Referring to fig. 1, a schematic diagram of a network quality detection system according to an embodiment of the present invention is shown. The system comprises two terminal devices PC1 and PC2, two routing devices R1 and R2. If the traffic message is sent from the PC1 to the PC2, R1 is the ingress device, and R2 is the egress device, and the network quality from the ingress device to the egress device is detected.
Before detection, an ingress device and an egress device are configured, and it is specified which service flow is based on which network quality detection is performed, for example, five-tuple information (source IP address, source port number, destination IP address, destination port number, protocol type) of the service flow is added to an Access Control List (ACL) of the ingress device and the egress device, network quality detection is performed based on a service packet matching the ACL, and meanwhile, the ingress device is specified to dye the service packet, where dyeing refers to identifying a certain feature bit of the service packet to distinguish from other service packets.
In addition, the clocks of the inlet device and the outlet device are synchronized, and the dyeing cycle is synchronized, for example, if the starting time of the current dyeing cycle of the inlet device is 8:30:10, the starting time of the current dyeing cycle of the outlet device is also 8:30:10, and if the preset dyeing cycle is 1 second, the inlet device and the outlet device both enter the next dyeing cycle at 8:30: 11.
Referring to fig. 2, a flowchart of an embodiment of the network quality detection method according to the present invention is shown, where the embodiment describes a network quality detection process from an ingress device side.
Step 201, sending a dyeing message in a first dyeing period.
The ingress device is responsible for dyeing the service packet, for example, setting bit 0 (reserved bit, usually default to 0) of a Flag field in an IP packet header of the service packet to 1, so as to obtain a dyed packet.
The length of the dyeing cycle in the present invention is generally at least greater than twice the maximum transit time delay from the inlet device to the outlet device. The inlet device finishes the sending of the dyeing messages in the first half period of the first dyeing period, so that the outlet device can receive all the dyeing messages sent by the inlet device in the first dyeing period, and the number of the dyeing messages received in the first dyeing period is counted.
Step 202, determining binary numbers corresponding to the number of the dyeing messages sent in the first dyeing period.
The ingress device converts the number of the dyeing messages sent in the first dyeing cycle into a corresponding binary number, for example, if the ingress device sends 1000 dyeing messages in the first dyeing cycle, the corresponding binary number is 1111101000.
Step 203, in a second dyeing cycle continuous with the first dyeing cycle, determining a plurality of continuous service messages to be sent and a preset number of boundary service messages.
A plurality of continuous service messages are sorted according to the sequence number of the service message, and each service message corresponds to a binary bit in the binary number, for example, the binary number 1111101000 includes 10 binary bits, and then 10 continuous service messages are required to represent the binary number, and each service message corresponds to a binary bit. And simultaneously, determining a preset number of boundary service messages, wherein the boundary service messages are service messages which are except the plurality of continuous service messages and have continuous serial numbers of the service messages corresponding to the lowest binary digits of the binary numbers.
And 204, dyeing and transmitting the service message corresponding to the binary digit with the value of 1, transmitting the service message corresponding to the binary digit with the value of 0, and dyeing and transmitting the first demarcation service message with the largest difference between the serial number in the preset number of demarcation service messages and the serial number of the service message corresponding to the lowest binary digit.
Still taking the binary number 1111101000 as an example, assuming that the message sequence numbers of 10 consecutive service messages determined in step 203 are 301-310, the service messages sequentially correspond to the highest binary bit to the lowest binary bit of the binary number according to the sequence number from small to large, see fig. 3, which is the corresponding relationship between the binary number and a plurality of consecutive service messages.
Taking the service message with the transmission serial number of 301 as an example, the service message corresponds to the highest binary digit of the binary number, the value of the highest binary digit is 1, the service message with the serial number of 301 is transmitted after being dyed, the values of the binary digits corresponding to the service messages with the serial numbers of 302, 303, 304, 305 and 307 are all 1, and the service messages are transmitted after being dyed; the values of binary bits corresponding to the service messages with sequence numbers 306, 308, 309, and 310 are all 0, and the service messages are sent directly without dyeing. In addition, the step also dyes and transmits the first boundary service message with the largest difference between the serial number in the boundary service messages with the preset number and the serial number of the service message corresponding to the lowest binary digit. Referring to fig. 4, a schematic diagram of a plurality of continuous service messages and a preset number of boundary service messages after being dyed is shown, where the number of the preset number of boundary service messages in the schematic diagram is only one, and therefore, the boundary service message is a first boundary service message, and the first boundary service message is sent after being dyed.
The outlet equipment counts the number of the received dyeing messages in the dyeing period, and determines whether the dyeing messages used for detecting the packet loss rate or the dyeing messages used for representing the number of the dyeing messages sent by the inlet equipment in the previous dyeing period are received in the current dyeing period according to the number of the received dyeing messages. As can be seen from the foregoing description, the dyeing message sent by the ingress device in the second dyeing period is significantly less than the dyeing message sent in the first dyeing period, so that a dyeing count bit threshold may be preset on the egress device (for example, the number of binary bits corresponding to the maximum number of dyeing messages allowed to be sent in a single dyeing period may be used as the dyeing count bit threshold), and when the number of dyeing messages received in a dyeing period is less than the preset dyeing count bit threshold, it indicates that the dyeing message sent by the ingress device in the previous dyeing period is received in the current dyeing period, that is, the egress device is currently in the second dyeing period synchronized with the ingress device.
The egress device sorts the service messages received in the second dyeing cycle according to the message sequence numbers, and determines the first dyeing message and the last dyeing message received, as shown in fig. 4, the service message with the sequence number 301 is the first dyeing message, and the service message with the sequence number 311 is the last dyeing message. The exit device determines the number of the dyeing messages sent by the entry device in the first dyeing period according to the service messages (including the first dyeing message and the last dyeing message) between the first dyeing message and the last dyeing message. Specifically, the egress device restores the binary number corresponding to the number of the dyeing messages sent by the ingress device in the first dyeing cycle according to the same corresponding relationship between the service message and the binary number as the ingress device, for example, as mentioned above, the ingress device sequentially corresponds the service packets to the highest binary digit to the lowest binary digit of the binary digits according to the sequence number from small to large, therefore, the egress device can know that the first dyeing message received corresponds to the highest binary bit of the binary number, and the last dyeing message is the first demarcation service message, then according to the number of the preset number of boundary service messages, determining the lowest binary bit of the binary number corresponding to the service message which is positioned between the first dyeing message and the last dyeing message and has the difference of the message serial number of the first boundary service message by the preset number of serial numbers, and determining the packet loss rate according to the restored binary number and the number of the dyeing messages received in the first dyeing period.
Further, in order to prevent the service messages sent in the second dyeing cycle and used for representing the number from being lost or tampered, the inlet device of the present invention uses the designated boundary service messages except the first boundary service message in the preset number of boundary service messages as the check service messages, and uses the check service messages to represent the check value of the binary number. Specifically, the ingress device determines a check value of a binary number, and dyes the check service message when the check value is 1; and when the check value is 0, the check service message is prohibited from being dyed. For example, taking the odd parity as an example, the odd parity value of the binary number (1111101000) is 1, so the check service message is dyed. Referring to fig. 5, a schematic view of a dyeing process including a check service packet is shown. The outlet equipment checks the restored binary number based on the specified boundary service message (namely, the check service message), and determines the packet loss rate according to the restored binary number and the number of the dyeing messages received in the first dyeing period after the binary number is confirmed to pass the check; if the verification is not passed, the round of detection is abandoned.
In addition, when step 203 is executed to determine a plurality of continuous service messages to be sent and a preset number of demarcation service messages, the present invention may determine the plurality of continuous service messages to be sent and the preset number of demarcation service messages to be sent starting at the starting time point of the second dyeing cycle as the plurality of continuous service messages to be sent and the preset number of demarcation service messages. Therefore, no matter the inlet equipment sends the boundary service message first or sends the service message corresponding to the highest bit of the binary number first, the dyeing message is sent at the starting time point of the second dyeing period, and therefore, the outlet equipment can determine the time delay according to the time point of the first dyeing message received in the second dyeing period and the starting time point of the second dyeing period.
It can be seen from the above description that, in the whole detection process, all the dyed messages are dyed based on normal service messages, and no message interaction irrelevant to the service is involved, so that the detection of the network quality is realized under the condition of not occupying additional network resources.
The network quality detection process will now be described in detail by taking the system shown in fig. 1 as an example.
The service message is sent from the PC1 to the PC2, where R1 is an ingress device, and R2 is an egress device, and the packet loss rate and the time delay of the service message from R1 to R2 are detected.
Configuring ACL1 on R1, wherein the ACL1 is used for indicating R1 to dye a service message sent by a PC1 to the PC 2; and an ACL2 is configured on the R2 and used for indicating the R2 to carry out quality detection on the service message sent by the PC1 to the PC 2. The preset dyeing period is 1s, the dyeing period is started at the time of the whole second, and R1 and R2 are synchronized in clock, so that the dyeing period is also synchronized. The number of boundary service messages to be used subsequently is preset to be 2 on R1 and R2, and boundary service messages continuous with the sequence number of the first boundary service message are designated as check service messages.
R1 starts to dye the traffic packet (traffic packet sent by PC1 to PC 2) matching the ACL1 policy at 8:30:10 (the dyeing cycle started at this time point is denoted as T1) (bit position 0 of Flag field in IP packet header 1) and sends it, and stops dyeing after dyeing and sending 1000 traffic packets (the 1000 traffic packets are sent in the first half of the cycle).
R2 counts the number of received dye messages for the service messages (service messages sent from PC1 to PC 2) matching the ACL2 policy in the dye cycle T1, and assumes that the number of received dye messages in T1 is 990.
The R2 compares the number 990 with a preset dye count bit threshold (assuming that the dye count bit threshold is 22), and the number of dye messages counted in the T1 is far greater than the dye count bit threshold, so that it is determined that the dye message sent by the R1 and used for detecting the packet loss rate is received in the current dye cycle T1.
R1 converts the number 1000 of the dyeing messages sent in the T1 cycle into the corresponding binary number 1111101000, where the binary number includes 10-bit binary bits, and 10 continuous service messages are correspondingly required for representation, and in addition, 2 boundary service messages also need to be determined. R1 sorts the 10 service messages to be sent at the starting time point of the next dyeing cycle (8:30:11 starting dyeing cycle, denoted as T2) according to the message sequence numbers (message sequence numbers 301 to 310), and establishes the corresponding relationship between the binary bits and the service messages, as shown in fig. 3. Dyeing and sending the service message with the serial number of 301 corresponding to the highest binary digit at the starting time point 8:30:11 of the T2 period, then dyeing and sending the service message corresponding to the binary digit with the value of 1 in sequence according to the serial number sequence, and directly sending the service message corresponding to the binary digit with the value of 0 without dyeing; after the transmission of the service message with the sequence number of 310 corresponding to the lowest binary digit is completed, starting to transmit 2 boundary service messages (the service message with the sequence number of 311 and the service message with the sequence number of 312), wherein the service message with the sequence number of 312 is a first boundary service message, the service message with the sequence number of 311 is a check service message, and since the odd check value of the binary digit is 1, R1 dyes the check service message and transmits the check service message; and then the first demarcation service message is sent after being dyed, see fig. 5.
As can be seen from fig. 5, the number of the received dye messages sent by the PC1 to the PC2 in the dye cycle T2 is counted by R2, and the number of the received dye messages in the T2 cycle is 8, and the number (8) is smaller than the preset dye count bit threshold (22), so that it is determined that the dye messages received in the T2 cycle are dye messages used for indicating the number of the dye messages sent by R1 in the T1 cycle.
R2 sorts the service messages received in the T2 period according to the message serial numbers, and determines that the service message located between the first dyed message and the last dyed message is the service message used for representing the number of the dyed messages, wherein the message serial number of the first dyed message is 301, and the message serial number of the last dyed message is 312. Since R2 and R1 follow the same correspondence between service packets and binary digits, R2 may determine that the service packet with sequence number 301 corresponds to the highest binary digit of the binary digits, the service packet with sequence number 312 is the first demarcation service packet, and then, according to the number (2) of the preset demarcation service packets, may determine that the service packet with sequence number 310 corresponds to the lowest binary digit of the binary digits, and the service packet with sequence number 311 consecutive to the sequence number of the first demarcation service packet is the verification service packet. Then, setting the value of the binary digit corresponding to the dyeing message to 1, and setting the value of the binary digit corresponding to the non-dyeing message to 0, completing the restoration of the binary digit, performing odd check on the restored binary digit (the check service message with the serial number of 311 is the dyeing message, and the corresponding check value is 1), and if the binary digit passes the check, determining that the currently restored binary digit is correct. The number 990 of the dyeing messages received in the period T1 is subtracted from the restored binary number (1111101000, corresponding to the decimal number of 1000), and the obtained value is divided by the number of 1000, so that the packet loss rate is 1%.
Meanwhile, R2 may determine the delay to be 15ms according to the time (assumed to be 15ms after 8:30: 11) of receiving the first dye message sent by R1 in the T2 period and the start time (8:30:11, R1 sends the first dye message at this time point) of the T2 period.
