It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings.
It should be further noted that, for convenience of description, only some, but not all of the matters related to the present application are shown in the accompanying drawings. Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently, or at the same time. Furthermore, the order of the operations may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example 1
Fig. 1 is a flowchart of a cross-network communication method according to an embodiment of the present application, where the embodiment is applicable to a case of performing cross-network communication, the method may be performed by a cross-network communication device according to an embodiment of the present application, and the device may be implemented in a software and/or hardware manner. As shown in fig. 1, the method specifically includes the following operations:
step S101, receiving communication data sent by a first central node in a first network where the communication data currently resides.
Specifically, as shown in fig. 2, in the application scenario of the communication method in this embodiment, the network a and the network B are adjacent local area networks with an overlapping area, each network includes a plurality of common nodes and a central node, in this embodiment, one common node may be selected from the overlapping area as a gateway through initialization configuration, central node assignment, or by adopting an election mechanism, and in this embodiment, a specific manner of determining the gateway from the common nodes in the overlapping area is not limited. In the present embodiment, the first network may be the first network, the second network may be the second network, and the first network may be the second network, or the first network may be the first network.
Optionally, the method further comprises: determining a resident switching strategy, wherein the resident switching strategy comprises timing switching; and carrying out periodical resident switching in the first network and the second network through a resident switching strategy, wherein the gateway is identical to the resident network in working frequency point, and the working frequency points of the first network and the second network are different.
It should be noted that, the gateway in this embodiment may perform handover between two adjacent networks, specifically, by determining a park handover policy, for example, performing network park handover every 1 minute, and performing periodic handover in the first network and the second network according to the determined park handover policy. Because the working frequency points of the first network and the second network are different in this embodiment, the gateway is realized by changing its own working frequency point when performing residence switching, and when the gateway residence switches to the first network, the gateway is switched to the working frequency point of the first network, so that the gateway maintains time synchronization with the first network and maintains a communication link with a first central node in the first network, and the gateway and the second network are in a disconnection state; when the gateway is at the end of the residence time of the first network and is switched to the working frequency point of the second network, a communication link is kept between the gateway and the second central node in the second network, the gateway is in a disconnection state with the first network, and the central nodes in the networks need to maintain the switching time information of the gateway.
Optionally, before receiving the communication data sent by the first central node in the first network where the first network currently resides, the method further includes: when determining to reside in the second network, periodically receiving second network node information issued by a second central node in the second network, wherein the second network node information comprises identifiers of all nodes in the second network; generating a node update message when the node in the second network is determined to be changed according to the periodically received second network node information, wherein the node update message comprises an update node identifier and an update operation, and the update operation comprises adding or deleting; when determining that the residence is switched to the first network, sending a node update message to a first central node, and broadcasting the update message to all nodes in the first network through the first central node so that all nodes update a node information table of the node according to the update message, wherein the node information table comprises all node identifiers in the current first network and all node identifiers in the second network.
In this embodiment, when the node a in the first network needs to perform cross-network transmission to the node b in the second network, the precondition that the node a knows that the node b exists in the second network, and if the node b has been deleted and the node a is not aware, the cross-network transmission is invalid, so that in order to ensure the validity of the cross-network transmission, the first network and the second network in this embodiment share node information. For example, in this embodiment, taking the node a to obtain node information in the second network as an example, when the gateway resides in the second network, since each node in the second network is notified to the second central node in the second network when the gateway enters or exits the network, the second central node may obtain information of all nodes in the second network, that is, the second network node information, and include the identifiers of all nodes in the second network, and since the gateway periodically receives the second network node information sent by the second central node, when the gateway determines that the node in the second network changes according to the periodically received second network node information, a node update message is generated, and a format of the node update message is specifically shown in table 1 below:
TABLE 1
MsgType Network ID Adding node number Node ID list Deleting the number of nodes Node ID list
When the gateway detects that node information in the second network changes, the gateway initiates different network node information sharing, so that when the gateway is determined to be resident and switched to the first network, node update information is sent to the first center node, the first center node broadcasts the update information to all nodes in the first network, each node updates its own node information table according to the update information, namely, node a in the first network can acquire which nodes are specifically included in the current second network, and in addition, the first center node in the first network also broadcasts the node information of the first network periodically in the first network, so that node a can acquire all node identifiers in the current first network and update the node information table, and under the condition that node b exists in the second network, node a in the first network can acquire in time through different network node information sharing.
Optionally, receiving communication data sent by a first central node in a first network where the communication data currently resides includes: receiving communication data directly transmitted by a first central node in a first network where the first central node currently resides, wherein the communication data is transmitted by a source node when a gateway resides in the first network; or receiving communication data extracted from the local cache by a first central node in the first network where the first central node currently resides, wherein the communication data is sent to the first central node by a source node when the gateway resides in the second network.
In one embodiment, when the node a in the first network needs to communicate across networks, the node information table is searched to obtain that the destination node b is the second network, communication data is generated, and the communication data is sent to the first central node in the first network, where the format of the communication data is as shown in the following table 2:
TABLE 2
MsgType Source network ID Source node ID Destination network ID Destination node ID Data payload
The communication data comprises a source network identifier, a source node identifier, a destination network identifier, a destination node identifier and a data load, and the data load contains data to be transmitted. After receiving the communication data, the first central node further detects whether the gateway is currently resident in the first network when detecting that the destination node b is a node in the second network, if so, the communication data is directly transmitted to the gateway, otherwise, the communication data is stored in a local cache, and when determining that the gateway is resident and switched to the first network, the communication data is extracted from the local cache and is transmitted to the gateway. Therefore, it can be known that the gateway in this embodiment may directly receive the communication data sent by the first central node, or may first wait for the first central node to extract the communication data from the local cache and then receive the communication data sent by the first central node.
Step S102, when the communication with the second network is determined to be needed according to the target node identification, the communication data are stored in a target cache queue.
Optionally, when it is determined that communication with the second network is required according to the target node identifier, storing the communication data in a target cache queue, including: when the target node is located in the second network according to the target node identification, determining that communication with the second network is needed; determining a first cache queue and a second cache queue which are pre-configured, wherein the first cache queue is used for storing data transmitted to the second network by the first network, and the second cache queue is used for storing data transmitted to the first network by the second network; screening from the first cache queue and the second cache queue according to a second network for receiving data, and taking the first cache queue as a target cache queue; and saving the communication data in a target cache queue.
Specifically, in this embodiment, when the gateway obtains the communication data, it is determined that the target node is a node in the second network according to the target node identifier in the communication data, and it is determined that communication with the second network is required. And therefore, when the gateway determines that the data needs to be transmitted from the first network to the second network according to the communication data, the first cache queue is used as a target cache queue.
It should be noted that, in this embodiment, the space sizes of the first buffer queue and the second buffer queue are not limited, and the user may configure according to actual needs. In this embodiment, the manner of determining the target buffer queue is illustrated only when the first network is implemented to cross-network transmission to the second network through the gateway, and when the second network is implemented to cross-network transmission to the first network through the gateway, the manner of determining the target buffer queue is substantially the same as that, and no description is given in this embodiment.
Step S103, when the residence is switched to the second network, the communication data in the target cache queue is sent to a second central node in the second network, so that the second central node sends the data to be transmitted to a target node in the second network according to the target node identification.
Optionally, sending the communication data in the target cache queue to a second central node in a second network, including: detecting a target cache queue, and extracting communication data stored in the target cache queue when the data in the target cache queue is detected; the extracted communication data is sent to a second central node within a second network.
Specifically, when the gateway is in the second network, the first central node in the first network is returned to be disconnected to interrupt the communication link and maintain the communication link with the second central node in the second network, and when the gateway is in the second network, the first cache queue, which is the target cache queue, is detected, and when the data in the target cache queue is determined, the communication data stored in the target cache queue is sent to the second central node in the second network. Because the communication data records the target node identifier such as the node b and related information such as the data to be transmitted, the second central node sends the data to be transmitted to the target node, namely the node b, in the second network, thereby completing the cross-network transmission from the node a in the first network to the node b in the second network.
In the present embodiment, the first network a is taken as a first network, and the second network B is taken as a second network, and the first network performs cross-network data transmission to the second network. Of course, the network a may be used as the second network, and the network B may be used as the first network, and the specific transmission originals are substantially the same as those described above, so that a detailed description is omitted in this embodiment.
According to the technical scheme of the embodiment of the application, one gateway is selected from the nodes in the overlapping area of the first network and the second network, and the data transmission in different networks is realized through the resident switching mechanism of the gateway, so that the node communication in adjacent different networks is realized without adding additional hardware equipment, and the hardware cost is remarkably saved.
Example two
Fig. 3 is a flowchart of a cross-network communication method according to a second embodiment of the present application, where the method further includes detecting a cross-network communication result after sending communication data in a target buffer queue to a second central node in a second network based on the above embodiment. Correspondingly, the method of the embodiment specifically comprises the following operations:
step S101, receiving communication data sent by a first central node in a first network where the communication data currently resides.
Optionally, before receiving the communication data sent by the first central node in the first network where the first network currently resides, the method further includes: when determining to reside in the second network, periodically receiving second network node information issued by a second central node in the second network, wherein the second network node information comprises identifiers of all nodes in the second network; generating a node update message when the node in the second network is determined to be changed according to the periodically received second network node information, wherein the node update message comprises an update node identifier and an update operation, and the update operation comprises adding or deleting; when determining that the residence is switched to the first network, sending a node update message to a first central node, and broadcasting the update message to all nodes in the first network through the first central node so that all nodes update a node information table of the node according to the update message, wherein the node information table comprises all node identifiers in the current first network and all node identifiers in the second network.
Optionally, receiving communication data sent by a first central node in a first network where the communication data currently resides includes: receiving communication data directly transmitted by a first central node in a first network where the first central node currently resides, wherein the communication data is transmitted by a source node when a gateway resides in the first network; or receiving communication data extracted from the local cache by a first central node in the first network where the first central node currently resides, wherein the communication data is sent to the first central node by a source node when the gateway resides in the second network.
Step S202, when the communication with the second network is determined to be needed according to the target node identification, the communication data are stored in the target cache queue.
Optionally, when it is determined that communication with the second network is required according to the target node identifier, storing the communication data in a target cache queue, including: when the target node is located in the second network according to the target node identification, determining that communication with the second network is needed; determining a first cache queue and a second cache queue which are pre-configured, wherein the first cache queue is used for storing data transmitted to the second network by the first network, and the second cache queue is used for storing data transmitted to the first network by the second network; screening from the first cache queue and the second cache queue according to a second network for receiving data, and taking the first cache queue as a target cache queue; and saving the communication data in a target cache queue.
Step S203, when the residence is switched to the second network, the communication data in the target cache queue is sent to a second central node in the second network, so that the second central node sends the data to be transmitted to the target node in the second network according to the target node identification.
Optionally, sending the communication data in the target cache queue to a second central node in a second network, including: detecting a target cache queue, and extracting communication data stored in the target cache queue when the data in the target cache queue is detected; the extracted communication data is sent to a second central node within a second network.
Step S204, detecting whether a receiving response fed back by the second center node is received within a specified time range, if yes, executing step S205, otherwise executing step S206.
Specifically, when the target node receives the communication data, the target node feeds back a receiving response to the second center node and sends the receiving response to the gateway through the second center node; in the case that the target node does not receive the communication data, no receiving response is generated, so in this embodiment, the gateway may detect whether the receiving response fed back by the second central node is received within a specified time range, for example, 3 seconds.
Step S205, determining that the transmission of the communication data across the network is successful.
Step S206, determining the transmission failure of the communication data across the network and generating the prompt information of the communication failure across the network.
Specifically, when it is determined that the receiving response is not received within 3 seconds, the current cross-network communication failure is determined, and at this time, cross-network communication failure prompt information is generated, and the cause of the cross-network communication failure may be that the target node fails in hardware or that the second central node fails in a communication link with the target node.
The gateway can display the cross-network communication failure prompt information to the user, so that the user can detect hardware equipment or a network in time according to the prompt information, and the efficiency and the accuracy of the cross-network communication are further ensured.
According to the technical scheme of the embodiment of the application, one gateway is selected from the nodes in the overlapping area of the first network and the second network, and the data transmission in different networks is realized through the resident switching mechanism of the gateway, so that the node communication in adjacent different networks is realized without adding additional hardware equipment, and the hardware cost is remarkably saved.
