Embodiment
Embodiment one
The embodiment of the present invention provides a kind of message transmitting method, applied to equipment is sent, as shown in figure 1, should
Method can include：
Step 101, within the default testing time, to reflecting device send N0Individual basic test message.
Here, N0It is greater than 0 integer；
Step 102, receive the N that reflecting device is sent2Individual new basic test message.
Here, N2Less than or equal to N0
Step 103, when N being present4It is individual meet preparatory condition new basic test message when, to reflecting device
Send N4Individual new basic test message.
Here, the basic message carries recovered frequency, reflects in message the recovered frequency (Circular carried
Number) it is defined on Sequence in the throughput and packet loss message format of FRC2544 defineds
4 bytes are extended in filling field after Number, after extension, if the basic test in configuration information
Message length is 64 bytes, then without filling field, if as shown in Fig. 2 the basis in configuration information is surveyed
Examination message length is more than 64 bytes, then is filling field after Circular Number, such as Fig. 3 institutes
Show.
Specifically, by N2The recovered frequency of individual new basic test message subtracts 1, obtains new recovered frequency；
Judge whether new recovered frequency is more than 0；If N be present4The new recovered frequency of individual new basic test message
More than 0, then this N is sent to reflecting device4Individual new basic test message.That is this N4It is individual new
Basic test message is the new basic test message for meeting preparatory condition.
Further, it is special because the new basic test message that transmitting equipment receives is problematic message
It is not that its recovered frequency is changed into negative, it is, therefore, desirable to provide this row message, described by the N2Individual new base
The recovered frequency of plinth test packet subtracts 1, and obtaining new recovered frequency includes：Judge N2Individual new basis survey
Whether the recovered frequency for trying message is more than 0；If N3The recovered frequency of individual new basic test message is more than 0,
Then by N3The recovered frequency of individual new basic test message subtracts 1, obtains new recovered frequency.
So, within the default testing time, basic test message can back and forth be sent by sending equipment,
So, cyclic process is make use of, need not just increase FPGA and NP resources, basic test report can be passed through
Literary test equipment, therefore, even if FPGA and NP resources are inadequate, it can equally complete to test, so as to
Reach user's requirement.
In the present embodiment, to test under initial situation, the recovery number is default maximum recovery number, when
After the test period terminates, methods described also includes：Count the reception number of new basic test message；
According to reception number, N0Number is reclaimed with maximum, determines throughput and/or packet loss.
Specifically, the formula of throughput is identical with the formula of prior art, the present embodiment just no longer details,
The packet loss formula of packet loss is：Wherein, NAlwaysIt is to receive number, C*N0It is theoretic hair
Send number, N0It is transmission number first, C is maximum recovered frequency.
Basic test message is sent every time due in the cyclic process of transmission, sending equipment, can be received new
Basic test message, the basic test message and new basic test message are probably identical content,
Certain change is may have occurred, identifies that it is basic test with equipment is sent as long as not influenceing reflecting device
Message.
Further, the configuration information comprises at least basic test message length, test rate and the survey
Try the time, it is described to determine that basic test message includes according to the configuration information：
According to test rate, basic test message rate is calculated, the basic test message rate is the basis
The transmission rate of test packet or new basic test message；According to test rate and basic test message rate,
Determine the maximum recovered frequency.
Specifically, determine that the maximum recovered frequency includes：
So, maximum recovered frequency is：C=V/V0；Wherein, C is maximum recovered frequency；V is test speed
Rate；V0It is basic test message rate.
Wherein, V0Scope be (0, Vmax], VmaxBased on test packet constructing module can be generated
Maximum rate.Generally, in order to reduce the number that message circulates between transmitting terminal and reflection end, V0From Vmax
Start to search downwards, find a minimum integer C.
In the scheme, if V is less than Vmax, then V0=V, C=1.
Embodiment two
The embodiment of the present invention provides a kind of message transmitting method, and applied to message transfer system, the system includes
Equipment and reflecting device are sent, equipment is sent and comprises at least NP and FPGA.In test process, transmission is set
The standby and message transmission procedure of reflecting device is as shown in Fig. 4 arrow, and message can reuse, and Fig. 2 is only
It is exemplary illustration, specifically, as shown in Fig. 5 flow, this method can include：
Step 201, send the configuration information that equipment receives the packet loss for the RFC2544 tests that user inputs.
The configuration information includes message length, the test rate of the basic test message of configuration RFC2544 tests
And the testing time.
Step 202, FPGA determine basic test message according to configuration information.
FPGA calculates RFC2544 basic test message rate according to the test rate of configuration information,
And according to basic test message rate V0With test rate V, reflection message maximum recovered frequency C is calculated,
The C is：C=V/V0；
Wherein, V0Scope be (0, Vmax], VmaxTo send the maximum rate that equipment can be generated.
Generally, recovered frequency between equipment and reflecting device is being sent in order to reduce basic test message
(i.e. cycle-index), V0From VmaxStart to search downwards, find a minimum integer as C.
Preferably, if V is less than Vmax, then V=V0, C=1.
FPGA is according to V0With test packet length, construction basic test message rate is V0RFC2544
Basic test message, and increase recovered frequency in basic test message, original state recovered frequency is most
Big recovered frequency.
What deserves to be explained is in this programme, after basic test message module structure basic test message, it is necessary to
Statistical basis test packet number N0。
Step 203, NP are with V0Speed uniformly send N0Individual basic test message.
Step 204, reflecting device processing N1Individual basic test message, obtain new basic test message.
Here, due to sending N0Individual message, it not necessarily can just receive N0Individual message, therefore, N1It is
Less than or equal to N0。
Step 205, reflecting device send N to transmitting equipment1Individual new basic test message.
Here, the new basic test message number that NP is received is N2, due to sending N1Individual message, no
It necessarily can just receive N1Individual message, therefore, N2It is less than or equal to N1。
Step 206, NP judge N2Whether the recovered frequency in individual new basic test message is more than 0.If so,
Then perform step 207；If it is not, then perform step 214.
Here, NP can judge N one by one2Individual new basic test message, it can judge simultaneously parallel several
New basic test message.
Step 207, NP are by N3The recovered frequency of individual new basic test message subtracts 1, obtains new recovery time
Number.
N3It is the number of new basic test message of the recovered frequency more than 0.
Step 208, NP sentence whether new recovered frequency is more than 0.If so, then perform step 209；If it is not,
Then perform step 214.
Step 209, NP send N4Individual new basic test message.
The N4Individual new basic test message is the new basic test message that recovered frequency is more than 0.
Step 210, when sending equipment and determining testing time time-out, stop basic test message and send.
Step 211, NP stop basic test message and received after preset duration.
So, ensure all to reflect from the test packet that transmission equipment is sent, then stop receiving instead
Penetrate message and statistics reflection message.
Step 212, the reception number for sending device statistics basic test message.
Step 213, equipment is sent according to number and maximum recovered frequency is received, calculate packet loss.
Here, the packet loss formula of packet loss is：Wherein, NAlwaysIt is to receive number, C*N0It is
Theoretic transmission number, N0It is transmission number first, C is maximum recovered frequency.
Step 214, abandon new basic test message.
