Multiple Registration Protocol (MRP) is a standard defined in IEEE802.1Q.

The attribute details are defined by the specific MRP upper-layer protocol. The MRP upper-layer protocol includes MRP Application (MRP Application) scenarios or modules. For example, the Virtual Local Area Network (Virtual Local Area Network) is defined in the Multiple VLAN Registration Protocol (MVRP). , VLAN) attributes, Medium Access Control (MAC) attributes are defined in Multiple MAC Registration Protocol (MMRP), and Medium Access Control (MAC) attributes are defined in Multiple Stream Registration Protocol (MSRP) For several more complex attributes, devices that support MRP can quickly spread their own attribute information to the switching network, and use the field information contained in the attributes to achieve the function of "signaling".

FIG. 1 is a communication scenario of Ethernet data transmission provided by an embodiment of the present invention. A sending device 100 and a receiving device 200 are connected to a network through an Ethernet network, and the sending device 100 sends a data packet to the receiving device through the Ethernet. The data packet includes: The multiple registration protocol data unit MRPDU and the Ethernet frame structure type identifier, where the Ethernet frame structure type identifier is used to indicate that the MRPDU includes device attribute information of at least two multiple registration protocols. The sending device 100 and the receiving device 100 in this scenario include but are not limited to terminals, network bridges, routers, switches, and the like.

Based on the communication scenario described in FIG. 1 , FIG. 2 is an Ethernet data sending method and a receiving method provided by an embodiment of the present invention. The sending method and the receiving method include:

S201. The sending device determines the device attribute information of at least two multiple registration protocols to be sent.

S202: The sending device encapsulates the device attribute information of the at least two multiple registration protocols into a multiple registration protocol data unit MRPDU.

S203. The sending device sends a data packet to the receiving device, where the data packet includes the MRPDU and an Ethernet frame structure type identifier, where the Ethernet frame structure type identifier is used to indicate that the MRPDU includes the at least two multiplexed Device attribute information for the registration protocol.

S204, the receiving device 200 receives a data packet from the transmitting device, where the data packet includes an MRPDU and an Ethernet frame structure type identifier.

S205, when the Ethernet frame structure type identifier indicates that the MRPDU includes device attribute information of at least two multiple registration protocols, the receiving device 200 decapsulates the MRPDU according to the Ethernet frame structure type identifier to obtain the Describe the device attribute information of at least two multiple registration protocols.

In some embodiments, the present invention provides an Ethernet frame type: UniMRP Ethernet frame type, by using this type of Ethernet frame type, a plurality of different MRP upper layer protocols can be carried in one Ethernet frame. Device attribute information. In some embodiments, MRP upper layer protocols include MMRP, MVRP, MSRP, MIRP. In addition, the present invention also provides a protocol multiplexing (MRP Protocol Mux) component for processing UniMRP Ethernet frames. Devices can save network bandwidth by using the Ethernet frame transmission method of the UniMRP Ethernet frame type.

Specifically, when it is determined that the attribute information of the MRP upper layer protocol to be sent is at least two types, the attribute information of the above two or more MRP upper layer protocols is encapsulated into one through a protocol multiplexing (MRP Protocol Mux) component. It is sent in the MRPDU to achieve the purpose of being able to transmit the attribute information of two or more MRP upper layer protocols at a time. Through the protocol multiplexing (MRP Protocol Demux) component, decapsulation is carried out according to the Ethernet frame structure type identifier, and the attribute information of two or more MRP upper layer protocols is obtained, and the device attribute information of at least two multiple registration protocols is completed. Receive and decapsulate for subsequent distribution.

When used, the Ethernet frame structure type identifier enables the MRPDU to be identified as an MRPDU containing attribute information of two or more MRP upper layer protocols.

In a possible implementation manner, the frame structure of the data packet includes, in addition to the data content field and the Ethernet frame structure type, a destination address, an extended destination address, a redundancy field and a check field. Exemplarily, as shown in FIG. 3 , in addition to the data content field and the Ethernet frame structure type, the transmission data also includes other frame header overheads called perFrameOverhead (FOH). The FOH includes a destination address, an extended destination address, a redundancy field and a check field. For 802.3 Ethernet FOH is 42 bytes, mainly including 8 bytes of preamble, 14 bytes of Ethernet header field, 4 bytes of 802.1Q priority and VLAN tag fields, 4 bytes CRC check field and 12-byte internal frame gaps (Iter-frame gaps, IFG).

In some embodiments, the UniMRP Ethernet Frame Type field occupies 2 bytes. In some embodiments, the value is 0xFFFF (IEEE reserved field).

In some embodiments, the UniMRP Destination Address field occupies 6 bytes, and the value is not limited, and one of the MRP Application Reserved (MRP Application Reserved) addresses may be used. In some embodiments, the UniMRP destination address is 01-80-C2-00-00-28.

The UniMRP Ethernet frame type of the present application is that the data frames of MVRP Ethernet frame, MSRP Ethernet frame type, MMRP Ethernet frame type, MIRP Ethernet frame type can be merged into the data frame of UniMRP Ethernet frame type for transmission, Thereby reducing the use of FOH.

In addition, it is worth noting that in the prior art, different MRP upper-layer protocols send information to maintain different queues. When a certain MRP upper-layer protocol needs to send very little information (for example, only one), it also needs an Ethernet frame for transmission. However, other MRP upper-layer protocols need to send a lot of information, and cannot multiplex Ethernet frames with little information for transmission. The Ethernet frame type provided by this solution: UniMRP Ethernet frame type can multiplex Ethernet frames and improve the transmission efficiency of device attribute information.

In some embodiments, the Ethernet data receiving method further includes:

S206. When the Ethernet frame structure type identifier indicates that the MRPDU only includes device attribute information of one multiple registration protocol, acquire the device attribute information from the MRPDU according to the Ethernet frame structure type identifier. That is, when only one type of MRP device attribute information is sent, it can also be sent through the UniMRP Ethernet frame type.

In some embodiments, after obtaining the device attribute information of the at least two multiple registration protocols, the method further includes: distributing the device attribute information of the at least two multiple registration protocols to corresponding multiple registration protocol applications. That is, when the obtained demultiplexed information is two or more types of MRP device attribute information, it needs to be distributed to the corresponding MRP application for reading.

In order to describe the above transmission method more systematically, the following description is made with reference to the schematic diagrams of usage scenarios shown in FIG. 8 and FIG. 9 .

FIG. 4 is a schematic diagram of a process of sending and receiving device attribute information of MRP in the prior art, and FIG. 5 is a schematic diagram of a process of sending and receiving device attribute information using the UniMRP Ethernet frame type according to an embodiment of the present invention.

As shown in FIG. 4 , the sending device and the receiving device (Device) do not adopt the process of sending and receiving attribute information of components, and the sending device 100 in the switching network needs to send the attribute information to the receiving device 200 . In some embodiments, the MVRP application needs to send the MVRP information, and similarly, the MSRP application and the MMRP application also need to send the corresponding type of information. However, during data link transmission, only one type of information can be sent at a time. When sending MVRP information, the information belonging to the MVRP protocol is encapsulated into an MRPDU through an encode component, and sent using an Ethernet frame. The Ethernet frame type of the network frame is MVRP, and other types of information cannot be sent, waiting to be sent using additional Ethernet frames. After receiving the Ethernet frame, the receiving device 200 recognizes that it is an Ethernet frame of the MVRP protocol by using the Ethernet frame type as MVRP, and decapsulates the information in the MRPDU through the decoding component and distributes it to the MVRP application for follow-up. processing.

As shown in FIG. 5 , it is a usage scenario in which the device uses a protocol demultiplexing component, and the sending device 100 in the switching network needs to send attribute information to the receiving device 200 . In some embodiments, MVRP applications need to send MVRP information. Similarly, MSRP applications and MMRP applications also need to send corresponding types of information. At this time, information belonging to multiple protocols is encapsulated into one MRPDU through the protocol multiplexing component. , an Ethernet frame is used for sending, and the Ethernet frame type of the Ethernet frame is UniMRP. After receiving the Ethernet frame, the receiving device 200 identifies that it is a composite MRP Ethernet frame through the Ethernet frame type being UniMRP, and decapsulates the information in the MRPDU through the protocol multiplexing component and distributes it to the corresponding The MRP application performs subsequent processing. In some embodiments, the protocol demultiplexing component decapsulates the information in the MRPDU for distribution to MVRP, MSRP, MMRP or MIRP applications.

In order to describe the above transmission method more systematically, the following description will be given in conjunction with the schematic diagrams of Ethernet frame multiplexing and demultiplexing shown in FIG. 6 and FIG. 7 .

FIG. 6 is a schematic flowchart of multiplexing Ethernet frames through a protocol multiplexer component according to an embodiment of the present invention, and FIG. 7 is a pair of Ethernet frames through a protocol multiplexer component according to an embodiment of the present invention. A schematic diagram of the flow of Ethernet frame demultiplexing.

As shown in Figure 6, taking MVRP, MSRP, and MMRP applications as the sending device as an example, the attribute type is marked according to the attribute information sent by the MVRP, MSRP, and MMRP applications, and then the attributes are converted into information, and the information is encapsulated into MRPDUs and marked. The value of the Ethernet frame type field is 0xFFFF, marking the destination address as the UniMRP destination address, and then sending the Ethernet frame.

As shown in Figure 7, taking the Ethernet frame sent in Figure 6 as an example, the receiving device monitors the UniMRP destination address and determines whether the value of the Ethernet frame type field is 0xFFFF. When the value of the Ethernet frame type field is 0xFFFF, it will The MRPDU is decapsulated into information, the information is converted into attributes, the type of attributes is then determined, and the attribute information of MVRP, MSRP and MMRP is sent to the corresponding MVRP, MSRP and MMRP applications respectively. When the value of the Ethernet frame type field is not 0xFFFF, the device attribute information is acquired from the MRPDU according to the Ethernet frame structure type identifier.

In actual use, in a topology network, a device node has 10 attributes that need to be propagated to the network, and 11 routes can be used to reach all R device nodes. The device node is the originating point of propagating the attribute information, the propagating point is the number of LANs, and the R device node is the propagating and receiving point of the attribute information.

Before the UniMRP Ethernet frame structure type of the present application is not used, it is assumed that only 2 attribute information can be attached to each transmission data, that is, an Ethernet frame can only contain 2 attribute data, and the D device node needs to send 5 times. In addition to the data itself, the consumption of network traffic is 42 bytes multiplied by 5 times multiplied by 11 transmission points = 2310 bytes in total.

After using the UniMRP Ethernet frame structure type of the present application, it is assumed that 5 attribute information can be attached to each transmission data, that is, an Ethernet frame can only contain 5 attribute data, and the D device node needs to send twice, and the network is transmitted during transmission. In addition to the data itself, the consumption of traffic is 42 bytes multiplied by 2 times multiplied by 11 transmission points = 924 bytes in total.

In addition, according to the requirements of the MRP upper-layer protocol, the state of the attribute information on the device has a life cycle. The default value of the timer of the MRP upper-layer protocol is 1000 centiseconds, that is, all attribute information on the device is invalid every 1000 centiseconds. Repeat the above propagation process. Then after using this solution, about 8M of network traffic can be saved per minute.

It is worth noting that, in actual use, the topology network will be more complex, for example, there are more device nodes. There may also be scenarios in which multiple device nodes initiate attribute propagation at the same time, so the benefits of using the Ethernet information transmission method of the present application will be more obvious.
