Abstract
The invention provides a method and a device for measuring bandwidth, wherein the method comprises the following steps: step S1, initializing a line bandwidth value as a bandwidth default value; step S2, periodically detecting the interface flow rate and recording the peak value of the interface flow rate, wherein the peak value of the interface flow rate is the maximum value of the interface flow rate detected from the initialization to the current moment; and step S3, adjusting the line bandwidth value according to the bandwidth default value, the current line bandwidth value and the peak value of the interface flow rate. The method records the maximum value of the interface flow rate detected from the initialization to the current moment, namely the peak value of the interface flow rate, and adjusts the line bandwidth value according to the bandwidth default value, the current line bandwidth value and the peak value of the interface flow rate, thus the adjustment of the line bandwidth does not independently depend on the peak value of the interface flow rate so as to avoid the problem that the actual bandwidth of a line cannot be characterized correctly because the bandwidth control is turned on so that the interface flow is suppressed.
Description
Technical field
The present invention relates to a kind of bandwidth measurement method and apparatus, particularly relate to the method and apparatus of network line Bandwidth Dynamic measuring technique, belong to data communication technology field.
Background technology
The network bandwidth is meant the maximum amount of data that can transmit in the unit interval, it is a unit with bits per second (bits per second, be called for short bps) usually, i.e. the per second bit number that can transmit.
Broadband communication network is to be provided by Internet Service Provider's (Internet Service Provider is called for short ISP), and is interconnected to allow each user terminal and local area network (LAN) to communicate.In existing broadband communication network, when user terminal or enterprise, Internet bar's local area network (LAN) etc. enter the Internet, need and buy bandwidth and access way to the ISP application, described access way generally comprises: Asymmetrical Digital Subscriber Line (Asymmetric Digital Subscriber Line is called for short ADSL), optical fiber exclusively enjoy access or the like.Personal user's terminal generally inserts by ADSL, and enterprise, Internet bar's local area network (LAN) generally adopt optical fiber to exclusively enjoy access way.
Fast development along with network technology, various network applications emerge in an endless stream, and the network bandwidth is constantly proposed more, higher demand, particularly point-to-point (Peer to Peer, that abbreviation P2P) uses enriches constantly, makes network bandwidth resources more and more seem deficient.
For limited bandwidth resources reasonably being controlled and being distributed, guarantee the fairness of allocated bandwidth and the normal operation that guarantees key business, the network equipment now (as: router, switch etc.) has all carried network bandwidth controlled function, these bandwidth controlled function often need to know in advance the line bandwidth of local area network (LAN) and the Internet wired, and then just can carry out rational allocated bandwidth.If the line bandwidth of precognition is inaccurate, then just may influence the reasonability of allocated bandwidth.Suppose that the circuit actual bandwidth can only reach 6 MBPSs (Mega bits per second, be called for short Mbps), but the bandwidth controlled function is but distributed by the 10Mbps bandwidth of precognition, possible some time etching system distributes the bandwidth of 7Mbps to high-priority service, and distribute the 3Mbps bandwidth to low priority traffice, but because circuit actual bandwidth 6Mbps only, the 7Mbps bandwidth of high-priority service can't guarantee at all.Suppose that the circuit actual bandwidth has 10Mbps, but the bandwidth controlled function but distribute by the 8Mbps of precognition, the bandwidth that so just has a 2Mbps can not get distributing all the time, influences bandwidth availability ratio.That is to say,, allocated bandwidth is fallen flat if the bandwidth value of precognition does not conform to the actual conditions, even complete failure.
Yet most users do not have corresponding network context knowledge, so the general network equipment can only require the user to import the line bandwidth value that ISP provides.But owing to subjective and objective reasons such as line losses, the maximum of enterprise, Internet bar's local area network (LAN) etc. and internet communication can reach bandwidth value and often be lower than the bandwidth value that it is bought from ISP, so the network equipment generally also needs built-in line bandwidth measuring ability, so that allocated bandwidth has more reasonability.
Existing bandwidth measurement method can be set a bandwidth default value, and as initial bandwidth higher limit, automatically passing through to add up network equipment institute data packets for transmission flow in time rating in the testing process, estimate network bandwidth value, if the estimation bandwidth value surpasses the bandwidth higher limit, then with estimating the more bandwidth higher limit of the original record of new network device of bandwidth value.This bandwidth measurement method detects by Infinite Cyclic, is higher than the bandwidth higher limit as long as the current transmission bandwidth value occurs, then upgrades the bandwidth higher limit.
Though this technical scheme realizes simple, but have the following disadvantages: this scheme does not consider whether open bandwidth control during line bandwidth is measured, if open bandwidth control when initial, because bandwidth control can influence the utilance of line bandwidth, then interface flow can accurately not characterize the circuit actual bandwidth because suppressed, and this scheme is only upgraded line bandwidth according to current bandwidth measurement situation, thereby can't measure bandwidth value accurately; If do not open bandwidth control when initial, open again through all after dates of a bandwidth measurement, may cause unstable networks when then initial.Therefore this scheme can't be when opening the bandwidth controlled function actual bandwidth of accurate Measurement Network circuit.

Embodiment
Below in conjunction with accompanying drawing the present invention is carried out specific description.
Fig. 1 has provided a kind of bandwidth measurement method of the present invention embodiment one schematic diagram, said method comprising the steps of:
Step S1, the initialization line bandwidth value is a bandwidth default value;
Described bandwidth default value can be the bandwidth value that ISP provides, or the line bandwidth value estimated of user oneself, the approaching more reality of this discreet value in theory, and system just can more early detect bandwidth value accurately.
Step S2 regularly detects interface flow speed, and record interface flow rate peak value; Described interface flow speed peak value is from initial detected interface flow speed maximum till the current time;
Interface flow speed statistics is as follows: the data total flow that the system statistics interface received in a time rating, then with statistical value divided by time rating, promptly obtain current interface flow speed.Compare current interface flow speed and interface flow speed peak value, if current interface flow speed greater than interface flow speed peak value, then updating interface flow rate peak value is the present flow rate rate value.
In the interface flow speed statistics, time rating is too short, and the bursty data of interface may influence the speed statistical accuracy; Time rating is oversize, and then the real-time variation of speed statistics influences the speed statistical accuracy equally, can suitably adjust the length of time rating when specifically implementing according to actual conditions, general time rating value be 5 seconds proper.
Step S3 adjusts line bandwidth value according to bandwidth default value, current line bandwidth value and interface flow speed peak value.

Whether step S31 judges described interface flow speed peak value greater than current line bandwidth value, if then adjust line bandwidth value according to bandwidth default value and interface flow speed peak value, otherwise execution in step S32;
Describedly adjust line bandwidth value according to bandwidth default value and interface flow speed peak value two kinds of execution modes can be arranged: a kind ofly be, do not allow line bandwidth value to be higher than bandwidth default value, then this moment line bandwidth value is adjusted into bandwidth default value, if network environment has a strict demand to congested, then measure for accurate line bandwidth more and will help avoiding congested more, thisly would rather sacrifice certain line bandwidth resource, can not allow the line bandwidth measured value be higher than the conservative mode of circuit actual bandwidth, can better avoid congested to a certain extent; Another kind is, allow line bandwidth value to be higher than bandwidth default value, then at this moment, line bandwidth value can be adjusted into interface flow speed peak value or interface flow speed peak value is added a preset value, this mode is mainly used in does not have too high request to network congestion, and wish to improve as far as possible the environment of line bandwidth utilance, adopting the flow rate peak value to add a preset value mainly is in order to improve the line bandwidth utilance, but preset value can not be too big, otherwise may influence the accuracy that line bandwidth is measured.
Step S32 when system operation time reaches the cycle very first time, adjusts line bandwidth value according to current line bandwidth value and interface flow speed peak value.
At system's run duration, per running time, period T 1, and promptly compliance with system reaches the cycle very first time running time.When circuit actual bandwidth during less than bandwidth default value, adjust and will occur in first cycle of operation T1 the first time of line bandwidth value, line bandwidth value will equal bandwidth default value always before this, so value principle of period T 1: at T1 in the cycle, line bandwidth bandwidth availability ratio occurs and reaches 100% probability greater than more than 50%, the value of T1 can not be too big, otherwise can influence ageing that bandwidth adjusts, when specifically implementing generally T1 be set to one day.During concrete the adjustment, can adjust line bandwidth value and be certain value between interface flow speed peak value and current line bandwidth value, for example line bandwidth is adjusted into half of interface flow speed peak value and current line bandwidth value sum.

Step S312 adjusts line bandwidth value according to bandwidth default value or interface flow speed peak value; Describedly adjust line bandwidth value according to bandwidth default value or interface flow speed peak value and be specifically as follows: line bandwidth value is adjusted into bandwidth default value, or line bandwidth value is adjusted into interface flow speed peak value, or line bandwidth value is adjusted into interface flow speed peak value adds second increment size that sets in advance.
Step S313 heightens line bandwidth value; The described line bandwidth value of heightening is specifically as follows simply with first increment size that sets in advance of current line bandwidth value increase.
Fig. 4 has provided a kind of bandwidth measurement method of the present invention embodiment four schematic diagrames, and present embodiment also comprises except the step that comprises method embodiment two:
Regularly detect after the interface flow speed described in the step S2, also comprise N value of record interface flow rate maximum, wherein N is the value of setting in advance.Be specifically as follows: with N value of interface flow speed maximum and current interface flow speed ratio, if current interface flow speed is then replaced this minimum value with current interface flow speed greater than the minimum value in this N the value.Wherein, the general value of N is 20 to get final product, and the value of N can be done suitable adjustment according to actual conditions when specifically implementing.
Present embodiment also comprises before the execution in step S32 described in the step S31: execution in step S33: judge whether system operation time reached for second time cycle, if then adjust line bandwidth value, otherwise execution in step S32 according to N the value and the current line bandwidth value of interface flow speed maximum.
At system's run duration, per running time, period T 2, promptly satisfied system operation time and reached for second time cycle.The principle of T2 value: at T2 in the cycle, the interface circuit bandwidth bandwidth availability ratio occurs and reaches 100% probability above more than 90%, so the T2 value is big more, the accuracy of measurement is just high more, but just reduced with the ageing of Time Bandwidth adjustment, it is proper that generally T2 is set to a week.
Described N value and current line bandwidth value according to interface flow speed maximum adjusted line bandwidth value and be specifically as follows: whether the difference of judging maximum and minimum value in N the value of described interface flow speed maximum is above the difference threshold that sets in advance, if then adjust line bandwidth value, otherwise line bandwidth value is adjusted into interface flow speed peak value according to interface flow speed peak value and current line bandwidth value.
In fact maximum is interface flow speed peak value in N the value of described interface flow speed maximum.
Present embodiment can also carry out above-mentioned expansion except carrying out the above-mentioned expansion on the basis of method embodiment three on the basis of method embodiment two.
Fig. 5 has provided a kind of bandwidth measurement method of the present invention embodiment five schematic diagrames, and present embodiment also comprises step S4 except the step that comprises method embodiment four: upgrade bandwidth adjusted value sequence, execution in step S2 according to the adjustment situation of current line bandwidth value.

The method of described renewal bandwidth adjusted value sequence can for: record is more than or equal to the bandwidth adjusted value of interface flow speed peak value, and with described sequence sequence arrangement by size in bandwidth adjusted value sequence.During initialization, bandwidth adjusted value sequence is bandwidth default value.
Heightening line bandwidth value described in the step S313 is specifically as follows: heighten line bandwidth value according to interface flow speed peak value and bandwidth adjusted value sequence, for example can from bandwidth adjusted value sequence, find out the most approachingly and greater than the bandwidth adjusted value of described peak value, adjust line bandwidth value and be a value between this value and interface flow speed peak value with interface flow speed peak value.The described line bandwidth value of heightening also can be adjusted into line bandwidth value current first increment size that sets in advance of line bandwidth value increase;
According to after bandwidth default value or the interface flow speed peak value adjustment line bandwidth value, also comprise execution in step S4 described in the step S312;
Heighten described in the step S313 after the line bandwidth value, also comprise execution in step S4;
According to after current line bandwidth value and the interface flow speed peak value adjustment line bandwidth value, also comprise execution in step S4 described in the step S32;
According to after N of interface flow speed maximum value and the current line bandwidth value adjustment line bandwidth value, also comprise execution in step S4 described in the step S33.
In addition, in step S32, when judging that system operation time does not reach the cycle very first time, execution in step S2.
Fig. 6 is a kind of bandwidth measurement method of the present invention embodiment six schematic diagrames.
In the present embodiment, bandwidth default value is initialized as the bandwidth value that ISP provides, and when the line bandwidth value of coming out when detection of dynamic is higher than the bandwidth value that ISP provides, provides bandwidth value to be as the criterion with ISP, and promptly whenever line bandwidth value is not higher than the bandwidth value that ISP provides.Because in the actual application environment, when the ISP network was comparatively idle, the network line bandwidth may be higher than the bandwidth value that ISP provides, but when the online peak period, the bandwidth of network line more may be lower than the ISP value of providing usually.In order to make the line bandwidth value of measuring at any time can both obtain good performance, we are more prone to the value of keeping of going bail for.
Suppose that the interface flow peak value is F, the bandwidth value that ISP provides is Bc, and current line bandwidth value is B, below in conjunction with Fig. 6 present embodiment is elaborated:
Step 201 is initialized as the bandwidth value Bc that ISP provides with line bandwidth value B.
Step 202, be taken as 5 seconds the time rating of interface flow speed statistics, calculated current interface flow speed in per 5 seconds, and record interface flow rate peak F and interface flow speed preceding 20.
Whether step 203 judges the interface flow peak F greater than current line bandwidth value B, if execution in step 204 then, otherwise execution in step 208.
Step 204 is judged the bandwidth value Bc whether the interface flow peak F provides greater than ISP, if execution in step 207 then, otherwise execution in step 205.
Step 205 is found out in the bandwidth adjusted value sequence, and is the most approaching and greater than the bandwidth adjusted value Bf of F with F.Suppose that bandwidth adjusted value sequence is for (8.5Mbps), if this moment, the interface flow peak F was 8.6Mbps, then Bf is 9Mbps for 10Mbps, 9Mbps.
Step 206, adjusting line bandwidth B is (Bf+F)/2.In step 205 example, it is 8.8Mbps that adjustment back line bandwidth value equals (9+8.6)/2.
Step 207 is adjusted line bandwidth B for the bandwidth value Bc that ISP provides, and withdraws from the bandwidth detection flow process.Owing to when interface flow speed peak F surpasses pre-set bandwidths Bc, still line bandwidth B is set at Bc among this embodiment, thereby still can repeats this process after the follow-up judgement flow process arrival step 202, thereby directly finish this flow process in the present embodiment.
Step 208 judges whether system's cycle of operation reach a week, if execution in step 209 then, otherwise execution in step 212.After system moves 7 days for the first time, can meet this judgement, move after 14 days, also meet this judgement, the rest may be inferred.
Step 209 judges whether maximum and minimum value differ provides 1% of bandwidth value Bc greater than ISP among preceding 20 of interface flow speed.If, preceding 20 that then show the interface flow rate value is very approaching, therefore interface flow speed peak F can characterize circuit actual bandwidth value preferably, execution in step 211, otherwise, expression interface flow speed preceding 20 sudden stronger, so interface flow speed peak F can not well characterize circuit actual bandwidth value, execution in step 210.Suppose that the bandwidth value that ISP provides is 10Mbps, maximum is 9.92Mbps in preceding 20 of the interface flow speed, minimum value 9.85Mbps, because (9.92-9.85)/10=0.7%, then this moment, interface flow speed peak F can characterize circuit actual bandwidth value preferably.
Step 210, adjusting line bandwidth value B is (B+3F)/4, line bandwidth value can be slightly larger than interface flow speed peak F, has so just vacateed the space of certain flow burst, so that the more effective detection line actual bandwidth of follow-up energy.
Step 211, adjusting line bandwidth value B is interface flow speed peak F.
Step 212 judges whether system's cycle of operation reach one day, if execution in step 213 then, otherwise execution in step 202.After system moves 1 day for the first time, can meet this judgement, move after 2 days, also meet this judgement, the rest may be inferred.
Step 213, adjusting line bandwidth value is current line bandwidth value B and half of interface flow speed peak F sum.
Step 214 is upgraded bandwidth adjusted value sequence.Example in the refer step 205,206, upgraded bandwidth adjusted value sequence after, this sequence be (10Mbps, 9Mbps, 8.8Mbps).
According to as above execution mode, suppose that certain local net network keeper has bought 10Mbps optical fiber to ISP and exclusively enjoyed access, suppose that the circuit actual bandwidth is 9.7Mbps.System initialization line bandwidth B is 10Mbps, and this Time Bandwidth adjusted value sequence is (10Mbps); After system had moved the time, interface flow speed peak F was 9.5Mbps, and this moment, to adjust line bandwidth B be (B+F)/2=(10+9.5)/2=9.75Mbps, renewal bandwidth adjusted value sequence be (10Mbps, 9.75Mpbs); When system ran to second day, interface flow speed peak value still was 9.5Mbps, and this moment, to adjust line bandwidth B be (B+F)/2=(9.75+9.5)/2=9.625Mbps, renewal bandwidth adjusted value sequence be (10Mbps, 9.75Mpbs, 9.625Mbps); After this new interface flow speed peak F to have occurred be 9.65Mbps in system, and according to step 205, Bf is 9.75Mbps, then adjusting line bandwidth is (Bf+F)/2=(9.75+9.65)/2=9.7Mbps, upgrade bandwidth adjusted value sequence and be (10Mbps, 9.75Mbps, 9.7Mbps); After this when system operation time reaches a week, in preceding 20 of the interface flow rate value, maximum is 9.71Mbps, minimum value is 9.69Mbps, both differ less than ISP 1% of bandwidth value are provided, and then adjusting line bandwidth is 9.71Mbps, and upgrading bandwidth adjusted value sequence is (10Mbps, 9.75Mbps, 9.71Mbps); Follow-up continuation continues to detect according to flow process shown in Figure 6 to be handled.
And for example, suppose that certain local net network keeper has bought 10Mbps optical fiber to ISP and exclusively enjoyed access, suppose that the circuit actual bandwidth is 11Mbps.System initialization line bandwidth B is 10Mbps, and this Time Bandwidth adjusted value sequence is (10Mbps); After system had moved one day, interface flow speed peak F was 10.5Mbps, because F＞Bc, then adjusted line bandwidth B=Bc, i.e. 10Mbps, and withdraw from the bandwidth detection flow process.
