Connection method between examination port is attached.Furthermore it is possible to understand, Fig. 1 is route as just the signal to routing device
The specific port number of equipment and the specific port tested are not intended as the restriction in the present embodiment.
First embodiment
A kind of loop testing method is present embodiments provided, Fig. 2 is referred to, this method includes：
Step S110：Before test data is sent or in transmission process, the first test port 110 of control is tested to second
Port 120 sends background data message.
Test data is the data for the first test port 110 and second port receive and dispatch test, the test
The transmissions of data, receive and analysis is not limited in this embodiment, can with the prior art by test data to route
The loopback test of equipment is consistent.
If the first test port 110 of control sends background data report to the second test port 120 before test data is sent
And then text, then after test data transmission, can send background data message, send test data with sending background data report
The time difference of text does not limit in the present embodiment.
Simply, in the present embodiment, the survey for the first test port 110 of analysis and the performance of the second test port 120
Data are tried, preferably background data message is in the measurement circuit where the first test port 110 and the second test port 120
Formed after linear speed, the test data of transmitting-receiving, to be used in the survey of the analysis performance of the first test port 110 and second port performance
Examination data are the test data received and dispatched in measurement circuit under elevated pressures.
In addition, background data message in the present embodiment and test data message are different messages, and the background data report
The existing various messages of Wen Weiyu have the message of different characteristic, that is to say, that the background data message is with identity
Message, to be different from message of the prior art, enable the first test port 110 and the second test port 120 to background
Data message is correctly recognized.The background data message can be constructed by the first test port 110, and message can be wide
Report is literary or is promiscuous mode by two test port configurations, then chooses unicast message, it is most important that carry on the back this
Scape data message is configured to the message for having different characteristic with existing various messages, can before being tested by order or
Code configuration is good.
In the present embodiment, specific identifier can be carried in background data message to identify it as background data message body
Part.Specifically, the specific identifier can carry the EtherType field in background data message, the EtherType field is located at
After source MAC, with two byte bit wides.It is preferred that, the occurrence of the specific identifier in background data message is existing
In agreement and untapped field value, such as 0x9527.Certainly, the tool of field where the specific identifier carried in background data message
Body position, specific bit wide and occurrence are not limited in the present embodiment, as long as can be used to identify background data message difference
In the routing device other messages involved in test process.
Can be 1024 bytes to any between 2048 bytes in addition, background data message is the long message of regular length
The message of length, certainly, its specific length are not also limited in the present embodiment, can be according to the background data in measurement circuit
Background data packet sending and receiving cycle, software processing speed and equipment storage capacity that the transmitting-receiving of message is formed required for linear speed etc.
Factor is together decided on.For example, the length selection of background data message is 1518 bytes.
Step S120：When second test port 120 receives the background data message, second test is controlled
The background data message is sent to first test port 110 by port 120.
Step S130：When first test port 110 receives the background data message, first test is controlled
The background data message is sent to second test port 120 by port 110 again,
Residing background data message is in the survey including first test port 110 and second test port 120
Try the data flow of formation linear speed on circuit.
When the second test port 120 receives the background data message of the first test port 110 transmission, then by the background number
The first test port 110 is returned to according to message, the first test port 110 receives the background number of the second test port 120 return
The second test port 120 is returned to according to message, and by the background data message, makes background data message in the first test port
110 and second come and go between test port 120 and send, to form the data flow for reaching linear speed in measurement circuit.
Wherein, because background data message is the message with identity, then report is received in the first test port 110
Wen Shi, can determine whether the message received is background data message, if so, then by the background number according to the analysis to message
The second test port 120 is sent to according to message.Likewise, when the second test port 120 receives message, can also be according to right
The analysis of the message received is determined whether for background data message, if so, the background data message then is sent into the first survey
Try port 110.
For example, the EtherType field value in background data message is 0x9527, then the first test port 110 or second is surveyed
Examination port 120 is received after message, and the EtherType field in message is parsed, once EtherType field etc. in message
In 0x9527, then it is assumed that the message is background data message, is directly sent from this test port.
In addition, the data flow to form linear speed on measurement circuit, the transmission rate to background data message is more than or waited
Speed needed for the data flow of linear speed is formed on measurement circuit, that is to say, that small to the transmission cycle of background data message
The back of the body is sent in or equal to the time cycle that can be formed on measurement circuit needed for the data flow of linear speed, i.e. the first test port 110
The time difference that the time of scape data message returns to the background data message with the second test port 120 is less than or equal to week time
Phase.For example, the first test port 110 sends background data message, the second test lead in the very first time to the second test port 120
Mouthfuls 120 receive after the background data message and to return to the background data message, first to the first test port 110 in the second time
Test port 110 is after the background data message of the second test port 120 return is received, in the 3rd time again to the second test
Port 120 send background data message, then the time difference between the very first time and the second time should be less than or equal to the above-mentioned time
Cycle, the time difference between the second time and the 3rd time should be less than or equal to the above-mentioned time cycle.
Specifically, because the corresponding calculation formula of linear speed is：Line speed (bits)=(message length+fixed overhead) *
Message number * 8 per second, wherein, fixed overhead is usually 20, and message length and fixed overhead unit are byte, and 8 represent one
Individual 8 bit of byte.Linear speed is then if desired formed on measurement circuit, then in the first test port 110 and the second test port
Period of time T=((message length+fixed overhead) * 8)/message number per second that message is sent on measurement circuit where 120.
By size be the background data messages of 1518 bytes, exemplified by the test port of gigabit, if desired on measurement circuit
Linear speed is formed, the message number x=1000000000/ ((1518+20) * 8) of each second then needs the message number sent each second
Mesh x=81274.4pps (packet per second), then under gigabit speed, the background data message of 1518 bytes is sent
Maximum period of time be T=1/81274.4pps=1.23*10(-5)S, the maximum period of time is the shape on measurement circuit
Into the time cycle required for linear speed, message send the cycle be less than or equal to the maximum period of time can on measurement circuit shape
Into linear speed.
Because when ether interface carries out loopback test, the length of whole ether physical circuit is shorter, is generally averaged
In 30CM or so, according to the transmission rate of the Ethernet message light velocity on the line, the transmission time of the physical circuit of 30CM length is
0.8*10-10Second, i.e., in loopback test, transmission time of the message on physical circuit is extremely short, can be ignored, then and first
The test port 120 of test port 110 and second send background data message during, as long as send the cycle be less than it is above-mentioned most
The big time cycle, then linear speed can be formed on measurement circuit.And existing communication processor on measurement circuit for forming line
The time cycle of speed can be easily met, therefore, by background data message in the first test port 110 and the second test lead
Round transmission between mouth 120 forms linear speed data flow and easily realized.
In the present embodiment, the data flow of linear speed, two test leads are formed on measurement circuit by background data message
Mouth is in high pressure test mode, therefore, is formed on measurement circuit after the data flow of linear speed, the test data on measurement circuit
Can be used for the test port of the test analysis to test port, i.e., two can carry out the transmitting-receiving of normal test data message,
Carry out corresponding test statisticses and the handling process such as test result is reported.Under high pressure test mode, pass through test data
Test result to test port is more reliable and more stable, more accurately.Relative to prior art, make the ring of original test port
The test pressure for returning test is greatly improved, so as to enhance the proof strength of production test, improves factory inspection and acceptance standard,
Positive role is brought for the product control of product.
Also, in the method that the present embodiment is provided, the speed of ether physical circuit is make use of as " back pressure ", it is not necessary to drive
The dynamic batch message that carries out is configured to realize background data stream, and addition is needed due to having sent more than linear speed without consideration
Fault-tolerant processing；Also, it is small to memory cost, due to not needing the structure background data message of batch, avoid the need in substantial amounts of
Deposit expense, it is only necessary to which special message this to background data message is reprocessed.
