Method for polling communication device by network management system

Abstract

A method for polling communication devices by a network management system. The network management system and the communication device are respectively set with modified data time stamps, and the network management system regularly reads the modified data time stamps of the communication devices, which are compared with the time of modified data saved by itself. If it is found to be equal, no other data will be read; if it is not equal, the time stamp of the modified data saved by itself will be updated, and the data of the communication device will be read and stored in the database. At the same time, the network management system also reads and operates in combination with reading data flags, reading all data flags, and modifying the data index cache, which can reduce the number of times the network management system reads data in polling, thereby reducing network traffic and network load; at the same time Reduce the processing load of the network management system, so that the network management system can manage more devices.

Description

technical field [0001] The invention relates to the technical field of network management, in particular to a method for a network management system to poll communication equipment. Background technique [0002] Today's networks must be able to support a new generation of high-bandwidth applications, wireless links and ever-increasing database storage capacity. At the same time, once the network fails or the operating status is not good, the data flow will be blocked, and key data cannot be effectively shared, resulting in a decline in operational efficiency, which affects the production efficiency and work efficiency of all walks of life, resulting in huge losses. Therefore, network management is also facing increasing pressure, and the importance of network management is becoming more and more apparent. Collecting data from managed devices generally adopts the polling-only method, that is, periodically fetching data from devices to NMS (Network Management System, that is,...

AI Technical Summary

Problems solved by technology

[0011] The disadvantage of the existing technology is that during the polling process of the NMS, although many data on the device have not changed, the NMS has to fetch them one by one for comparison, which not only makes the polling process longer and increases the network burden, but also increases the network load on the NMS. The comparison is performed every time, which increases the processing burden of the NMS
