S610, network element device carries out network performance measurement, obtains the initial data of network performance measurement；
S620, this network element device stores this initial data, in order to Network Management Equipment is real-time from this network element device Obtain this initial data to monitor in real time；Further,
S630, this network element device processes this initial data according to measurement period, stores at according to measurement period Data after reason, in order to this Network Management Equipment obtained from this network element device according to the monitoring cycle should be according to statistics Data after period treatment are to carry out cycle monitoring.
The data acquisition amount of network performance measurement is bigger at present, and data transmission and the expense processed compare Height, affects the efficiency of network performance monitoring.In embodiments of the present invention, network element device is carrying out internetworking Can measure, when obtaining the initial data of network performance measurement, on the one hand, store this initial data, another Aspect, processes this initial data according to measurement period and stores the data after processing according to measurement period；This Sample, Network Management Equipment can according to the monitoring cycle from this network element device obtain this according to measurement period process after Data to carry out cycle monitoring, or, it is original that this Network Management Equipment can obtain this in real time from this network element device Data are to monitor in real time.It is to say, network element device is when carrying out network performance measurement, store two Number evidence, portion is initial data, and another part is the data after network element device processes according to measurement period. Network Management Equipment, when carrying out cycle monitoring, obtains at according to measurement period from network element device according to the monitoring cycle Data after reason, when monitoring in real time, obtain initial data in real time from network element device.
Owing to initial data is first processed by network element device according to measurement period, Network Management Equipment is being carried out During cycle monitoring, the data volume of acquisition reduces, and therefore data transmission and the pressure processed reduce.So, Continual quality of service monitoring can be carried out by cycle monitoring, carry out network actively monitoring, point Analysis network servicequality historical trend, looks back network quality failure cause etc..
On the other hand, for the most identified or suspection business pipeline quality problem, for this business pipeline Can initiate to monitor in real time, in order to frequent obtain up-to-date traffic measurement data.In this case, Network Management Equipment can obtain initial data in real time from network element device, to provide real-time quality of service to client Data, in order to carry out the seizure of accurate trouble point, assist trouble positions.
Therefore, the method for the network performance measurement of the embodiment of the present invention, store internetworking by network element device Can measure initial data and according to measurement period process after data, Network Management Equipment can obtain according to system Meter period treatment after data to carry out cycle monitoring, obtain initial data to monitor in real time, thus Transmitted data amount can be reduced, reduce Network Management Equipment and focus on pressure such that it is able to improve network performance The efficiency measured.
In embodiments of the present invention, alternatively, this network element device stores this initial data, including:
This original data storage is MIB form by this network element device.
Alternatively, this network element device stores the data after processing according to measurement period, including:
Data after this is processed by this network element device according to measurement period are stored as textual form.
Specifically, after network element device records initial data, on the one hand, by this original data storage be MIB form, i.e. SNMP MIB form, do not process.On the other hand, network element device is according to system Initial data is processed by the meter cycle, and the data after processing are stored as textual form, wherein, to former The process that beginning data are carried out can be specifically to be processed initial data, and/or counts initial data Calculate, and/or initial data is carried out statistics etc..So network element device has shared science and engineering at the data of a part Measure, the workload that Network Management Equipment focuses on can be reduced.
The embodiment of the present invention is described in detail below in conjunction with the example shown in Fig. 7.It should be noted that this is intended merely to Those skilled in the art are helped to be more fully understood that the embodiment of the present invention, and the model of the unrestricted embodiment of the present invention Enclose.
As it is shown in fig. 7, network element device 710 carry out network performance measurement obtain measurement data 720, such as, The time delay of cycle generation, packet loss, shake data are measured according to 10 seconds.On the one hand, by measurement data 720 It is stored as MIB form data 721, is supplied to Network Management Equipment 730 by MIB interface.MIB form Data 721 do not process.It is alternatively possible to set the measurement that MIB form data 721 retain The record count of data 720, as at most retained M record (M can be the integer more than 2).Another Aspect, measurement data 720 is processed by network element device 710 according to measurement period, the number after processing According to being stored as textual form data 722, in order to by text interface, such as FTP(File Transfer Protocol, text transfer protocol) interface, it is provided that to Network Management Equipment 730.Such as, according to measurement period Measurement data 720 is processed by (such as 15 minutes), such as the maximum in measurement period, minimum, puts down Averages etc., such network element device 710 can share the data processing work amount of a part.
Network Management Equipment 730, when carrying out cycle monitoring, obtains text according to monitoring cycle (such as 1 hour) Form data 722, it is possible to reduce Network Management Equipment 730 obtains the number of times of measurement data from network element device 710, Also mitigate the process load of Network Management Equipment 730 simultaneously.
When needs monitor in real time, Network Management Equipment 730 obtain in real time (such as, with measure the cycle The cycle of identical 10 seconds obtains) MIB form data 721.So, by cycle monitoring with in real time Monitoring cooperates, and both can obtain lasting long-term result, can obtain again the knot of real-time short-term Really.
Utilize monitoring in real time can initiate on-demand monitoring.It is to say, when cycle monitoring, can be according to Demand, initiates the real-time monitoring with object, measurement on demand.This initiation is one-touch, it is not necessary to extra Configuration, it is not necessary to create task.
