Description
Technical Field
The present invention relates to the field of data transmission technologies, and in particular, to a method, an apparatus, a device, and a storage medium for sending and receiving ethernet data.
Background
The multiple registration protocol (Multiple Registration Protocol, MRP) is a standard defined in ieee802.1 q. The basic operation of the protocol is that in the same switching network, a certain station and a port perform attribute declaration or cancel, and the station and the port of the opposite end perform corresponding attribute registration or cancellation operation, that is, the process that the attribute passes on a logic path of the registration declaration (Declaration to Registration). The attribute details are defined by a specific MRP upper layer protocol, which includes an MRP Application (MRP Application) scenario or module, for example, virtual local area network (Virtual Local Area Network, VLAN) attributes are defined in multi-VLAN registration protocols (Multiple VLAN Registration Protocol, MVRP), medium access control (Medium Access Control, MAC) attributes are defined in multi-MAC registration protocols (Multiple MAC Registration Protocol, MMRP), and several more complex attributes are defined in multi-stream registration protocols (Multiple Stream Registration Protocol, MSRP), so that the MRP supporting device can quickly propagate its attribute information into the switching network, and can implement the function of "signaling" by using the field information contained in the attributes.
In the transmission of Attribute information, the encapsulation standard of the Data unit is firstly based on an Ethernet frame structure defined by IEEE 802.3, secondly, the Data segment (Data) is a multi-registration protocol Data unit (Multiple Registration Protocol Data Unit, MRPDU) structure defined by IEEE 802.1Q, one MRPDU contains 1-N pieces of information (Message), and finally, the structure of each piece of information is defined by various MRP upper layer protocols, wherein a plurality of attributes (Attribute) defined by specific MRP application can be contained. The encapsulation standard of the data unit refers to the conversion of the attribute data into a standard transport format.
Since the Institute of Electrical and Electronics Engineers (IEEE) of ELECTRICAL AND Electronics Engineers defines an ethernet frame type (ETHER TYPE) for each MRP upper layer protocol, each ethernet frame can only transmit attribute information of one MRP upper layer protocol when attribute data is transmitted, i.e., information in each frame can only belong to one MRP upper layer protocol. Therefore, only one type of MRP equipment attribute information can be transmitted at a time, and the problems of high transmission flow consumption and low transmission efficiency are caused.

The transmitting device 100 and the receiving device 200 in this scenario include, but are not limited to, terminals, bridges, routers, switches, and the like.
Based on the communication scenario shown in fig. 1, fig. 2 is a schematic diagram of a method for sending and receiving ethernet data according to an embodiment of the present invention, where the sending method and the receiving method include:
s201, the transmitting device determines device attribute information of at least two multiple registration protocols to be transmitted.
S202, the sending equipment encapsulates the equipment 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, wherein the data packet comprises the MRPDU and an Ethernet frame structure type identifier, and the Ethernet frame structure type identifier is used for indicating that the MRPDU comprises device attribute information of the at least two multiple registration protocols.
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 device attribute information of the 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 protocol defined device attribute information can be carried in one ethernet frame. In some embodiments, the MRP upper layer protocol includes MMRP, MVRP, MSRP, MIRP. In addition, the invention also provides a Protocol multiplexing (MRP Protocol Mux) component for processing UniMRP Ethernet frames. The device may save network bandwidth by using UniMRP ethernet frame transmission methods of ethernet frame type.
Specifically, when it is determined that the attribute information of the MRP upper layer Protocol to be transmitted is at least two, the attribute information of the two or more MRP upper layer protocols is encapsulated into one MRPDU to be transmitted through a Protocol multiplexing (MRP Protocol Mux) component, so that the purpose of transmitting the attribute information of the two or more MRP upper layer protocols at a time is achieved. And the protocol multiplexing (MRP Protocol Demux) component is used for carrying out decapsulation according to the Ethernet frame structure type identifier to obtain the attribute information of two or more MRP upper layer protocols, so that the receiving and decapsulation of the equipment attribute information of at least two multiple registration protocols are completed, and the subsequent distribution is facilitated.
In use, the Ethernet frame structure type identifies an MRPDU that enables the MRPDU to be identified as one that contains attribute information for two or more MRP upper layer protocols.
In one possible implementation, 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. Illustratively, as shown in fig. 3, the transmission data contains other frame header overheads in addition to the data content field and the ethernet frame structure type, referred to as per-frame overheads (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, consisting essentially of an 8 byte preamble, a 14 byte Ethernet header field, a4 byte 802.1Q priority and VLAN tag field, a4 byte CRC check field, and a 12 byte intra frame gap (Iter-FRAME GAPS, IFG).
In some embodiments, 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 (UniMRP Destination Address) field occupies 6 bytes, and the value is not limited, and one of the addresses may be reserved (MRP Application Reserved) using the MRP application. In some embodiments, uniMRP destination addresses are 01-80-C2-00-00-28.
The UniMRP Ethernet frame type of the application is that the MVRP Ethernet frame, the MSRP Ethernet frame type, the MMRP Ethernet frame type and the MIRP Ethernet frame type can be combined into the UniMRP Ethernet frame type data frame for transmission, thereby reducing the use of FOH.
Furthermore, it should be noted 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 little information (such as only one information), an ethernet frame is also needed to transmit, and other MRP upper layer protocols need to send much information, and cannot multiplex the ethernet frame with little information to transmit. The Ethernet frame type provided by the scheme is as follows: uniMRP Ethernet frame types can be used for multiplexing Ethernet frames, so that the transmission efficiency of the equipment attribute information is improved.
In some embodiments, the ethernet data receiving method further comprises:
s206, when the Ethernet frame structure type identifier indicates that the MRPDU only comprises equipment attribute information of a multiple registration protocol, acquiring the equipment attribute information from the MRPDU according to the Ethernet frame structure type identifier. I.e. when the transmitted MRP device attribute information is only one, it may also be transmitted over UniMRP ethernet frame types.
In some embodiments, after obtaining the device attribute information of the at least two multiple registration protocols, the method further includes: and distributing the equipment 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 kinds of MRP device attribute information, the demultiplexed information needs to be distributed to corresponding MRP applications for reading.
To more systematically describe the above transmission method, the following description is made with reference to the usage scenario diagrams shown in fig. 8 and 9.
Fig. 4 is a schematic diagram of a device attribute information transceiving process of MRP in the prior art, and fig. 5 is a schematic diagram of a device attribute information transceiving process using UniMRP ethernet frame type according to an embodiment of the present invention.
As shown in fig. 4, the transmitting apparatus and the receiving apparatus (Device) do not employ the attribute information transceiving process of the component, and the transmitting apparatus 100 in the switched network needs to transmit attribute information to the receiving apparatus 200. In some embodiments, the MVRP application needs to send MVRP information, and likewise, the MSRP application and the MMRP application need to send corresponding types of information. However, when transmitting MVRP information, the information of the home MVRP protocol is encapsulated in an MRPDU by an encoding (encoding) component, and is transmitted by using an ethernet frame, where the ethernet frame type of the ethernet frame is MVRP, and other types of information cannot be transmitted, and wait for transmission by using additional ethernet frames. When the receiving device 200 receives the ethernet frame, it recognizes that the ethernet frame is an ethernet frame of an MVRP protocol through the ethernet frame type for MVRP, and the decoding (decoding) component decapsulates the information in the MRPDU and distributes the information to the MVRP application for subsequent processing.
As shown in fig. 5, which is a use scenario in which a device uses a protocol demultiplexing component, a transmitting device 100 in a switched network needs to transmit attribute information to a receiving device 200. In some embodiments, the MVRP application needs to send MVRP information, and similarly, the MSRP application and the MMRP application need to send corresponding types of information, where information belonging to multiple protocols is encapsulated into one MRPDU through a protocol demultiplexing component, and sent by using one ethernet frame, where the ethernet frame type of the ethernet frame is UniMRP. When the receiving device 200 receives the ethernet frame, it recognizes that the ethernet frame is an ethernet frame of a composite MRP through the ethernet frame type UniMRP, and the protocol demultiplexing component decapsulates the information in the MRPDU and distributes the information to the corresponding MRP application for subsequent processing. In some embodiments, the protocol de-multiplexing component de-encapsulates the information in the MRPDU before distributing it to MVRP, MSRP, MMRP or MIRP applications.
To more systematically describe the above transmission method, the following description is made in connection with the ethernet frame multiplexing and demultiplexing diagrams shown in fig. 6 and 7.
Fig. 6 is a schematic flow chart of multiplexing ethernet frames by a protocol multiplexer component according to an embodiment of the present invention, and fig. 7 is a schematic flow chart of demultiplexing ethernet frames by a protocol demultiplexer component according to an embodiment of the present invention.
Taking MVRP, MSRP and MMRP application as transmitting devices as an example, as shown in fig. 6, attribute type marking is performed according to attribute information sent by MVRP, MSRP and MMRP application, then attribute is converted into information, the information is encapsulated into MRPDU, the value of the ethernet frame type field is marked as 0xFFFF, the destination address is marked as UniMRP destination address, and then the ethernet frame is sent out.
As shown in fig. 7, taking the ethernet frame sent in fig. 6 as an example, the receiving device monitors UniMRP destination addresses, determines whether the value of the ethernet frame type field is 0xFFFF, when the value of the ethernet frame type field is 0xFFFF, decapsulates the MRPDU into information, converts the information into an attribute, then determines the type of the attribute, and sends the attribute information of the MVRP, the MSRP and the MMRP to corresponding MVRP, MSRP and MMRP applications, respectively. And when the value of the Ethernet frame type field is not 0xFFFF, acquiring the equipment attribute information from the MRPDU according to the Ethernet frame structure type identification.
In practical use, in a topology network, a device node has 10 attributes that need to be propagated to the network, 11 routes to reach all R device nodes. The device nodes are transmission starting points of the attribute information, the transmission points are the number of LANs, and the R device nodes are transmission receiving points of the attribute information.
Before UniMRP ethernet frame structure types of the present application are not used, it is assumed that 2 pieces of attribute information can be attached to each piece of propagation data, that is, one ethernet frame can only contain 2 pieces of attribute data, the D device node needs to send 5 times, and the consumption of FOH in transmission is 42 bytes multiplied by 5 times multiplied by 11 transmission points=2310 bytes in total except the data itself.
After using UniMRP ethernet frame structure types of the present application, it is assumed that each propagated data can be accompanied by 5 pieces of attribute information, i.e. one ethernet frame can only contain 5 pieces of attribute data, the D device node needs to send 2 times, and the consumption of the network traffic in the transmission is 42 bytes multiplied by 2 times multiplied by 11 transmission points=924 bytes except the data itself.
In addition, according to the requirement of the MRP upper layer protocol, the state storage of the attribute information on the equipment has a life cycle, the default value of the timer of the MRP upper layer protocol is 1000 cS, namely, all the attribute information on the equipment is invalidated every 1000 cS, and the propagation process needs to be carried out again. Then about 8M of network traffic can be saved per minute after using this solution.
It should be noted that in practical use, the topology network may be more complex, for example: there are more device nodes. There may be a scenario where multiple device nodes initiate attribute propagation at the same time, so the benefits of using the ethernet information transmission method of the present application may be more obvious.
