Referring to Fig. 1, for a kind of schematic diagram of network quality detecting system shown in the embodiment of the present invention.The system includes two
Individual terminal device PC1 and PC2, two routing devices R1 and R2.If service message is sent to PC2 from PC1, R1 is access device,
R2 is outlet device, detects the network quality from access device to outlet device.
Before testing, access device and outlet device are configured, specifies and which Business Stream is network matter is carried out based on
Amount detection, for example, five-tuple information (source IP address, source port number, purpose IP address, destination slogan, agreement by Business Stream
Type) be added in the ACL (Access Control List, accesses control list) of access device and outlet device, based on
Service message with the ACL carries out network quality detection, meanwhile, specify access device to dye service message, wherein, dye
Color refers to be identified a certain Q-character of service message, to be different from other service messages.
In addition, the clock of access device and outlet device is synchronous in the present invention, dyeing cycle is synchronous, for example, access device
The initial time of current dyeing cycle is 8:30:10, then the initial time of the current dyeing cycle of outlet device is also 8:30:10,
If default dyeing cycle is 1 second, 8:30:When 11, access device and outlet device enter next dyeing cycle.
It is one embodiment flow chart of inventive network quality determining method referring to Fig. 2, the embodiment is from access device
Network quality detection process is described for side.
Step 201, colored packet is sent in the first dyeing cycle.
Access device is responsible for dyeing service message, for example, the 0th ratio by the Flag fields in service message IP headings
Special position (reserved bit, is generally defaulted as 0) putting 1, obtains colored packet.
In the present invention length of dyeing cycle be typically at least more than twice access device to outlet device maximum transmitted when
Prolong.Access device completes the transmission of colored packet in this cycle within the preceding half cycle of the first dyeing cycle, to use
Jaws equipment can receive all colored packet that access device is sent within this cycle in same dyeing cycle, in the first dye
The quantity of the colored packet received in the color cycle is counted.
Step 202, binary number corresponding to the quantity of the colored packet of transmission in first dyeing cycle is determined.
The quantity of the colored packet sent in the first dyeing cycle is converted to corresponding binary number, example by access device
Such as, access device have sent 1000 colored packet in the first dyeing cycle, then corresponds to binary number as 1111101000.
Step 203, with continuous second dyeing cycle of first dyeing cycle in, determine to be sent multiple continuous
Service message and predetermined number boundary service message.
Wherein, multiple continuous service messages sort according to the sequence number of service message, and each service message corresponds to respectively
Bit in binary number, for example, binary number 1111101000 includes 10 binary digits, then need 10 companies
Continuous service message represents the binary number, and each service message corresponds to bit.Meanwhile determine predetermined number
Demarcate service message, the boundary service message is outside aforesaid plurality of continuous service message and with minimum the two of binary number
The continuous service message of the sequence number of service message corresponding to system position.
Step 204, service message corresponding to binary digit that value is 1 is dyed and sent, and sending value be 0 two
Service message corresponding to system position, and sequence number and the minimum binary digit pair in service message of demarcating to the predetermined number
The first boundary service message that the sequence number difference for the service message answered is maximum is dyed and sent.
Still by taking binary number 1111101000 as an example, it is assumed that the message for 10 continuous service messages that step 203 determines
Serial number 301~310, the highest binary digit that service message is corresponding in turn to binary number according to the order of sequence number from small to large arrive
Minimum binary digit, referring to Fig. 3, for the corresponding relation of binary number and multiple continuous service messages.
Exemplified by sending sequence number as 301 service message, the service message corresponds to the highest binary digit of binary number, should
The value of highest binary digit is 1, is sent after being dyed to the service message of the serial number 301, serial number 302,303,304,
305th, the value of binary digit is 1 corresponding to 307 service message, is sent after same dyeing；Serial number 306,308,309,310
Service message corresponding to the value of binary digit be 0, do not dye and directly transmit.In addition, this step is also to predetermined number point
The first maximum boundary service message of the sequence number difference of sequence number service message corresponding with minimum binary digit in boundary's service message
Dyed and sent.Referring to Fig. 4, for showing after service message dyeing of demarcating to multiple continuous service messages and predetermined number
It is intended to, the quantity of predetermined number boundary service message only has one in the figure, and therefore, the boundary service message is exactly first point
Boundary's service message, sent after being dyed to the first boundary service message.
Outlet device counts the quantity of the colored packet received in dyeing cycle, according to the colored packet received
Quantity determines that what current dyeing cycle received is the colored packet for detecting packet loss, is also intended to indicate that a dyeing week
The colored packet for the colored packet quantity that phase access device is sent.Access device is in the second dye it can be seen from description above
The colored packet that the color cycle sends is considerably less than the colored packet sent in the first dyeing cycle, therefore, can be on outlet device
A default dyeing counting position threshold value is (for example, can correspond to the maximum colored packet quantity for allowing to send in single dyeing cycle
Binary digit number as dyeing counting position threshold value), when the quantity of the colored packet received in dyeing cycle be less than it is pre-
If dyeing counting position threshold value when, illustrate that what current dyeing cycle received is intended to indicate that a dyeing cycle access device is sent out
The colored packet for the colored packet quantity sent, i.e. outlet device are currently at second dyeing cycle synchronous with access device.
Outlet device sorts to the service message received in the second dyeing cycle according to test serial number, it is determined that receive
First colored packet and last colored packet, as shown in figure 4, the service message of serial number 301 is first colored packet, sequence
Number it is last colored packet for 311 service message.Outlet device is according to positioned at first colored packet and last dye
Service message (including first colored packet and last colored packet) between color message determines access device in the first dye
The quantity for the colored packet that the color cycle sends.Specifically, outlet device enters according to access device identical service message with two
The corresponding relation of position processed, to reduce binary system corresponding to the quantity for the colored packet that access device is sent in the first dyeing cycle
Number, for example, as it was previously stated, service message is corresponding in turn to binary number most by access device according to the order of sequence number from small to large
High binary digit is to minimum binary digit, and therefore, the first colored packet that outlet device understands to receive corresponds to binary number
Highest binary digit, last colored packet is the first boundary service message, then according to predetermined number boundary business report
The quantity of text, it is determined that the message with the first boundary service message between first colored packet and last colored packet
The service message of sequence number difference predetermined number sequence number corresponds to the minimum binary digit of binary number, and then enters according to the two of reduction
The quantity of number processed and the colored packet received in the first dyeing cycle determines packet loss.
Further, in order to the service message for being used to represent quantity for preventing from sending in the second dyeing cycle occur packet loss or
Situations such as being tampered, access device of the present invention are utilized in predetermined number boundary service message in addition to the first boundary service message
Specified boundary service message as verification service message, utilize verify service message represent binary number check value.Specifically
For access device determines the check value of binary number, when check value is 1, to verification service message dyeing；When check value is 0
When, forbid to verification service message dyeing.For example, by taking odd as an example, the odd parity value of binary number (1111101000) is
1, therefore, to verification service message dyeing.Referring to Fig. 5, to include the dyeing schematic diagram of verification service message.Outlet device is based on
Specify boundary service message (verifying service message) to verify the binary number of reduction, pass through school in confirmation binary number
After testing, packet loss is determined according to the quantity of the binary number of reduction and the colored packet received in the first dyeing cycle；If
It is not validated, then abandon this wheel detection.
In addition, the present invention determines multiple continuous service messages and predetermined number point to be sent in execution step 203
During boundary's service message, it can will start multiple continuous service messages to be sent and pre- in the start time point of the second dyeing cycle
If quantity boundary service message is defined as multiple continuous service message and predetermined number boundary service messages to be sent.
So no matter access device first sends boundary service message, still first sends business report corresponding with the highest order of binary number
Text, what it is in the transmission of the second dyeing cycle start time point is all colored packet, and therefore, outlet device can be according in the second dyeing week
The time point of the first colored packet received in phase and the start time point of the second dyeing cycle determine time delay.
It can be seen from the above description that in whole detection process, all colored packet are based on the dyeing of regular traffic message,
And it is not related to the message interaction unrelated with business, the inspection to network quality is realized in the case of vacant additional network resources
Survey.
Now still by taking system shown in Figure 1 as an example, network quality detection process is discussed in detail.
Service message is sent to PC2 from PC1, R1 is access device, and R2 is outlet device, and detection service message is from R1 to R2
Packet loss and time delay.
ACL1 is configured on R1, the service message for being sent to PC2 to PC1 for indicating R1 dyes；Configured on R2
ACL2, the service message for being sent to PC2 to PC1 for indicating R2 carry out quality testing.Default dyeing cycle is 1s, at whole moment second
Start dyeing cycle, R1 and R2 clocks are synchronous, and therefore, dyeing cycle is also synchronous.Point subsequently to be used is preset on R1 and R2
The quantity of boundary's service message is 2, and specifies and continuously demarcate service message with the first boundary service message sequence number for verification industry
Business message.
R1 is 8:30:10 (dyeing cycle that the time point starts is designated as into T1) start the business report to matching ACL1 strategies
Literary (PC1 is sent to PC2 service message) is dyed (to the 0th bit position 1 of the Flag fields in IP headings) and sent,
After dyeing and sending 1000 service messages (1000 service messages are completed to send within the preceding half cycle), stop
Dyeing.
R2 connects in dyeing cycle T1 to service message (PC1 is sent to PC2 service message) statistics of matching ACL2 strategies
The quantity of the colored packet received, it is assumed that the quantity of the colored packet received in T1 is 990.
Compared with R2 is by the quantity 990 and default dyeing counting position threshold value (it is assumed that dyeing counting position threshold value is 22), in T1
The quantity of the colored packet of statistics is far longer than dyeing counting position threshold value, accordingly, it is determined that current dyeing cycle T1 receive be
The colored packet for being used to detect packet loss that R1 is sent.
The quantity 1000 for the colored packet that R1 sends the T1 cycles is converted to corresponding binary number 1111101000, and this two
System number includes 10 binary digits, to being represented in requisition for 10 continuous service messages, in addition it is also necessary to determine 2 boundary
Service message.R1 is to next dyeing cycle (8:30:11 start dyeing cycles, be designated as T2) start time point start it is to be sent
10 service messages sort (test serial number 301~310) according to test serial number, establish binary digit pass corresponding with service message
System, as shown in Figure 3.In the start time point 8 in T2 cycles:30:The business report of serial number 301 corresponding to 11 pairs of highest binary digits
Text is dyed and sent, and then, value is dyed and sent for service message corresponding to 1 binary digit successively according to numeric order,
Value is not dyed for service message corresponding to 0 binary digit and directly transmitted；Complete to sequence number corresponding to minimum binary digit
After transmission for 310 service message, start to send 2 boundary service message (service messages and serial number of serial number 311
312 service message), wherein, the service message of serial number 312 is the first boundary service message, the service message of serial number 311
To verify service message, because the odd parity value of binary number is 1, therefore, R1 after verification service message dyeing to sending；Again will
Sent after first boundary service message dyeing, referring to Fig. 5.
R2 counts the quantity that the PC1 received is sent to PC2 colored packet, as shown in Figure 5, T2 weeks in dyeing cycle T2
Colored packet quantity is 8 in phase, and the quantity (8) is less than default dyeing counting position threshold value (22), accordingly, it is determined that in the T2 cycles
The colored packet received is intended to indicate that the colored packet for the colored packet quantity that R1 is sent within the T1 cycles.
R2 sorts to the service message received in the T2 cycles by test serial number, it is determined that positioned at first colored packet and finally
Service message between one colored packet is the service message for representing colored packet quantity, wherein, first colored packet
Test serial number be 301, the test serial number of last colored packet is 312.Because R2 and R1 follow identical service message
With the corresponding relation of binary digit, therefore, R2 can determine that the service message of serial number 301 corresponds to the highest binary system of binary number
Position, the service message of serial number 312 are the first boundary service message, further according to the quantity (2) of default boundary service message,
It can determine that the service message of serial number 310 corresponds to the minimum binary digit of binary number, the sequence number with the first boundary service message
The service message of continuous serial number 311 is verification service message.Then, the value of binary digit corresponding to colored packet is set
For 1, the value of binary digit is arranged to 0 corresponding to non-staining message, completes the reduction of binary number, to the binary number after reduction
Carrying out odd, (the verification service message of serial number 311 is colored packet, and corresponding check value is 1), if binary number passes through school
Test, then confirm when the binary number of pre reduction is correct.Using after reduction binary number (1111101000, corresponding decimal number
1000) subtract the quantity 990 for the colored packet that the T1 cycles receive, then divided by quantity 1000, obtain packet loss as 1%.
At the same time, R2 can be according to the time for the first colored packet that R1 transmissions are received in the T2 cycles (it is assumed that being 8:
30:15ms after 11) with the initial time (8 in T2 cycles:30:11, R1 send first colored packet at the time point), when determining
Prolong as 15ms.
