The embodiment of the application provides a message processing method, message processing equipment and a storage medium, which bypass a thick and heavy core TCP/IP protocol stack, effectively reduce the forwarding delay of messages among Internet of things equipment, reduce the consumption of CPU processing resources, provide more CPU processing resources for other applications and enable processing response to be provided more smoothly.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The technical solution in the present application will be described below with reference to the accompanying drawings.

At present, in an LAN, to implement an interaction flow of a C/S communication packet between one internet of things device and another internet of things device through a Wi-Fi router, a data packet may be forwarded to an opposite internet of things device based on the Wi-Fi router after operations such as encapsulation and decapsulation of the data packet are performed through a core TCP/IP protocol stack in the device and a core TCP/IP protocol stack in the router. For example, please refer to fig. 1, which is a communication flow chart based on a kernel TCP/IP protocol stack provided in the conventional scheme. As can be seen from fig. 1, if a first internet of things device wants to report a data packet to a second internet of things device in a different network segment, an application layer in the first internet of things device needs to send the data packet to a kernel TCP/IP protocol stack in the first internet of things device, so that the data packet can be encapsulated, and then the encapsulated data packet is sent to a router through a network card driver. After receiving the encapsulated data message sent by the first internet of things device, the router forwards the encapsulated data message to a kernel protocol stack of the router from the network card driver, so that the encapsulated data message is decapsulated and encapsulated into a data message which can be identified by the second internet of things device, and then the data message is forwarded to the corresponding network card driver through a routing forwarding rule and is forwarded to the second internet of things device by the network card driver. Therefore, when the network card driver in the second networking device receives the data message, the data message can be sent to the corresponding application layer only after passing through the kernel TCP/IP protocol stack in the second networking device. Obviously, the data message is transmitted, received and forwarded based on the core TCP/IP protocol stack, and due to more protocol layers and more complex interaction flows, the message forwarding use time delay is longer and a large amount of CPU processing resources are consumed; and the throughput rate of a core TCP/IP protocol stack is low, so that the physical bandwidth cannot be fully utilized to transmit large data among the Internet of things devices based on Wi-Fi transmission.

Therefore, in order to solve the above technical problem, an embodiment of the present application provides a message processing method, which can be applied in a scenario of an internet of things based on wireless communication in a LAN. For example: the intelligent household Internet of things scene comprises household Internet of things devices such as an intelligent refrigerator, a sweeper, an air conditioner, a sound box and/or a television, or comprises terminal devices such as a smart phone and a tablet. In practical application, other scenes of the internet of things can be provided, and specific description will not be limited in the embodiment of the present application. It should be understood that the above mentioned wireless communication may include but is not limited to Wi-Fi, bluetooth, etc., and the type of the above mentioned wireless communication is not limited in the embodiments of the present application. In the embodiments of the present application, Wi-Fi is used as an example for illustration.

It should be understood that the first and second internet-of-things devices described above may include, but are not limited to: the intelligent refrigerator, the sweeper, the air conditioner, the sound box, the television, the smart phone or the tablet and the like are not specifically limited.

Fig. 2 shows a schematic diagram of a possible system framework of an embodiment of the present application. As can be seen from fig. 2, in the embodiment of the present application, the flow of message processing does not need to pass through a core TCP/IP protocol stack, but a pass-through module is respectively added to the first internet of things device, the network device, and the second internet of things device, for example: the method comprises the steps of adding a first direct connection module in first Internet of things equipment, adding a second direct connection module in network equipment and adding a third direct connection module in second Internet of things equipment. Therefore, when the first message acquired from the application layer is a through message, the first internet of things device encapsulates the first message only through the ethernet protocol in the newly added first through module, and transmits the encapsulated second message to the network device through the network card driver. And after the network device receives the second message based on the network card driver corresponding to the first internet of things device and decapsulates the second message, when the first message included in the second message is determined to be a direct message, the network device only needs to forward the second message in the second direct module according to the MAC address, and forward the second message to the second internet of things device through the network card driver corresponding to the second internet of things device. When the second networking device receives the second message through the network card drive, the second message can also be uploaded to the corresponding application layer through the third direct-connection module.

It should be understood that the first internet of things device and the second internet of things device may include, but are not limited to, a smart refrigerator, an air conditioner, a sweeper, a smart phone, and the like. Network devices may include, but are not limited to, routers and the like. In addition, in practical applications, the system framework described in fig. 2 may also be applied to a scenario of internet of things including a plurality of internet of things devices such as a third internet of things device, a fourth internet of things device, and a plurality of corresponding network devices, and the number of the internet of things devices and the number of the network devices are not limited in this application. For ease of understanding, the embodiments of the present application are described only from the perspective of interaction of three devices, namely, a first internet of things device, a network device, and a second internet of things device.

It should be noted that the above-mentioned direct message may be obtained by a user through self-definition according to requirements, that is, the direct message may be identified by using a self-defined type such as an EtherType reserved type.

For example, please refer to fig. 3, which is a schematic diagram of a custom direct message provided in an embodiment of the present application. As shown in fig. 3, the pass-through message may include a target Media Access Control (MAC) address of 6 bytes, a source MAC address of 6 bytes, a protocol type of 2 bytes, and the like. The target MAC address is mainly used for identifying the Internet of things equipment for receiving the direct message, such as the second Internet of things equipment mentioned above; the 2-byte protocol type is mainly used for reflecting that the message to be transmitted, received or forwarded is a through message, namely a user-defined message. The field value in the protocol type may be defined according to IEEE802.3 protocol standard, as long as the field value does not conflict with the field value in the existing protocols such as the current IP protocol, TCP protocol, Address Resolution Protocol (ARP), etc., and the field value is less than 1536, which is not specifically described in this embodiment.

The following describes a method for message processing in the present application from an interaction perspective. Referring to fig. 4, a schematic diagram of an embodiment of a method for processing a message according to an embodiment of the present application is shown, where the method includes:

401. the first Internet of things equipment acquires the first message.

The first internet of things device can obtain the first message on the application layer.

402. And when the first message is a direct message, the first Internet of things equipment encapsulates the first message into a second message according to the Ethernet protocol, wherein the second message comprises the target MAC address and the first message.

In an embodiment, when obtaining the first message, the first internet of things device may first determine whether the first message is a user-defined direct message. If the first message is a direct message, the first internet of things device may directly package the first message into a second message according to an ethernet protocol. Specifically, the first internet of things device adds an ethernet header to a message header of the first message, so that the second message obtained after encapsulation can be sent to the network device through a corresponding network interface. It is understood that the second packet includes the destination MAC address and the first packet.

Illustratively, when the first message is a direct message, before the first internet of things device encapsulates the first message into the second message according to the ethernet protocol, the method may further include: and the first Internet of things equipment determines that the first message is a direct message according to the protocol type field in the first message.

Since the first packet carries the corresponding protocol type field, the first internet of things device may determine whether the first packet is a direct packet based on the protocol type field in the first packet. The direct connection message can be understood as a user-defined message, and the field value of the protocol type field in the direct connection message can be defined according to the IEEE802.3 protocol standard as long as the field value does not conflict with the field value in the existing protocols such as the current IP protocol, the TCP protocol, the ARP protocol, and the like, and the field value is less than 1536. For example: the first internet of things device may determine whether a field value of the protocol type field in the first message is a field value in an existing protocol, such as "0 × 0800 (field value of IP protocol)", "0 × 86DD (field value of internet protocol version 6 (IPv 6)) and the like. If the field value of the protocol type field in the first message is not the field value in the existing protocol, it can be determined that the first message is a through message.

Specifically, the flow of processing the packet by the first internet of things device is further described with reference to fig. 5. Fig. 5 is a schematic diagram of adding a first pass-through module to a first internet of things device provided in the embodiment of the present application. The first pass-through module mentioned above has at least the following functions: providing an Application Programming Interface (API) for an application program on an application layer; the method can support the receiving and sending queues of the through messages, configure the buffer size of the queues and support the receiving and sending scheduling of the receiving and sending queues; the encapsulation and the decapsulation of the direct message are supported; and supporting interaction with a network card driver and the like.

Therefore, on the basis of the corresponding function of the first pass-through module, as shown in fig. 5, the first packet is obtained from the application program on the application layer, and then when it is determined that the first packet is a pass-through packet, the first packet is cached to the sending queue in the newly added first pass-through module based on the API transceiving interface. And further, by utilizing the functions of message encapsulation, decapsulation and the like supported by the first pass-through module, the first pass-through module encapsulates the first message into a second message based on the Ethernet protocol. And finally, the first direct connection module sends the second message to the network card driver.

It should be noted that, the above-mentioned first internet of things device is mainly described from the perspective of sending a message, and in practical application, the first internet of things device may also receive a message from a second internet of things device. Thus, the flow of processing the received message from the second networked device through the first pass-through module (dotted line portion) is also shown in fig. 5. For example, suppose that the network card driver in the first internet of things device receives the encapsulated second message from the network device, and then sends the second message to the first pass-through module. In this way, the first direct module judges whether the first message included in the second message is the self-defined direct message after analyzing the second message. If the first message is a direct message, the first direct module directly caches the first message in the receiving queue, and sends the first message received from the second networking equipment to an application program of an application layer through the API receiving and sending interface, so that message circulation between the first networking equipment and the second networking equipment is completed.

It can be understood that, if the first direct module determines that the first packet is not a direct packet, the first direct module directly sends the first packet to the kernel TCP/IP protocol stack, and processes the first packet through the kernel TCP/IP protocol stack.

403. And the first Internet of things equipment sends a second message to the network equipment.

The first internet of things device can send the second message to the network device through Wi-Fi and other wireless communication.

404. And the network equipment analyzes the second message to obtain the target MAC address and the first message.

405. The network equipment judges whether the first message is a direct message or not based on the protocol type field in the first message.

In the embodiment, after parsing the first packet and the target MAC address included in the second packet, the network device may further determine whether the first packet is a direct packet based on a protocol type field in the first packet. For example: the network device may determine whether a field value of the protocol type field in the first packet is a field value in an existing protocol, such as "0 × 0806(a field value of ARP protocol)", "0 × 86DD (a field value of IPv6 protocol)". If the field value of the protocol type field in the first message is not the field value in the existing protocol, the network device may determine that the first message is a through message.

406. And when the protocol type field in the first message reflects that the first message is a direct message, the network equipment sends a second message to the second networking equipment based on the target MAC address.

When the network device determines that the first packet is a direct packet, the network device does not need to process the first packet through a complex kernel TCP/IP protocol stack, and forwards the second packet to the second network device based on the target MAC address.

In some embodiments, the method may further comprise: and the network equipment inquires second networking equipment corresponding to the target MAC address from the preset MAC forwarding relation table. It can be understood that the network device may record, in the MAC forwarding relationship table in advance, a MAC address corresponding to each accessed internet of things device in the LAN. Therefore, when the network device analyzes the MAC address in the second message, the corresponding second networking device can be determined based on the preset MAC forwarding relation table.

A process of processing a packet by a network device is further described with reference to fig. 6, and with reference to fig. 6, a schematic diagram of adding a second pass-through module in the network device provided in the embodiment of the present application is provided. The second pass-through module mentioned above may also be referred to as a router pass-through module, and has at least the following functions: recording MAC addresses of each access device in the LAN; the direct connection message is forwarded according to the MAC address; and supporting interaction with a network card driver and the like.

On the basis of the corresponding function of the second pass-through module, as shown in fig. 6, after receiving a second message sent from the first internet of things device from the network card driver of the input interface, the second pass-through module analyzes the second message, and determines that the first message is obtained through analysis. When the second direct connection module judges that the first message is a direct connection message, the second message can be forwarded to the network card driver of the output interface according to the target MAC address, and the network card driver of the output interface sends the second message to the second networking equipment corresponding to the target MAC address through Wi-Fi and other wireless communication.

It can be understood that, if the second pass-through module determines that the first packet is not a pass-through packet, the second pass-through module directly sends the first packet to the kernel TCP/IP protocol stack, and processes the first packet through the kernel TCP/IP protocol stack.

407. And the second networking equipment analyzes the second message to obtain the first message.

408. And the second networking equipment judges whether the first message is a direct message or not based on the protocol type field in the first message.

In the embodiment, after the second internet-of-things device receives the second message sent by the network device through wireless communication such as Wi-Fi, the second message is analyzed, so that the first message included in the second message can be obtained. At this time, the second networking device needs to further judge and process the first message, mainly to avoid that the straight-through message is processed by a complex kernel TCP/IP protocol stack, which results in longer message transmission delay, more CPU resources consumption, and the like. For example: the second network device may determine whether the field value of the protocol type field in the first packet is a field value in an existing protocol, such as "0 × 0806 (field value of ARP)", "0 × 0800 (field value of IP protocol)". If the field value of the protocol type field in the first message is not the field value in the existing protocol, the second network device may determine that the first message is a direct message.

409. And when the first message is a direct message, the second networking equipment caches the first message in the receiving queue.

In the embodiment, when the second network device determines that the first packet is a direct packet, the first packet may be directly cached in the receive queue without being processed by the core TCP/IP protocol stack, and may subsequently reach the application program on the application layer.

It should be noted that a third direct-connection module may also be added to the second networking device, and functions of the third direct-connection module may be understood with reference to the first direct-connection module described in fig. 5, which will not be described herein. Specifically, as will be understood with reference to the portion described by the dotted line in fig. 5, when the network card driver in the second networking device receives the second message, the network card driver sends the second message to the third pass-through module; and after the third direct connection module analyzes the second message, judging whether the first message included in the second message is a self-defined direct connection message. If the first message is a direct message, the third direct module directly caches the first message in the receiving queue, and sends the first message received from the second internet-of-things equipment to an application program of an application layer through the API receiving and sending interface, so that message circulation with the first internet-of-things equipment is completed.

It can be understood that, if the third direct connection module determines that the first packet is not a direct connection packet, the third direct connection module directly sends the first packet to the kernel TCP/IP protocol stack, and processes the first packet through the kernel TCP/IP protocol stack.

In the embodiment of the application, the first internet of things device can directly package the first message as the second message based on the ethernet protocol when judging that the first message is the direct message by self-defining the direct message, and then send the second message to the network device through wireless communication. After receiving the second message, the network device analyzes the corresponding target MAC address and the first message, and forwards the second message to the second networking device based on the target MAC address. And the second networking equipment analyzes the second message and judges whether the first packet included in the second message is a direct message or not, and when the first message is the direct message, the second networking equipment directly caches the first message to the receiving queue. By the mode, the message is transmitted and received among the Internet of things devices without being processed by a complex kernel TCP/IP protocol stack, so that the processes of scheduling, queuing, caching, message copying and the like of each layer of protocol stack in the kernel TCP/IP protocol stack are avoided, the message forwarding delay can be effectively reduced, and the user experience is improved; and CPU resource consumption is reduced, more CPU processing resources are provided for other applications, and processing response is more smoothly provided. In addition, the communication capability of a thick and heavy inner core TCP/IP protocol stack is bypassed, the length of a TCP/IP message header is saved, and the utilization rate of physical bandwidth is improved.
