The TTE network system mainly comprises a terminal processor node and a central switch, and an upper computer configures synchronous parameters and a time scheduling table of each node through a serial port or a network port. And after the system completes synchronization, each terminal processor completes data interaction of the service frame through the central switch according to the time scheduling table information.

Therefore, the link-level fault protection can be realized, and the service communication is not influenced by the fault of any physical link or switch.
However, when the terminal processor node fails, the application layer of the service end cannot operate normally.

The time-triggered ethernet network system mainly comprises a terminal system node and a central switch, wherein the terminal system node may be a Central Processing Unit (CPU) deployed in a board. And the upper computer configures synchronous parameters and a time scheduling table of the end system nodes and the switch through a serial port or a network port, and after each terminal system node completes synchronization, each end system node completes data interaction of a data service frame through the central switch according to time scheduling table information, wherein the time scheduling table is scheduled according to the number of virtual link numbers.
Referring to fig. 1 and fig. 2, for a network communication method provided in this embodiment of the present application, the method is applied to a target processor in a first board of a network communication system shown in fig. 1, where the first board is provided with a first processor and a second processor, the target processor is all processors in a working mode in the first board, and the network communication system further includes a first switch, where the first board is used for being in communication connection with a first service end;
as shown in fig. 2, the network communication method includes:
step S201, receiving a plurality of groups of communication data sent by the first switch according to a preset multicast forwarding scheduling table;
in a specific embodiment, the network communication system may be a time triggered ethernet network communication system, and data communication is performed between a communication service end and the communication service end through the time triggered ethernet network system, where the first service end is used as a receiver of data communication, the second service end is used as a sender of data communication, the network communication system further includes a sender board card 110, a receiver board card 130, and a central switch 120, the sender board card 110 includes a second board card and a fourth board card, the receiver board card 130 includes a first board card and a third board card, and the central switch 120 includes a first switch and a second switch.
The first service end is connected with the first board card, a plurality of processors are arranged in the first board card, wherein the processors in the same board card are the same processors, and each processor can be independently used as a terminal system in the time-triggered Ethernet network system and used for interacting with the first switch and the first service end.
In this embodiment, two identical processors are disposed in the first board card, and are the first processor and the second processor. The first processor and the second processor are both used for being in communication connection with a receiving end network port of the first switch, and when the first service end performs data interaction with the second service end, the target processor, namely the processor in the first board card in the working mode, receives multiple groups of communication data sent by the first switch according to a preset multicast forwarding scheduling table.
When the first processor and the second processor are both in the working mode, the first processor and the second processor can simultaneously serve as target processors to receive multiple groups of communication data sent by the first switch, and carry out the same processing process on the communication data.
When the first processor is in a failure mode, the first processor stops receiving the communication data, and the second processor still serves as a target processor to continue receiving the multiple groups of communication data sent by the first switch, and vice versa.
Step S202, according to the message serial number of each group of communication data, redundancy removing processing is carried out on all communication data to obtain a target communication data packet;
in a specific embodiment, each group of communication data received by the target processor has a packet sequence number, and the packet sequence number is a number for identification generated by the second service end for each group of data when sending data.
When the same message serial number exists between different groups of communication data in the multiple groups of communication data received by the target processor, redundancy removal processing is performed on the communication data, so that multiple groups of communication data with different message serial numbers are obtained, and a target communication data packet is formed corresponding to one group of communication data.
Specifically, the step of performing redundancy elimination processing on all communication data according to the packet sequence numbers of each group of communication data to obtain a target communication data packet includes:
comparing whether the message serial numbers of the communication data in each group of communication data are the same;
deriving a target communication data packet from the communication data with the same message serial number;
and respectively exporting the communication data with different message serial numbers to a corresponding target communication data packet.
In a specific embodiment, when the second service end sends the communication data through the sending board 110, the communication data sent by the second service end to the second board and the communication data sent by the fourth board may have the same condition and different conditions.
When the communication data sent by the second service end to the second board card and the communication data sent by the fourth board card are the same, the message serial numbers of the groups of communication data received by the target processor are the same, and then the target processor further performs redundancy removal processing on the communication data with the same message serial number.
When the communication data sent by the second service end to the second board card and the communication data sent by the fourth board card are different, and the message serial numbers of the groups of communication data received by the target processor are different, the target processor further processes the communication data with different message serial numbers respectively.
And after receiving each group of communication data forwarded by the first switch, the target processor performs redundancy removal processing on the communication data with the same message serial number to obtain a target communication data packet. And for the communication data with different message serial numbers, a target communication data packet is led out corresponding to one message serial number respectively.
Step S203, sending the target communication data packet to the first service end.
In a specific embodiment, the target processor sends all the derived target communication data packets to the first service end. After the first service end receives the target communication data packet sent by the target processor, if the same message serial number appears in the received multiple target communication data packets, redundancy removal processing is performed on the multiple target communication data packets with the same message serial number, and finally a communication data packet corresponding to one message serial number is obtained.
For example, when the first processor and the second processor are both in the working state, the first processor and the second processor simultaneously send the same target communication data packet to the first service end. And after receiving the target communication data packet sent by the first processor and the target communication data packet sent by the second processor, the first service end performs redundancy removal processing on the received target data packets with the same message sequence.
According to the network communication method provided by the embodiment, the plurality of processors are arranged in the first board card, and the backup work of the node part of the time-triggered Ethernet system is realized through the plurality of processors, so that the problem that data communication between communication service ends cannot be carried out when the processors of the board cards of the communication service ends are in failure is solved, and the communication reliability of the time-triggered Ethernet system is greatly improved.
Referring to fig. 3, a method flow diagram of a network communication method provided in an embodiment of the present application is applied to a first switch of a network communication system. As shown in fig. 1, the network communication system further includes a first board card and a second board card, the first board card is in communication connection with the transmitting-end network port of the first switch, the second board card is in communication connection with the receiving-end network port of the network communication system, the first board card includes a first processor and a second processor, and the second board card includes a third processor and a fourth processor. As shown in fig. 3, the method includes:
step S301, sequentially receiving each group of communication data sent by the third processor and the fourth processor;
step S302, synchronously and sequentially multicasting each group of the communication data to the first processor and the second processor according to a preset multicast forwarding schedule.
In a specific embodiment, the first switch receives, from a corresponding receiving-end network port, each set of communication data sent by the third processor and the fourth processor, where as shown in fig. 1, the third processor corresponds to a 1 st network port of the first switch, and the fourth processor corresponds to a 2 nd network port of the first switch.
The first switch multicasts each group of received communication data to the first processor and the second processor through corresponding sending end network ports, wherein the first processor corresponds to the 5 th network port of the first switch, and the second processor corresponds to the 6 th network port of the first switch.
The preset multicast forwarding schedule may be a multicast forwarding schedule set in advance, and in this embodiment, the multicast forwarding schedule may be as shown in table 1, where a source end is a terminal system node of a sender, and a target end is a terminal system node of a receiver:
table 1 multicast forwarding schedule
According to a specific implementation manner of the embodiment of the present application, the step of synchronously multicasting each group of the communication data to the first processor and the second processor in sequence according to a preset multicast forwarding schedule includes:
generating a multicast forwarding scheduling table corresponding to each group of communication data according to the receiving sequence, wherein the sequence of the sending time of each group of communication data in the multicast forwarding scheduling table is consistent with the receiving sequence;
and synchronously multicasting each group of communication data to the first processor and the second processor at each sending time in sequence according to the multicast forwarding scheduling table.
In a specific embodiment, as shown in table 1, the first switch receives the communication data sent by the third processor first, and then receives the communication data sent by the fourth processor. Then at a first time T1, the communication data sent by the third processor is forwarded to the first processor and the second processor through the preset virtual link number synchronization. And at a second time T2, forwarding the communication data sent by the fourth processor to the first processor and the second processor synchronously through a preset virtual link number.
In addition, if the first switch receives the communication data transmitted by the fourth processor first and then receives the communication data transmitted by the third processor, the switch may also adjust the multicast forwarding schedule in real time, multicast the communication data transmitted by the fourth processor through the virtual link 2 at a first time, and multicast the communication data transmitted by the third processor through the virtual link 1 at a second time.
Different from the traditional unicast virtual link design, the method can reduce the number of virtual links in the time-triggered Ethernet network system in a multicast forwarding mode, thereby accelerating the data transmission speed and improving the communication reliability of the time-triggered Ethernet network system.
Referring to fig. 1, a network communication system provided for the embodiment of the present application includes: the system comprises a first service end, a second service end, a first board card, a second board card and a first switch, wherein the first board card comprises a first processor and a second processor, and the second board card comprises a third processor and a fourth processor;

the first processor and the second processor are respectively in communication connection with the first service end and used for sending a target communication data packet to the first service end.
In a specific embodiment, the specific implementation process of the network communication system may refer to the specific implementation processes of the target processor and the first switch in the first board, and details are not repeated here.
According to a specific implementation manner of the embodiment of the present application, the system further includes a second switch;
the third processor and the fourth processor are respectively in communication connection with a receiving end network port of the second switch and used for sending communication data to the second switch;
the first processor and the second processor are respectively in communication connection with a network port of a sending end of the second switch and are used for receiving multiple groups of communication data sent by the second switch according to a preset multicast forwarding scheduling table;
when the first switches are in a normal mode, the first switches synchronously multicast the communication data of each group to the first processor and the second processor according to a preset multicast forwarding scheduling table, and the second switches are in a standby state;
and when the first switch is in a failure mode, the second switch synchronously multicasts each group of communication data to the first processor and the second processor according to a preset multicast forwarding scheduling table.
In a specific embodiment, the system further includes a second switch, where the second switch is a backup switch of the first switch, and connection relationships and interaction manners between the second switch and the first processor, the second processor, the third processor, and the fourth processor may refer to connection relationships and interaction manners between the first switch and each processor.
Specifically, when the first switch is in a normal operating mode, the second switch may be in a standby state, that is, the data communication between the first service end and the second service end is only performed through the first switch in a multicast forwarding step, and the second switch receives the communication data sent by the third processor and the fourth processor, but does not perform the multicast forwarding step.
When the first switch cannot realize multicast forwarding or when the first switch makes data have errors in the process of receiving the data, determining that the first switch is in a failure mode. And when the first switch is in a failure mode, the second switch starts to work as a backup switch, and performs multicast forwarding on the received communication data of the third processor and the fourth switch according to a preset multicast forwarding scheduling table.
In an embodiment, the first switch and the second switch may be in an operating mode at the same time, that is, both the first switch and the second switch forward the communication data received from the receiving port according to a preset multicast forwarding schedule.
When the first switch and the second switch are simultaneously in a working mode, the target processor receives the same communication data from the transmitting end network port of the first switch and the transmitting end network port of the second switch at the same time, and the target processor screens the same communication data received from the first switch and the second switch at the same time into one communication data according to a preset redundancy removing algorithm.
According to a specific implementation manner of the embodiment of the application, the system further includes a third board card and a fourth board card, the third board card includes a fifth processor and a sixth processor, and the fourth board card includes a seventh processor and an eighth processor;
the seventh processor and the eighth processor are respectively in communication connection with the second service end, and are configured to receive communication data sent by the second service end;
the seventh processor and the eighth processor are respectively in communication connection with a receiving end network port of the first switch and used for sending communication data to the first switch;
the fifth processor and the sixth processor are respectively in communication connection with a network port of the sending end of the first switch and are used for receiving multiple groups of communication data sent by the first switch according to a preset multicast forwarding scheduling table;
the fifth processor and the sixth processor are respectively in communication connection with the first service end, and are configured to send a target communication data packet to the first service end.
In a specific embodiment, the network communication system may further include a third board card and a fourth board card, where the third board card is a backup board card of the first board card, and the fourth board card is a backup board card of the second board card.
Specifically, the third board card includes a fifth processor and a sixth processor, the fourth board card includes a seventh processor and an eighth processor, in the network communication system, the first processor, the second processor, the fifth processor, and the sixth processor all serve as terminal system nodes of a receiving party, and the third processor, the fourth processor, the seventh processor, and the eighth processor all serve as terminal system nodes of a sending party.
As shown in fig. 1, the third processor corresponds to the 1 st port of the first switch, the fourth processor corresponds to the 2 nd port of the first switch, the seventh processor corresponds to the 3 rd port of the first switch, the eighth processor corresponds to the 4 th port of the first switch, the first processor corresponds to the 5 th port of the first switch, the second processor corresponds to the 6 th port of the first switch, the fifth processor corresponds to the 7 th port of the first switch, and the sixth processor corresponds to the 8 th port of the first switch.
When the network communication system includes the first board, the second board, the third board, and the fourth board, the multicast forwarding schedule preset by the first switch may be a multicast forwarding schedule as shown in table 2:
table 2 multicast forwarding schedule
As shown in table 2, when the first switch receives the sets of communication data in the order of the third processor, the fourth processor, the seventh processor, and the eighth processor, the first switch synchronously forwards the communication data of the third processor to the first processor, the second processor, the fifth processor, and the sixth processor at a first time T1. And synchronously forwarding the communication data of the fourth processor to the first processor, the second processor, the fifth processor and the sixth processor at a second time T2. At a third time T3, the first processor, the second processor, the fifth processor and the sixth processor forward the communication data of the seventh processor. At a fourth time T4, the first processor, the second processor, the fifth processor, and the sixth processor forward the communication data of the eighth processor.
When the first switch receives each group of communication data according to other sequences, the multicast forwarding schedule changes in real time according to the sequence in which the first switch receives the data, which may refer to the implementation process in the above embodiment specifically, and is not described here again.
When a sending end of the time-triggered ethernet network system has four end system nodes, and a receiving end also has four end system nodes, if a unicast virtual link design is adopted, there are 4 × 4 — 16 virtual links, and forwarding needs to be performed at 16 different times, which makes data communication between the first service end and the second service end complicated and more time-consuming.
In addition, by setting a plurality of processors in the board card as the nodes of the terminal system, the problem that when the processors in the board card are in failure, data communication between the service ends cannot be carried out is avoided, and the reliability of the time-triggered Ethernet network system is greatly improved.
