Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The embodiment provides a method for transmitting a time-sensitive message in an HSR network, which can be used for transmitting a time-sensitive message in an HSR ring network, and in the HSR ring network communication environment, a local device message and an HSR ring network message received in the communication environment are transmitted. As shown in fig. 1, includes:
s11, when the received message is a time sensitive message, determining the source of the time sensitive message.
For example, when a dual connectivity switching node DANH receives an uploaded to-be-transmitted message, source identification is performed on the received to-be-transmitted message, where the to-be-transmitted message may be obtained from a local device, a left ring of an HSR ring network, or a right ring of the HSR ring network. The source of the to-be-transmitted message may be obtained according to the message tag, for example, if the tag of the to-be-transmitted message is "a", which indicates that the time-sensitive message is from the HSR ring network, when the tag of the received to-be-transmitted time-sensitive message is "a", it is determined that the to-be-transmitted time-sensitive message is from the HSR ring network, and the time-sensitive message whose tag is not "a" is from the local device. The method for distinguishing the message sources in the embodiment of the application is not limited, and a person skilled in the art can determine the method according to actual needs.
And S12, when the time-sensitive message is uploaded from the local equipment, packaging the time-sensitive message and storing the time-sensitive message in the first local queue.
For example, the time-sensitive packet uploaded by the local device may be encapsulated into a packet format suitable for transmission in the current HSR ring network according to the packet transmission format of the current network channel, and stored in the first local queue.
S13, when the time sensitive message is input from the ring network, it is determined whether the current network channel is occupied by the time sensitive message.
Illustratively, when a time-sensitive message input by the HSR ring network is received, whether a time-sensitive message being transmitted exists in a current network channel is detected, and whether the transmitted message is the time-sensitive message can be determined by identifying a packet header of the message transmitted in the current network channel. For example, if the header identifier of the packet to be transmitted is "B" and is characterized as a time-sensitive packet, when the packet header identifier of the packet transmitted in the current network channel is identified as "B", it is determined that the packet currently being transmitted is a time-sensitive packet, that is, the current network channel is occupied by the time-sensitive packet, and when the packet header identifier of the packet transmitted in the current network channel is identified as not "B", it is determined that the packet currently being transmitted is a non-time-sensitive packet, that is, the current network channel is occupied by the non-time-sensitive packet.
And S14, if the current network channel is occupied by the time-sensitive message, storing the time-sensitive message into a first forwarding queue.
Illustratively, when it is detected that there is a time-sensitive message being transmitted in the current network channel, the time-sensitive message input through the HSR ring network is already in a message format transmitted in the encapsulated HSR ring network, and since the time-sensitive message is a message that needs to be transmitted in real time and cannot be interrupted, the time-sensitive message input through the HSR ring network can be transmitted only after the time-sensitive message being transmitted in the current network channel is transmitted, and can be stored in the first forwarding queue.
And S15, if the current network channel is not occupied by the time-sensitive message, transmitting the time-sensitive message stored in the first local queue or the first forwarding queue according to a preset first message transmission strategy.
Illustratively, the first messaging policy may include a forwarding first, local first, weighted, time sliced, first come first send, prioritized, etc. control policy. The category of the first message transmission policy is not limited in the present application, and those skilled in the art can determine the category according to actual needs. Taking the first message transmission strategy as a local priority example for explanation, if both the first forwarding queue and the first local queue contain time-sensitive messages to be transmitted, the time-sensitive messages in the first local queue are preferentially transmitted based on a local priority control strategy. The time-sensitive message represents a message needing real-time transmission, the transmission priority of the non-time-sensitive message is lower than that of the time-sensitive message, if the message being transmitted in the current network channel is the non-time-sensitive message, the time-sensitive message occupies the network channel of the non-time-sensitive message for preferential transmission, the real-time performance of time-sensitive message transmission is guaranteed, and the waiting time delay of the time-sensitive message is reduced.
In the time-sensitive message transmission method provided by this embodiment, a source of a time-sensitive message is determined, the time-sensitive message uploaded by a local device is packaged and stored in a corresponding first local queue, when the time-sensitive message input in a ring network is received, it is determined whether a current network channel is occupied by the time-sensitive message, if the current network channel is occupied by the time-sensitive message, the received time-sensitive message is stored in a first forwarding queue, and when the network channel is not occupied by the time-sensitive message, the time-sensitive message is transmitted according to a preset first message transmission policy, so that priority transmission of the time-sensitive message is ensured, waiting time delay of the time-sensitive message is reduced, transmission efficiency of the time-sensitive message is improved, and real-time performance of time-sensitive message transmission is ensured.
As an optional embodiment of the present application, before step S11, the method further includes:
firstly, the received message is classified.
For example, the type of the packet may be obtained by analyzing a header of the received packet, where the header of the packet includes an identifier that characterizes a type of the packet, and the received packet may be determined to be a time-sensitive packet or a non-time-sensitive packet by identifying the header identifier of the packet. For example, if the header identifier of the received packet is "C", which means that the received packet is a time-sensitive packet, when the header identifier of the received packet is "C", the received packet is determined to be a time-sensitive packet, and when the header identifier of the received packet is not "C", the received packet is determined to be a non-time-sensitive packet.
Secondly, determining the message types according to the classification result, wherein the message types comprise time-sensitive messages and non-time-sensitive messages.
For example, the specific description of the message type refers to the related description of the above embodiment, and is not repeated here.
As an optional embodiment of the present application, the method further comprises:
firstly, when a time sensitive message is input from a ring network, whether a current network channel is occupied by a non-time sensitive message is determined.
For example, for a specific description on whether the current network channel is occupied by the non-time-sensitive packet, refer to the related description of the foregoing embodiment, and details are not described here again.
Secondly, if the current network channel is occupied by the non-time-sensitive message, the transmission of the non-time-sensitive message is interrupted, and the time-sensitive message is transmitted.
For example, if the message transmitted in the current network channel is a non-time-sensitive message, the time-sensitive message to be transmitted occupies the network channel to perform message transmission, and at the same time, the transmission of the non-time-sensitive message being transmitted in the network channel is interrupted. By interrupting the transmission of the non-time-sensitive message, the network channel resources are released to transmit the time-sensitive message, and the real-time property of the time-sensitive message transmission is ensured.
As an optional implementation manner of the present application, the time-sensitive packet transmission method further includes:
first, when the received message is a non-time-sensitive message, the source of the non-time-sensitive message is determined.
For example, the method for determining the source of the non-time-sensitive packet and the method for determining the source of the time-sensitive packet have the same principle, that is, the source can be determined by the tag of the packet.
Secondly, when the non-time-sensitive message is uploaded from the local equipment, the non-time-sensitive message is subjected to message splitting processing to obtain a plurality of corresponding short messages, and the plurality of short messages are packaged and stored in a second local queue.
Illustratively, when a non-time-sensitive message uploaded by the local device is received, the non-time-sensitive message may be split into multiple short frames of messages, and the multiple short frames of messages are encapsulated according to a message format transmitted by a network channel of the current HSR ring network and stored in the second local queue. The splitting of the multi-frame short message can be carried out according to the average splitting of the total length of the non-time sensitive message to obtain a plurality of short messages in an HSR message format; the method and the device can also split the data carried by the non-time-sensitive message according to the segments to obtain a plurality of short messages in the HSR message format.
And thirdly, when the non-time-sensitive message is input from the ring network, the non-time-sensitive message is stored in a second forwarding queue.
Illustratively, when a non-time-sensitive message input by the HSR ring network is received, the non-time-sensitive message already in the HSR ring network is a split and encapsulated short message, and the received short message belonging to the non-time-sensitive message can be stored in the second forwarding queue without splitting and encapsulating again.
And thirdly, when the network channel is idle, transmitting the short message stored in a second local queue or a second forwarding queue according to a preset second message transmission strategy.
Illustratively, the second messaging policy may include a forwarding first, local first, weighted, time sliced, first come first sent, prioritized, etc. control policy. The type of the message transmission strategy is not limited in the application, and can be determined by a person skilled in the art according to actual needs. When the network channel is idle, that is, there is no any message being transmitted in the current network channel, if both the second forwarding queue and the second local queue contain short messages to be transmitted, the second message transmission policy is taken as the local queue priority for illustration, and based on the control policy of the local queue priority, the short messages in the second local queue are preferentially transmitted. By setting a transmission strategy for the transmission of the short messages in the second local queue and the second forwarding queue, the short messages in the second local queue and the second forwarding queue are prevented from being transmitted simultaneously, network channels are mutually occupied, and the transmission efficiency of the short messages is ensured.
As an optional implementation manner of the present application, when a network channel is idle, according to a preset second packet transmission policy, transmitting a short packet stored in a second local queue or a second forwarding queue, includes:
firstly, when the short message does not meet the integrity requirement, discarding the short message.
Illustratively, before transmitting the short message in the second local queue or the second forwarding queue, it is necessary to determine whether the short message to be transmitted is a complete short message, and the short message may be identified by a message format of the short message, and when the short message satisfies an HSR message encapsulation format, it may be determined that the short message satisfies an integrity requirement. If the message format of the short message is identified, and the message encapsulation format of the short message is found not to meet the integrity requirement, the short message can be determined to be the interrupted transmission message, and the short message is discarded, so that the interrupted incomplete short message is prevented from continuously occupying a transmission channel, and the waste of transmission bandwidth is avoided.
And secondly, when the short message meets the integrity requirement, transmitting the short message.
Illustratively, if the short message to be transmitted is complete and no message is sent in the current network channel, the short message may be transmitted. When the short message is transmitted, a non-time-sensitive message sending storage area can be established, a frame of short message waiting to be sent is extracted from a second local queue or a second forwarding queue to the non-time-sensitive message sending storage area according to a second message transmission strategy, when a network channel is idle, the short message of the non-time-sensitive message sending storage area is transmitted, but the short message transmission can be interrupted by a newly arrived time-sensitive message until the non-time-sensitive message sending storage area is emptied after the short message is successfully sent. After the non-time-sensitive message sending storage area is emptied, a frame of non-time-sensitive short messages of a second forwarding queue or a second local queue can be extracted according to a second message transmission strategy, stored in the non-time-sensitive message sending storage area and sent when a channel is idle next time, and a non-time-sensitive message sending storage area is established, so that a backup retransmission mechanism of the non-time-sensitive messages can be realized.
The embodiment provides a time-sensitive message transmission method in an HSR network, which can be used for any local device in an HSR ring network communication environment. As shown in fig. 2, includes:
and S21, receiving the message.
Illustratively, the message may be a time-sensitive message or a non-time-sensitive message sent by a dual-connectivity switching node in an HSR ring network communication environment.
And S22, when the received message is a time-sensitive message, decapsulating the time-sensitive message to obtain message information.
For example, the type of the received packet is determined, and for a specific description of determining the type of the packet, reference is made to the description of the corresponding part of the above embodiment. If the received message is a time-sensitive message, removing the HSR header of the message, and analyzing the message to obtain the information of the time-sensitive message. Taking the HSR ring network left ring network message as an example, when receiving the time-sensitive message sent by the HSR ring network left ring network, the HSR header of the time-sensitive message is removed, and the message content is analyzed to obtain the time-sensitive message information.
S23, when the received messages are a plurality of short messages used for transmitting non-time-sensitive messages, the short messages are de-encapsulated, and all the short messages obtained after de-encapsulation are combined to obtain message information.
Illustratively, if the received message is a frame of short message belonging to a non-time-sensitive message, removing the HSR header of the short message, analyzing the short message to obtain message information of the short message, storing the message information of the short message, and after other short messages belonging to the same non-time-sensitive message arrive and are decapsulated successfully, combining all the received short messages belonging to the same non-time-sensitive message to obtain a complete non-time-sensitive message, thereby obtaining message information transmitted by the non-time-sensitive message.
In the method for transmitting a time-sensitive message in an HSR network provided in this embodiment, time-sensitive message information is obtained by decapsulating a received message, decapsulating a plurality of received short messages belonging to the same non-time-sensitive message, and merging all the short messages obtained after decapsulation to obtain completed non-time-sensitive message information, so that the accuracy of the received time-sensitive message information and the non-time-sensitive message information is ensured.
