Part is realized, current time stamp is stamped for the detection messages field that directly specified Offsets inside message.And inciting somebody to action
When detection messages are sent to the entrance of the message passage to be detected, record current time is used as the detection
The initial time stamp of message.
While the step S10 is performed, following steps are performed：
Current time is recorded as the termination timestamp of the detection messages.
When obtaining detection messages in the outlet of message passage to be detected, record current time is used as the inspection
The termination timestamp of text is observed and predicted, finally, the detection messages are exactly to be carried along into the message to be detected to lead to
The start time point in road and the detection messages at the termination time point come out from the message passage to be detected.
In the present embodiment, the mode for obtaining detection messages in the outlet of message passage to be detected includes：Together
When obtain a detection messages in the outlet of each message passage to be detected, or to be checked observe and predict at each simultaneously
The outlet of literary passage obtains multiple detection messages successively；Or going out in each message passage to be detected successively
Mouthful a detection messages are obtained, or in the outlet of each message passage to be detected obtain multiple inspections successively successively
Observe and predict text.
Step S20, parse initial time stamp of the detection messages in the message passage to be detected and
Terminate timestamp；
In the present embodiment, after getting detection messages in the outlet from message passage to be detected, into association
The detection messages of acquisition are parsed in view stack, the message passage to be detected in the present embodiment can be with
It is expressed as CPU (Central Processing Unit, central processing unit) to line up, also referred to as passage team
Row, and the protocol stack can represent CPU protocol stacks, wherein, the message passage of the CPU protocol stacks
Just there are 48 message passages, equivalent to there are 48 cpu queues.
In the present embodiment, when getting detection messages in the message passage to be detected, you can it is determined that
The gap marker of message passage to be detected, i.e., come out, then the report in detection messages in which message passage
Literary passage is message passage to be detected, and obtains the gap marker of the message passage to be detected；Or
When person gets detection messages in the message passage to be detected, the passage mark that analysis detection messages are carried
Know, to determine message passage to be detected.And after detection messages are got, the inspection to acquisition
Observe and predict text to be parsed, to parse the timestamp of detection messages, the timestamp is the detection messages
Initial time stamp and termination timestamp in corresponding message passage.Specifically passing through DMA
((Direct Memory Access, direct memory access) mode is extracted detection messages from message passage
Into CPU protocol stacks (also referred to as CPU internal memories) in order to carry out analytical Calculation, in bottom layer realization
Be taken in cpu queue caching in have detection messages, then by DMA by detection messages from message passage answer
Make CPU region of memorys and trigger interrupt signal, in order to parse the initial time stamp of the detection messages
With termination timestamp.
Step S30, based on initial time stamp of the detection messages in the message passage to be detected and end
Only timestamp, calculates time delay of the detection messages in the message passage to be detected；
It is determined that after the initial time stamp or termination timestamp of detection messages, being existed based on the detection messages
Initial time stamp and termination timestamp in the message passage to be detected, you can calculate the detection messages
Time delay in the message passage to be detected, that is, the time for terminating timestamp is subtracted into initial time
At the time point of stamp, you can obtain the time difference, the time difference is the detection messages to be checked observes and predicts described
Time delay in literary passage.Specifically, read after detection messages content is got from detection messages specified location
Take RxTimeStamp and TxTimeStamp time stamps.Both by delay time=TxTimeStamp-
RxTimeStamp formula can complete time-delay calculation.And the gap marker of message passage then directly passes through
The parsing of channelNo fields is drawn.Alternatively, it is also possible to carry message passage by bottom DMA mechanism
Gap marker is into CPU internal memories, to be read by software module.In the present embodiment only with analytic message
Mode is obtained.
Step S40, using the time delay of calculating as the message passage to be detected average delay.
Detection messages are being calculated after the time delay of the message passage to be detected, by the time delay of calculating
As the average delay of the message passage to be detected, specifically, obtained in the outlet of message passage to be detected
When the detection messages got are one, the time delay of calculating is regard as the flat of the message passage to be detected
Equal time delay；And the detection messages got in the outlet of message passage to be detected for it is multiple when, treated described
The time delay of each detection messages carries out phase adduction and averaged in detection messages passage, and by the average value
It is that can obtain each to be checked to observe and predict according to this mode as the average delay of the message passage to be detected
The average delay of literary passage.And the calculation of the average delay of message passage to be detected can also be with difference
Cycle is calculated：Time delay mean value computation for example is carried out by 5 seconds, 15 seconds, 30 seconds of the cycle, calculates public
Formula is as follows：Avg=(T1+T2+Tn)/period, wherein, Tn is n-th in a detection cycle
The time delay value of detection messages, being averaged for each message passage to be detected can be calculated according to this calculation
Time delay.
To be best understood from this programme, citing application scenarios are as follows：
First, detection messages are constructed, the form of detection messages is：
Dstmac：
Data:0x00d0d0ffffff
Mask:0xffffffffffff
Ethertype:
Data:0x8875
Mask:0xffff
Channel No:
Data:xx
Mask:0xff
After detection messages construction complete, specify Action actions as follows:
Copytocpu
CosqCpuNew
Drop
Wherein, Copytocpu actions are responsible for detection messages to copy to entering for the i.e. message passage of cpu port
Mouthful；CosqCpuNew acts the cpu port queue i.e. message entered for specifying detection messages to need and led to
The channel number of road queue；Drop actions represent discarding detection messages, and the action is in message Air conduct measurement
After the completion of.
The detection method of message passage proposed by the present invention, first obtains inspection in the outlet of message passage to be detected
Observe and predict text, then parse initial time stamp of the detection messages in the message passage to be detected and
Terminate timestamp, then initial time stamp based on the detection messages in the message passage to be detected and
Timestamp is terminated, time delay of the detection messages in the message passage to be detected is calculated, finally will meter
Calculate the time delay as the message passage to be detected average delay, rather than detection the network equipment
Message passage when, can only to the various functions of the network equipment, test analysis is to investigate failure one by one, most
End just can determine that ductility goes wrong when being, the present invention is by analyzing detection messages, to determine report
The time delay of literary passage, improves the efficiency to message Air conduct measurement.
Further, in order to improve the detection flexibility of message passage, this hair is proposed based on first embodiment
The second embodiment of the detection method of contract quotation text passage, in the present embodiment, reference picture 2, the step S10
Afterwards, the detection method of the message passage also includes：
Step S50, if in prefixed time interval, being got in the outlet of the message passage to be detected multiple
Detection messages, then count the number of the detection messages got；
Step S60, the message passage to be detected in the prefixed time interval is determined according to the number of statistics
Message cumulative amount.
In the present embodiment, if in prefixed time interval, being obtained in the outlet of the message passage to be detected
To multiple detection messages, then the number of the detection messages got is counted, be then according to the number of statistics
It can determine that the message cumulative amount of the message passage to be detected in the prefixed time interval.Wherein, it is described
Prefixed time interval is configured according to the specific time, could be arranged to 30 seconds, 1 minute, 10 minutes or
30 minutes etc., finally, the message cumulative amount of the message passage to be detected to be checked is observed and predicted as described
The testing result of literary passage.Specifically, calculation is as follows：Avg=Count/period, wherein, count
It is the cumulative number of the detection messages of message channel transfer to be detected in a measurement period.
Further, can also according to message passage to be detected described in periodic statistics detection messages number,
The detection messages of message passage to be detected are counted every prefixed time interval.
In the present embodiment, not only using testing result of the time delay as message passage, also by cumulative amount
As the testing result of message passage, the flexibility of message Air conduct measurement is improved.
Further, in order to improve the detection flexibility of message passage, this hair is proposed based on second embodiment
The 3rd embodiment of the detection method of contract quotation text passage, in the present embodiment, reference picture 3, when timing performs institute
State in the step of the outlet acquisition detection messages of message passage to be detected, after the step S60, institute
Stating the detection method of message passage also includes：
Step S70, by the message cumulative amount of the message passage to be detected and a upper prefixed time interval
The message cumulative amount of the message passage to be detected is compared；
Step S80, in the message cumulative amount and a upper prefixed time interval of the message passage to be detected
When the message cumulative amount of the message passage to be detected is equal, the message passage to be detected is emptied
Reset.
In the present embodiment, will be described to be detected it is determined that after the cumulative amount of the message passage to be detected
The message of the message cumulative amount of message passage and the message passage to be detected in a upper prefixed time interval
Cumulative amount is compared, if comparison result is identical, illustrates that detection messages are in institute in this prefixed time interval
State no in passage to be detected transmit successfully, you can represent that the message passage to be detected blocks completely
, just cause detection messages to send failure, now, the message passage to be detected carried out emptying reset,
Problem is solved equivalent to by resetting related bottom module.
Specifically, when the sending method for constructing message is different, the detection of message passage cumulative amount to be detected
Mode also includes following two situations：
1) in the case of sending detection messages for periodicity, then regularly read in message passage to be detected and examine
Observe and predict the quantity of text, and by quantity and the message passage last time to be detected of the detection messages of this reading
Whether the quantity of the detection messages of reading is compared, to judge the message passage to be detected in effective
Working condition；Illustrate that the message channels operation to be detected is normal if statistical counting has cumulative change,
Self- recoverage processing need not be carried out, it is notable that in above-mentioned Timing Processing, timing cycle is big
In the transmission cycle of detection messages, the number for obtaining detection messages statistics under normal circumstances so just can guarantee that
After value is accumulated counts；If statistical counting does not change, illustrate that the message passage to be detected is in mistake
Effect state, i.e., described message channel block to be detected is then now carried out to the message passage to be detected
Reset is emptied to recover the message passage to be detected.
2) when sending detection messages on demand, if the cumulative meter of front and rear twi-read detection messages
Number is unchanged, it is necessary to which further discriminating between current network device is in idle condition or message passage occur
Failure fails to detection messages, under detected status on demand, the transmission of detection trigger message, and is sending
After the completion of re-read counting messages counting；If global statistics, which are counted, cumulative change, illustrate described treat
Detection messages channels operation is normal, without self- recoverage processing；If passing through message under detected status on demand
The statistical counting of passage is judged to produce failure, equally the message passage to be detected is carried out emptying reset
To recover the message passage to be detected.
In the present embodiment, if it is 1 second that detection messages, which send the cycle, then determined in fault detect self- recoverage
In plan processing, if can not receive detection messages or detection messages in 3 seconds, to count cumulative statistics constant, recognizes
Failure is produced for the message passage to be detected, the message passage to be detected can be carried out emptying reset,
To ensure that the message passage to be detected does not produce prolonged detection messages loss situation；Either pass through
Switching message passage simultaneously recovers original message passage using bottom hardware modular manner is resetted.
Further, it is real based on first, second or third in order to improve the detection flexibility of message passage
Apply the fourth embodiment that example proposes the detection method of message passage of the present invention, reference picture 4, in the present embodiment,
After the step S40, the detection method of the message passage also includes：
Step S90, the average delay of the message passage to be detected is compared with default time delay；
Step S100, is delayed higher than when presetting in the average delay of the message passage to be detected, improves institute
State the priority of message passage to be detected.
In the present embodiment, the average delay of the message passage to be detected is obtained first；Then will be described
Average delay is compared with default time delay；It is if being currently able to meet protocol requirement, i.e., described to be detected
The average delay of message passage is delayed less than or equal to when presetting, and illustrates the message of message channel transfer
Speed, reaches and require that, is not in larger delay, does not process now；If described treat
The average delay of detection messages passage is higher than default time delay, illustrates that the when ductility of message passage is larger,
Be probably passage message transmissions speed it is slower, it is undesirable, then now improve the message to be detected
The priority of passage, should during in order to next transmission protocol message to strengthen the performance of the message passage
The when ductility of message passage can be reduced.
Further, more excellent message passage can also be searched according to different policy requirements, specifically, can
To be to extract the stage in agreement to specify the message passage for needing to change, to complete the adaptive excellent of message passage
Change, during in order to network equipment transmission protocol message where the message passage, first using the network
The high message passage of priority is used as protocol massages message passage to be sent in equipment.
Further, it is when presetting using average delay and protocol requirement highest time delay thresholding in the present embodiment
Prolong and be compared.If the average delay of current message passage>Protocol requirement time delay highest time delay thresholding, then
Higher priority message passage is begun look in current scheduling node, if finding high prior message passage
Delay performance<Protocol requirement time delay highest thresholding, the detection messages for further reading current message passage add up
The detection messages cumulative amount of preferred message passage is measured and treated, message passage to be selected is estimated in cumulative amount ratio
Prediction delay performance.If this prediction delay performance is more than current transmission protocol requirement time delay, successive
Higher priority message passage is searched until limit priority message passage.If highest priority packet
Passage, which remains unchanged, to be met, then does not do adaptive optimization action.
In the present embodiment, because application scenarios are that the network equipment possesses multiple message passages, and each
Message passage carries out self-adapting detecting and the process of processing according to detection messages, and arrives CPU protocol stacks
Message passage has 48 cpu queues, therefore, and queue scheduling is scheduled using 4 grades of scheduling modes.
In the present invention, self-adapting detecting and the adaptive decision-making processing of message passage are realized, is improved
The redundancy protecting of detection messages treatment efficiency in the network device and detection messages treatment channel, is improved
Network robustness and fault-tolerant ability.Particularly under high traffic, complex network scene, efficiently solve
