Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With the development of smart homes, more and more smart products enter every family. In the related intelligent home systems, the equipment accessed to the intelligent home systems can send interactive data through the gateway. For example, when the cloud server needs to send a control instruction sent by the user terminal to a certain controlled device, the control instruction may be sent to a router in a certain local area network by the cloud server, then forwarded to the gateway by the router, and finally forwarded to the specific controlled device by the gateway. For another example, if the controlled device a needs to send a control instruction to the controlled device B, the control instruction may be forwarded by a gateway to which the controlled device a and the controlled device B are connected.
As the users use the smart home systems deeply, the number of devices accessing the smart home systems is increased, and in order to adapt to more devices, more gateways may be configured to transmit data between the devices. The inventor researches a network environment with multiple gateways, and finds that the network topology under the condition can be complex. For example, multiple gateways may or may not be in the same local area network. If the gateways are all in the same local area network, the gateways can directly communicate with each other. However, if the network has multiple sub-networks, due to the nature of ethernet, gateways present in different sub-networks may not be able to communicate with each other over the local network IP.
For example, as shown in fig. 1, there are 4 networks in the user environment, where there are two sub-networks under the 192.168.1.X network, which are: 192.168.2.X and 192.168.3.X.192.168.3.X network there is yet another subnetwork 192.168.4.100. The user now has 4 gateways, with gateway 1 in 192.168.1.X, gateway 2 in 192.168.2.X, gateway 3 in 192.168.3.X network, and gateway 4 in network 192.168.4. X.
Because the devices of the sub-network are invisible to the parent network due to the characteristics of the ethernet, the gateway of the parent network cannot connect to the gateway of the sub-network through the IP address when communicating. But the devices in the parent network are visible to the child network, so the devices of the child network can access the parent network through the IP address. Gateway 2, gateway 3 and gateway 4 may then all actively communicate with gateway 1, but gateway 1 cannot actively communicate with gateway 2, gateway 3 and gateway 4. The gateway 4 may actively communicate with the gateway 3, but the gateway 3 cannot actively communicate with the gateway 4. While devices between subnetworks may not communicate directly and thus gateway 2 may not communicate with gateway 3 or gateway 4. Likewise, gateways 3 and 4 cannot communicate directly with gateway 2.
The inventor finds in research that another related inter-gateway communication mode in a multi-gateway network is data forwarding through a cloud server. However, in this way of forwarding data through the cloud server, the data is heavily dependent on the cloud server, and the intermediate transmission network link is long, which results in a long data transmission delay and also fails to ensure the transmission security. Therefore, the method, the device, the system and the electronic equipment for multi-gateway communication are provided, wherein under the condition that a plurality of gateways automatically try to establish communication links among each other in advance and generate communication path information, when a point-to-point communication path among the gateways needs to be searched, the communication path information can be directly inquired, and the timeliness in determining the communication path and the efficiency of executing preset operation are improved. Moreover, the communication paths in the communication path information can be local communication paths, so that the dependence on the cloud server is reduced, and the data transmission efficiency and the data security are improved.
An application environment related to the embodiments of the present application will be described below.
As shown in fig. 2, in the application environment shown in fig. 2, a user terminal 100 and a communication system 200 are included. The user terminal 100 may perform data interaction with the communication system 200 through a network (e.g., a local area network or a wide area network, etc.). In one approach, the communication system 200 includes a cloud server 210, a first gateway 220, a second gateway 230, and a third gateway 240.
The cloud server 210 may serve as a relay station to forward data sent by the gateways, and may further store data of each of the first gateway 220, the second gateway 230, and the third gateway 240, where the data may include, for example, a packet and a network address to which each of the first gateway 220, the second gateway 230, and the third gateway 240 belongs. The first gateway 220, the second gateway 230, and the third gateway 240 may all belong to the same sub-network, may belong to different sub-networks, or may be located in networks having a parent-child relationship. For example, fig. 2 exemplarily shows that the network in which the third gateway 240 exists is a parent network of the network in which the first gateway 220 and the second gateway 230 exist.
It should be noted that fig. 2 is only an exemplary illustration of an application environment, the number of gateways in the figure may be increased or decreased as needed, and the affiliations (parent-child network relationships) of the networks may also be changed as needed.
Based on the above-described application environment and system, embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 3, a method for multi-gateway communication according to an embodiment of the present application includes:
step S110: the first gateway searches communication path information which comprises communication paths of communication connection which are established in advance between the first gateway and other gateways based on a specified communication protocol.
It should be noted that the first gateway may be understood as a gateway to perform a preset operation, and the second gateway may be understood as a target gateway corresponding to a target communication path to be determined subsequently. In the embodiment of the present application, each gateway may belong to one gateway group. As one way, one gateway group may be created in units of user homes. In this manner, a user may configure the gateway to associate with his account in order to group the network pipe. Furthermore, when a new gateway joins the gateway group, the cloud server assigns a unique identifier in the gateway group, called Id, to the new gateway.
Optionally, to facilitate the confirmation of the communication path, each gateway in the gateway group may locally store an address table and a forwarding table. The address table is used for recording the Ids and communication addresses of other gateways in a gateway group where the gateway is located; and the transfer table is used for recording the information of the communication path for the gateway to send the message to other gateways in the gateway group, wherein the information of the communication path comprises the related information of the transfer gateway and the time consumption of message transmission.
It is to be understood that the specified communication protocol refers to a communication rule that communication parties have agreed in advance, and may be simply understood as a common language used for mutual conversation between computers. The communication protocol has hierarchy, reliability and effectiveness. Optionally, the specified communication protocol mainly comprises a TCP/IP protocol.
As a manner, when the first gateway intends to perform a preset operation, and the preset operation relates to another gateway (for example, the aforementioned second gateway), the preset operation may be that the first gateway sends data to the second gateway according to a communication path, and when the first gateway needs to send data to the second gateway, the first gateway may first search its own local communication path information, where the communication path information includes a communication path between the first gateway and the second gateway, where a communication connection is established in advance based on a specified communication protocol, for example, information of the communication path stored in the aforementioned transfer table.
Step S120: and determining a target communication path between the second gateway and the second gateway from the communication paths.
In the embodiment of the present application, the target communication path with the second gateway may be determined in various ways.
As one approach, the first gateway may determine the target communication path based on the communication elapsed time. In this way, the first gateway compares the lengths of all communication paths by searching the communication path information corresponding to the first gateway, namely searching the transfer table of the first gateway, wherein the lengths of the communication paths are calculated by the time consumption of message transmission in the transfer table; and selecting the communication path with the shortest communication time as the target communication path.
Step S130: and executing preset operation.
It should be noted that the preset operation is a specific operation of communication between preset gateways.
As one way, the preset operation may be that the first gateway sends data to the target gateway through the target communication path.
According to the method for multi-gateway communication provided by the embodiment of the application, the first gateway searches the corresponding communication path information, then determines the target communication path between the first gateway and the second gateway from all the communication paths, and finally sends data to the target gateway through the target path. Therefore, the time consumption of data transmission between gateways is shortened; the strong dependence on the cloud server is reduced by establishing the transfer gateway to transmit data, the data are transmitted in the network of a user, the data transmission efficiency is improved, and the data security is improved.
Referring to fig. 4, a method for multi-gateway communication according to an embodiment of the present application includes:
step S210: the first gateway searches communication path information which comprises communication paths of communication connection which are established in advance between the first gateway and other gateways based on a specified communication protocol.
Step S220: and determining a target communication path between the second gateway and the communication path based on the communication elapsed time.
As one way, the step of determining a target communication path with the second gateway from the communication paths based on the communication elapsed time includes: and determining the communication path which consumes the least communication time as the target communication path from all the communication paths between the first gateway and the second gateway. The step of determining a communication path with the least communication time consumption as a target communication path in the communication paths between the first gateway and the second gateway comprises: firstly, judging whether a communication path between a first gateway and a second gateway is subjected to transit gateway or not; if so, taking the sum of the communication time consumption between the first gateway and the transit gateway and the time consumption between the transit gateway and the second gateway as the communication time consumption of a communication path between the first gateway and the second gateway; and determining a communication path which consumes the least time for corresponding communication in the communication paths between the second gateway and the second gateway as a target communication path.
Optionally, when the preset operation is to send data, the first gateway may query the relay table, and compare the route that consumes the shortest time among all communication routes of the relay table to send data. For example, taking the gateway 1 as a first gateway to send data to the gateway 2 as a second gateway as an example, in the following forwarding table, when the gateway 1 needs to send data to the gateway 2, the gateway 1 will look up its forwarding table and find out which gateway should forward the message addressed to the gateway 2. If a corresponding intermediary is found, such as the gateway 3, the message is sent directly to the gateway 3.
Similarly, when the gateway 2 needs to send data to the gateway 1, the gateway 2 looks up the transfer table therein to find that the transfer can be performed by the gateway 3. The gateway 2 transmits the data transmitted to the gateway 1 to the gateway 3. After receiving the data, the gateway 3 sends the data to the gateway 1.
Figure BDA0002237973690000081
Figure BDA0002237973690000091
Illustratively, as shown in the above table, the gateway 1 sends data to the gateway 2, and by finding out the transfer table of the gateway 1, the gateway 1 can send data to the gateway 2 through the transfer gateway 3, or can directly send data to the gateway 2 by itself; the time consumed for gateway 1 to send data to gateway 2 through transit gateway 3 is 10+10=20ms, the time consumed for gateway 1 to directly send data to gateway 2 is 5ms, and by comparison, a communication path with communication time consumed as 5ms can be used as a target communication path.
As a mode, if the first gateway does not find a target communication path for transmitting data with the second gateway from the communication path, the data sent to the second gateway may be sent to the cloud server, and forwarded to the second gateway through the cloud server.
Step S230: and if the first gateway detects that the updated gateway exists in the gateway group to which the first gateway belongs, updating a locally stored gateway list of the gateway group to which the first gateway belongs, wherein the gateway list comprises the unique identifier of each gateway and the corresponding IP address.
It should be noted that, in the home system, as the user requirement changes, the devices added into the gateway group change at any time, so that all the gateway information in the corresponding gateway group needs to be updated according to the change of the devices in the gateway group, for example, if a terminal device is suddenly added or deleted, the gateway in the gateway group needs to update the gateway information correspondingly. In this embodiment, the first gateway may perform the relevant update operation based on a variety of ways.
As a mode, if the first gateway detects that there is an updated gateway in the gateway group to which the first gateway belongs, the step of updating the locally stored gateway list of the gateway group to which the first gateway belongs includes: a first gateway receives a gateway list of a gateway group which the cloud server belongs to; and then the first gateway detects the received gateway list, and if the updated gateway is detected in the gateway list, the locally stored gateway list of the gateway group to which the first gateway belongs is updated.
Optionally, the gateway having an update in the gateway group includes the following two cases, one is when a new gateway is added or deleted in the gateway group, and the other is when an address of the gateway is updated in the gateway group. Both of these situations may result in the cloud server updating the gateway address table and pushing the updated gateway address table to all online gateways in the gateway group. When the gateway in the gateway group receives the gateway address table pushed by the cloud server, updating the content of the local gateway address table: if the gateway address item is newly added, trying to establish connection with the newly added gateway; if the gateway address entry is deleted, clearing the entry of the transfer table related to the gateway; if the gateway address entry is changed, the entry of the transfer table associated with the gateway is cleared and an attempt is made to establish a connection with the use address.
Illustratively, in the original gateway group, only gateway 1 and gateway 2 are present, and gateway 3 now joins the gateway group and informs the cloud server of its own network address. The cloud server receives the network address of the gateway 3 and assigns an Id of 3 to the gateway 3. The cloud server then updates the gateway address table and pushes the new gateway address table to all gateways in the gateway group. When gateway 3 receives the gateway address table, two other gateways are found. It then updates its local gateway address table and creates a corresponding entry in the local transit table for each other gateway. When the gateway 1 receives the gateway address table, it finds that the gateway 3 is newly added, updates the local gateway address table, and adds the address item of the gateway 3 in the transfer table.
By updating the gateway address table and the transfer table information in real time, the effectiveness of real-time communication between gateways can be ensured, the timeliness when a communication path is determined is also improved, and the efficiency of data transmission is further improved.
Step S240: and sending a communication connection request to the updated gateway based on the IP address of the updated gateway, and updating the communication path information corresponding to the first gateway based on the result of the communication connection request.
As one mode, the step of sending a communication connection request to the updated gateway based on the updated IP address of the gateway, and updating the communication path information corresponding to the first gateway based on the result of the communication connection request includes: sending a communication connection request to the updated gateway based on the IP address of the updated gateway, and starting a timer to start timing; if receiving information returned by the updated gateway, acquiring the timing length of the timer when the returned information is received, and determining the timing length as the communication time consumed by the first gateway to send data to the updated gateway; and updating the communication path information corresponding to the first gateway based on the communication time consumption of the first gateway for sending data to the updated gateway.
As another mode, if the first gateway receives information returned by the updated gateway, confirmation information is returned to the updated gateway, so that the updated gateway determines that the communication between the updated gateway and the first gateway is time-consuming, so as to update the corresponding communication path information.
It can be understood that, after the first gateway changes its own address table, it starts to attempt to establish a connection with the second gateway, and in the process of attempting the connection, the first gateway sends a visit request to the second gateway, where the visit request content includes: { Id of first gateway, id of second gateway }. The second gateway sends a visit reply to the first gateway after receiving the request, wherein the reply content comprises: { gateway Id, communication time consumption }. And after receiving the visit reply of the second gateway, the first gateway replies a visit confirmation to the second gateway.
Illustratively, as shown in the following table, in the original gateway group, only gateway 1 and gateway 2 are present, gateway 3 now joins the gateway group, and gateway 3 informs the network address of the cloud server itself. After receiving the network address of the gateway 3, the cloud server may further assign an Id of 3 to the gateway 3. The cloud server then updates the gateway address table and pushes the new gateway address table to all gateways in the gateway group. When gateway 3 receives the gateway address table, two other gateways are found. Then, the gateway 3 will further update its local gateway address table and create a corresponding entry in the local transfer table for each other gateway, where the corresponding entry includes the gateway Id and the communication time. When the gateway 1 receives the gateway address table, it finds that the gateway 3 is newly added, updates the local gateway address table, and adds the address item of the gateway 3 in the transfer table.
Gateway Id Gateway address
1 192.168.1.10
2 192.168.3.44
3 192.168.1.6
Gateway 1 then attempts to establish a connection with gateway 3. The gateway 1 sends a visit request to the gateway 3, and the information comprises: { Id of gateway 1, id of gateway 3 }. After sending the visit request, the gateway 1 starts timing and waits for the visit reply of the gateway 3.
After the gateway 3 receives the request, the gateway 3 searches the local transfer table, finds out other directly connected gateway information, generates an exchange table, and replies to the gateway 1. The switching table contains the contents: { gateway Id, communication time consumption }. At this time, no other gateway is connected to the transfer table in the gateway 3. The switching table has no data. The gateway 3 starts timing after transmitting the switching table, and waits for the visit confirmation of the gateway 1.
After receiving the reply from the gateway 3, the gateway 1 obtains the time interval, for example, 5ms, for communicating with the gateway 3 through the timer, and updates its own transfer table.
Gateway 1 then replies with an acknowledgement message to gateway 3. After receiving the visit confirmation, the gateway 3 obtains a time interval, for example, 8ms, by using a timer, and updates its own transit table.
In the same way, the gateway 2 updates its forwarding table in this way. When the gateway 2 receives the gateway address table, the gateway 3 is newly added, so that the local gateway address table of the gateway is updated, and the address item of the gateway 3 is added in the transfer table; and then attempts to establish a connection with the gateway 3.
The gateway 2 sends a visit request to the gateway 3, and the information comprises: { Id of gateway 2, id of gateway 3 }. After sending the visit request, the gateway 2 starts timing and waits for the visit reply of the gateway 3. After the gateway 3 receives the request, the gateway 3 looks up the local transfer table to find out other directly connected gateway information, wherein the gateway 1 directly communicates with the gateway, generates an exchange table and sends the exchange table to the gateway 2.
The gateway 3 starts timing after sending the switching table to the gateway 2, and waits for the visit confirmation of the gateway 2. After receiving the reply from the gateway 3, the gateway 2 obtains the time interval, for example, 6ms, for communicating with the gateway 3 through a timer, and updates its forwarding table. The gateway 2 then replies with an acknowledgement message to the gateway 3.
After receiving the visit confirmation, the gateway 3 obtains a time interval, for example, 3ms, by using a timer, and updates its own transit table. Since there is a transit table item in the gateway 3 changed, the gateway 3 packs the changed data into a transit table and forwards the transit table to all directly connected gateways. Gateway 3 then sends a switching table update request to gateway 1. After receiving the switching table updating request, the gateway 1 updates its own transfer table.
All gateways establish the connection among each other by updating their transfer tables, so that the transfer tables of the gateway 1, the gateway 2 and the gateway 3 all have paths for data to be sent to other gateways.
Step S250: and the first gateway synchronizes the updated communication path information with the gateway which establishes the communication connection so as to update the corresponding communication path information with the gateway which establishes the communication connection with the first gateway.
It is understood that after the first gateway and the second gateway establish a connection, data can be transmitted between the two gateways.
Step S260: and executing preset operation.
According to the multi-gateway communication method provided by the embodiment of the application, a first gateway tries to establish connection with a second gateway, then the first gateway and the second gateway update own gateway lists according to a visit request, a visit reply and a visit confirmation message sent between the first gateway and the second gateway, confirm communication paths for transmitting data between the first gateway and the second gateway, then select the path with the least communication time consumption as a target path by comparing the communication time consumption of the communication paths, and finally transmit the data according to the target path. Therefore, the time consumption of data transmission between gateways is shortened; the strong dependence of the gateway on the cloud server is reduced by establishing the transfer gateway for transmitting data, and after the transfer gateway is established, the gateway can not forward the data through the cloud server, the data is transmitted in the network of the user, and the safety of data transmission is improved.

Both of these situations may cause the cloud server to update the gateway address table and push the updated gateway address table to all online gateways in the gateway group. When the gateway in the gateway group receives the gateway address table pushed by the cloud server, updating the content of the local gateway address table: if the gateway address item is newly added, trying to establish connection with the newly added gateway; if the gateway address entry is deleted, clearing the entry of the transfer table related to the gateway; if the gateway address entry is changed, the entry of the transfer table associated with the gateway is cleared and an attempt is made to establish a connection with the use address.

Step S460: the first gateway determines a target communication path with a second gateway in the gateway group based on the updated communication path information.
Wherein the determining the policy of the target communication path comprises: firstly, judging whether a communication path between a first gateway and a second gateway is to pass through a transit gateway or not; if so, taking the sum of the communication time consumption between the first gateway and the transit gateway and the time consumption between the transit gateway and the second gateway as the communication time consumption of a communication path between the first gateway and the second gateway; and determining the communication path which consumes the least time for corresponding communication in the communication paths between the second gateway and the second gateway as a target communication path.
