Embodiment 1: as shown in Figure 1, the method and apparatus that a kind of ethernet test instrument high-precision flow percentage generates,
More particularly to a kind of ethernet traffic sending control method and device based on optical transport.It is accurate according to the flow percentage of setting
The transmission of ethernet data frame is controlled, with this test network reliability.
A kind of method that ethernet test instrument high-precision flow percentage generates, comprising:
Step 1 accurately controls constant flow rate, it is assumed that Ethernet can uniformly send data frame by byte, be in bandwidth
10000B/s, flow 1000B/s, in the case that frame length is 256 bytes, the byte that average each clock cycle sends is
1000/10000=0.1B.The number is known as frame percentage.Added up frame percentage until being greater than in each clock cycle or
A data frame is sent when equal to frame length 256B.Since interval 256B sends data frame, frame length 256B is referred to as frame period at this time.
If frame period is less than frame percentage, illustrate to be less than theoretical sending value, frame percentage in this moment practical sending value
The frame number that sends is needed than being exactly divided by frame period, then subtract once obtaining of having sent is exactly frame number.Frame number is big
In 0, continue to send data frame.Frame percentage is referred to as frame remainder, less than one number of frame remainder divided by the remainder that frame period obtains
It is added to according to frame and participates in calculating next time.
So frame percentage calculation are as follows: frame percentage=flow percentage × bus bit wide × 15625.Data frame hair
Send interval calculation mode are as follows: frame period=(frame length+FCS+IPG (12byte)+PREAMBLE_SOF (8byte)) × 15625.Always
Line bit wide indicates the data that can be handled simultaneously each clock cycle, present invention 64bit.Make to calculate more to reduce error
Accurately and conveniently, for each parameter multiplied by a biggish integer 15625 to eliminate decimal.
Frame number calculation are as follows: frame number=(frame percentage/frame period) -1.Frame remainder calculation are as follows: frame remainder
=frame percentage % frame period.If frame number is greater than 1, the data frame of corresponding number is sent.Frame remainder is added to frame percentage
Than being calculated for the clock cycle next time.
Step 2 includes purpose MAC for ethernet data frame, source MAC, 802.1Q label (optional), ethernet type,
Load, cyclic redundancy check etc..
It should be noted that Ethernet data transmits on network medium needs to follow certain mechanism, wherein CSMA/CD
Media access control mechanism has arranged Ethernet when transmitting data, need to wait between two frames a frame gap time (IFG or
IPG), while ethernet data frame also needs the preamble field of 7byte and the delimiter of 1byte in transmission.
Therefore Ethernet data consists of the following parts in transmission process: 7byte (leading)+1byte (is delimited
Symbol)+ethernet data frame+4byte (FCS verification)+12byte (IPG).
It include link layer protocol frame head, network layer protocol frame head, transport layer protocol frame head for ethernet data frame load

Step 3, flow refer to the bit or byte number of Ethernet transmission per second.Flow percentage refers to that flow accounts for bandwidth
Percentage.Such as Ethernet bandwidth 100Gbps, flow is 10Gbps, then flow percentage is 10Gbps/100Gbps=
0.1Gbps。
Step 4, for multiple data flows the case where, refer to synchronization send 1+N data frame.It is equivalent to each
The byte sent in clock cycle is 1+N times.So should be multiplied by number of data streams when calculating frame percentage: frame percentage=stream
Measure percentage × number of data streams × bus bit wide × 15625.Other parameters are without modification.
Step 5, the Ethernet for 100Gbps, rate are 100000Mbps.It is to parallel data processing bit wide
512bit, bus frequency are 322.265625MHz.Bus Speed be 322.265625 (MHz) × 512 (bit)=
165000Mbps.Bus Speed is 1.65 times of transmission rate.So when calculating frame period multiplied by 1.65, it is small in order not to occur
Number, multiplied by 4 when calculating.The Ethernet of 10G included below for 10G, parallel data processing bit wide can be 64bit,
32bit, 16bit, 8bit and 4bit.The rate and network transmission speed of bus are consistent, and are not needed multiplied by any multiple.
So parameter is calculated as when test 100G Ethernet, frame percentage=flow percentage × number of data streams × total
Line bit wide × 15625 × 4.Data frame sends interval calculation are as follows: frame period=(frame length+FCS+IPG (12byte)+PREAMBLE_
SOF(8byte))×15625×1.65×4。
Step 6 recycles execution according to above step, and data frame is uniformly and stable with one in regular hour length
Flow send.Measurement accuracy can reach: 0.001%~100.000%.

Data frame sends control module and obtains data flow, frame length, and flow percentage is used to calculate what control data frame was sent
Parameters calculate as follows:
Frame period=(526+4+12+8) x15625x1.65x4 is rounded i.e. 56718750.
Frame percentage=0.1 (10%) x15625x256 (total fluxion) x64x4, i.e., 102400000.
Start cycle control logic, frame percentage is accumulated as 102400000 for the first time.The value is greater than frame period
56718750, log-on data frame sending module sends data frame.
Because frame period is less than frame percentage, calculate: frame number=(102400000/56718750) -1, i.e., 0；No
It needs to send data frame again.Frame remainder=102400000%56718750, i.e., 45681250.Frame remainder is added to frame percentage
Than 102400000+45681250.
Execution recycles next time, and frame percentage is accumulated as 102400000+45681250=148081250 for the second time.The value
Greater than frame period 56718750, log-on data frame sending module sends data frame.
Because frame period is less than frame percentage, calculate: frame number=(148081250/56718750) -1, i.e., 1；It needs
Retransmit a data frame.Frame remainder=148081250%56718750, i.e., 34643750.Frame remainder is added to frame percentage
Than 102400000+34643750.
