Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below by specific embodiment knot Attached drawing is closed to be described in further detail the embodiment of the present invention.It should be appreciated that specific embodiment described herein is only used to It explains the present invention, is not intended to limit the present invention.
Embodiment one:
In order to solve directly to calculate port status according to the data acquisition results to chip in transmission device in the prior art In the scheme of parameter, the state parameter inaccuracy of port can be led to because of inaccuracy of data acquisition itself, and then lead to basis The problem of quality of the network planning and maintenance that the port status parameter carries out is not high, does not meet actual conditions, the present embodiment mentions For a kind of port status parameter acquiring method, the flow chart of the port status parameter acquiring method shown referring to Figure 1:
S102, the transmission performance data of transmission device port are acquired.
In the present embodiment, port status parameter obtaining device is acquired the transmission performance data of transmission device port, Can be by the way of periodic data acquisition: when data collection cycle reaches, port status parameter obtaining device be to port Transmission performance data be acquired.Transmission performance data may include transmission totalframes and transmission total byte in receiving direction Number also may include transmission totalframes and transmission total bytes on sending direction, and certainly, port status parameter obtaining device is also The transmission totalframes and transmission total bytes in port sending direction and receiving direction can be acquired simultaneously.It is beyond all doubt, For a port, there is no direct incidence relations for the state parameter of receiving direction and sending direction, therefore, big absolutely In most cases, for the same port, port status parameter obtaining device is respectively on sending direction and receiving direction State parameter is obtained, so, for the transmission performance data of each receiving direction of sending direction, port status parameter obtains dress Set to obtain respectively.
Described port can be ethernet port in the present embodiment, however it should be appreciated that in addition to ethernet port In addition, it can also be the other kinds of port for assuming responsibility for data transfer task.
S104, current collected transmission performance data exception is determined.
After collecting the transmission performance data of port, port status parameter obtaining device can acquire feelings according to data Condition determines whether current collected transmission performance data are abnormal.It is worth noting that, exception signified in the present embodiment be by Caused by inaccuracy of data acquisition itself.So port status parameter obtaining device determines current collected transmission performance Whether data are abnormal, and actually namely whether judgement is accurate for the acquisition of transmission performance data.In other words, port status is joined Number acquisition device is when determining current collected transmission performance data exception, end caused by excluding because of live network situation etc. Port transmission performance data abnormal conditions.For example, if the current transmission performance data of ethernet port differ very with normal level Far, but this is because then this is not belonging to so-called in the present embodiment caused by the reasons such as the network state difference at data acquisition moment Abnormal conditions；If collected transmission performance data differ greatly with normal level, but this is because data acquisition inaccuracy Caused by, that is to say, that collected transmission performance data can not characterize the current actual conditions of ethernet port, then this belongs to Abnormal conditions in this present embodiment.
By the agency of mistake in front, cause the possibility of data acquisition results exception have in this way of both reason: one, data Acquisition tasks are seized by other high-priority tasks, cause data acquisition results not comprehensive, inaccurate；Two, port status parameter The data collection cycle of acquisition device is asynchronous with the measurement period of port ARM chip.Certainly, it only lists here and compares allusion quotation Type, than major two reasons, can also include other reasons other than above-mentioned both sides reason.
In the present embodiment, data acquisition situation includes the collection process and collection result to transmission performance data, institute Being acquired when situation determines collected transmission performance data exception with, port status parameter obtaining device according to data at least can be with Including both sides meaning in this way: first, port status parameter obtaining device is determined according to the collection result of transmission performance data Current data acquisition itself is inaccurate；Second, port status parameter obtaining device is according to the collection process of transmission performance data Determine that current data acquisition itself is inaccurate.
For above-mentioned in a first aspect, port status parameter obtaining device determines according to the collection result to transmission performance data Transmission performance data exception out, for example, port status parameter obtaining device determines that collected transmission performance data are exceptional value, And determine that transmission performance data are that the continuous integration number of exceptional value has reached preset threshold according in preceding data acquisition situation.This In " the acquiring situation in preceding data " refer to the acquisition of this data before data acquire situation.It is assumed that being currently M The secondary acquisition for carrying out transmission performance data, then in the acquisition of preceding data it may be the case that the 1st time to the M-1 time data acquire in one Secondary or multiple situation.
In a kind of embodiment of the present embodiment, when port status parameter obtaining device collect transmission performance data it Afterwards, can determine whether collected transmission performance data are exceptional values, it, can be to characterization if transmission performance data are exceptional values The continuous integration number for continuously exceptional value occur is increased.If transmission performance data are not exceptional values, by current company Continuous cumulative number is reset.For example, be currently the acquisition that the 5th carries out transmission performance data, before this, the 3rd time and the 4th number It is exceptional value according to transmission performance data in collection result, then before carrying out the acquisition of the 5th transmission performance data, continuous integration The value of number is " 2 ".If the collection result of the 5th characterizes transmission performance data exception, continuous integration number will be further added by 1 Become " 3 ".If subsequent and carried out the acquisition of the 6th transmission performance data to port, and the value of transmission performance data is not Exceptional value, then after the 6th data acquire, continuous integration time numerical value will become " 0 ".
According to above-mentioned introduction it is found that port status parameter obtaining device is determining transmission performance number according to data acquisition results According to it is abnormal when, need to meet two such condition: firstly, in current data acquisition results transmission performance data be exceptional value. Transmission performance data include transmission totalframes and transmission total bytes on reception and/or sending direction, as long as transmission totalframes It is exceptional value with the value of any one in transmission total bytes, then port status parameter obtaining device can be assumed that transmission performance Data are exceptional value.In an example of the present embodiment, exceptional value 0, as long as then transmission totalframes and transmission total byte The value of any one in number is 0, then it can be assumed that the value of transmission performance data is exceptional value.Currently acquiring resulting transmission On the basis of performance data meets the condition for exceptional value, port status parameter obtaining device also needs to acquire according in preceding data Situation determines that transmission performance data are whether the continuous integration number of exceptional value has had reached preset threshold.
For example it is assumed that the size of preset threshold is 3, then it is directed to above-mentioned example, is carried out in port status parameter obtaining device After the acquisition of the 5th transmission performance data, data acquisition results have just met above-mentioned two condition simultaneously, therefore, port shape State parameter obtaining device can be determined that inaccuracy itself is influenced current collected transmission performance data by data acquisition Exception is showed.
S106, the current state parameter in processing acquisition port is optimized in preceding state parameter to port.
When port status parameter obtaining device is determining current collected according to data acquisition results or data acquisition Transmission performance data are acquired by data when itself being influenced and occurring abnormal, and port status parameter obtaining device is calculating port When current state parameter, processing can be optimized to obtain the current state parameter in port according in preceding state parameter.Benefit Resulting current state parameter after handling is optimized used in preceding state parameter, relative to directly according to abnormal transmission performance number For calculating the state parameter obtained, it is more nearly the current truth in port, can be excluded directly according to exception in this way Transmission performance data calculate the problem of inaccuracy caused by port status parameter.
For the scene for determining transmission performance data exception according to data acquisition results, port status parameter obtaining device exists Port current state parameter is obtained, such as when the currently practical flow in port, it can be according to being obtained in preceding data acquisition Port actual flow optimizes processing, so that obtaining this data acquires corresponding port actual flow, as shown in Figure 2:
Practical stream corresponding at least one of S202, the M-N times to the M-1 times transmission performance data acquisition of acquisition Amount.
It is assumed that this time data acquisition is to be acquired to the transmission performance data of port for the M times, then firstly, port status The corresponding actual flow of M-1 to the M-N times data acquisition before parameter obtaining device obtains the acquisition of this data.Wherein, N Value be more than or equal to 1.It is understood that the data that port status parameter obtains can be M-1 to the M-N times data and acquire Actual flow corresponding to middle one or more.
S204, the current actual flow in port is calculated in preceding actual flow according to what is got using smoothing algorithm.
In some examples of the present embodiment, port status parameter obtaining device can be acquired only with this data Time does optimization processing according to smoothing algorithm in preceding actual flow closest to one or more, to obtain this number Port actual flow when according to acquisition.But in other examples, port status parameter obtaining device also available time From the farther away one or more of this data acquisition in preceding actual flow.Continue to assume that the acquisition of this data is the 5th, if the The collected transmission performance data exceptions of 5 data acquisition institute, then port status parameter obtaining device can be according to the 4th and the 3 data acquisition corresponding port actual flow determines the current actual flow in port, can also according to the 1st time and/or 2nd actual flow carrys out smoothing computation, obtains current actual flow.
The number selected in preceding actual flow is not limited in the present embodiment, it can be by the customized setting of gateway personnel.No It crosses theoretically, smoothing algorithm is being used to optimize processing in preceding actual flow to obtain the current actual flow in port When, selection it is more in preceding actual flow, calculated result with actual conditions to agree with degree also higher.
It should be understood that the acquisition of the present embodiment middle port state parameter acquisition device should be energy in preceding actual flow Enough as close possible to port in the data for corresponding to moment truth.That is, participate in smooth optimization processing in preceding reality What flow was not necessarily calculated according to data acquisition results, it is also possible to before being basis in preceding actual port flow What optimization processing obtained.For example it is assumed that being currently that the 5th carries out the acquisition of transmission performance data, port status parameter obtaining device It, can each reality in conjunction with corresponding to the 4th to the 1st data acquisition after determining transmission performance data exception according to collection result One or more of border flow optimizes processing and obtains the actual flow of port when the data acquisition of the 5th.It is assumed that port What state parameter acquisition device utilized is that the 3rd data acquire reality corresponding to corresponding actual flow and the acquisition of the 4th data The corresponding actual flow of the 5th data acquisition is calculated to optimize in border flow, but the practical stream that the 3rd data acquisition is corresponding Amount is actually also likely to be to be calculated according to the corresponding actual flow optimization of the 1st data acquisition and the 2nd data acquisition 's.Because acquiring the port actual flow at moment by resulting 3rd data of optimization processing, than being acquired according to the 3rd data Port flow when the port flow magnitude that resulting transmission performance data are calculated can more be reflected in the 3rd data acquisition of progress Truth.Similarly, if needing the 5th data acquiring corresponding actual flow as preceding in the follow-up process Actual flow, to calculate the port actual flow at corresponding moment, the then corresponding actual flow of the 5th data acquisition of its selection It should also be as being to optimize processing by smoothing algorithm to obtain, rather than acquire resulting abnormal transmission according to the 5th data What performance data was directly calculated.
Although not illustrating directly in aforementioned exemplary, it should be understood that, present port is determined every time After actual flow, which should be associated storage with the serial number of corresponding data times of collection, with after an action of the bowels Continuous needs are to extract to use.
Port status parameter acquiring method provided in this embodiment is acquired it in the transmission performance data to port Afterwards, it can determine whether current collected transmission performance data receive data according to data acquisition results or data acquisition The influence of acquisition inaccuracy itself.If it is determined that causing data acquisition results inaccurate because of inaccuracy of data acquisition itself, then Directly will not determine the current state parameter in port according to data acquisition results, but combine the port in preceding state parameter, The state parameter for being more bonded practical situation is calculated using smoothing algorithm optimization, to evade abnormal transmission performance data opposite end The negative effect that mouth state parameter calculates, promotes the accuracy of port status parameter.
Embodiment two:
The present embodiment will continue to carry out the port status parameter acquiring method in the present invention on the basis of example 1 It introduces, refers to the flow chart shown in Fig. 3:
S302, port status parameter obtaining device are acquired the transmission performance data of transmission device port.
In the present embodiment, port status parameter obtaining device is periodically to the transmission performance data of transmission device port It is acquired.It is assumed that the period of data collection cycle is 1s, that is to say, that in every 1s, port status parameter obtaining device will One acquisition is carried out to the transmission performance data of port.In 1 minute, there are 60 data collection cycles, so, port status ginseng The transmission performance data that number acquisition device can carry out 60 times to port acquire.
It, can be according to number when determining whether collected transmission performance data are abnormal due to port status parameter obtaining device Determined according to collection process, that is, the second aspect referred in embodiment one.So being obtained for the ease of port status parameter Take device determine collected transmission performance data whether the influence by data acquisition inaccuracy, in the present embodiment, port shape State parameter obtaining device will record down the start/stop time of this transmission performance data acquisition, that is, starting transmission performance data When acquisition, at the beginning of port status parameter obtaining device will record lower data acquisition；It acquires and completes in transmission performance data When, port status parameter obtaining device will record the finish time of lower data acquisition again.
S304, port status parameter obtaining device judge whether collected transmission performance data are abnormal.
In the present embodiment, it mainly introduces port status parameter obtaining device and transmission performance is determined according to data acquisition Data whether Yi Chang scheme, provide an example here: it is assumed that being currently the M times progress data acquisition, then according to front It introduces, will record the M times data acquisition before port status parameter obtaining device carries out the acquisition of transmission performance data to port At the beginning of tM, and data acquisition finish time t when collecting dataM', to be determined according to the time at two moment This data acquires the time it takes d t outM, i.e. tM’-tM.Such as be currently the 5th progress transmission performance data acquisition, At the time of this time data acquisition starts, port status parameter obtaining device will record t5 of lower start time.When the 5th data acquire At the end of, port status parameter obtaining device will record t5 ' of lower finish time again, then according to start time t5 and finish time T5 ' determines the current acquisition duration dt5 of the 5th data acquisition.Simultaneously as in front 4 progress data acquisitions when, Port status parameter obtaining device also will record lower each time at the beginning of with finish time, and calculate each secondary data acquisition and spend The acquisition duration taken.So in the present embodiment, port status parameter obtaining device can judge currently according to the following conditions Whether by data acquisition, inaccuracy is influenced and exception occurs collected transmission performance data in itself:
The acquisition of preceding transmission performance data spent in preceding acquisition duration dtM-1More than or equal to the first duration threshold value；
When previous transmission performance data acquire the current acquisition duration dt spentMMore than or equal to the second duration threshold value；
When previous transmission performance data acquire finish time tM' the same transmission performance data acquire finish time tM-1’ Between interval be not equal to transmission performance data collection cycle T.Since in each transmission performance data collection cycle T, port State parameter acquisition device will do it a data acquisition, so, under normal circumstances, T=tM′-tM-1′。
In above three condition, if this time data acquisition meet wherein any one, port status parameter obtains It takes device i.e. and can determine that inaccuracy is influenced and exception occurs current collected transmission performance data in itself by data acquisition. In other words, if port status parameter obtaining device determine preceding transmission performance data acquire spent in preceding acquisition duration dtM-1Less than the first duration threshold value, and the current acquisition duration dt that previous transmission performance data collection is spentMWhen less than second Long threshold value, and previous transmission performance data collection finish time tM' the same transmission performance data acquire finish time tM-1' between interval be equal to transmission performance data collection cycle T, just can be determined that Current data acquisition result not by data The influence of acquisition is normal.
For example, be directed to above-mentioned example, port status parameter obtaining device need to determine the 4th data acquisition spent Relationship between preceding acquisition duration dt4 and the first duration threshold value, this data current acquisition duration dt5 for being spent of acquisition and the Between relationship and the 5th data acquisition finish time t5 ' between two duration threshold values and the 4th data acquisition finish time t4 ' Interval with the relationship between data collection cycle T.The present embodiment does not limit sentencing for port status parameter obtaining device specifically Timing sequence, such as in a kind of example, port status parameter obtaining device first determines whether dt5 is more than or equal to the second duration threshold Then value determines whether dt4 is more than or equal to the first duration threshold value, finally determine whether t5 '-t4 ' is equal to T again；But in this implementation In another example of example, port status parameter obtaining device first determines whether dt4 is more than or equal to the first duration threshold value, finally Determine whether dt5 is more than or equal to the second duration threshold value.
It should be appreciated that when port status parameter obtaining device is when determining that any one above-mentioned condition meets, It can not continue to determine whether residue condition meets, determine the time to save.
It is understood that being said if current data acquisition meets any one in above three condition Bright the M times data take time longer than the normal acquisition time, therefore port status parameter obtaining device when acquisition Determine whether transmission performance data are actually at the time of determining to carry out data acquisition extremely according to data acquisition, if The situation that high-priority task seizes data acquisition session has occurred.If the judgement result of port status parameter obtaining device is It is then to execute S306；Otherwise, S308 is executed.
S306, port status parameter obtaining device optimize the current state in processing acquisition port in preceding state parameter Parameter.
If determining current collected transmission performance data exception, port shape according to the collection process that data acquire State parameter obtaining device needs to optimize processing in preceding state parameter to obtain the current state in the port and join to the port Number.In the following, being illustrated by taking the transmission rate for obtaining the port as an example, Fig. 4 is referred to:
S402, at least one of corresponding transmission rate is acquired according to the M-N times to the M-1 times transmission performance data It determines in preceding rate.
Due to, this time data acquisition be the M times the transmission performance data of port are acquired, so, optionally, if The transmission rate obtained after the M-1 times transmission performance data acquisition is 0, then port status parameter obtaining device obtains M-N The corresponding transmission rate of secondary to the M-1 times transmission performance data acquisition, and the average value for calculating N number of transmission rate is used as preceding Rate, N are greater than 1.If the transmission rate obtained after the M-1 times transmission performance data acquisition is not 0, port status parameter The transmission performance data that acquisition device directly acquires the M-1 times acquire corresponding transmission rate and are used as in preceding rate.
It is assumed that being currently that the 5th carries out the acquisition of transmission performance data, if port status parameter obtaining device is adopted according to data When collection process determines the acquisition of this data, data acquisition session is seized by high-priority task, then port status parameter obtains The transmission rate for taking the available the 4th data acquisition of device corresponding is used as in preceding rate.If the transmission rate of the 4th is 0, then the corresponding transmission speed of port status parameter obtaining device available 2nd time, the 3rd time and the acquisition of the 4th data Rate, and averaged as the 5th data acquire when in preceding rate.
S404, the current transmission rate in port is obtained according in preceding rate calculations using smoothing algorithm.
When port status parameter obtaining device get current data acquisition it is corresponding after preceding rate, Ke Yigen Current transmission rate is calculated according to following formula:
Wherein, SMFor current transmission rate, SM-1For in preceding rate.K is adjustment deviation, and value is equal toThe size of value is between 0~1, tM' the finish time acquired for the M times data, the tM-1' be The finish time of the M-1 times data acquisition.AMFor the current actual flow in port, the value of the actual flow be can be according to implementation What the optimization processing scheme introduced in example one obtained, it is also possible to according to when previous collected transmission performance data are calculated 's.Specifically, if in calculating port when current actual flow, port status parameter obtaining device determines transmission performance number According to exception, then smooth optimization processing can be carried out in preceding actual flow according to the scheme provided in previous embodiment, and then obtain To the A when acquisition of this dataM.If port status parameter obtaining device determines that transmission performance data are normal, then it can be straight It connects and A is calculated according to collected transmission performance data combination following formulaM:
AM=transmission total bytes+(the transmission port totalframes * frame gap)
It should be appreciated that for the actual flow of port sending direction, should according to the total bytes of sending direction with Totalframes is calculated, then should be according to the total joint number and totalframes of receiving direction for the actual flow of port receiving direction It is calculated.
It is current that S308, port status parameter obtaining device directly calculate exit port according to collected transmission performance data State parameter.
If port status parameter obtaining device is currently collected according to data acquisition results or data acquisition determination Transmission performance data it is normal, influenced whether inaccurate by data acquisition itself, then port status parameter obtaining device Can the current state parameter of exit port directly be calculated according to collected transmission performance data.Such as the biography current for port Defeated rate can calculate according to the following formula:
In the present embodiment, no matter port status parameter obtaining device is which kind of mode to have got port by currently The transmission rate can all be associated with port numbers and save by transmission rate.It should be understood that when saving, also Should associated storage can characterize data corresponding to the transmission rate acquisition serial number information.
Port status parameter acquiring method provided in an embodiment of the present invention is acquired in the transmission performance data to port Later, it can determine whether current collected transmission performance data receive number according to data acquisition results or data acquisition According to the influence of acquisition inaccuracy itself, objective judgement is carried out to data acquisition results.Determining current collected transmission performance Data are normal datas, when not acquired itself by data is influenced, directly calculate that obtain port current according to the data State parameter.When determining that collected transmission performance data have received the inaccurate influence of receipt acquisition itself, not directly It is calculated according to this transmission performance data for being unable to characterize port actual conditions and obtains the current state parameter in port, but according to The port optimizes processing in preceding state parameter, thus acquisition and the closer state parameter of actual conditions, and then be subsequent The network planning and maintenance more believable basis is provided, promote the quality of the network planning and maintenance.
Embodiment three:
The present embodiment provides a kind of port status parameter obtaining devices, refer to Fig. 5:
Port status parameter obtaining device 50 includes that data acquisition module 502, abnormal determination module 504 and state obtain Module 506, wherein data acquisition module 502 is for being acquired the transmission performance data of transmission device port；Abnormal determination Module 504 is for determining current collected transmission performance data exception；And state acquisition module 506 is used for port preceding State parameter optimizes processing and obtains the current state parameter in port.
In the present embodiment, data acquisition module 502 is acquired the transmission performance data of transmission device port, can adopt The mode acquired with periodic data: when data collection cycle reaches, transmission performance number of the data acquisition module 502 to port According to being acquired.Transmission performance data may include transmission totalframes and transmission total bytes in receiving direction, also can wrap The transmission totalframes and transmission total bytes on sending direction are included, certainly, data acquisition module 502 can also acquire port simultaneously Transmission totalframes and transmission total bytes on sending direction and receiving direction.It is beyond all doubt, for a port, There is no direct incidence relations for the state parameter of receiving direction and sending direction, therefore, in most cases, for same A port, data acquisition module 502 be the state parameter on sending direction and receiving direction is obtained respectively, so, For the transmission performance data of each receiving direction of sending direction, data acquisition module 502 can also obtain respectively.
Described port can be ethernet port in the present embodiment, however it should be appreciated that in addition to ethernet port In addition, it can also be the other kinds of port for assuming responsibility for data transfer task.
After data acquisition module 502 collects the transmission performance data of port, abnormal determination module 504 can basis Data acquire situation and determine whether current collected transmission performance data are abnormal.It is worth noting that, signified in the present embodiment Exception be as data acquisition itself inaccuracy caused by.So abnormal determination module 504 determines current collected transmission Whether performance data is abnormal, and actually namely whether judgement is accurate for the acquisition of transmission performance data.In other words, sentence extremely Cover half block 504 is when determining current collected transmission performance data exception, end caused by excluding because of live network situation etc. Port transmission performance data abnormal conditions.For example, if the current transmission performance data of ethernet port differ very with normal level Far, but this is because then this is not belonging to so-called in the present embodiment caused by the reasons such as the network state difference at data acquisition moment Abnormal conditions；If collected transmission performance data differ greatly with normal level, but this is because data acquisition inaccuracy Caused by, that is to say, that collected transmission performance data can not characterize the current actual conditions of ethernet port, then this belongs to Abnormal conditions in this present embodiment.
By the agency of mistake in front, cause the possibility of data acquisition results exception have in this way of both reason: one, data Acquisition tasks are seized by other high-priority tasks, cause data acquisition results not comprehensive, inaccurate；Two, data acquisition module 502 data collection cycle is asynchronous with the measurement period of port ARM chip.Certainly, it only lists here than more typical, ratio Major two reasons can also include other reasons other than above-mentioned both sides reason.
In the present embodiment, data acquisition situation includes the collection process and collection result to transmission performance data, institute With abnormal determination module 504 acquires situation and determine when collected transmission performance data exception according to data at least may include Meaning of both in this way: first, abnormal determination module 504 determines current data according to the collection result of transmission performance data Acquisition inaccuracy itself；Second, abnormal determination module 504 determines that current data are adopted according to the collection process of transmission performance data Collection inaccuracy itself.
For above-mentioned in a first aspect, abnormal determination module 504 determines biography according to the collection result to transmission performance data Defeated performance data is abnormal, for example, abnormal determination module 504 determines that collected transmission performance data are exceptional value, and according to Preceding data acquisition situation determines that transmission performance data are that the continuous integration number of exceptional value has reached preset threshold.Described here Data before " acquiring situation in preceding data " refers to the acquisition of this data acquire situation.It is assumed that being currently to be passed for the M times The acquisition of defeated performance data, then in the acquisition of preceding data it may be the case that one or many in the 1st time to the M-1 times data acquisition The case where.
It is abnormal after data acquisition module 502 collects transmission performance data in a kind of embodiment of the present embodiment Determination module 504 can determine whether collected transmission performance data are exceptional values, if transmission performance data are exceptional values, The continuous integration number that continuously exceptional value can occur to characterization increases.It, will if transmission performance data are not exceptional values Current continuous integration number is reset.For example, being currently the acquisition that the 5th carries out transmission performance data, before this, the 3rd time It is exceptional value with transmission performance data in the 4th data acquisition results, then acquires it in progress the 5th transmission performance data Before, the value of continuous integration number is " 2 ".If the collection result of the 5th characterizes transmission performance data exception, continuous integration number 1 will be further added by and become " 3 ".If subsequent and carried out the acquisition of the 6th transmission performance data to port, and transmission performance data Value be not exceptional value, then after the 6th data acquire, continuous integration time numerical value will become " 0 ".
According to above-mentioned introduction it is found that abnormal determination module 504 is determining that transmission performance data are different according to data acquisition results Chang Shi needs to meet two such condition: firstly, transmission performance data are exceptional value in current data acquisition results.Transmission Performance data includes transmission totalframes and transmission total bytes on reception and/or sending direction, as long as transmission totalframes and biography The value of any one in defeated total bytes is exceptional value, then abnormal determination module 504 is it can be assumed that transmission performance data are different Constant value.In an example of the present embodiment, exceptional value 0, as long as then appointing in transmission totalframes and transmission total bytes The value of meaning one is 0, then it can be assumed that the value of transmission performance data is exceptional value.Currently acquiring resulting transmission performance data On the basis of meeting the condition for exceptional value, abnormal determination module 504 also needs to determine transmission according in preceding data acquisition situation Performance data is whether the continuous integration number of exceptional value has had reached preset threshold.
For example it is assumed that the size of preset threshold is 3, then it is directed to above-mentioned example, carries out the 5th in data acquisition module 502 After the acquisition of transmission performance data, data acquisition results have just met above-mentioned two condition simultaneously, therefore, abnormal determination module 504 can be determined that inaccuracy is influenced and exception occurs current collected transmission performance data in itself by data acquisition.
When abnormal determination module 504 determines current collected transporting according to data acquisition results or data acquisition Energy data are acquired by data when itself being influenced and occurring abnormal, and state acquisition module 506 is calculating the current state in port When parameter, processing can be optimized to obtain the current state parameter in port according in preceding state parameter.Using in preceding state Parameter optimizes resulting current state parameter after processing, obtains relative to directly being calculated according to abnormal transmission performance data State parameter for, be more nearly the current truth in port, can exclude so directly according to abnormal transmission performance number According to the problem for calculating inaccuracy caused by port status parameter.
For the scene for determining transmission performance data exception according to data acquisition results, state acquisition module 506 is being obtained Port current state parameter, such as when the currently practical flow in port, it can be according to the port obtained in preceding data acquisition Actual flow optimizes processing, so that obtaining this data acquires corresponding port actual flow.
Firstly, state acquisition module 506 obtains at least one of the M-N times to the M-1 times transmission performance data acquisition Corresponding actual flow.It is assumed that this time data acquisition is to be acquired to the transmission performance data of port for the M times, then firstly, The corresponding actual flow of M-1 to the M-N times data acquisition before state acquisition module 506 obtains the acquisition of this data.Its In, the value of N is more than or equal to 1.It is understood that the data that port status parameter obtains can be M-1 to the M-N times data Actual flow corresponding to one or more in acquisition.
Then, port is calculated in preceding actual flow according to what is got using smoothing algorithm in state acquisition module 506 Current actual flow.In some examples of the present embodiment, state acquisition module 506 can be adopted only with this data The collection time does optimization processing according to smoothing algorithm in preceding actual flow closest to one or more, to obtain this Port actual flow when data acquire.But in other examples, state acquisition module 506 also the available time from this The secondary farther away one or more of data acquisition is in preceding actual flow.Continue to assume that the acquisition of this data is the 5th, if the 5th The collected transmission performance data exception of data acquisition institute, then state acquisition module 506 can be according to the 4th and the 3rd data Acquisition corresponding port actual flow determines the current actual flow in port, can also be according to the 1st time and/or the 2nd time Actual flow carrys out smoothing computation, obtains current actual flow.
The number selected in preceding actual flow is not limited in the present embodiment, it can be by the customized setting of gateway personnel.No It crosses theoretically, smoothing algorithm is being used to optimize processing in preceding actual flow to obtain the current actual flow in port When, selection it is more in preceding actual flow, calculated result with actual conditions to agree with degree also higher.
It should be understood that in the present embodiment state acquisition module 506 obtain should can use up in preceding actual flow Port be may be close in the data of corresponding moment truth.That is, participate in smooth optimization processing in preceding actual flow Not necessarily calculated according to data acquisition results, it is also possible to before being basis in preceding actual port flow optimization What processing obtained.For example it is assumed that being currently that the 5th carries out the acquisition of transmission performance data, abnormal determination module 504 is tied according to acquisition It, can be in conjunction with the 4th into the corresponding each actual flow of the 1st data acquisition after fruit determines transmission performance data exception One or more optimizes processing and obtains the actual flow of port when the data acquisition of the 5th.It is assumed that state acquisition module 506 What is utilized is that the 3rd data acquire actual flow corresponding to corresponding actual flow and the acquisition of the 4th data to optimize calculating It obtains the 5th data and acquires corresponding actual flow, but the 3rd corresponding actual flow of data acquisition is actually also likely to be It is calculated according to the corresponding actual flow optimization of the 1st data acquisition and the 2nd data acquisition.Because by optimization The port actual flow for managing the resulting 3rd data acquisition moment, than acquiring resulting transmission performance data according to the 3rd data The port flow magnitude calculated can more be reflected in the truth of port flow when carrying out the 3rd data acquisition.Similarly, It is used as if needing the 5th data acquiring corresponding actual flow in the follow-up process in preceding actual flow, with calculating pair The port actual flow at moment is answered, then the actual flow that the 5th data acquisition of its selection is corresponding should also be as being by smooth Algorithm optimizes what processing obtained, rather than acquires resulting abnormal transmission performance data according to the 5th data and directly calculate Out.
Although not illustrating directly in aforementioned exemplary, it should be understood that, present port is determined every time After actual flow, which should be associated storage with the serial number of corresponding data times of collection, with after an action of the bowels Continuous needs are to extract to use.
Port status parameter obtaining device provided in this embodiment is acquired it in the transmission performance data to port Afterwards, it can determine whether current collected transmission performance data receive data according to data acquisition results or data acquisition The influence of acquisition inaccuracy itself.If it is determined that causing data acquisition results inaccurate because of inaccuracy of data acquisition itself, then Directly will not determine the current state parameter in port according to data acquisition results, but combine the port in preceding state parameter, The state parameter for being more bonded practical situation is calculated using smoothing algorithm optimization, to evade abnormal transmission performance data opposite end The negative effect that mouth state parameter calculates, promotes the accuracy of port status parameter.
Example IV:
The present embodiment will be introduced the port status parameter obtaining device 50 in the present invention continuing with Fig. 5:
In the present embodiment, data acquisition module 502 periodically carries out the transmission performance data of transmission device port Acquisition.It is assumed that the period of data collection cycle is 1s, that is to say, that in every 1s, data acquisition module 502 will be to the biography of port Defeated performance data carries out one acquisition.In 1 minute, there are 60 data collection cycles, so, the meeting pair of data acquisition module 502 Port carries out 60 transmission performance data acquisitions.
When determining whether collected transmission performance data are abnormal due to abnormal determination module 504, it can be adopted according to data Collection process is determined, that is, the second aspect referred in embodiment one.So true for the ease of abnormal determination module 504 Whether fixed collected transmission performance data are influenced by data acquisition inaccuracy, in the present embodiment, data acquisition module 502 It will record down the start/stop time of this transmission performance data acquisition, that is, when starting the acquisition of transmission performance data, data acquisition At the beginning of module 502 will record lower data acquisition；When transmission performance data acquire completion, data acquisition module 502 is again It will record the finish time of lower data acquisition.
In the present embodiment, it mainly introduces abnormal determination module 504 and transmission performance data is determined according to data acquisition Whether Yi Chang scheme, provide an example here: it is assumed that be currently the M times progress data acquisition, then according to the introduction of front, At the beginning of will record the M times data acquisition before data acquisition module 502 carries out the acquisition of transmission performance data to port tM, and data acquisition finish time t when collecting dataM', to determine this data according to the time at two moment Acquire the time it takes d tM, i.e. tM’-tM.Such as currently be the 5th carry out the acquisition of transmission performance data, adopted in this secondary data At the time of collection starts, data acquisition module 502 will record t5 of lower start time.At the end of the acquisition of the 5th data, data acquisition Module 502 will record t5 ' of lower finish time again, then determine that the 5th data are adopted according to start time t5 and finish time t5 ' The current acquisition duration dt5 of collection.Simultaneously as in front 4 progress data acquisitions when, data acquisition module 502 also can At the beginning of recording each time with finish time, and calculate each secondary data and acquire spent acquisition duration.So in this reality It applies in example, abnormal determination module 504 can judge whether current collected transmission performance data are counted according to the following conditions There is exception according to the influence of acquisition inaccuracy itself:
The acquisition of preceding transmission performance data spent in preceding acquisition duration dtM-1More than or equal to the first duration threshold value；
When previous transmission performance data acquire the current acquisition duration dt spentMMore than or equal to the second duration threshold value；
When previous transmission performance data acquire finish time tM' the same transmission performance data acquire finish time tM-1’ Between interval be not equal to transmission performance data collection cycle T.Since in each transmission performance data collection cycle T, port State parameter acquisition device will do it a data acquisition, so, under normal circumstances, T=tM′-tM-1′。
In above three condition, if this time data acquisition meet wherein any one, abnormal determination module 504 It can determine that inaccuracy is influenced and exception occurs current collected transmission performance data in itself by data acquisition.Change speech It, if abnormal determination module 504 determine preceding transmission performance data acquire spent in preceding acquisition duration dtM-1It is less than First duration threshold value, and the current acquisition duration dt that previous transmission performance data collection is spentMLess than the second duration threshold value, and And previous transmission performance data collection finish time tM' the same transmission performance data acquire finish time tM-1' between Every being equal to transmission performance data collection cycle T, it just can be determined that Current data acquisition result is not influenced by data acquisition, be Normally.
For example, be directed to above-mentioned example, abnormal determination module 504 need to determine the 4th data acquisition spent adopted preceding Collect the relationship between duration dt4 and the first duration threshold value, when this data acquires the current acquisition duration dt5 and second spent Between between relationship and the 5th data acquisition finish time t5 ' between long threshold value and the 4th data acquisition finish time t4 ' Relationship between same data collection cycle T.The present embodiment does not limit the judgement timing of abnormal determination module 504, example specifically Such as in a kind of example, abnormal determination module 504 first determines whether dt5 is more than or equal to the second duration threshold value, then determines dt4 Whether it is more than or equal to the first duration threshold value, finally determines whether t5 '-t4 ' is equal to T again；But in another example of the present embodiment In the middle, abnormal determination module 504 first determines whether dt4 is more than or equal to the first duration threshold value, finally determines whether dt5 is more than or equal to Second duration threshold value.
It should be appreciated that when abnormal determination module 504 is when determining that any one above-mentioned condition meets, it can not It is further continued for determining whether residue condition meets, determines the time to save.
It is understood that being said if current data acquisition meets any one in above three condition Bright the M times data take the time longer than the normal acquisition time when acquisition, therefore hold 504 basis of abnormal determination module Data acquisition determines whether transmission performance data are actually at the time of determining to carry out data acquisition extremely, if occurs High-priority task seizes the situation of data acquisition session.If the judgement result of abnormal determination module 504 is yes, state It obtains module 506 and optimizes the current state parameter in processing acquisition port in preceding state parameter；Otherwise state acquisition module 506 directly calculate the current state parameter of exit port according to collected transmission performance data.
If determining that current collected transmission performance data exception, state obtain according to the collection process that data acquire Modulus block 506 needs to optimize processing in preceding state parameter to the port to obtain the current state parameter in the port.Under Face is illustrated by taking the transmission rate for obtaining the port as an example:
Firstly, the transmission that state acquisition module 506 is corresponding according to the M-N times to the M-1 times transmission performance data acquisition At least one of rate is determined in preceding rate.Due to, this time data acquisition be the M times transmission performance data to port into Row acquisition, so, optionally, if the transmission rate obtained after the M-1 times transmission performance data acquisition is 0, state is obtained Modulus block 506 obtains the M-N times to the M-1 times corresponding transmission rate of transmission performance data acquisition, and calculates N number of transmission speed The average value of rate is used as in preceding rate, and N is greater than 1.If the transmission rate obtained after the M-1 times transmission performance data acquisition is not It is 0, then the transmission performance data that state acquisition module 506 directly acquires the M-1 times acquire corresponding transmission rate and are used as Preceding rate.
It is assumed that being currently that the 5th carries out the acquisition of transmission performance data, if abnormal determination module 504 is according to data acquisition When determining the acquisition of this data, data acquisition session is seized by high-priority task, then state acquisition module 506 can obtain The transmission rate for taking the acquisition of the 4th data corresponding is used as in preceding rate.If the transmission rate of the 4th is 0, state is obtained Module 506 it is available 2nd time, the 3rd time and the 4th data acquisition corresponding transmission rate, and averaged make For the 5th data acquisition when in preceding rate.
When state acquisition module 506 is got corresponding to currently time data acquisition after preceding rate, using smooth calculation Method obtains the current transmission rate in port according in preceding rate calculations.Optionally state acquisition module 506 can be according to following public affairs Formula calculates current transmission rate:
Wherein, SMFor current transmission rate, SM-1To be adjustment deviation in preceding rate k, value is equal toThe size of value is between 0~1, the tMIt is ' the finish time acquired for the M times data, described tM-1' the finish time acquired for the M-1 times data.AMFor the current actual flow in port, the value of the actual flow can be root It obtains, is also possible to according to when previous collected transmission performance data meter according to the optimization processing scheme introduced in embodiment one It obtains.Specifically, if in calculating port when current actual flow, abnormal determination module 504 determines transmission performance number According to exception, then state acquisition module 506 can be smooth to carrying out in preceding actual flow according to the scheme provided in previous embodiment Optimization processing, and then obtain the A when acquisition of this dataM.If abnormal determination module 504 determines that transmission performance data are normal, Then can A directly be calculated according to collected transmission performance data combination following formula in state acquisition module 506M:
AM=transmission total bytes+(the transmission port totalframes * frame gap)
It should be appreciated that for the actual flow of port sending direction, should according to the total bytes of sending direction with Totalframes is calculated, then should be according to the total joint number and totalframes of receiving direction for the actual flow of port receiving direction It is calculated.If abnormal determination module 504 determines current collected biography according to data acquisition results or data acquisition Defeated performance data is normal, is influenced whether inaccurate by data acquisition itself, then state acquisition module 506 can direct root The current state parameter of exit port is calculated according to collected transmission performance data.Such as the transmission rate current for port, it can To calculate according to the following formula:
In the present embodiment, no matter state acquisition module 506 is which kind of mode to have got the current transmission in port by The transmission rate can all be associated with port numbers and save by rate.It should be understood that should also when saving Associated storage can characterize the information of the acquisition serial number of data corresponding to the transmission rate.
Port status parameter obtaining device provided in an embodiment of the present invention is acquired in the transmission performance data to port Later, it can determine whether current collected transmission performance data receive number according to data acquisition results or data acquisition According to the influence of acquisition inaccuracy itself, objective judgement is carried out to data acquisition results.Determining current collected transmission performance Data are normal datas, when not acquired itself by data is influenced, directly calculate that obtain port current according to the data State parameter.When determining that collected transmission performance data have received the inaccurate influence of receipt acquisition itself, not directly It is calculated according to this transmission performance data for being unable to characterize port actual conditions and obtains the current state parameter in port, but according to The port optimizes processing in preceding state parameter, thus acquisition and the closer state parameter of actual conditions, and then be subsequent The network planning and maintenance more believable basis is provided, promote the quality of the network planning and maintenance.
