Description

Technical Field

[0001] The invention belongs to the technical field of network management data collection systems, and in particular relates to a polling implementation method for network management data collection systems. Background Art

[0002] The ‌Network Management Data Collection System‌ is a data collection system used for network management, mainly used to monitor and manage various devices and resources in the network. It helps network administrators better understand the status of the network by collecting and analyzing data in the network, timely discover and solve potential problems, and ensure the stable operation of the network.

[0003] In the prior art, when the network management data collection system is collecting data, during the polling process, even if a task or process has no new request, it still needs to be polled and accessed in sequence, wasting some system resources. When the number of tasks or processes is large, polling takes a long time to traverse, affecting the operating efficiency of the system. In some cases, frequent polling will put pressure on the server and affect the stability of the system.

[0004] Therefore, it is necessary to invent a polling implementation method for a network management data collection system to solve the above problems, which can dynamically adjust the polling interval according to the network congestion situation to reduce network congestion and improve data receiving efficiency. Summary of the invention

[0005] In view of the above problems, the present invention provides a polling implementation method for a network management data collection system to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: a polling implementation method of a network management data collection system, including a polling implementation method of a network management data collection system, the method is as follows: Step 1: Get resource information of each modem of the communication server: The network management end first needs to get the status and configuration resource information of each modem of the communication server; Step 2, "assigning polling commands": according to the acquired resource information, the polling commands are assigned to the authentication queue and the non-authentication queue respectively according to whether the authentication number of the corresponding device corresponds to the dial-up number of the modem; Step 3. Set the timer: Use the setTimeout function to set the timer, trigger events at fixed time intervals, and then perform polling after each time interval. Step 4: Determine the device status: In each transmission cycle, the network management end needs to determine the status of each modem and send corresponding polling commands according to the status; Step 5. Dynamically adjust the polling interval: Dynamically adjust the polling interval according to network congestion to reduce network congestion and improve data reception efficiency; Step 6: Use weighted round-robin scheduling algorithm: By obtaining the ARP table information of network devices for analysis and comparison, dynamically adjust the polling weight of the device to adapt to changes in the network structure; Step 7. Polling ends: When all modems have completed sending the polling commands, this round of sending cycle ends.

[0007] Preferably, the setTimeout function is a built-in function in JavaScript, which is used to execute a function or calculation expression after a specified number of milliseconds. It allows developers to execute code after a specified delay time and is an important tool for implementing asynchronous logic and time control.

[0008] Preferably, in step five, network congestion may cause an increase in data packet transmission delay, and the network delay may be determined by checking the RTT of the data packet.

[0009] Preferably, the RTT is Round-Trip Time, i.e., round-trip time. In a computer network, it is the total time from when the sender sends data to when the sender receives confirmation from the receiver, i.e., the receiver sends confirmation immediately after receiving the data. RTT is one of the important indicators for measuring network performance, and ms is used as the unit of measurement.

[0010] Preferably, in step five, the polling interval is dynamically adjusted according to network congestion conditions.

[0011] Preferably, the weighted round-robin scheduling algorithm is a load balancing algorithm used to distribute requests to multiple servers, each server accepts a corresponding number of requests according to its weight. The main purpose of the weighted round-robin scheduling algorithm is to solve the problem of different performance between servers. The processing performance of the server is represented by the weight, and requests are distributed to each server according to the weight and polling method.

[0012] Technical effects and advantages of the present invention: 1. When the network management data collection system of the present invention performs data collection, the polling algorithm can fairly allocate resources among multiple tasks or processes to ensure that each task has a chance to be processed, avoid the situation where certain tasks or processes are ignored for a long time, and can dynamically allocate requests according to the processing capacity of the server to ensure load balancing; when the number of tasks or processes is large, network congestion will cause increased data packet transmission delay. The network delay is judged by checking the RTT of the data packet, and the polling interval is dynamically adjusted according to the network congestion to reduce network congestion and improve data receiving efficiency.

[0013] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention.

The main purpose of the weighted round-robin scheduling algorithm is to solve the problem of different performances among servers. The processing performance of the server is represented by the weight, and requests are distributed to each server according to the weight and the polling method. The scheduling logic is added to the scheduler class to calculate the total weight, and then the requests are distributed in order according to the weight.
