Low-infringement high-efficiency multi-target IP blocking monitoring and scheduling method and system

Abstract

The invention discloses a low-infringement high-efficiency multi-target IP blocking monitoring and scheduling method, which comprises the following steps: establishing two threads which run independently, one thread being a packet sending thread and being used for sending a detection packet and counting a measurement result of each round; the other thread being a packet receiving thread which is only responsible for receiving the response packet and modifying the state of the corresponding equipment in the equipment information array according to the received response packet; packet sending inthe packet sending thread being in a sequential packet sending mode, performing periodic measurement according to measurement intervals; and each round of measurement starting to sequentially send packets to each target device according to a fixed strategy, after packet sending is finished, a packet receiving thread waiting for response timeout of the last packet and uniformly processing the measurement result of the round, if a device state is overturned, reporting the current state of the corresponding device, and otherwise, reporting all device states only when the reporting interval is finished. The method has the obvious advantages of more monitoring targets, less measurement time consumption, less resource occupation, less network infringement, fast blocking discovery and the like.

Description

technical field [0001] The invention belongs to the technical field of network operation and maintenance, and in particular relates to a low-intrusion, high-efficiency multi-target IP blocking monitoring and dispatching method and system. Background technique [0002] In the on-duty maintenance of IP networks, it is usually necessary to quickly discover which devices in the network are blocked (IP unreachable), but it is not possible to generate obvious network burdens for the purpose of monitoring. At present, it is mainly through the method of monitoring the performance of the terminal to discover the blocking situation of the device, that is, when the average forward delay of the performance of the IP terminal of a certain device is -1 or the packet loss rate is 100%, it is considered to be blocked. [0003] There are several ways to find blocking: [0004] Solution 1: Use the ping tool to manually test and find the blockage: This solution manually runs the ping program ...

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
