Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, interfaces, techniques, etc., in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
The invention provides a method and a system for detecting a communication state.
According to an aspect of the present invention, an embodiment of the present invention provides a method for detecting a communication status.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a method for detecting a communication status according to an embodiment of the present invention.
As shown in fig. 1, the method includes:
step S100: the first controller selects a target communication link according to a preset communication link selection rule;
step S200: sending a detection message to the second controller over the target communication link;
step S300: and determining the communication state between the first gateway cluster and the second gateway cluster according to the received feedback message which is sent by the second controller and corresponds to the detection message.
The first gateway cluster comprises N first gateways and a first controller, the second gateway cluster comprises M second gateways and a second controller, and at least one first gateway in the first gateway cluster and at least one second gateway in the second gateway cluster have a communication link. Wherein N and M are integers greater than 1.
In this embodiment, the first controller selects the target communication link according to a preset communication link selection rule. After the selection of the target communication link is completed, a detection message is sent to the second controller according to the target communication link.
For example: and the first controller selects a target communication link from the five communication links according to the communication link selection rule. It should be noted that the target communication link may be multiple or one.
The first controller sends the detection message to the second controller according to the selected target communication link.
After receiving the detection message sent by the first controller, the second controller sends a feedback message to the first controller according to the detection message.
In a technical solution that may be implemented, if the first controller does not receive the feedback message sent by the second controller within a preset time, it indicates that the communication state of the first gateway cluster and the second gateway cluster is a disconnected state.
In the prior art, the communication states of the first gateway cluster and the second gateway cluster are determined by judging the communication state of each communication link.
In the present application, the communication state of each communication link does not need to be acquired, but only the target communication link is selected according to the preset communication link selection rule, and the communication states of the first gateway cluster and the second gateway cluster are determined through the target communication link.
That is, with the technical solution provided in this embodiment, the technical disadvantages of traffic consumption and resource waste when acquiring the state of each communication link in the prior art are avoided. And the communication state is judged through the target communication link, so that a large amount of data processing processes are avoided, time and resources are saved, and the technical effects of efficiently and quickly acquiring the communication states of the first gateway cluster and the second gateway cluster are achieved.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for detecting a communication status according to another embodiment of the present invention.
As shown in fig. 2, step S100 specifically includes:
step S110: the first controller counts the number of communication links between each first gateway and all second gateways;
step S120: determining a set of communication links according to the number of communication links;
step S130: in the set of communication links, the first controller selects a target communication link according to a communication link selection rule.
In this embodiment, it is understood that there may be a communication link between each first gateway and each second gateway, and the number of communication links may be multiple, and the number of communication links between each first gateway and all second gateways is counted.
The set of communication links is determined based on the number of communication links (either high or low).
For example, there are communication links between the first gateway a and the second gateway B, and the number of the communication links is three. Meanwhile, a communication link also exists between the first gateway a and the second gateway C, and the number of the communication links is two.
The set of communication links may be determined from a large number of communication links, i.e. the communication links between the first gateway a and the second gateway B are added to the set of communication links.
Of course, the communication link set may also be determined according to a small number of communication links, that is, the communication links between the first gateway a and the second gateway C are added to the communication link set.
When the communication link set is determined according to the large number of communication links, one or two communication links are selected as target communication links among three communication links between the first gateway a and the second gateway B according to a communication link selection rule.
When the communication link set is determined according to a large number of communication links, one or two communication links are selected as a target communication link between two communication links between the first gateway a and the second gateway B according to a communication link selection rule.
According to the technical scheme provided by the embodiment, multiple or one communication link is selected as a target communication link in a communication link set according to a communication link selection rule, and the detection message is sent according to the target communication link. Compared with the prior art, the method and the device have the advantages that the communication state of each communication link is obtained to determine the communication states of the first gateway cluster and the second gateway cluster, so that the flow is saved, the time is saved, and the load of communication equipment for data processing is reduced. The technical effect of rapidly and efficiently acquiring the communication states of the first gateway cluster and the second gateway cluster is achieved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for detecting a communication status according to another embodiment of the present invention.
As shown in fig. 3, step S120 specifically includes:
step S121: in a first gateway cluster, selecting a first gateway with the largest number of communication links with a plurality of second gateways in a second gateway cluster, and establishing a preset communication link set corresponding to the first gateway;
step S122: and adjusting the sequence of the communication links in the preset communication link set according to the transmission time and/or the data capacity of the detection message in each communication link of the preset communication link set, so as to obtain the communication link set.
In this embodiment, the first gateway having the largest number of communication links with all the second gateways in the second gateway cluster is owned. And establishing a preset communication link set corresponding to the first gateway by selecting the communication link corresponding to the first gateway.
For example: the number of communication links between the first gateway a in the first gateway cluster and the second gateway cluster is the largest, and there are ten communication links, so a preset communication link set of the first gateway a is established, where there are ten communication links in the preset communication link set.
It is understood that the transmission time and data capacity of the detection message in each of the ten communication links may be the same or different. Therefore, the sequence of the communication links in the preset communication link set is adjusted according to the transmission time and the data capacity of the detection message in each communication link, so as to obtain the communication link set.
According to the technical scheme provided by the embodiment, the communication link set is determined according to two parameters, namely the transmission time of the detection message in each communication link and the data capacity during transmission. The method and the device realize the technical effect of quickly and efficiently acquiring the communication states of the two gateway clusters by quickly selecting the target communication link from the communication link set.
More specifically, in one possible implementation,
the first controller counts the number of communication links between each first gateway and each second gateway;
in the first gateway cluster, selecting a first gateway with the largest number of communication links in a second gateway cluster, and establishing a preset communication link set corresponding to the first gateway;
determining the time weight of each communication link according to the transmission time of the detection message in each communication link and the sum of the transmission times of all the communication links in a preset communication link set;
determining the data capacity weight of each communication link according to the data capacity of the detection message in transmission in each communication link and the sum of the data capacities of the detection message in transmission in all the communication links;
adjusting the sequence of communication links in a preset communication link set according to formula 1 to obtain a communication link set, wherein formula 1:
wherein the content of the first and second substances,
representing a time weight of the transmission of the detection message in the ith communication link,
representing a data capacity weight of the detection message when transmitted in the ith communication link;
in the set of communication links, the first controller selects a target communication link according to a communication link selection rule.
For example: there are three communication links in the preset communication link set, which are the first communication link, the second communication link and the third communication link. The transmission time of the detection message in the first communication link is 0.1s, the transmission time of the detection message in the second communication link is 0.2s, and the transmission time of the detection message in the third communication link is 0.3 s. Then, the time weight of the first communication link is 0.1/(0.1+0.2+ 0.3); the time weight of the second communication link is 0.2/(0.1+0.2+ 0.3); the time weight of the third communication link is 0.3/(0.1+0.2+ 0.3).
The data capacity of the detection message is 10 when transmitted in the first communication link, 12 when transmitted in the second communication link, and 15 when transmitted in the third communication link. Then, the data capacity weight of the first communication link is 10/(10+12+ 15); the data capacity weight of the second communication link is 12/(10+12+ 15); the data capacity weight of the third communication link is 15/(10+12+ 15).
And adjusting the sequence of the three links in the preset link set according to the time weight and the data capacity weight of the three links. That is, the calculation results were obtained by calculating 0.1/(0.1+0.2+0.3) +10/(10+12+15), 0.2/(0.1+0.2+0.3) +12/(10+12+15), and 0.3/(0.1+0.2+0.3) +15/(10+12+15), and the magnitudes of the three results were compared. It can be understood that the smaller the value corresponding to the time weight is, the less time is required when data is transmitted, and the faster the transmission speed is; the smaller the value corresponding to the data capacity weight is, the less time is required for transmitting data, and the faster the transmission speed is. Therefore, the three communication links in the communication link set are in the order of the first communication link, the second communication link, and the third communication link.
By the technical scheme provided by the embodiment, the sequence of a plurality of communication links in a preset communication link set is adjusted to obtain the communication link set. The method and the device have the advantages that the high-quality communication link is quickly selected from the communication link set to serve as the target communication link, and accordingly the technical effect of quickly and efficiently obtaining the communication state between the two gateway clusters is achieved.
Referring to fig. 4, fig. 4 is a schematic flowchart illustrating a method for detecting a communication status according to another embodiment of the present invention.
As shown in fig. 4, preferably, in one possible embodiment, the step S100 may further include:
step S140: selecting any second gateway from the second gateway cluster as a test second gateway;
step S150: obtaining a test communication link according to each first gateway and the test second gateway in the first gateway cluster;
step S160: performing a data packet test on each first gateway in the first gateway cluster through a test communication link to obtain a test result;
step S170: determining the response level of each first gateway in the first gateway cluster according to the test result;
step S180: selecting the target communication link according to the response level.
In this embodiment, there are ten first gateways in the first gateway cluster, and there are also ten second gateways in the second gateway cluster, and one test second gateway is selected from the ten second gateways. Ten test communication links are obtained, namely, one test communication link exists between each first gateway and each second gateway. And carrying out data packet test on each first gateway in the ten first gateways. It is understood that different first gateways may have different test results.
For example, among ten first gateways, the test results of two first gateways show that the response speed of the two first gateways is very high; the test results of the two first gateways show that the response speeds of the two first gateways are higher; the test results of two first gateways show that the response speeds of the two first gateways are general; and the test results of the four first gateways show that the response speed of the four first gateways is relatively slow.
Then, the response grade corresponding to the first gateway is determined according to the different response speeds of the different first gateways. It can be understood that the faster the response speed, the higher the response level of the first gateway. The communication link with the high response level is selected as the target communication link.
According to the technical scheme provided by the embodiment, the target communication link is selected according to the response level, so that the accuracy of selecting the target communication link is improved, and the technical effect of efficiently and accurately acquiring the communication state between the first gateway cluster and the second gateway cluster through the target communication link can be achieved.
Referring to fig. 5, fig. 5 is a flowchart illustrating a method for detecting a communication status according to another embodiment of the present invention.
As shown in fig. 5, the method includes:
step S100: the first controller selects a target communication link according to a preset communication link selection rule;
step S200: sending a detection message to the second controller over the target communication link;
step S300: determining a communication state between a first gateway cluster and a second gateway cluster according to a received feedback message sent by a second controller;
step S400: within a preset time threshold, if the first controller does not receive the feedback message, interrupting the target communication link;
step S500: calling a communication link corresponding to a first gateway with the minimum number of communication links with a second gateway cluster in the first gateway cluster;
step S600: the first controller forwards the detection message to the second controller according to the called communication link.
In this embodiment, within 5s of the preset time threshold, if the first controller does not receive the feedback message for feeding back the detection message, the target communication link for sending the detection message is directly interrupted. And in turn invokes other communication links to forward the detection message.
For example: the target communication link selected by the first controller is three communication links in the set of communication links. At clock 5s after the detection message is sent, no feedback message has been received. The detection message is no longer sent over the three communication links. And two communication links corresponding to the first gateway D are called to forward the detection message, where the first gateway D is the first gateway with the least number of communication links with the second gateway cluster among all the first gateways.
And if the first controller still does not receive the feedback message when the certain time is reached, reselecting the communication link. It will be appreciated that either communication link may be selected when the communication link is reselected. However, in order to further improve the efficiency, the communication link corresponding to the first gateway having the smallest number of communication links is selected.
For example, the target communication link selected by the first controller is four communication links in the communication link set. At clock 4s after the detection message is sent, no feedback message has been received. The detection message is no longer sent over the four communication links.
The first gateway C corresponds to three communication links, and the first gateway D corresponds to one communication link. Obviously, the time for forwarding the detection message to the first gateway C corresponding to three communication links is longer than the time for forwarding the detection message to the first gateway D corresponding to one communication link. In order to further save time and improve efficiency, the first controller calls the communication link corresponding to the first gateway with the least number of communication links of the second gateway cluster in the first gateway cluster, and forwards the detection message to the called communication link.
By the technical scheme provided by the embodiment, if the feedback message is not received within a certain time, the detection message is forwarded by replacing the communication link, so that the technical disadvantage that the detection message is repeatedly sent to cause waste of time and resources is avoided.
The detection message is forwarded in a mode of replacing the communication link, so that the communication states of the two gateway clusters are rapidly determined according to different communication links. The technical effect of rapidly and efficiently acquiring the communication states of the two gateway clusters is further achieved, and the accuracy and the reliability of the communication states of the two gateway clusters are ensured.
Referring to fig. 6, fig. 6 is a flowchart illustrating a method for detecting a communication status according to another embodiment of the present invention.
As shown in fig. 6, preferably, in a possible implementation manner, the step S110 further includes:
step S111: obtaining an initial number of communication links between each of the plurality of first gateways and each of the plurality of second gateways;
step S112: judging the packet loss rate of each communication link in the initial number and the size of a preset threshold, and deleting the communication links of which the packet loss rates are greater than the preset threshold;
step S113: the number of communication links is determined based on the initial number and the number of deleted communication links.
In this embodiment, when the first controller counts the number of communication links between each first gateway and each second gateway, the initial number is counted first.
For example: the initial number of communication links between the first gateway a and the second gateway B is three. And if the packet loss rate of the first communication link is greater than a preset threshold value, directly deleting the first communication link. And the packet loss rates of the other two communication links are smaller than a preset threshold value. Then, the number of communication links between the first gateway a and the second gateway B is determined to be two based on the initial number of three and the number of deleted communication links of one.
By the technical scheme provided by the embodiment, the communication links with high packet loss rate are screened in the initial quantity. The method and the device have the advantages that unnecessary flow loss is avoided, and the technical effect of efficiently and accurately obtaining the communication state between the two gateway clusters is achieved.
According to another aspect of the present invention, the embodiment of the present invention provides a communication status detection system corresponding to the above method.

As shown in fig. 7, the system includes: the gateway system comprises a first gateway cluster and a second gateway cluster, wherein the first gateway cluster comprises N first gateways and a first controller, the second gateway cluster comprises M second gateways and a second controller, at least one first gateway in the first gateway cluster and at least one second gateway in the second gateway cluster have a communication link, N and M are integers greater than 1, respectively, and the gateway system comprises:
