The interior ethernet port of interval T computing time sends the byte number of data, calculate the current outlet bandwidth (being the speed of current transmission data) that takies ethernet port by the byte number that sends data, further calculate current ethernet port outlet bandwidth take ratio.
Further, device of the present invention can also comprise memory module and drawing module, wherein,
Memory module, be used to store described calculating constituent parts time ethernet side port band width take ratio;
The drawing module according to the ratio that takies of the constituent parts time ethernet side port band width of described memory module storage, is drawn the historical situation figure that takies ratio of ethernet side port band width.
Device of the present invention can take ratio with current bandwidth and deposit history in, draw the condition diagram of the ethernet port bandwidth occupancy ratio of each time point according to history value, port bandwidth described here take than condition diagram with can with the statistics time be abscissa, ethernet port takies than being the curve image of ordinate or bar image.
Further, device of the present invention can also comprise display module, be used to show the ratio that takies of described ethernet side port band width, can show the condition diagram of described ethernet port bandwidth occupancy ratio, take ratio with inlet bandwidth occupancy ratio and the outlet bandwidth that offers the current ethernet port of user.
Monitoring module of the present invention also can be used for detecting in real time the situation about taking of ethernet side port band width, reaches default threshold value if detect the ratio that takies of described ethernet side port band width, then triggers predetermined business, for example switching services etc.
Fig. 2 is the flow chart of the method for real-time monitoring ethernet side port band width of the present invention, as shown in Figure 2, comprises following step:
S10, gather the byte number of ethernet port transmission data periodically;
S20, calculate the ratio that takies of ethernet side port band width in real time according to the byte number of described collection.
Wherein, in step S10, be responsible for obtaining of original transmitted byte number, need the current port of output to receive byte number and transmission byte number by above-mentioned acquisition module.This collecting work circulation is carried out.
The port band width of going into real-time monitoring ethernet port is that example describes below, and the method for the outlet bandwidth of monitoring ethernet port is similar with the method for going into port band width of monitoring ethernet port, here just no longer repeat specification:
Suppose that t1 constantly, enables the device of real-time monitoring ethernet side port band width of the present invention, it is T second that acquisition interval is set.Device of the present invention distributes one to gather storage space S 1 and S2, to the reception byte number n1 of S1 assignment ethernet port 1; Then, enable timing program, timing T is after the time arrives, to the reception byte number n2 of S2 assignment ethernet port 1; N1 and three parameters of n2, T are passed to monitoring module.
Step S20 can comprise following step, as shown in Figure 3:
S201, monitoring module receive three parameters such as byte number n1, n2 and time interval T;
S202, from the ethernet port configuration information, read the band width in physical B of ethernet port 1;
S203, calculating t2 be the current inlet rate b1 of ethernet port 1 constantly, b1=(n2-n1)/T;
S204, computation bandwidth take percentage p1=b1/B*100%, and p1 is passed to display module.
Further, display module is received after the p1 parameter, shows the current inlet rate of ethernet port 1 and takies ratio to the user.
Further, can memory allocated unit H, the p1 value is composed to history storage unit H[1] [1].The drawing module is according to H[1] [1] value draws out the position on curve chart in t2 moment, as shown in Figure 4.
According to the present invention, all ethernet ports all can be enabled port bandwidth of the present invention and monitor in real time on the equipment, and the monitoring of each port is separate, is independent of each other.
In the application facet of monitored results, can be for the user according to the bandwidth usage of each port on the monitored device, further rationally reliable planning network resource.The port traffic that is in saturation condition for a long time can be shared on other idle relatively device ports, perhaps to this generic port configuration protection.On the low side always for the port bandwidth occupancy, even be 0 port for a long time, the user can in time analyze reason, and such as whether this part port resource is in idle state always, whether this part port resource corresponding service is cancelled.The user can in time integrate existing idle port, puts in the new planning to make full use of existing resources.
In the application facet of monitored results, can the trigger condition of the bandwidth occupancy ratio of ethernet port as intended service (for example, miscellaneous services such as business, alarm, utilization rate of equipment and installations statistics are switched in protection) will be monitored in real time to equipment vendors.All can use in client's side and system side.For example; applying to protection switches in the business: the bandwidth usage threshold value that ethernet port can be set; trigger (partly or entirely) switching services when current ethernet port bandwidth usage surpasses threshold value, can alleviate like this by burst service and cause port to carry the saturated and loss of traffic that causes of transition.
One of ordinary skill in the art will appreciate that all or part of step in the said method can instruct related hardware to finish by program, described program can be stored in the computer-readable recording medium, as read-only memory, disk or CD etc.Alternatively, all or part of step of the foregoing description also can use one or more integrated circuits to realize.Correspondingly, each the module/unit in the foregoing description can adopt the form of hardware to realize, also can adopt the form of software function module to realize.The present invention is not restricted to the combination of the hardware and software of any particular form.
Below only be the preferred embodiments of the present invention; certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
