A low intrusion efficient multi-target IP blocking monitoring scheduling method and system

Abstract

The invention discloses a low-intrusion, high-efficiency, multi-target IP blocking monitoring and dispatching method. Two independently running threads are established, one is a packet sending thread, which is responsible for sending detection packets and counting the results of each round of measurement; the other is a receiving thread The packet thread is only responsible for receiving response packets, and modifies the status of the corresponding devices in the device information array according to the received response packets; the packet sending in the packet sending thread is a sequential packet sending mode, and periodic measurement is performed according to the measurement interval, and each round of measurement starts according to a fixed strategy in order Send a packet to each target device. After the packet is sent, the packet receiving thread waits for the response of the last packet to time out, and processes the measurement results of this round uniformly. If the state of any device has been reversed, report the current state of the corresponding device, otherwise it will only end at the end of the reporting interval. All device status is reported on time. The present invention has the obvious advantages of many monitoring targets, less time-consuming measurement, less resource occupation, less network intrusion, and fast blocking discovery.

Description

technical field [0001] The invention belongs to the technical field of network operation and maintenance, and in particular relates to a low-intrusion and high-efficiency multi-target IP blocking monitoring and scheduling method and system. Background technique [0002] In the on-duty maintenance work of the IP network, it is usually necessary to quickly find out which devices in the network are blocked (IP unreachable), but it cannot generate obvious network burden for the purpose of monitoring. At present, device blocking is mainly detected by monitoring the performance of the terminal. That is, when the average performance delay of the IP terminal of a device is -1 or the packet loss rate is 100%, it is regarded as blocking. [0003] There are several ways to find blocking: [0004] Option 1: Manual testing with ping tool to find blocking: In this solution, the target is tested by manually running the ping program that comes with the operating system, for example: [00...

AI Technical Summary

Problems solved by technology

[0007] Significant disadvantages of this scheme: (1) manual operation, low efficiency, not conducive to monitoring multiple targets

(2) The result data is difficult to effectively use, and cannot be directly stored, displayed, and statistically analyzed

[0009] This scheme has the following disadvantages: (1) The monitoring function is not targeted

(2) Each round of measurement takes more time

(3) Take up a lot of resources

(4) There is a lot of network intrusion traffic

(5) - The storage of measurement results takes up a lot of resources

Because the terminal performance obtained by each measurement needs to be stored, if the measurement results need to be transmitted, the transmission traffic and complexity will also be increased

(6) The detection of blocking is not timely

In order to reduce the intrusion on the network, the measurement interval is generally increased (for example, set to x minutes). In the case of high immediacy requirements (x seconds) for blocking alarms, this method cannot meet the requirements

(7) Inaccurate judgment of continuous blocking or discrete blocking

Because the measurement period is long, the separation value for distinguishing two consecutive alarms is greater than the measurement interval, which is not conducive to accurate division
