Description
The method and system of the bit error rate is measured in a kind of ether transmission net
Technical field
The present invention relates to a kind of method and system for measuring the bit error rate, the method and system of the bit error rate is measured in more particularly to a kind of ether transmission net (Ethernet over Transport, EoT).Background technology
With developing rapidly for data service, how the transmission data service of high efficient and reliable turns into the problem that industry is paid close attention to, and therefore EoT concept is also proposed by each operator, producer and standardization body.
QoS (service shield amounts of the EoT for data service, Quality of Service) and 0AM (operations, management and maintenance, Operation, administration and maintenance) higher requirement is proposed, this is also the part that traditional ethernet compares shortcoming.
An important index is exactly the bit error rate of network in QoS, due to the characteristic of packet network, as long as it is invalid that a frame has a bit mistake to this may result in full frames of data, therefore the bit error rate and packet loss are to be mutually related in packet network, in the network for the packet for having regular length（Such as ATM) in, packet loss can directly converse the bit error rate.
Current ethernet device is also often, by exclusive data tester, to be measured under specified several specific frame lengths, and now the bit error rate and Lost bag rates are also directly to convert, thus equipment it is general it is nominal be its Lost bag rate.The height of Lost bag rates, which can also typically reflect that the actual motion stability and reliability Wang Luo Lost bags rate of network rise, can bring the loss of user's actual available bandwidth, it is high for requirement of real-time, the media stream business such as voice, video of retransmission mechanism is filled, the bandwidth of loss will appear as the decline that user obtains service quality.
But EoT networks are based on ethernet technology, Ethernet is in units of frame, length can be from 64 bytes to 1522 even more big bytes, now can not directly it be converted between the size and the bit error rate of packet loss, a kind of simplest situation, two networks of A, B all deliver each 100 of the frame of 64 bytes and 1518 bytes, A Wang Luo Lost have lost the frame of 64 bytes, B Wang Luo Lost have lost the frame of 1518 bytes, Ta Lost bag rates are the same, all it is 0.5%, but the bit error rate differs nearly 24 times.In the application such as special line is rented, because the length of frame is not unalterable, the band of actual loss can not be reflected by only providing packet loss
It is wide, when being related to streaming media service, because the frame of loss will not be transmitted again, the bit error rate brought during the identical packet loss of different frame length is differed, and the size of the bit error rate is just directly related with the mosaic of video and the magnitude of audio noise, therefore user is even more it should be understood that the bit error rate of network and not exclusively packet loss.The content of the invention

The embodiment of the present invention realizes the measurement of the bit error rate by the way of specific OAM frames are inserted in former data frame.The byte number (TxBC) that source is sent in a period of time is transmitted by the OAM frames between source and egress, egress is by counting invalidation word joint number（Containing loss and erroneous frame byte）The network bit error rate can be drawn with after total transmission byte number.
The present invention is described in further detail with reference to the accompanying drawings and examples.
It is the system that the present embodiment is made up of source and egress shown in Fig. 1, wherein：
Source includes：
OAM frame generators（OAM Generator) 1, the statistical value TxBC for receiving the transmission byte number that sending side counter is provided, generation includes the OAM frames of the value, is then periodically inserted into error rate test OAM frames to sending side；
Sending side byte counter（TxByteCounter) 2, TxBC is provided for being counted to the byte number transmitted by sending side, and to OAM frame generators, the error rate test OAM* of insertion can be disregarded during counting;
Sending side（Egress) 3, for sending data frame by EoT nets；
Egress includes：
OAM frame analyzers（OAM Analyzer) 4, error rate test OAM frames are extracted from receiving side 6, its internal TxBC count value are explained, and latch the effective word joint number RxBC of receiving side byte counter statistics;The difference that byte number TxBC is sent in the two difference OAM frames received is calculated, subtracts the effective word joint number RxBC received between the two OAM frames, obtains the byte number lost between the two OAM frames；Yong the Lost byte numbers lost divided by send byte in the two OAM frames:TxBC difference obtains the bit error rate.
Receiving side byte counter（RxByteCounter) 5, the effective word joint number for being received to receiving side joint is counted, and can disregard the OAM frames received；
Receiving side（Ingress) 6, the data frame for receiving EoT net transmission.
In Fig. 1, source also has receiving side, and egress also has sending side.What be confused source and egress were distinguished just for specific Ethernet transmission services.
The method that the bit error rate is measured in the present embodiment ether transmission net comprises the following steps:.
Bu Sudden mono-：When source is to egress transmission Ethernet service, the byte number that statistics is sent is TxByteCounter (Fig. 1,2)；Egress then counts the effective word joint number being currently received（The byte number of the specific OAM frames of source insertion can be disregarded）For RxByteCounter (Fig. 1,5)；Effective word joint number is that egress verification is correct（Including the frame corrected by mechanism for correcting errors）Data frame total amount of byte, because the reasons such as error code cause the not accrued effective byte number of frame that will be stripped.
Step 2：After a period of time, source treats that the data frame sent is sent, and is immediately inserted into the statistical value TxBC that the content carried in a 0AM frame, frame is current TxByteCounter;
The OAM frames are specific ethernet frame, can pass through ethernet type domain（Type Field) or the method such as particular source or target MAC (Media Access Control) address identify the frame, the frame is produced by being responsible for the source that the bit error rate is detected, is peeled off by egress, frame internal form is not limited, as long as byte counter can be transmitted；Above-mentioned a period of time does not have specific limitation, its purpose is to reduce the quantity of OAM frames transmission, it is to avoid the excessive network bandwidth be taken, so it can be a fixed cycle time, it can also be the time or time of artificial operating interval etc. twice for sending certain amount frame.Byte count value in cycle T and OAM frames（TxBC or RxBC) there is the relation mutually constrained, in n*T, (n is the number of times that system allows OAM frames continuously to lose）In cycle, byte count value TxBC and RxBC should not have the possibility for returning to initial value.
Step 3：When the egress mat woven of fine bamboo strips once receives OAM frames, RxByteCounter current statistic value RxBC are latched, and extract the preservation of the TxBC values in OAM frames；Egress is received after follow-up OAM frames, and the two OAM interframe RxBC difference is subtracted with the difference of TxBC in two different OAM*, you can obtain the byte number of this period Nei Lost mistakes；Further, it is that can obtain the bit error rate with the difference of TxBC in the byte number of loss divided by the two OAM frames.
Two different OAM frames can be that the data frame sent between adjacent OAM frames or non-conterminous OAM frames, but the two OAM frames should be permitted several maximums less than RxBC or TxBC bytes.'
In difference operation, when minuend is less than subtrahend, illustrates that RxBC or TxBC bytes are counted and overflowed, complement code should be used or be added negative result with BC maximum.
In bilateral network, RxBC and TxBC value by OAM frames can be passed back to source by egress, and source can calculate the bit error rate of egress reception using the algorithm same with the 3rd step, as the distal end performance of oneself（Sending side performance）Report webmaster.It is illustrated below with an application example.There is an Ethernet service for needing to monitor the bit error rate between two websites as shown in Figure 2, website A websites B, the Fast Ethernet port of B websites is sent to from Ethernet FE (Fast Ethernet) port of A websites.
A websites send an OAM frame per 100ms to B points, and A points and B points use the transmitting-receiving byte counter of 4 bytes.
Handling process is as follows：
A points start a sending side byte counter TxByteCounter, count the byte number sent, often send a byte, and counter TxByteCounter adds 1;B points start a receiving side byte counter RxByteCounter, ' after effective packet is received, its frame length is included in RxByteCounter;
Start error rate test, A points insert an OAM frame, and TxBC is TxByteCounter currencys
(such as： 20000 ) ；After first 100ms cycle reaches, A points are inserted into a 0AM frame, and new TxBC is TxByteCounter currencys（Such as：30000), represent that this time 100ms cycles A points have sent 10000 bytes altogether.
B points receive first 0AM frame（Fig. 3, T1) when, it is RxBCl (such as 10000) to latch RxByteCounter currencys, and the TxBC extracted in 0AM frames is recorded as TxBC 1 (such as 20000);
B points receive second 0AM frame（Fig. 3, T2) after, it is RxBC2 (such as 19900) to latch RxByteCounter currencys, and extracts 0AM1!1TxBC in chastity is recorded as TxBC2 (such as 30000)；So the byte number of loss is in this time interval：（TxBC2-TxBCl)-(RxBC2-RxBCl)=(30000-20000)-(19900-10000)=100, the bit error rate is 1001 (30000-20000)=1%.
With the arrival in 100ms cycles, A points send 0AM frames one by one, and B points receive, counted and calculated using above-mentioned similar approach one by one, it is possible to obtain A points to the bit error rate number Ju of B this each period of link of point.
If in difference operation, when minuend is less than subtrahend, illustrating that RxBC or TxBC bytes are counted and having overflowed, complement code should be used or be added negative result with RxBC or TxBC maximum.
In bilateral network, RxBC and TxBC value can be led to ± OAM j and be passed back to sending side by receiving side, and sending side can calculate the bit error rate of receiving side reception using same algorithm, as the distal end performance of oneself（Sending side performance）Report webmaster.
The purpose for having reached the test real network bit error rate by this method can be seen above, can be used for the real-time monitoring of network quality.
Industrial applicibility
Using method and system of the present invention, overcoming can not be accurate in EoT networks in the prior art
The bit error rate is measured, the situation of packet loss can only be measured, and ^ I can not reflect the bandwidth of actual loss according to packet loss.The present invention can On-line sampling system EoT networks real bit error rate situation, measurement result is accurate, in time, data by equipment gather after can record and show on webmaster, facilitate engineer applied and network monitoring.
