Rather, these terms are used only to distinguish one from another. For example, a first information can be termed a second information, and similarly, a second information can also be termed a first information, without departing from the scope of the embodiments of the present application. As used herein, the words "if" and "when" can be interpreted to mean "upon" or "in response to a determination" depending on the context.

[0030] The embodiments of the present application are described in detail below with reference to the drawings, in which examples of the embodiments are shown. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0031] It should be noted that the message sending method provided by any one of the embodiments of the present application can be executed alone or in combination with the possible implementation methods in other embodiments, and can also be executed in combination with any one of the technical solutions in the related art.

[0032] The message sending method and device of the embodiments of the present application are described below with reference to the accompanying drawings.

[0033] Figure 1 A flowchart of a message sending method provided by an embodiment of the present application is shown in FIG. 1. As shown in the figure, the method includes but is not limited to the following steps: Figure 1

[0034] S101, obtaining an undetermined mode message, and determining whether to perform a discard operation on the undetermined mode message.

[0035] It should be noted that a message is a data unit exchanged and transmitted in a network, and it is a basic unit in network communication, used to transmit information between a source address and a destination address. The message can be a data packet in different protocol layers, and the protocol layer usually refers to an OSI (Open System Interconnection) seven-layer protocol model, including: an application layer, a presentation layer, a session layer, a transport layer, a network layer, a data link layer, and a physical layer.

[0036] In a network, when a device wants to communicate with a remote server, data is encapsulated into individual messages, each message containing a source address and a destination address. These messages are transmitted through the network, forwarded by multiple intermediate nodes (routers, switches, etc.), and finally reach the target server. Then the server opens the message, parses the data content therein, and makes a corresponding response according to the source address. The design and parsing of the message follow specific communication protocols, which specify the structure, format of the message, and how to process the data therein. Different applications and protocols can apply different message formats and rules. Encapsulating messages is from upper layer to lower layer (for example, application layer -> transport layer -> network layer -> data link layer -> physical layer), and the parsing and encapsulation of the message is from lower layer to upper layer.

[0037] ​In the process of message transmission, the source address and the destination address usually do not change, unless network address translation is encountered. If the message is transmitted in two layers (data link layer -> physical layer), it can be addressed through MAC (Media Access Control Address, that is, MAC address, which is an address used to confirm the position of a network device, used to uniquely identify a network card in a network. If a device has one or more network cards, each network card needs and will have a unique MAC address. The MAC address, also known as the physical address or hardware address, is burned on the flash chip of the network card by the network device manufacturer. The MAC address, like the ID number on an ID card, is unique.) Addressing; if the message is transmitted in three layers (network layer -> data link layer -> physical layer), as an example, for a multi-modal network environment, it can be addressed through IP (Internet Protocol Address, that is, IP address, also known as Internet Protocol address. IP address is a unified address format provided by IP protocol, which allocates a logical address for each network and each host on the Internet, thereby shielding the difference between physical addresses) addressing, or content identification, or identity identification, or geospatial identification, etc. Further, the message is called data in the application layer, presentation layer and session layer, called segment in the transport layer, called packet in the network layer, called frame in the data link layer, and called bit in the physical layer.

[0038] Figure 3 Various modal message sending scenarios provided by the embodiments of the present application are shown. As shown in Figure 3 In a multi-modal network environment, some devices only support a small number of modes. Network device A only supports mode X, and network device A obtains mode X traffic from the server for user use. Network device B only supports mode Y, and network device B obtains mode Y traffic from the server for user use. For unidentified modes (i.e., unidentified modes, for network device A, mode Y is an unidentified mode; for network device B, mode X is an unidentified mode), it needs to be sent to other devices through an inter-modal interface for processing. Current network technology cannot determine which three-layer (network layer -> data link layer -> physical layer) processing module to use to process the unidentified mode message, and the device can only discard the unidentified mode message, resulting in waste of data resources. For example, mode Y traffic cannot be transmitted to the corresponding user of mode X network environment, and mode Y traffic is directly discarded.

[0039] Further, Figure 4 The real-time message processing flow provided by the embodiments of the present application is shown. As shown in Figure 4As shown, the obtaining of the indefinite modal message includes: querying the modal type supported by the device according to the protocol of the received real-time message, if the result of the modal identification shows a known modal, the real-time message is processed according to the known modal message processing flow; if the result of the modal identification shows an unknown modal, that is, the modal of the real-time message does not match the modal in the modal type table, the real-time message is processed according to the indefinite modal message processing flow, and then it is judged whether the indefinite modal message is supported by the device, if not, the indefinite modal message is discarded.

[0040] S102, in response to the indefinite modal message not being discarded, judging whether the indefinite modal message is a first indefinite modal message with a forwarding record.

[0041] It should be noted that the message received by the current device is sent by the sending device, when the number of modes supported by the sending device is more than the number of modes supported by the current device, the current device will have a modal miss, that is, an indefinite modal message. The current device extracts a plurality of parameters (the parameters should be selected according to the actual use scene) of the indefinite modal message and matches the configuration table, if the matching is successful, the indefinite modal message is not discarded, otherwise the indefinite modal message is discarded.

[0042] Further, after the first indefinite modal message hit by the current device performs the forwarding operation, a state will be recorded in the indefinite modal cache table, if the current device continues to receive the same message as the first indefinite modal message hit by the current device, and the message is executed to forward, the indefinite modal cache table has the forwarding record of the message, that is, the forwarding record is effective, the message belongs to the "white list" of the current device, and the indefinite modal message with the forwarding record is recorded as the first indefinite modal message. The indefinite modal message not in the "white list" of the current device is discarded.

[0043] S103, in response to the indefinite modal message being the first indefinite modal message, determining the destination address corresponding to the first indefinite modal message, and performing a sending operation on the first indefinite modal message according to the destination address.

[0044] It should be noted that the sending process of the first indefinite modal message is similar to the sending process of the known modal message, when the current device sends the first indefinite modal message, the network node sends the first indefinite modal message to the next node according to the destination address information of the first indefinite modal message, and transfers the first indefinite modal message to the node of the destination address node by node. Specifically, after each node receives the first indefinite modal message and checks it, the node temporarily stores the message, and then finds the address of the next node using the routing information, and then transmits the entire message to the next node.

[0045] It should be noted that the undetermined mode cache table is usually provided with a timeout aging mechanism, which can avoid current device resource exhaustion, and also solve the problem that the current device is waiting for a long time due to the fact that the first undetermined mode packet is not responded in time by the downstream device due to packet loss and other reasons. If the forwarding record in the undetermined mode cache table is not effective after a certain time (as an example, it can be 10 seconds), the undetermined mode cache table is deleted, and if the same packet as the first undetermined mode packet is received subsequently, the first undetermined mode packet is reprocessed. On the other hand, the undetermined mode cache table can also be set with an upper limit value (as an example, the upper limit value can be 10000), and when the number of undetermined mode cache tables exceeds the upper limit value, the subsequent undetermined mode packets are discarded directly, thereby avoiding the exhaustion of the memory resources of the device by the downstream device sending a large number of undefined modes maliciously or abnormally.

[0046] In summary, by judging whether the undetermined mode packet is the first undetermined mode packet with a forwarding record, and transmitting the first undetermined mode packet according to the destination address, the cross-device forwarding of the undetermined mode packet is realized, and at the same time, the undetermined mode packet can avoid consuming too much link bandwidth, which has a wide range of use scenarios.

[0047] Figure 2 The flowchart of another packet transmission method provided by the embodiments of the present application is shown in FIG. 6. As shown in FIG. 6, the method includes but is not limited to the following steps: Figure 2

[0048] S201, receiving a real-time packet and judging whether the real-time packet is an undetermined mode packet.

[0049] It should be noted that in a feasible embodiment, the received real-time packet is identified by protocol to obtain the protocol field of the real-time packet. Specifically, the real-time packet is identified by protocol based on the physical layer parameters and data link layer parameters of the real-time packet to obtain the protocol field of the real-time packet.

[0050] The protocol field is used to judge whether the real-time packet is the undetermined mode packet. Specifically, the modal type table corresponding to the real-time packet is queried according to the protocol field; if the protocol field is hit by a mode in the modal type table, it is determined that the real-time packet is a known mode packet, and the known mode packet is processed according to the known packet processing flow. Further, the known mode packet is transmitted based on the destination address corresponding to the real-time packet; if the protocol field is not hit by a mode in the modal type table, it is determined that the real-time packet is the undetermined mode packet, and the undetermined mode packet is processed according to the undetermined mode packet processing flow.

[0051] ​For a more detailed description of step S201, please refer to the relevant content in the above embodiments, which will not be repeated here.

[0052] S202, in response to the real-time message being an undefined modal message, determine whether to discard the undefined modal message.

[0053] It should be noted that, in one feasible embodiment, in response to the real-time message being an undefined modal message, a configuration table for filtering the undefined modal message is obtained; based on the configuration table, it is determined whether to discard the undefined modal message. Specifically, the modality code and source interface of the undefined modal message are obtained; if the modality code and source interface of the undefined modal message are not matched by the configuration table, the undefined modal message is discarded; if the modality code and source interface of the undefined modal message are matched by the configuration table, it is determined that the undefined modal message has not been discarded.

[0054] For a further detailed description of step S202, please refer to the relevant content in the above embodiments, which will not be repeated here.

[0055] S203, in response to the fact that no discard operation was performed on the undetermined modality message, determine whether the undetermined modality message is a first undetermined modality message with forwarding records.

[0056] It should be noted that, in one feasible embodiment, in response to the operation that the undefined mode packet is not dropped, the forwarding record tag of the undefined mode packet is obtained based on the undefined mode cache table corresponding to the undefined mode packet. As an example, such as... Figure 2 As shown, the destination interface typically routes based on the current device's destination address and ingress interface. In this embodiment, the destination interface can be represented as the destination address. If the current device forwards an undefined mode packet, but the destination interface does not receive the undefined mode packet, the undefined mode cache table marks the above state as the first state. If the current device forwards an undefined mode packet, and the destination interface receives the undefined mode packet (i.e., there is a forwarding record for the undefined mode packet in the undefined mode cache table), meaning that the undefined mode packet is transmitted between the current device and the destination interface, then the undefined mode cache table marks the above state as the second state. Based on the second state, the undefined mode packet is the first undefined mode packet. If the destination interface receives an undefined mode packet—specifically, the first undefined mode packet—but the destination interface does not receive any more undefined mode packets from the current device, and therefore there is no forwarding record for the undefined mode packet in the undefined mode cache table, the undefined mode cache table can be updated to the first state.

[0057] For a further detailed description of step S203, please refer to the relevant content in the above embodiments, which will not be repeated here.

[0058] S204, in response to the unconfirmed mode message being the first unconfirmed mode message, determining a destination address corresponding to the first unconfirmed mode message, and sending the first unconfirmed mode message according to the destination address.

[0059] For a detailed description of step S204, please refer to the description of the related content in the above embodiments, which will not be repeated here.

[0060] In summary, by judging whether the unconfirmed mode message is the first unconfirmed mode message with a forwarding record, and sending the first unconfirmed mode message according to the destination address, the cross-device forwarding of the unconfirmed mode message is realized, and at the same time, the unconfirmed mode message can avoid consuming too much link bandwidth, which has a wide range of use scenarios.
