All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

In addition, the term "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In this context, unless otherwise specified, the term "/" generally indicates that the associated object is an "or" relationship.

Embodiments of the present application are described in further detail below with reference to the drawings attached hereto.

The embodiment of the application provides a method for traffic congestion prevention configuration, which is executed by electronic equipment, wherein the electronic equipment can be a server or terminal equipment, and the server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server for providing cloud computing service. The terminal device may be, but is not limited to, a smart phone, a tablet computer, a notebook computer, a desktop computer, etc., and the terminal device and the server may be directly or indirectly connected through wired or wireless communication, which is not limited herein, and as shown in fig. 1, the method includes: step S101, step S102, step S103, and step S104, wherein,

step S101, the number of the plurality of ports of the device under test is acquired.

For the embodiment of the application, the number of a plurality of ports of the tested device is obtained, so that the number of rounds of sending the flow packets can be determined according to the number. Assume that the number of ports of the device under test is currently 4.

Step S102, the number of the rounds of sending the flow packets is determined based on the number of the plurality of ports.

For the embodiment of the present application, taking step S101 as an example, the number of the multiple ports of the current tested device is 4, and it is determined that the number of the rounds of sending the traffic packet is 3. The number of the rounds of sending the flow packets is specifically determined, and the number of the multiple ports of the tested device can be subtracted by one, namely the number of the rounds of sending the flow packets.

Step S103, when each port is determined to be a transmitting port, a corresponding receiving port in each transmitting round is determined, and a port configuration scheme corresponding to each port is obtained.

For the embodiment of the application, each port is determined to be the receiving port corresponding to each sending round as the sending end, so that the port configuration scheme corresponding to each port is obtained, and the subsequent determination of the flow packet sending scheme of the tested device according to the port configuration scheme is facilitated. Taking step S101 and step S102 as an example, assume that the current 4 ports are port a, port b, port c, and port d, respectively. Assuming that the port a corresponds to the receiving port b in the 1 st transmission round, the receiving port c in the 2 nd transmission round, and the receiving port d in the 3 rd transmission text, the port configuration schemes corresponding to the port a may be a-b, a-c, and a-d.

Step S104, determining a flow packet transmission scheme of the tested device based on the port configuration scheme corresponding to each port.

Each port in each round of transmission scheme of the traffic packet transmission scheme is only used as a primary transmission port, and is only used as a primary receiving port.

For the embodiment of the application, the flow packet sending scheme of the tested device is determined according to the port configuration scheme corresponding to each port, and because each port is only used as a sending port and only used as a receiving port once in each round of sending scheme of the flow packet sending scheme, when the tested device is tested according to the flow packet sending scheme, the condition that one port is used as the receiving ports of a plurality of sending ends is effectively reduced, and the probability of flow congestion of the tested device in the testing process is further reduced.

Taking step S103 as an example, the port configuration schemes corresponding to the port a are a-b, a-c and a-d. Let port b correspond to port configuration schemes b-c, b-d, and b-a. The port configuration schemes corresponding to the port c are c-d, c-a and c-b. The port configuration schemes corresponding to the port d are d-a, d-b and d-c. The determined traffic packet transmission scheme of the tested device is port a: a-b, a-c, a-d, port b: b-c, b-d, b-a, port c: c-d, c-a, and c-b, and port d: d-a, d-b and d-c. It is apparent that in the first round transmission scheme (a-b, b-c, c-d, and d-a), each port acts as a primary transmit port and a primary receive port only. Therefore, in each round of transmission scheme, one port is not used as a receiving port corresponding to a plurality of transmitting ports, and the effect of preventing traffic congestion is achieved.

In this embodiment of the present application, for convenience in describing description according to one data stream, that is, when transmitting according to a transmission scheme, only one data stream is used for detection, because each data stream may correspond to different detection contents, for example, an S1 data stream may be used as a case when detecting that a device under test runs ipv4, an S2 data stream may be used as a case when detecting that a device under test runs ipv6, so that multiple data streams may be set according to a user requirement for detection, for example, the S1 data stream may be first put into the transmission scheme to detect the case that the device under test runs ipv4, and when the electronic device detects that the operation of the S1 data stream according to the transmission scheme is completed, the S2 data stream may be automatically put into the transmission scheme so as to continuously detect the running condition of ipv 6.

In this embodiment of the present application, when detecting that a user needs to detect multiple streams, a corresponding number of transmission schemes may be generated according to the number of data streams, that is, the detection schemes when each data stream runs may be different, for example, two streams of an S1 data stream and an S2 data stream are currently calculated correspondingly, and the S1 data stream is placed in the first transmission scheme and the S2 data stream is placed in the second transmission scheme.

In one possible implementation manner of the embodiment of the present application, when determining each port as a transmitting port, step S103 includes step S1031 (not shown in the figure), step S1032 (not shown in the figure), step S1033 (not shown in the figure), step S1034 (not shown in the figure), and step S1035 (not shown in the figure) in each transmitting round corresponding to the receiving port, and obtaining a port configuration scheme corresponding to each port,

step S1031, obtaining the arrangement sequence of the plurality of ports and the serial number of each port.

The serial number of each port is the serial number of each port minus one in the position serial number in the arrangement sequence.

For the embodiment of the application, the arrangement sequence of the plurality of ports and the serial number of each port are obtained, wherein the serial number of each port is the serial number of the position of each port in the arrangement sequence minus one, that is, the serial number of each port is one less than the position serial number of each port in the arrangement sequence. Assuming that the plurality of ports are port a, port b, port c and port d, and the order is port a, port b, port c and port d, the serial number of port a is 0, the serial number of port b is 1, the serial number of port c is 2 and the serial number of port d is 3.

Step S1032, determining the current transmitting port according to the arrangement sequence.

The first serial number is the serial number of the current sending port, and the second serial number is the serial number of the second port in the arrangement sequence.

For the embodiment of the present application, taking step S1031 as an example, the first sequence number is the sequence number of the current transmitting port, and assuming that the first sequence number is 0 and the second sequence number is the sequence number of the second port in the permutation sequence, the second sequence number is 1. Summing the first serial number and the second serial number to obtain a sum of 1, performing remainder operation on the 1 and the number of ports 4 to obtain a value of 1, determining the port corresponding to the 1 as a receiving port, namely determining the port b as the receiving port, and adding 1 to the second serial number to obtain a third serial number, namely, the third serial number is 2.

Step S1034, the first loop step is performed until the third sequence number is the largest sequence number among the sequence numbers of each port.

Wherein the first cycling step comprises:

determining the sum of a first serial number and a third serial number, wherein the first serial number is the serial number of the current transmitting port, performing remainder taking operation on the sum and the number of ports to obtain a remainder taking value, determining the port corresponding to the remainder taking value as a receiving port, adding the current third serial number to obtain a third serial number in the next receiving port determining period, and judging whether the current third serial number is the largest serial number in the serial numbers of each port.

For the embodiment of the present application, taking step S1031 as an example, the current transmitting end is taken as a port a, according to step S1033, it is determined that the receiving port of the port a in the first transmitting round is a port b, the first serial number is the serial number of the current transmitting port, that is, the first serial number is 0, the third serial number is 2, the sum of 0 and 2 is obtained, 2 and the number 4 are subjected to remainder taking operation, and the remainder is 2, because the port corresponding to 2 is a port C, the port C is determined as the receiving port of the port a in the second transmitting round, the step is circularly performed, it is determined that the receiving port corresponding to the port a in the first transmitting round is a port b, the receiving port corresponding to the second transmitting round is a port C, and the receiving port corresponding to the third transmitting round is a port d, thereby achieving the effect of determining the receiving port corresponding to each transmitting round of the current transmitting port. When the third serial number is 3, it indicates that the port configuration scheme of the port a has been found, that is, the execution of the first loop step is stopped.

Step S1035, the second circulation step is circularly executed until the current sending port is the last port in the arrangement order, so as to obtain the port configuration scheme corresponding to each port.

Wherein the second cycling step comprises:

determining a current transmitting port according to the arrangement sequence;

determining the sum of the first serial number and the second serial number, performing remainder taking operation on the sum and the number of ports to obtain a remainder taking value, determining the port corresponding to the remainder taking value as a receiving port, adding one to the second serial number to obtain a third serial number, wherein the first serial number is the serial number of the current transmitting port, and the second serial number is the serial number of the second port in the arrangement sequence;

For the embodiment of the present application, the second loop step is performed in a loop until the current transmitting port is the last port in the permutation sequence, that is, when the first serial number is 3, it is indicated that the port configuration scheme of the port d is being calculated at this time, and since the port d is the last port in the permutation sequence, the second loop step is stopped. And the second circulation step comprises determining the current transmitting port according to the arrangement sequence, wherein the first serial number is the serial number of the current transmitting port, the second serial number is the serial number of the second port in the arrangement sequence, summing the first serial number and the second serial number, performing residual operation on the obtained sum and the number of the ports, obtaining residual values, determining the ports corresponding to the residual values as receiving ports, adding 1 to the second serial number, obtaining a third serial number, and performing the first circulation step in a circulation mode until the third serial number is the largest serial number in the serial numbers of the ports, thereby achieving the effect of determining the port configuration scheme corresponding to the ports.

For the embodiment of the present application, when each port is used as a transmitting end, the second loop step is corresponding to one time, and the first loop step is executed three times when the second loop step is executed once.

In the embodiment of the present application, the number of the plurality of ports may be an even number, and the plurality of ports may be divided into two parts on average, where one part is used as a transmitting port and the other part is used as a receiving port. For example, when calculating the configuration scheme corresponding to each port, the current multiple ports are port a, port b, port c, port d, port e and port f, the arrangement sequence of the multiple ports and the serial number of each port may be obtained, where the serial number of each port is the serial number of each port minus one in the position serial number in the arrangement sequence, and the current transmitting port is determined according to the arrangement sequence; determining the sum of the first serial number and the second serial number, performing residual taking operation on the sum and the number of ports to obtain a residual taking value, judging whether the port corresponding to the residual taking value belongs to a receiving port, if so, determining the port as the receiving port corresponding to the sending port, and adding one to the second serial number to obtain a third serial number, wherein the first serial number is the serial number of the current sending port, and the second serial number is the serial number of the second port in the arrangement sequence; and executing the first circulation step until the third serial number is the largest serial number in the serial numbers of the ports.

One possible implementation manner of the embodiment of the present application further includes step S105 (not shown in the figure), step S106 (not shown in the figure), and step S107 (not shown in the figure), where,

step S105, determining a sum of the first value and the second value.

The first value is the value of any sending round, and the second value is the serial number of each port.

For the embodiment of the present application, the first value is the value of any transmission round, and if the current transmission round is 1, the first value is 1, the second value is the serial number of each port, and if the serial number of port a is 0, the serial number of port b is 1, the serial number of port c is 2, and the serial number of port d is 3. Assuming that the receiving port of the port a at the first transmission round is currently to be determined, the second value is 0. The sum of the first value and the second value is determined to be 1.

Step S106, calculating the sum and the remainder of the number of the plurality of ports.

For the embodiment of the present application, 1 is divided by the number of multiple ports 4, resulting in a remainder value of 1.

Step S107, determining the port corresponding to the residual value as the receiving port when each port is used as the transmitting end in any transmitting round.

For the embodiment of the present application, if the port corresponding to 1 is the port b, it is determined that in the first transmission round, when the port a is used as the transmission port, the receiving port is the port b, so as to achieve the purpose of determining that each port is used as the corresponding receiving port when the port is used as the transmission port in each transmission round.

In this embodiment of the present application, when determining that each port is used as a transmitting port in each transmitting round, a manner of a corresponding receiving port may also be: and determining the port corresponding to any sequence number as a transmitting port, determining the ports corresponding to other sequence numbers except any sequence number in the arrangement sequence as receiving ports, respectively differencing the sequence numbers corresponding to the receiving ports with any sequence number, determining the difference value as the turn of the receiving port corresponding to the sequence number if the difference value is positive, summing the difference value and the number of the plurality of ports if the difference value is negative, and determining the sum value as the turn of the receiving port corresponding to the sequence number. For example, the port corresponding to the sequence number 0 is the port a, the port a is used as a transmitting port, the port b, the port c and the port d are determined as receiving ports of the port a, for example, the port c corresponds to the sequence number 2, the port c is determined as receiving port of the port a, when a specific transmitting round is performed, the sequence number of the port c and the sequence number of the port a may be differed, and when the difference is 2, the port c is the receiving port corresponding to the port a when the second transmitting round is performed.

Assuming that when the port b is a transmitting end, the corresponding sequence number of the port b is 1, that is, any sequence number is 1, when determining that the port a is a receiving port of the port b, in a specific transmitting round, the sequence number 0 of the port a and the sequence number 1 of the port b are differenced to obtain a difference value of-1, and because the difference value is a negative value, the sum of-1 and the port number 4 can be continuously summed to obtain a sum value of 3, and when the port a is the receiving port of the port b, the port a is in a third transmitting round.

One possible implementation of an embodiment of the present application, step S108 (not shown in the figure) and step S109 (not shown in the figure), where,

step S108, judging whether ports with a preset port configuration scheme exist in the ports or not.

For the embodiment of the application, the preset port configuration scheme is a preset configuration scheme, and whether ports with the preset port configuration scheme exist in the plurality of ports is judged, so that whether the arrangement sequence of specific basis when the port configuration scheme of each port is required to be determined according to the preset port configuration scheme is determined or not is determined.

Suppose that the user has set the port configuration schemes a-b, a-c, and a-d for port a among port a, port b, port c, and port d.

Step S109, if yes, determining the arrangement sequence of the plurality of ports based on a preset port configuration scheme.

For the embodiment of the present application, taking step S108 as an example, port a is a port having a preset configuration scheme, so that the arrangement sequence of the plurality of ports can be determined according to a-b, a-c, and a-d, and the determined arrangement sequence can be port a, port b, port c, and port d. According to the arrangement sequence, the port configuration scheme of each port in the plurality of ports is determined, so that the port a can meet the requirement of a user, and the flow configuration schemes of the port b, the port c and the port d can be determined.

One possible implementation manner of the embodiment of the present application further includes step S110 (not shown in the figure), step S111 (not shown in the figure), and step S112 (not shown in the figure), where,

step S110, if there are at least two ports with preset port configuration schemes, outputting at least two preset port configuration schemes.

For the embodiment of the application, when at least two ports with preset port configuration schemes exist, at least two arrangement sequences are determined according to the at least two preset port configuration schemes, so that when the traffic packet transmission scheme is determined according to the arrangement sequences, the traffic packet transmission scheme cannot be determined according to which arrangement sequence.

Assuming that the preset port configuration schemes corresponding to the current port a are a-B, a-c and a-d, the determined arrangement sequence according to the preset port configuration scheme of the port a may be a, B, c and d, the preset port configuration schemes corresponding to the current port B are B-a, B-c and B-d, and the determined arrangement sequence according to the preset port configuration scheme of the port B may be B, a, c and d. Obviously, two arrangement sequences are determined according to two preset port configuration schemes. Thus, when there are ports of at least two preset port configuration schemes, the at least two preset port configuration schemes may be output so that the user selects a preset port configuration scheme that can be used.

In this embodiment of the present application, at least two preset port configuration schemes may be output on a terminal device of a user, or at least two preset port configuration schemes may be output on a display screen, or at least two preset port configuration schemes may be output in a voice broadcast manner, which is not limited herein.

Step S111, determining a target preset port configuration scheme according to a confirmation instruction triggered by a user.

For the embodiment of the present application, an example is given, where the target preset port configuration scheme is a preset port configuration scheme corresponding to the port a. The user confirms the target preset port configuration scheme, so that the preset port configuration scheme which is specifically used for generating the arrangement sequence is conveniently and definitely the preset port configuration scheme corresponding to the port a.

When the user triggers the confirmation instruction, the confirmation instruction can be triggered by input devices such as a keyboard, a mouse, a touch screen and the like, or can be triggered by sending a voice instruction to the user, and the confirmation instruction is not limited herein.

Step S112, determining the arrangement sequence of the plurality of ports based on the target preset port configuration scheme.

For the embodiment of the present application, in the above example, the target preset port configuration scheme is a preset port configuration scheme corresponding to the port a, and the determined arrangement sequence of the plurality of ports may be a, b, c, and d.

One possible implementation manner of the embodiment of the present application further includes step S113 (not shown in the figure), step S114 (not shown in the figure), and step S115 (not shown in the figure), where,

step S113, a specified number of traffic packets are sent to each port.

For the embodiment of the application, a specified number of traffic packets are sent to each port, so that the tested device can be detected according to the traffic packets. Assuming that the number of traffic packets corresponding to port a is 20, the number of traffic packets corresponding to port b is 30, the number of traffic packets corresponding to port c is 20, and the number of traffic packets corresponding to port d is 40.

Step S114, the number of traffic packets at the corresponding receiving port in each transmission round is obtained for each port.

For the embodiment of the present application, it is assumed that the corresponding receiving port of the port a in the first transmission round is the port b, and since in the embodiment of the present application, the traffic packets corresponding to the port a, the port b, the port c and the port d are simultaneously transmitted to the corresponding receiving ports, the number of the traffic packets at the port b in the first transmission round is 20.

Step S115, determining a detection result of the device under test based on the number of traffic packets and the specified number.

For the embodiment of the present application, taking step S113 and step S114 as examples, if the number of the traffic packets of the port b is detected to be 20 in the first transmission round, it is indicated that there is no problem in the process of a-b, comparing the traffic at all receiving ends with the designated number of the ports of the transmitting end corresponding to the receiving end, so as to determine whether there is an abnormality in the transmission process of each two ports, and when there is no abnormality in the transmission process of each two ports, i.e. the number of the traffic packets is consistent with the designated number, it is indicated that there is no abnormality in the tested device, i.e. the detection result may be no abnormality; when there is an abnormality in the two port transmission process, that is, when the number of the traffic packets is inconsistent with the specified number, it is indicated that the tested device is abnormal, that is, the detection result may be abnormal.

In the embodiment of the application, the detection result can be output on the terminal equipment corresponding to the user, such as a mobile phone, so that the user can watch the detection result in time, and the detection result can also be output in a voice broadcasting mode.

In the embodiment of the application, when the electronic device detects the device to be detected according to the transmission scheme, the detection time of the device to be detected can be determined according to the user, i.e. the user can set the time when the device to be detected is in the detection state.

Further, in the embodiment of the present application, the arrangement sequence of the plurality of ports may be rearranged to obtain a reordered secondary arrangement sequence, a secondary traffic packet transmission scheme may be obtained according to the secondary arrangement sequence, and the tested device may be detected according to the secondary traffic packet transmission scheme to obtain a secondary detection result, and the first detection result may be verified according to the secondary detection result, so as to increase accuracy of the detection result. In the embodiment of the application, the arrangement sequence can be further disturbed for a plurality of times, so that a plurality of detection results are obtained, and the accuracy of the detection results is higher. In the embodiment of the present application, the shuffle function may be used as the function for scrambling the arrangement order.

One possible implementation manner of the embodiment of the present application further includes step S116 (not shown in the figure), step S117 (not shown in the figure), step S118 (not shown in the figure), and step S119 (not shown in the figure), where step S116 may be performed before step S101, may be performed after step S101, may be performed simultaneously with step S101, where,

step S116, the packet length of the flow packet corresponding to each port is obtained.

For the embodiment of the application, the packet length of the flow packet corresponding to each port is obtained so as to judge whether the packet fields of each flow packet are the same, thereby being convenient for judging whether the flow packet can reach the receiving port at the same time when each port transmits the flow packet according to the same transmission rate.

Assuming that the packet length of the traffic packet corresponding to the port a is 3000 bytes, the packet length of the traffic packet corresponding to the port b is 4000 bytes.

Step S117, judging whether the packet length of the flow packet corresponding to each port is the same.

For the embodiment of the present application, taking step S116 as an example, it is determined whether the packet lengths of the traffic packets corresponding to the port a and the port b are the same, so as to determine whether the transmission rates of the port a and the port b need to be set.

In step S118, if the packet lengths of the traffic packets are different, the rate ratios of the ports are determined based on the packet lengths of the traffic packets.

Wherein the rate ratio is the speed ratio of the traffic packets transmitted by the plurality of ports.

For the embodiment of the present application, the packet lengths of the corresponding traffic packets of the port a and the port b are different, which means that if the port a and the port b send the traffic packets according to the same sending rate, the traffic packets cannot reach the receiving ports corresponding to the port a and the port b at the same time, so that the next sending round is affected. It is thus possible to compare the packet lengths to obtain a packet length ratio of 3 for port a to port b: and 4, determining that the rate ratio of the port a to the port b is 3:4.

Step S119, setting transmission rates of the plurality of ports based on the rate ratio.

For the embodiment of the application, the rate ratio is the speed ratio of transmitting the traffic packets by the plurality of ports, and the transmission rates of the plurality of ports are set according to the rate ratio, so that the traffic packets of each sending end can reach the receiving port at the same time, and the situation of traffic congestion can be effectively reduced when the tested equipment is detected according to the traffic packet sending scheme. In the above example, the ratio of the transmission rates of the port a and the port b is set to 3:4, the traffic packets sent by the port a and the port b can reach the corresponding receiving ports at the same time.
