It should be understood that the embodiments of the present application are not so limited in scope. The embodiments of the application include many variations, modifications and equivalents within the spirit and scope of the appended claims.
Features that are described and/or illustrated with respect to one embodiment may be used in the same way or in a similar way in one or more other embodiments, in combination with or instead of the features of the other embodiments.
It should be emphasized that the term "comprises/comprising" when used herein, is taken to specify the presence of stated features, integers, steps or components but does not preclude the presence or addition of one or more other features, integers, steps or components.
Referring to fig. 1, a method for isolating communication packet transmission provided by the present application specifically includes:
s101, acquiring communication links among nodes in a communication system, constructing a plurality of communication channels among adjacent nodes according to the communication links, and identifying channel priority of each communication channel;
s102, extracting the message type and the target node of the received message to be transmitted, and obtaining the corresponding message priority according to the message type;
s103, acquiring a communication path between a current node and a target node according to the target node, and acquiring a plurality of transmission channels between associated nodes and channel priorities of the transmission channels according to the communication path;
s104, matching the message priority with the channel priority to obtain a corresponding transmission path, and transmitting the message to be transmitted according to the transmission path.
Step S101 may be implemented by using an existing channel construction method in actual work, for example, it is determined that a communication system includes A, B, C, D four nodes, and a communication link between the nodes is a and B, C, and B, C is connected to D, then a plurality of communication channels are respectively constructed between AB, AC, BD, and CD, for example, Tab1, Tab2, and Tab3 … … Tabn may be constructed between AB, and the channel priorities corresponding to the communication channels are 1, 2, and 3 … … n; with 1 as the highest priority, the message is transmitted from Tab3 when the message is transmitted with priority 3; as for the message priority, the following method can be used for defining: the lowest level of the monitoring message is 5, the level of the automatic operation execution message is 4, the level of the software deployment message is 3, the level of the configuration comparison message is 2, and the level of the emergency switching message is 1; of course, in actual work, a corresponding priority setting scheme can be selected according to actual needs, and the application is not limited herein; therefore, different communication channels transmit transmission messages with different priorities, so that communication message isolation is realized, and the situations of high-priority message waiting and the like caused by message mixing are solved.
In an embodiment of the present application, the method may further include: each node detects the communication state of a transmission channel between the current node and the adjacent node through a detection message according to a preset period; when any transmission channel is abnormal in communication, the abnormal information of the transmission channel is provided to the adjacent node. Specifically, in actual application, in order to avoid the situation that a message cannot be effectively transmitted due to a communication channel failure, each node further identifies the transmission state of each communication channel according to a preset period by using a communication state identification method such as a detection message and notifies each node, so that each node can timely adjust a message transmission strategy.
Referring to fig. 2A, in an embodiment of the present application, matching the priority of the packet with the priority of the channel to obtain a corresponding transmission path further includes:
s201, detecting the communication state of one or more transmission channels contained in the transmission path;
s202, when any one transmission channel in the transmission path is abnormal in communication, the communication states and corresponding channel priorities of other transmission channels between the current node and the target node are obtained;
s203, the transmission path is adjusted through a preset strategy according to the communication state and the channel priority of each transmission channel.
In the above embodiment, obtaining the corresponding transmission path through the preset policy filtering according to the communication state and the channel priority of each transmission channel may include: and comparing the message priority with the channel priority of each transmission channel, and replacing the transmission channel with abnormal communication in the transmission path by the transmission channel with the highest channel priority when one or more channel priorities are lower than the message priority. Or comparing the message priority with the channel priority of each transmission channel, and replacing the transmission channel with the lowest channel priority for the transmission channel with abnormal communication in the transmission path when the channel priorities are higher than the message priority. Specifically, in actual operation, when a Tn channel fails in a transmission path, a channel with a normal state that uses Tmax (m, m > n) is preferentially used for transmission, that is, the smallest m of all m with a priority number greater than n is selected; if the channel does not exist, the channel with Tmin (m, m < n) is used for transmitting, namely, all Tm with the priority lower than Tn are selected, and the priority is the highest; where T0 has the highest priority, the larger the number, the lower the priority. For example, the determined transmission paths of the message to be transmitted, which is transmitted from the node a to the node D and has the priority of 3, are Tab3 and Tbd3, where Tab3 and Tbd3 are both channels having the priority of 3, and at this time, when Tab3 fails and a transmission channel, Tab4, exists between a and B, then Tab4 may be selected as the transmission channel to transmit, and if only 3 channels are established between a and B: tab1, Tab2 and Tab3, in which case Tab2 can be selected as the transmission channel for transmission.
In view of the fact that in actual work, the communication state is not fixed, and the condition that all transmission channels corresponding to the channel priorities of a certain node are abnormal exists; at this time, in an embodiment of the present application, the method may further include: and when all transmission channels with the channel priority equal to or lower than the message priority in the transmission path are abnormal, the messages to be transmitted are sent to a plurality of transmission paths between the current node and the target node in the transmission path in a balanced manner. Specifically, when node a is connected to node B, C and node B, C is connected to node D, path ABD and path ACD are different paths, and the path selection policy of a is actually selected according to the priority of the path; the channel selection mode of the packet sent by the node a to the node D may be as follows: for convenience of description, please refer to fig. 2B, assuming that the priority is only 1-3 at present, 3 channels are configured between AB, AC, BD, and CD, which may be named Tab1, Tab2, and Tab3, similarly to the foregoing, Tab1 has a priority 1 greater than Tab2, Tab2 has a priority 2 greater than Tab3, and so on; when the channel is normal, the message A sent to the message D is sent through the corresponding channels B and C in a balanced manner; when the Tbd2 is abnormal, the node B will notify the node a of the abnormal information, and because the Tbd3 is still normal, the transmission policy for the node a will not change, at this time, because the message with the priority level 2 is transmitted to the node B, the transmission of the message with the priority level 1 will not be affected, and only the message with the priority level 3 will be affected, so the transmission policy for the node a will not change; when the Tbd3 is abnormal, the node a sends all the messages with the priority of 3 through the Tac3, and at this time, the node B will not receive the 3-level messages from the node a, even though the Tab3 is still normal (communication is maintained, the detection messages can be sent and received), if the messages with the priority of 3 are sent to the node B, the messages with the priority of 2 will be affected, so the node a will not continue to send the 3-level messages to the node B through the Tab3, but send the 3-level messages to the node B; when Tbd2 and Tbd3 are abnormal at the same time, node a will send all messages with priority 2 and 3 through Tac2 and Tac3, at this time node B will not receive messages with priority 2 and 3 from node a, even if Tab2 and Tab3 are still normal, if continue to send, messages with priority 1 will be affected; at this time, if the Tcd2 or Tcd3 is also abnormal, the node a still maintains the policy, only one of the two channels Tcd2 and Tcd3 is abnormal, that is, the messages with the priority levels of 2 and 3 are sent to the message with the priority level of 1, which is not affected by the sending of the message with the priority level of 2 and 3, so the policy a maintains that the messages with the priority levels of 2 and 3 are all sent through Tac2 and Tac3, but when the abnormality occurs simultaneously in Tcd2 and Tcd3, the node a changes to send all the messages to the node B and the node C in a balanced manner, at this time, only the path with the priority level of 1 from a to D is still clear, and no path with other priority levels exists, so the messages of each level are sent in a balanced manner. That is, no matter how many paths exist from the current node to the target node when the packet is forwarded, the policy does not affect the high-priority channel as much as possible, preferentially uses the channel with the relatively low priority as much as possible, and ensures the real-time performance of the high-priority channel.
Referring to fig. 3, the present application further provides a communication packet transmission isolation apparatus, which includes a construction module, an analysis module, a matching module, and a sending module; the construction module is used for acquiring communication links among nodes in a communication system, constructing a plurality of communication channels among adjacent nodes according to the communication links and identifying the priority of the channels for each communication channel; the analysis module is used for extracting the message type and the target node of the received message to be transmitted and obtaining the corresponding message priority according to the message type; the matching module is used for acquiring a communication path between the current node and the target node according to the target node and acquiring a plurality of transmission channels between the associated nodes and channel priorities of the transmission channels according to the communication path; the sending module is used for matching the message priority with the channel priority to obtain a corresponding transmission path, and transmitting the message to be transmitted according to the transmission path.
Referring to fig. 4, in the above embodiment, the apparatus may further include a detection module and a balancing module, where the detection module is disposed at each node and is configured to detect, according to a preset period, a communication state of a transmission channel between a current node and an adjacent node through a detection packet; when any transmission channel is abnormal in communication, the abnormal information of the transmission channel is provided to the adjacent node. The balancing module is connected with the detection module and is used for sending the messages to be transmitted to a plurality of transmission paths between the current node and the target node in the transmission paths in a balanced manner through the sending module when all the transmission paths with the channel priorities equal to or lower than the message priorities in the transmission paths are abnormal. Further, in an embodiment of the present application, the sending module further includes an adjusting unit, where the adjusting unit is configured to detect a communication state of one or more transmission channels included in the transmission path; when any one transmission channel in the transmission path is abnormal in communication, the communication states and the corresponding channel priorities of other transmission channels between the current node and the target node are obtained; and adjusting the transmission path through a preset strategy according to the communication state and the channel priority of each transmission channel.
