The specification may use the word "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the application.

The network data processing method of the embodiment of the application is applied to a network, wherein the network can be a local area network, such as an Ethernet formed by various devices in a vehicle or other small local area networks, and the processing method can be used for network architecture and data transmission of network link redundancy configuration applicable to vehicle-mounted or other small local area network topologies.

In the network of this embodiment, a plurality of different components are provided, where the components are sequentially connected to the network, and each component corresponds to a respective network device, and the network device sends and receives data through the respective corresponding component. In one embodiment, the component may be an other corresponding device independent of the network device, and in another embodiment, the component may also be part of the network device, or a slave device, for providing support for network data interactions for the network device.

Each component is provided with a first interface and a second interface of different types, and the first interface and the second interface have compatible network communication protocols. For example, the first interface and the second interface can both perform network communication based on the IEEE 802.1CB protocol of the IEEE TSN protocol family. In one embodiment, the first interface may be a G-port, and the second interface may be a T-port, with each component being connected to its corresponding network device through the first interface and to other components in the network through the second interface.

Based on the network architecture, the network data processing method of the application comprises the steps of analyzing the content in the data packet when the first interface of the first component in the network receives the data packet sent by the first network device corresponding to the first component, and determining whether the data packet needs to be duplicated or not. If it is determined that the data packet needs to be copied, the first component can copy the data packet into a plurality of data packets with the same data content, and the data packets are respectively sent to the second interfaces of the second component through the second interfaces of the first component by different network transmission paths, so that the data packet can be ensured to be sent to the target component. And the second component can select a specific mode for sending and transmitting the data packet according to the playing type of the data packet. This includes a first interface that communicates the data packet to a second component, which may be a target component. The data packet may also be sent to the second interface of the other component in the network and forwarded to the second interface of the target component, which may be one or more, through the second interface of the other component. The target component then transmits the data packet to the corresponding target network device through the first interface. Thereby, the reliability of transmitting the data packet is effectively improved while the accurate target network equipment is determined.

The network data processing method of the present application will be described in detail with reference to specific embodiments, and fig. 1 is a flowchart of the network data processing method of the embodiment of the present application, as shown in fig. 1 and with reference to fig. 2 and 3, and the method includes the following steps:

s100, determining whether the data packet needs to be copied or not based on a first field in a frame structure of the data packet when a first interface of a first component receives the data packet sent by first network equipment, wherein the first component corresponds to the first network equipment.

The network data processing method of the application is applied to a network, and the network can be a local area network, such as an Ethernet formed by various devices in a vehicle or other small local area networks. The network is provided with a plurality of components, each corresponding to a respective network device. If the first component corresponds to a first network device, the second component corresponds to a second network device.

And each component is provided with a first interface (such as a G port) and a second interface (such as a T port) of different types, so that the functions of data transmission processing are distinguished based on the interfaces of different types, and the data packet delivery efficiency is improved. The first component receives a data packet sent by the first network device through the first interface of the first component, analyzes the content of the data packet, and determines whether the data packet needs to be copied or not based on the first field. The data packet has a corresponding frame structure including multiple information therein. In one embodiment, the first interface may be a G-port and the second interface may be a T-port.

For example, as shown in fig. 2, the frame structure of the ethernet based on the 802.3 protocol includes a plurality of fields, wherein an org code field has 3 bytes, a first byte in the org code field is an FT field, and the last two bytes in the org code field are FID fields, which may represent a unique ID of a packet in the ethernet. In this embodiment, the FT field is determined as a first field, where the first field may be used to characterize whether the data packet needs to be copied. The FID field is determined as a second field, which may represent identity information of the data packet.

And S200, if the data packet needs to be copied, performing copy operation on the data packet to generate a plurality of identical data packets.

Illustratively, whether the data packet needs to be copied is determined based on the contents of the first field, e.g., a "1" for the first field indicates that the data packet needs to be copied and a "0" for the first field indicates that the data packet does not need to be copied.

If it is determined that the data packet needs to be copied based on the first field, the first component may perform a copy operation on the data packet to generate a plurality of data packets having the same content. And respectively processing the plurality of data packets generated after copying through the network.

And S300, respectively transmitting the data packets to the second interfaces of the second components through the second interfaces of the first components by using different network transmission paths.

Illustratively, the first component has a plurality of second interfaces, each of which may transmit data packets relatively independently. In this embodiment, the plurality of data packets may be sent to the second interfaces of the second component through the plurality of second interfaces of the first component through different network transmission paths. Wherein one second interface comprising the first component sends one data packet to the second interface of the second component in a first transmission direction and the other second interface of the first component sends the other data packet to the second interface of the second component in a second transmission direction. Therefore, the data packet can be transmitted to the second component, and the reliability of data transmission is improved.

In one embodiment, the second interface of the first component sends the plurality of data packets to the second interface of the second component respectively through different network transmission paths, and the second interface of the second component receiving the data packets may be a different second interface. Therefore, the plurality of second interfaces can cooperate with each other to respectively receive the data packets, and the receiving efficiency is improved.

And S400, transmitting the data packet to a first interface of the second component and/or transmitting the data packet to a second interface of other components in the network according to the play type of the data packet and a network address in a frame structure of the data packet so as to transmit the data packet to target network equipment corresponding to the target component.

The play-out type of the data packet includes, by way of example, at least one of unicast, multicast and broadcast. The transmission modes and/or the transmission target network devices of the data packets corresponding to different play types are different. In one embodiment, unicast means that the first component propagates the data packet unidirectionally to a single destination component, multicast means that the first component propagates the data packet to multiple destination components, and broadcast means that the first component propagates the data packet to all components in the network, i.e., all components are destination components.

The frame structure of the data packet has a network address, such as a MAC address part of the frame structure, which includes information such as a destination address, a source address, and the like of the data packet. The network address contains information such as the source and destination of the data packet. Therefore, the application can accurately transmit the data packet to the second component and/or other components according to the play type of the data packet and the network address in the frame structure of the data packet. For example, the data packet is transmitted to a second component, which is the target component. Or the data packet is transmitted to other components (such as a third component, a fourth component and the like) through the second component, and then forwarded to the target component by the other components.

When the second component is the target component, the first component transmits the data packet to the second interface of the second component, the second component transmits the data packet to the first interface of the second component, the first interface of the second component is connected with the first interface of the target network device, the data packet is transmitted to the first interface of the target network device through the first interface of the second component, and then the data packet is transmitted to the target network device.

The specific transmission mode further comprises a second interface, wherein the first interface transmits the data packet to other components in the network, and the other components can be non-target components or target components. The first component may directly forward the data packet to the target component, or may forward the data packet to the target component step by step via one or more other components, where the target component then sends the data packet to the target network device corresponding to the data packet.

In one embodiment of the present application, after the data packet is sent to the second interface of the second component, as shown in fig. 4, the method further includes the steps of:

S500, determining whether other data packets which are the same as the data packet which is currently received are received by a second interface of the second component or not based on a second field in the frame structure of the data packet and/or a network address in the frame structure of the data packet, wherein the second field is used for identifying the identity of the data packet.

Illustratively, the frame structure includes a plurality of fields, wherein the org code field has 3 bytes, the latter two of which are FID fields, which may represent a unique ID of the data packet in the Ethernet. The FID field is determined as the second field in this embodiment. The second field may represent identity information of the data packet.

The network address in the frame structure of the data packet may be a MAC address portion of the frame structure that includes information such as a destination address, a source address, etc. of the data packet. After receiving the data packet sent by the first component, the second component may record part of the content of the network address in the data packet, i.e. record the received data packet. In one embodiment, the received data packet may be recorded based on the FID field (second field) corresponding to the original MAC address in the network address. When the second component receives the same data packet again, for example, a second interface of the second component has received a data packet. The other second interface of the following second component receives the same data packet as well. The second component may determine whether the same data packet has been received before based on the second field and/or the network address of the data packet.

And S600, if the data packet is determined to have been received, discarding the data packet which is currently received.

For example, if it is determined that the second component has received a data packet, the second component will not receive the same data packet any more to conserve system resources. The second component discards the currently received data packet, thereby saving system processing resources and saving storage space.

In one embodiment of the present application, the determining whether other data packets identical to the currently received data packet have been received by the second interface of the second component based on the second field in the frame structure of the data packet and/or the network address in the frame structure of the data packet, as shown in fig. 5, includes:

S510, determining the identity information of the data packet based on a second field in the frame structure of the data packet and the network address of the data packet;

s520, comparing the identity information of the data packet with a record table stored by the second component;

and S530, in the case that the identity information of the data packet is recorded in the record table, determining that the other data packet which is the same as the currently received data packet is received by the second interface of the second component.

Illustratively, in combination with the above embodiment, the second field in the frame structure of the data packet may be an FID field as described above, and the FID field may represent a unique ID of the data packet in the ethernet. The network address of the data packet may be a MAC address portion of a frame structure that includes information such as a destination address, a source address, etc. of the data packet. And may also be used to determine the identity of the data packet. In this embodiment, based on the second field and the network address, the identity information of the data packet is accurately determined.

In one embodiment, the second component has stored therein a record table associated with the received data packet. The record table records the identity information of the data packet received by the second component. After the second component receives the data packet, the identity information of the currently received data packet may be compared with the content in the record table, and if the identity information of the currently received data packet is already recorded in the record table, it is determined that other data packets identical to the currently received data packet have been received by the second interface of the second component.

In one embodiment, the identity information of the data packet recorded in the record table includes TAG information (TAG information), which is information calculated using a network address of the data packet, and an FID field (second field). When comparing the identity information of the currently received data packet with the content in the record table, the network address in the identity information of the currently received data packet can be respectively compared with the TAG information, and then the second field in the identity information of the currently received data packet is compared with the second field recorded in the record table. And further determines whether other data packets that are the same as the currently received data packet have been received by the second component.

In one embodiment of the present application, the copying the data packet to generate a plurality of identical data packets includes:

The formats of the data frames of the different types of networks are different, so that the data packet is duplicated based on the frame format of the preset network in a specific application scene, and the data packet can be specifically subjected to framing again, namely the data frame is reconstructed again, and then the corresponding data packet is generated based on the reconstructed data frame. The network address and the second field in the frame structure of each copied data packet are the same, so that after the second component receives the data packet, the identity of the currently received data packet can be judged based on the network address and the second field to determine whether the same data packet has been received.

In one embodiment of the present application, each of the components is connected to the second interfaces of the other components through its respective second interface, and the sending, by using the plurality of second interfaces of the first component, the plurality of data packets to the second interfaces of the second component through different network transmission paths respectively, as shown in fig. 6 and in combination with fig. 4, includes:

S310, the data packet is sent to a second interface of the second component in a first transmission direction through the second interface of the first component.

The first component may send the data packet to the second component, and the data packet may be sent to the plurality of second interfaces of the second component in different transmission directions through the plurality of second interfaces of the first component in parallel. For example, when the network is ring-shaped, the first transmission direction may be a clockwise direction of the network, i.e. through one of the second interfaces of the first component, sending the data packets in the clockwise direction of the network to one of the second interfaces of the second component that is closer to the first component.

And S320, transmitting the data packet to the other second interface of the second component in a second transmission direction through the other second interface of the first component, wherein the first transmission direction is different from the second transmission direction.

Similarly, for example, when the network is ring-shaped, the second transmission direction may be a counter-clockwise direction of the network, i.e. through the further second interface of said first component, the data packets being sent in the counter-clockwise direction of the network to the further second interface of the second component closer to the first component.

This increases the reliability of the data packet when transmitted, since the first transmission direction is different from the second transmission direction. For example, even if the first transmission direction fails, the data packet can be sent to the second component based on the second transmission direction.

In one embodiment of the present application, according to the play type of the data packet and the network address in the frame structure of the data packet, the method transmits the data packet to the first interface of the second component and/or transmits the data packet to the second interface of the other components in the network, as shown in fig. 7, including the following steps:

And S410, when the data packet is determined to be of a unicast type and the destination address in the network address is the first interface of the second component, determining the second component as the target component, transmitting the data packet to the first interface of the second component, and not forwarding the data packet through the second interface of the second component.

Illustratively, unicast type refers to sending a data packet to a single target component. And if the destination address in the network address is the first interface of the second component, the second component is the target component. The first component may simply send the data packet to its second interface via its second interface, which in turn sends the data packet to its first interface. Since the first interface of the second component is connected with the first interface of the second network device (target network device), the data packet can be transmitted to the target network device. And the second component does not forward the data packet through the second interface, so that the task of accurately delivering the data packet to the target network equipment is completed.

And S420, when the data packet is determined to be of a unicast type and the destination address in the network address is not the first interface of the second component, forwarding the data packet to the target component through the second interface of the second component.

Illustratively, if the data packet is of the unicast type and the destination address in the network address is not the first interface of the second component, it is indicated that the target component is not the second component. The data packet needs to be forwarded by the second component. The second interface of the second component is connected with the second interfaces of the other components. The second component forwards the data packet through its second interface to the second interface of the other component to which it is connected. Of course, if the data packet is not sent to the target component, other components can forward the data packet until the data packet is sent to the target component.

And S430, when the data packet is determined to be of a multicast type or a broadcast type, the data packet is sent to the target component, and/or the data packet is forwarded to a plurality of corresponding target components through a second interface of the second component.

For example, if the data packet is of a multicast type or a broadcast type, it indicates that the data packet needs to be sent to multiple target components, or to all components in the network, i.e., all components are target components.

When the data packet is determined to be of a multicast type or a broadcast type, if the second component is a target component, the data packet is transmitted to a second interface of the second component, the data packet is transmitted to a first interface of the second component, and the data packet is further transmitted to target network equipment connected with the second component. Because the target components are multiple, the data packet can be forwarded to multiple corresponding target components through the second interface of the second component, and then the target components send the data packet to the corresponding target network devices.

When the data packet is determined to be of a multicast type or a broadcast type, if the second component is not a target component, the data packet can be forwarded to the second interfaces of the target components step by step through the second interfaces of the second component, and then each target component sends the data packet to the corresponding target network device. Thus realizing the multicast or broadcast operation of the data packet.

In one embodiment of the present application, after the data packets are sent to the second interfaces of the second components respectively through the second interfaces of the first components in different network transmission paths, the method further includes the steps of:

In an exemplary embodiment, the target component may have a plurality of second interfaces, and the first component may send a data packet to each of the plurality of second interfaces of the target component, and if the second component determines that only a unique data packet is received by the second component, it indicates that only one second interface receives the data packet, and other second interfaces do not receive the data packet, so that it may be determined that a data flow failure occurs in the network, and corresponding prompt information is generated.

In one embodiment of the application the method further comprises determining different bytes of an organization code in a frame structure of the data packet as the first field and the second field, respectively.

Illustratively, as shown in FIG. 2, the frame structure of the data packet includes a plurality of fields including an organization code of the org code field. The org code field has 3 bytes, the first byte in the org code field is the FT field, the last two bytes in the org code field are the FID field, which may represent the unique ID of the packet in the Ethernet. In this embodiment, the FT field is determined as a first field, where the first field may be used to characterize whether the data packet needs to be copied. The FID field is determined as a second field, which may represent identity information of the data packet.

In one embodiment, the organization code may also be represented by the first 3 bytes of the source address in the MAC address in the frame structure. So that the org code field can be effectively utilized to perform the above-described network data processing method in the present embodiment.

The embodiment of the application also provides a network data processing device, which is applied to a network, wherein a plurality of different components are arranged in the network, each component corresponds to a respective network device, the components are provided with a first interface and a second interface of different types, the first interface and the second interface have compatible network communication protocols, as shown in fig. 8, and the device comprises:

A determining module configured to determine, if a first interface of a first component receives a data packet sent by a first network device, whether the data packet needs to be duplicated based on a first field in a frame structure of the data packet, wherein the first component corresponds to the first network device.

The network data processing apparatus of the present application is illustratively applied to a network, which may be a local area network such as an ethernet network composed of individual devices in a vehicle or other small local area network. The network is provided with a plurality of components, each corresponding to a respective network device. If the first component corresponds to a first network device, the second component corresponds to a second network device.

And each component is provided with a first interface (such as a G port) and a second interface (such as a T port) of different types, so that the functions of data transmission processing are distinguished based on the interfaces of different types, and the data packet delivery efficiency is improved. The first component receives a data packet sent by the first network device through a first interface of the first component, the determining module analyzes the content of the data packet, and determines whether the data packet needs to be copied or not based on a first field. The data packet has a corresponding frame structure including multiple information therein. In one embodiment, the first interface may be a G-port and the second interface may be a T-port.

For example, the frame structure of an 802.3 protocol-based ethernet includes a plurality of fields, wherein an org code field has 3 bytes, a first byte in the org code field is an FT field, and the second two bytes in the org code field are FID fields, which may represent a unique ID of a data packet in the ethernet. In this embodiment, the FT field is determined as a first field, where the first field may be used to characterize whether the data packet needs to be copied. The FID field is determined as a second field, which may represent identity information of the data packet.

And the copying module is configured to copy the data packets if the data packets need to be copied, so as to generate a plurality of identical data packets.

If it is determined that the data packet needs to be copied based on the first field, the copy module may perform a copy operation on the data packet through the first component, and generate a plurality of data packets having the same content. And respectively processing the plurality of data packets generated after copying through the network.

Illustratively, the first component has a plurality of second interfaces, each of which may transmit data packets relatively independently. In this embodiment, the processing module may send the plurality of data packets to the second interfaces of the second component through the plurality of second interfaces of the first component through different network transmission paths. The method includes sending a data packet to a second interface of a second component in a first transmission direction through a second interface of the first component, and sending another data packet to a second interface of the second component in a second transmission direction through another second interface of the first component. Therefore, the data packet can be transmitted to the second component, and the reliability of data transmission is improved.

In one embodiment, the plurality of data packets are respectively sent to the second interfaces of the second components through the second interfaces of the first components in different network transmission paths, and the second interfaces of the second components receiving the data packets may be different second interfaces. Therefore, the plurality of second interfaces can cooperate with each other to respectively receive the data packets, and the receiving efficiency is improved.

The play type of the data packet includes at least one of unicast, multicast and broadcast. The transmission modes and/or the transmission target network devices of the data packets corresponding to different play types are different. In one embodiment, unicast means that the first component propagates the data packet unidirectionally to a single destination component, multicast means that the first component propagates the data packet to multiple destination components, and broadcast means that the first component propagates the data packet to all components in the network, i.e., all components are destination components.

The frame structure of the data packet has a network address, such as a MAC address part of the frame structure, which includes information such as a destination address, a source address, and the like of the data packet. The network address contains information such as the source and destination of the data packet. Therefore, the processing module of the application can accurately transmit the data packet to the second component and/or other components according to the play type of the data packet and the network address in the frame structure of the data packet. For example, the data packet is transmitted to a second component, which is the target component. Or the data packet is transmitted to other components (such as a third component, a fourth component and the like) through the second component, and then forwarded to the target component by the other components.

When the second component is the target component, the processing module transmits the data packet to a second interface of the second component through the first component, and then transmits the data packet to a first interface of the second component through the second component, wherein the first interface of the second component is connected with the first interface of the target network device, and the data packet is transmitted to the first interface of the target network device through the first interface of the second component, so that the data packet is transmitted to the target network device.

The specific transmission mode further comprises a second interface, wherein the processing module sends the data packet to other components in the network through the first component, and the other components can be non-target components or target components. The processing module can directly forward the data packet to the target component through the first component, or can forward the data packet to the target component step by step through one or more other components, and then send the data packet to the target network device corresponding to the data packet through the target component.
