Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Fig. 1 is a schematic flowchart illustrating a gateway selection method in a multi-gateway environment according to an embodiment of the present invention, and referring to fig. 1, the method includes:
s11, the target gateway determines the contact strength between the target gateway and an upstream server, and obtains the contact strength between a first gateway and the upstream server, wherein the contact strength is an associated parameter index between the gateway and the upstream server, and the first gateway is at least one gateway in the same network environment with the target gateway;
and S12, the target gateway determines a main gateway according to the contact strength, wherein the main gateway is an execution gateway for transmitting the uplink and downlink data of the downstream equipment.
With reference to step S11, it should be noted that, in the embodiment of the present invention, the multi-gateway network environment refers to that there are multiple gateways that can be externally connected in the same communication space. Each gateway can determine the contact strength between the gateway and the upstream server, and the contact strength is an associated parameter index between the gateway and the upstream server. Such as signal strength and spatial distance. The greater the signal strength, the more closely the association between the corresponding gateway and the upstream server. The smaller the spatial distance, the more closely the association between the corresponding gateway and the upstream server is. Here, the related parameter index is not limited to the above-mentioned contents.
In embodiments of the present invention, the link strength is one or more of signal strength and spatial distance. But usually, one of the parameters is selected as the parameter index according to the method.
In an embodiment of the present invention, each gateway in a multi-gateway network environment may perform the method of the present embodiment to determine a primary gateway from the multi-gateways. The primary gateway is an executive gateway for transmitting downstream and upstream data of downstream devices.
The implementation of the method is explained below with respect to any gateway in the same network environment, and in the explanation, the gateway is regarded as a target gateway for convenience of content description. And at least one gateway in the same network environment with the target gateway is a first gateway.
In the embodiment of the invention, after determining the respective contact strength with the upstream server among the gateways, the respective contact strength can be shared among the gateways in a heartbeat packet broadcasting manner.
For this purpose, the target gateway may obtain the strength of contact between itself and the upstream server, and obtain the strength of contact between the first gateway and the upstream server.
And then, the target gateway determines a main gateway from the gateways according to the acquired contact strength between the target gateway and the upstream server and the contact strength between the first gateway and the upstream server.
In a further embodiment of the foregoing embodiment method, an explanation is made for a process in which the target gateway determines the primary gateway according to the contact strength, specifically as follows:
and the target gateway compares the contact strength between the target gateway and the upstream server with the contact strength between the first gateway and the upstream server to obtain a comparison result, and determines that the target gateway is the main gateway or determines that one gateway in the first gateway is the main gateway according to the comparison result.
For example, the link strength is a signal strength, and if the comparison result shows that the signal strength between the target gateway and the upstream server is stronger than the signal strength between each gateway in the first gateway and the upstream server, the target gateway is determined to be the master gateway. And if the comparison result shows that the signal strength between the target gateway and the upstream server is not completely stronger than the signal strength between each gateway in the first gateway and the upstream server, selecting the gateway with the strongest signal strength between each gateway in the first gateway and the upstream server as the main gateway.
For example, the strength of the connection is a spatial distance, and if the comparison result shows that the spatial distance between the target gateway and the upstream server is shorter than the spatial distance between each gateway in the first gateway and the upstream server, the target gateway is determined to be the master gateway. And if the comparison result shows that the space distance between the target gateway and the upstream server is not shorter than the space distance between each gateway in the first gateway and the upstream server, selecting the gateway with the shortest space distance between each gateway in the first gateway and the upstream server as the main gateway.
Here, when the target gateway determines itself to be the master gateway, since the other gateways also perform the above method, the other gateways can know that the target gateway is the master gateway. At this time, other gateways may be concerned whether the primary gateway shares the strength of contact when periodically sharing the strength of contact. The target gateway determines that one of the other gateways is a main gateway, that is, the target gateway is not a non-gateway, and at this time, the target gateway does not forward the uplink and downlink data of the downstream device to the upstream server after receiving the uplink and downlink data.
It should be further noted that when there are more than two gateways with the same contact strength, other conditions may be used to perform the auxiliary determination, such as selecting the gateway with a larger MAC address as the primary gateway, or selecting the gateway with a larger memory as the primary gateway.
The selection process of the primary gateway is explained in the following by using specific examples, and fig. 2 is a schematic diagram of the selection process of the primary gateway. Referring to fig. 2, there are A, B, C three gateways in a multi-gateway network environment, each of which remains connected to an upstream server and each of which can determine the strength of contact with the upstream server.
A. B, C the three gateways are kept in contact by heartbeat packets and communicate their respective strengths of contact with the upstream server.
At this time, the gateway a compares the contact strengths of the three gateways, finds that the contact strength between itself and the upstream server is optimal, and then itself becomes a master gateway, and the gateway B and the gateway C are non-master gateways.
At this time, the upstream and downstream data interacted between the downstream device and the upstream server are relayed by the main gateway a, and the gateways B and C are not relayed even if received.
According to the gateway selection method in the multi-gateway environment provided by the embodiment of the invention, the main gateway can be selected from all gateways according to the contact strength among the gateways in the multi-gateway environment, so that the main gateway can undertake the transmission work of the uplink and downlink data of the downstream equipment and the upstream server, and the situation that the upstream server receives the repeated data at the same time due to the fact that a plurality of gateways receive the downstream equipment and uplink the upstream server can be avoided.
Fig. 3 is a flowchart illustrating a gateway selection method in a multi-gateway environment according to an embodiment of the present invention, and referring to fig. 3, the method includes:
s21, the target gateway determines the contact strength between the target gateway and an upstream server, and obtains the contact strength between a first gateway and the upstream server, wherein the contact strength is an associated parameter index between the gateway and the upstream server, and the first gateway is at least one gateway in the same network environment with the target gateway;
s22, the target gateway determines a main gateway according to the contact strength, wherein the main gateway is an execution gateway for transmitting uplink and downlink data of downstream equipment;
s23, after the target gateway determines that the target gateway is the main gateway, the target gateway receives the contact strength between the new gateway and the upstream server, compares the contact strength between the target gateway and the upstream server with the contact strength between the new gateway and the upstream server to obtain a comparison result, and determines that the target gateway is the main gateway or determines that the new gateway is the main gateway according to the comparison result.
Regarding the step S21 and the step S22, these steps are basically the same as the step S11 and the step S12 of the above-described embodiment, and are not described again here.
With reference to step S23, it should be noted that, in the embodiment of the present invention, in a network environment with an existing gateway scale, if a new gateway joins, the determined primary gateway needs to compete with the new gateway to determine a new primary gateway. For this reason, the new gateway and the determined main gateway mutually share the contact strength between the new gateway and the upstream server.
And then, the target gateway compares the contact strength between the target gateway and the upstream server with the contact strength between the new gateway and the upstream server to obtain a comparison result, and determines that the target gateway is the main gateway or determines that the new gateway is the main gateway according to the comparison result.
If the target gateway is better in the comparison result, the target gateway continues to be used as the main gateway. And if the new gateway is better in the comparison result, the new gateway is used as a new main gateway.
The selection process of the primary gateway is explained in the following by using specific examples, and fig. 4 is a schematic diagram of the selection process of the primary gateway. Referring to fig. 4, there are B, C two gateways in a multi-gateway network environment, each of which is connected to an upstream server and each of which is capable of determining the strength of contact with the upstream server.
And B and C, the gateways keep contact through heartbeat packets and transfer respective contact strength with the upstream server.
At this time, the gateway B compares the contact strengths of the two gateways, finds that the contact strength between itself and the upstream server is optimal, and then becomes a master gateway, and the gateway C is a non-master gateway.
At this time, the uplink and downlink data interacted between the downstream device and the upstream server are relayed by the main gateway B, and the gateway C is not relayed even if received.
When gateway a comes online newly (i.e. newly joins or rejoins the network environment), and the contact strength with the upstream service is better than that of the current main gateway B.
At this time, a becomes the master gateway and B automatically cancels the master gateway.
According to the gateway selection method in the multi-gateway environment provided by the embodiment of the invention, the main gateway can be selected from all gateways according to the contact strength among the gateways in the multi-gateway environment, so that the main gateway can undertake the transmission work of the uplink and downlink data of the downstream equipment and the upstream server, and the situation that the upstream server receives the repeated data at the same time due to the fact that a plurality of gateways receive the downstream equipment and uplink the upstream server can be avoided.
Fig. 5 is a flowchart illustrating a gateway selection method in a multi-gateway environment according to an embodiment of the present invention, and referring to fig. 5, the method includes:
s31, the target gateway determines the contact strength between the target gateway and an upstream server, and obtains the contact strength between a first gateway and the upstream server, wherein the contact strength is an associated parameter index between the gateway and the upstream server, and the first gateway is at least one gateway in the same network environment with the target gateway;
s32, the target gateway determines a main gateway according to the contact strength, wherein the main gateway is an execution gateway for transmitting uplink and downlink data of downstream equipment;
s33, the target gateway determines that the contact strength between the main gateway and the upstream server is not received, and compares the contact strength between the target gateway and the upstream server with the contact strength between the second gateway and the upstream server to obtain a comparison result, wherein the main gateway is one of the first gateways, and the second gateway is the other gateway except the main gateway in the first gateway;
and S34, the target gateway determines that the target gateway is the main gateway or determines that one gateway in the second gateways is the main gateway according to the comparison result.
Regarding the step S31 and the step S32, these steps are basically the same as the step S11 and the step S12 of the above-described embodiment, and are not described again here.
With respect to step S33 and step S34, it should be noted that, in the embodiment of the present invention, in the current multi-gateway network environment, the target gateway is a non-primary gateway, and the primary gateway is one of the first gateways. When the current main gateway is switched off or is powered off, and the like, the main gateway contacts with the upstream service port, and at the moment, the main gateway does not share the contact strength any more. Therefore, the target gateway determines that the contact strength between the main gateway and the upstream server is not received, and compares the contact strength between the target gateway and the upstream server with the contact strength between the second gateway and the upstream server to obtain a comparison result. Here, the second gateway is the other gateway excluding the main gateway from the first gateway.
And then, the target gateway determines that the target gateway is the main gateway or determines that one gateway in the second gateways is the main gateway according to the comparison result.
Here, the primary gateway re-determination process is the same as the process described in the above embodiment, and is not described again here.
The selection process of the primary gateway is explained in the following by using specific examples, and fig. 6 is a schematic diagram of the selection process of the primary gateway. Referring to fig. 6, there are A, B, C three gateways in a multi-gateway network environment, each of which remains connected to an upstream server and each of which can determine the strength of contact with the upstream server.
A. B, C the three gateways are kept in contact by heartbeat packets and communicate their respective strengths of contact with the upstream server.
At this time, the gateway a compares the contact strengths of the three gateways, finds that the contact strength between itself and the upstream server is optimal, and then itself becomes a master gateway, and the gateway B and the gateway C are non-master gateways.
At this time, the upstream and downstream data interacted between the downstream device and the upstream server are relayed by the main gateway a, and the gateways B and C are not relayed even if received.
If the A gateway is disconnected or powered off, the connection with the upstream server is disconnected. The a gateway stops issuing heartbeat packets. The gateway B, C automatically compares the strength of contact after finding that a stops heartbeat packets, and selects a new primary gateway.
According to the gateway selection method in the multi-gateway environment provided by the embodiment of the invention, the main gateway can be selected from all gateways according to the contact strength among the gateways in the multi-gateway environment, so that the main gateway can undertake the transmission work of the uplink and downlink data of the downstream equipment and the upstream server, and the situation that the upstream server receives the repeated data at the same time due to the fact that a plurality of gateways receive the downstream equipment and uplink the upstream server can be avoided.
