Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
It should be noted that although functional block division is performed in a device diagram and a logic sequence is shown in a flowchart, in some cases, the steps shown or described may be performed in a different order than the block division in the device, or in the flowchart. The terms first, second and the like in the description and in the claims and in the above-described figures, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
In the field of communication technology, especially in industrial ethernet, the transmission path of the device domain or the device group with the same operation attribute is often determined, but when the device domain or the device group is built, each device in the device domain or the device group is often required to be considered to be configured or an inherent transmission mode is adopted to configure instruction transmission with different operation attributes. In this way, waste of network resources or increase of labor cost is often caused, and therefore, a flexible service message transmission manner is needed to reduce network operation cost. Based on the above, the embodiment of the application provides a service message transmission method, a system, a device and a storage medium, which can provide a flexible service message transmission mode to reduce the network operation cost.
The method of the embodiment of the application is further described below with reference to the accompanying drawings.
Referring to the flowchart shown in fig. 1, an embodiment of the present application further provides a service packet transmission method, applied to a first network node, where the method includes:
step S100, obtaining a logic transmission path; the logic transmission path is determined from a transmission path list by the first network node according to the transmission characteristics of the first channel group; the first channel group includes a first network node.
It should be noted that the transmission path list is preset and includes a plurality of supported logic transmission paths. The logic transmission path may be set when the member node of the first channel group is initialized according to the configuration parameters of the first channel group loaded in the configuration file, or may be set when the node is initialized, and the logic transmission path is effective after the first channel group is set. In other embodiments, the logical transmission paths are generated by user dynamic configuration.
It should be noted that the first network node may be a first master network node or one of a plurality of first slave network nodes of a first channel group, where the first channel group is formed by the first master network node and the plurality of first slave network nodes.
It should be noted that, the transmission characteristic represents a service function attribute of the first channel group supporting processing, if the first channel group is used for collecting data, the data is collected as the transmission characteristic, and the first channel group is used as the controller to issue a signal instruction, and is controlled by the first master network node to issue, and the first slave network receives the signal instruction to process or process and respond to the signal instruction as the transmission characteristic. I.e. the transmission characteristics comprise the transmission direction and response parameters of the signal commands of the first channel group.
Step 200, determining a transmission direction and response parameters of the first service message according to the logic transmission path and the first routing table.
It should be noted that the first routing table may determine an actual transmission path of each first network node according to the logical transmission path. Therefore, the service transmission paths matched with different application scenes can be planned by defining logical transmission paths on logic and combining the first routing table.
It should be noted that, each logic transmission path corresponds to a transmission direction of the first service packet and a response manner, and at this time, the first service packet corresponding to each signal instruction in the first channel group is processed and responded according to the transmission direction.
It should be noted that the transmission direction indicates from which point the first message originates, e.g. from the first master network node or from the first slave network node.
It should be noted that, the response parameter means two meanings, one is whether the member node of the first channel group that receives the signal instruction needs to analyze and process, and the other is, as the destination address of the signal instruction, whether the member node needs to respond to the initiator of the signal instruction.
Step S300, according to the transmission direction, the first service message is transmitted and the first service message is processed according to the response parameter.
Therefore, by setting the logic transmission paths in one-to-one correspondence with the transmission characteristics of the first channel group, different first channel groups can select the pre-matched logic transmission paths, and further determine the transmission direction and response parameters of the first service message, and at this time, for the first channel group, only the logic transmission paths are required to be acquired and combined with the first routing table to realize flexible matching in different physical topologies, so that compared with the traditional manual configuration or interaction by adopting a fixed transmission mode, the embodiment of the application can provide a flexible service message transmission mode to reduce the network operation cost.
Illustratively, referring to the embodiment shown in fig. 2, taking the first channel group G1 as an example, the first master network node is B, and the plurality of slave network nodes are A, C, D, E, respectively. When the transmission direction determined by the logic transmission path is B, as the initiating direction A, C, D, E, a signal instruction is sent, and the response parameter is A, C, D, E, after receiving the signal instruction, the signal instruction is analyzed, and no response is needed. Then, when a signal command from the first master network node B is received at A, C, D, E, the signal command is parsed, and after the processing is completed, the next signal command from the first master network node B is waited. At this time, A, C, D, E does not need to respond, A, C, D, E does not need to issue a signal command to the first main network node B, and negotiation related to signal command processing is not required between A, C, D, E, so that compared to the conventional method that relies on the first main network node B to issue and must respond to the first main network node, the bandwidth utilization is higher in the embodiment of the present application.
It is understood that the transmission path list includes a single-chain transmission path and a star-shaped transmission path.
It should be noted that, the single-chain transmission path and the star-shaped transmission path are both logical transmission sequences, the single-chain transmission path indicates that the initiator of the first service packet is a first master network node, and the plurality of first slave network nodes sequentially analyze and process the signal instruction from the first master network node and transmit the signal instruction to the next slave network node, so that after the first master network node sends the signal instruction, the signal instruction can be received by each first slave network node. And each first slave network node need not respond to whether the signal instruction is received. Or need not respond to the completion of execution of the signal instruction result.
It should be noted that the star transmission path indicates that the initiator is the first slave network node, and the first master network node does not need to respond to the signal instruction sent by the first slave network node.
It can be understood that the logic transmission path is a single-chain transmission path, and step S200 of determining, according to the logic transmission path, a transmission direction and a response parameter of the first service packet includes: according to the first routing table, carrying out shortest path planning on a first master network node and a plurality of first slave network nodes of a first channel group to obtain a first path; wherein the first network node is a first master network node; the first node of the first path is a first main network node; taking the direction from the head node to the end node in the first path as a transmission direction; and analyzing and processing the first service message at the first slave network node as a response parameter.
It should be noted that, for each member node of the first channel group, a corresponding routing table is set. Illustratively, referring to the embodiment shown in fig. 2, the first master network node B is provided with a first routing table, and the first slave network node A, C, D, E is provided with a second routing table, where the destination addresses recorded in the routing table entries in both the first routing table and the second routing table are the same. Thus, in the case of unchanged physical topology, the resulting first path is coincident with the shortest path each member node plans to make the next hop, according to the first routing table.
It should be noted that, in the single-chain transmission path, the transmission direction is a direction in which the first node sequentially passes through several intermediate nodes of the first path to reach the end node, and, for example, referring to the embodiment shown in fig. 3, the logic transmission path is B- > a- > C- > D- > E. At this time, each of the first slave network nodes A, C, D, E only parses the signal command and does not transmit the response data back to the first master network node B. It should be noted that, since the single-chain transmission path is a logical transmission sequence, in the actual transmission process, there is one first slave network node that is passed through N times, for example, referring to the embodiment shown in fig. 2 and 3, the first slave network node is passed through N times, so that D, E can both receive, that is, the corresponding actual transmission sequence is B- > a- > C- > a- > D- > a- > B- > E. At this time, a performs transparent forwarding on the signal instruction according to the set logic transmission path when it is perceived that the signal instruction has been executed.
It is appreciated that the transmission efficiency of the first master network node is higher than the number of first slave network nodes.
It can be understood that the transmission efficiency includes the total forwarding times of the first service packet reaching each first slave network node, and the number of third network nodes passing through the first network domain when reaching the first slave network node.
It should be noted that, in some embodiments, the first main network node is obtained by automatic election, after the first channel group is created, each first channel is planned under a single-chain transmission path, and the number of times of forwarding reaching the end node of the first channel is taken as the total number of times of forwarding, where at this time, each first network node of the first channel group may obtain a total number of times of forwarding, and the total number of times of forwarding may be mutually transmitted, so that the highest number of times of forwarding obtained in total may be determined.
It should be noted that, in some embodiments, referring to the embodiment shown in fig. 2, the first channel group G1 is located in the first network domain Q1, and at this time, the third network node includes H, F, G, K.
It should be noted that, in some embodiments, a weight is set for the total forwarding number and the number of the third network nodes, and a transmission efficiency is calculated according to the weight and compared with the transmission efficiency. In other embodiments, the total forwarding times may be sorted from small to large, and the minimum number of third network nodes in the top several network nodes may be used as the highest transmission efficiency.
It is understood that the method further comprises: writing the first path into a first service message so that a second network node receiving the first service message forwards the first service message according to the first path, wherein the first network node is a first main network node.
It should be noted that, the first path is saved to the first service packet, so as to further ensure that the second network node that receives the first service packet can determine the path plan of the next hop according to the node information in the first path, if the destination address of the first service packet is C, the second network node that currently receives the first service packet is a, on the first path, the next hop of a is B, the second network node a will extract the information B of the next hop from the first service packet, and plan the path to B according to the routing table in the second network node, so that the first service packet must reach C after sequentially passing through the points on the first path.
It should be noted that, in this way, the probability of misjudgment of the transmission situation of the nodes of the first channel group in one network domain can be reduced. For example, the member nodes of the first channel group are logically nodes, and at least one member node not belonging to the first channel group exists between two member nodes.
It can be understood that the logic transmission path is a star-shaped transmission path, and step S200 of determining, according to the logic transmission path and the first routing table, a transmission direction and response parameters of the first service packet includes: planning a shortest path from the first network node to a first main network node of the first channel group according to the first routing table; wherein the first network node is one of a plurality of slave network nodes of the first channel group; taking the transmission direction from the head node to the tail node of the shortest path as the transmission direction; and analyzing and processing the first service message only at the first main network node as a response parameter.
It should be noted that, a star-shaped transmission path is used for collecting data. Illustratively, referring to the embodiment shown in fig. 4, the first slave network node A, C, D, E sends signal instructions to the first master network node B, respectively. At this time, the first master network node B parses the signal command and waits for the signal command triggered by the next cycle or event.
It is understood that the first network node is located in a plurality of first channel groups, and the first channel groups are in one-to-one correspondence with the logic transmission paths.
It may be understood that step S100, acquiring a logic transmission path, includes: a path selection request is received from a user, the path selection request being for inputting a logical transmission path.
It should be noted that, the path selection request includes information of the logic transmission path, and the application of the first channel group can be more flexible by means of dynamic setting of the user. In other embodiments, the path selection request makes the determination of the logical transmission path in such a way that the first network node is triggered to read parameters of the loaded configuration.
It may be understood that the first network node is a slave network node, and processes the first service packet according to the response parameter, including:
forwarding the first service message and carrying out response processing on the first service message according to the response parameter.
It should be noted that, for each first slave network node, after receiving the first service message, the first service message is forwarded and then is responded, so that the residence time of the first service message in each first slave network node can be reduced, and the transmission efficiency of the first service message in the first channel group is further improved.
It is understood that the first network node is located in a first network domain, the method further comprising: and storing a first node identifier allocated by a second main network node from the first network domain, wherein the second main network node is obtained through self-election.
It should be noted that, referring to the embodiment shown in fig. 2, the first network domain Q1 includes A, B, C, D, E, F, G, H, and after the first network domain Q1 is successfully created, A, B, C, D, E, F, G, H mutually exchanges address relationship conversion tables stored in each of them, where the address relationship conversion tables are used to establish a mapping relationship between node identifiers and physical addresses. At this time, A, B, C, D, E, F, G, H knows the version information of each other node, taking a as an example, a obtains the latest address relation conversion table of H by comparing the version numbers of the address relation conversion tables of A, B, C, D, E, F, G, H, at this time, a determines H as the second master network node, and similarly, B, C, D, E, F, G, H confirms that H is the second master network node, at this time, the second master network node updates the routing table of A, B, C, D, E, F, G or performs the process of combining the newly added node and the network domain.
It can be understood that the node identifier allocated by the second main network node from the first network domain is saved, where the second main network node is obtained through self-election, and the method includes: storing the first node identifier into a routing table entry of a first network node with a first destination address in a first routing table; and acquiring a second node identifier corresponding to a second target address in the first routing table and storing the second node identifier in a corresponding routing table item.
It should be noted that, the first node identifier and the second node identifier are stored in the routing table entry, so that when the next hop address of the first service packet is queried, the physical address corresponding to the node identifier filled with the destination address in the first service packet is determined according to the address relationship conversion table, and then the routing table with the sequence number is compared according to the binary search in the routing table, in other embodiments, the routing table can be directly ordered according to the node identifier, thereby further improving the comparison efficiency.
It should be noted that, the creation of the first channel group and the first main network domain is not sequential.
It is noted that in some embodiments, the first network domain is automatically created. And stopping automatic updating of the route after routing addressing is carried out on the activated node, so that the first network domain is obtained. Illustratively, with reference to the embodiment shown in fig. 2, A, B, C, D, E, F, G, H is set to an active state and K is set to a deactivated state, at which time A, B, C, D, E, F, G, H may obtain a routing table having A, B, C, D, E, F, G as a destination address by routing broadcast. When the routing auto-update is stopped, the message generated by A, B, C, D, E, F, G can only be transmitted between A, B, C, D, E, F, G, thus automatically forming the first network domain. At this time, after the first network domain automatically elects through the second main network node, configuration information with the first network domain is generated, and initialization is performed through the second main network node in a neighbor flooding mode (that is, each initialized member node sends initialization information to uninitialized member nodes so as to realize initialization of the first network domain).
