device can also be provided with transmission flow control, the transmission channel flow of at least one data transmission device is obtained, the flow of the data flow transmitted by the at least one data transmission device is controlled to be smaller than or equal to the transmission channel flow, and the data transmission stability is kept by controlling the data transmission flow. The transmission channel flow is the maximum channel flow of the data stream which can be transmitted by the channel for transmitting the data stream, and the data transmission flow is controlled so that the data transmission flow is smaller than or equal to the transmission channel flow, so that the normal transmission of the data stream by the transmission channel can be ensured. The specific way of controlling the data transmission device to transmit the data stream with the flow rate smaller than or equal to the flow rate of the transmission channel may be: the monitoring equipment issues transmission control instructions to each data transmission equipment, the transmission control instructions carry preset flow (the preset flow is smaller than or equal to the flow of a transmission channel), after each data transmission equipment receives the transmission control instructions, the preset flow is analyzed from the data transmission equipment, and the maximum flow of the transmission data flow is set according to the preset flow.
Optionally, S103 may specifically be: acquiring service state information of at least one data transmission device; and carrying out transmission control on the data stream according to the transmission state information and the service state information.
The monitoring device may acquire service state information of the data transmission device in addition to data information corresponding to the data stream received by each data transmission device, and specifically, the service state information may be acquired by monitoring in real time, and may acquire service state information according to a preset period, for example, may acquire service state information every 30 seconds. Service state information includes, but is not limited to: service processes/threads, resource overhead status (CPU, memory, network, disk, etc.), cache status, software service running status, etc. The monitoring device may acquire service status information by using a general data monitoring technology, such as zabbix (a distributed system monitoring scheme), nagios (an open-source free network monitoring tool), zenoss (an open-source network management software tool), and so on.
Aiming at the acquired service state information, the service state information can be analyzed, and particularly, the traditional service state analysis mode can be adopted for analysis, so that the running state of each service is analyzed, and the risk is timely identified. At this time, the monitoring device may perform transmission control on the data stream in combination with the transmission state information and the service state information.
Optionally, the step of performing transmission control on the data stream according to the transmission state information and the service state information may specifically be: determining the data quantity of the current data flow according to the transmission state information; determining the residual data buffer space of at least one data transmission device according to the service state information; setting a threshold for the remaining data buffer space of the at least one data transmission device, wherein the threshold is less than or equal to the remaining data buffer space of the at least one data transmission device; judging whether the data quantity of the current data flow is larger than a threshold value or not; and if the data quantity of the current data stream is larger than the threshold value, reducing the transmission speed of at least one data transmission device to the current data stream.
The monitoring device may be provided with a data buffer control, and the transmission status information includes a data amount of the data stream, so that the data amount of the current data stream may be determined, and the service status information includes the buffer status information, so that a remaining data buffer space of each data transmission device may be determined. The remaining data buffer space defines how much data can be buffered at most, if the amount of data to be buffered exceeds the capacity of the remaining data buffer space or is close to the capacity of the remaining data buffer space, a great challenge may be brought to the buffering task, and therefore, a threshold value smaller than or equal to the remaining data buffer space may be set based on the remaining data buffer space of each data transmission device. If the data volume of the current data stream is larger and the residual data buffer space of each data transmission device is insufficient, that is, if the data stream of the current data stream is larger than the threshold value, the data stream to be buffered exceeds or approaches to the capacity of the residual data buffer space, the data transmission device can be controlled to reduce the transmission speed of the current data stream, that is, the data access speed is controlled or the data forwarding speed is adjusted, so that the data stream does not quickly occupy the residual data buffer space of the data transmission device.
The specific way to reduce the transmission speed of the data transmission device to the current data stream may be: the monitoring equipment sends a speed control instruction to each data transmission equipment, the speed control instruction carries a specific value of the transmission speed, after receiving the speed control instruction, the monitoring equipment analyzes the transmission speed from the speed control instruction, and accordingly adjusts the transmission speed of the current transmission data stream.
In the data transmission process, the real-time data can be transmitted preferentially, and when the historical data needs to be retransmitted and the like, the historical data can be processed after the real-time data is transmitted.
By applying the embodiment, the monitoring device obtains data information corresponding to the data stream received and transmitted by at least one data transmission device in the data transmission system, analyzes the data information to obtain transmission state information of the data stream, and performs transmission control on the data stream according to the transmission state information. In a traditional data transmission system formed by a plurality of data transmission devices, a monitoring device is added, data information corresponding to data streams received and transmitted by at least one data transmission device is obtained through the monitoring device, the data stream transmission state information is obtained through analysis, the data stream transmission state information can reflect the data stream transmission state, and the data stream can be timely transmitted and controlled based on the transmission state information, so that the data stream transmission stability is improved. Because different transmission control strategies can be selected for transmission control according to different transmission states, risks in the data stream transmission process can be effectively prevented and controlled, and the integrity and safety of data transmission are improved. By the method, the state of the data transmission system can be perceived in real time, and the control of the transmission direction, what data is transmitted, the size of the transmitted data quantity, which data is transmitted to who, which data is not transmitted to who and the like is realized through data stream transmission control, so that the data transmission is more accurate. The embodiment of the invention solves the problem of lack of control in the data transmission process, ensures the data transmission quality and prevents the data transmission risk.
