Method For Correcting Time Data In A Network Management Application Using A Snmp
The present invention is directed to a method for correcting time data in a network management application. In a conventional Simple Network Management Protocol (SNMP) application, time errors occur due to a time tick or a time delay in the network. To resolve the above problem, the present invention suggests a method for correcting the time data, wherein the network management application waits for the most polling periods to save system resources, checks time data for the last polling period, and requests performance information and statistic information. With the present invention, the possibility of incurring time errors due to the information request for polling can be resolved.
1 . In a network management application using a Simple Network Management Protocol (SNMP), a method for correcting time data comprising the steps of:
waiting for 90% of a polling period after requesting performance information and statistic information;
checking time data every 500 ms after an elapse of the 90% of the polling period; and
requesting the performance information and statistic information when reaching information requesting time.
