When the user equipment 1 needs to send an uplink message to the user equipment 2, the user equipment 1 determines gateway equipment needing to send the uplink message according to a preset first hash algorithm; assuming that the determined gateway device is the gateway device 11, the user device 1 sends the uplink message to the gateway device 11; after receiving the uplink packet, the gateway device 11 establishes a fast forwarding table based on the uplink packet, performs SDWAN tunnel encapsulation on the uplink packet and then sends the uplink packet to the gateway device 21, and the gateway device 21 performs SDWAN tunnel decapsulation on the encapsulated uplink packet to obtain the uplink packet, and sends the uplink packet to the user device 2 for processing.
When receiving a downlink message which is sent by the user equipment 2 and needs to be sent to the user equipment 1, the subsequent gateway equipment 21 determines the gateway equipment which needs to send the downlink message according to a preset second hash algorithm; assuming that the determined gateway device is the gateway device 12, the gateway device 21 performs SDWAN tunnel encapsulation on the downlink packet and then sends the downlink packet to the gateway device 12, the gateway device 12 performs SDWAN tunnel decapsulation on the encapsulated downlink packet to obtain the downlink packet, and based on the downlink packet, establishes a fast forwarding table, sends the downlink packet to the gateway device 12, and the gateway device 12 sends the downlink packet to the user device 1.

Next, examples of the present application will be described in detail.
The embodiment of the present application provides a message processing method, which is applied to any gateway device in an SDWAN networking, and as shown in fig. 2, the method may include the following steps:
s21, when receiving the downlink message which is sent by any user equipment connected to the gateway equipment and needs to be sent to another user equipment in the SDWAN networking, acquiring the quintuple information of the downlink message.
In this step, the gateway device accessed by the user equipment is completely different from the plurality of gateway devices accessed by another user equipment.
Here, the number of gateway devices that the user equipment accesses may be one, or may be multiple, for example, 2.
In one example, the number of the plurality of gateway devices accessed by another user equipment may also be 2.
S22, in the local SDWAN table, the device information corresponding to the quintuple information is searched.
In this step, the device information is the device information of the gateway device that receives the uplink packet sent by another user device and needs to be sent to the user device.
For example, the device information may include identification information of a site to which the corresponding gateway device belongs, identification information of the corresponding gateway device, identification information of an interface connected to the gateway device on the corresponding gateway device, and the like.
S23, performing SDWAN tunnel encapsulation on the downlink message, sending the encapsulated downlink message to the gateway device corresponding to the device information, performing SDWAN tunnel decapsulation on the encapsulated downlink message by the gateway device corresponding to the device information to obtain a downlink message, and sending the downlink message to another user device.
Further, in the embodiment of the present application, the gateway device further performs the following operations:
when an encapsulated uplink message sent by gateway equipment corresponding to the equipment information is received for the first time, acquiring the equipment information from the encapsulated uplink message, and performing SDWAN tunnel decapsulation on the encapsulated uplink message to obtain an uplink message;
and adding quintuple information carried in the obtained uplink message and the obtained equipment information into a local SDWAN table.
It should be noted that the local SDWAN table at the gateway device side is created in advance, and may be empty initially, and once the gateway device receives the relevant encapsulated uplink packet sent by another gateway device for the first time, the gateway device obtains device information from the relevant encapsulated uplink packet, and performs SDWAN tunnel decapsulation on the relevant encapsulated uplink packet to obtain a relevant uplink packet; and then the gateway device adds the quintuple information carried in the obtained related uplink message and the obtained device information into a local SDWAN table, namely, the corresponding relation between the quintuple information and the device information is stored in the local SDWAN table, so that when the subsequent gateway device receives the corresponding downlink message, the corresponding downlink message can be subjected to SDWAN tunnel encapsulation and then returned to the other gateway devices in the original way based on the corresponding relation in the SDWAN table, and the table item resources and the hard disk resources of the gateway devices except the other gateway devices, which are accessed by the source user device of the related uplink message, cannot be occupied.
The following describes the above message processing method in detail with reference to specific embodiments.
Still taking the SDWAN networking shown in fig. 1 as an example, when the user equipment 1 needs to send the uplink packet 1 to the user equipment 2, the user equipment 1 determines, according to a preset hash algorithm, a gateway device that needs to send the uplink packet 1. Here, the predetermined hash Algorithm may be an MD5Message Digest Algorithm (MD5Message-Digest Algorithm, etc.).
It should be noted that, the specific determination process of the user equipment 1 determining the gateway device that needs to send the uplink packet 1 is the prior art, and is not described in detail herein.
Assuming that the determined gateway device is the gateway device 11, the user device 1 sends the uplink packet 1 to the gateway device 11.
After receiving the uplink packet 1, the gateway device 11 establishes a fast forwarding table entry based on the uplink packet 1, performs SDWAN tunnel encapsulation on the uplink packet 1, and then sends the uplink packet 1 to the gateway device 21. The encapsulated uplink packet 1 carries device information of the gateway device 11 (for example, includes identification information of a site to which the gateway device 11 belongs, identification information of the gateway device 11, identification information of an interface connected to the gateway device 21 on the gateway device 11, and the like).
Gateway device 21 receives encapsulated uplink packet 1 sent by gateway device 11 for the first time, acquires device information of gateway device 11 from encapsulated uplink packet 1, decapsulates the encapsulated uplink packet 1 to obtain uplink packet 1, adds quintuple information carried in the acquired uplink packet 1 and the acquired device information of gateway device 11 to a local SDWAN table, and sends uplink packet 1 to user device 2 for processing.
It should be noted that, for the gateway device 21, the gateway device 11 subsequently receives the relevant encapsulated uplink packet from the user equipment 1, directly performs SDWAN tunnel decapsulation on the relevant encapsulated uplink packet, and directly sends the decapsulated uplink packet to the user equipment 2 for processing.
When receiving a downlink message 2 sent by the user equipment 2 and needing to be sent to the user equipment 1, the subsequent gateway equipment 21 first obtains quintuple information of the downlink message 1; then, the gateway device 21 searches the device information corresponding to the quintuple information in a local SDWAN table; finally, the gateway device 21 performs SDWAN tunnel encapsulation on the downlink packet 1, and sends the encapsulated downlink packet 1 to the gateway device (i.e., the gateway device 11) corresponding to the found device information.
After receiving the encapsulated downlink message 1, the gateway device 11 decapsulates the SDWAN tunnel of the encapsulated downlink message 1 to obtain the downlink message 1, and sends the downlink message 1 to the user equipment 1.
It can be seen from the above technical solutions that, in the embodiment of the present application, for any gateway device in the SDWAN networking, when receiving a downlink packet sent by any user device accessing the gateway device and needing to be sent to another user device in the SDWAN networking, five-tuple information of the downlink packet is obtained first, where a gateway device accessed by the user device is completely different from a plurality of gateway devices accessed by another user device; then, searching device information corresponding to the quintuple information in a local SDWAN table, wherein the device information is the device information of gateway equipment which receives an uplink message which is sent by another user equipment and needs to be sent to the user equipment; and finally, performing SDWAN tunnel encapsulation on the downlink message, sending the encapsulated downlink message to the gateway equipment corresponding to the equipment information, performing SDWAN tunnel decapsulation on the encapsulated downlink message by the gateway equipment corresponding to the equipment information to obtain the downlink message, and sending the downlink message to another user equipment.
In the above message processing flow, it can be ensured that the transmission path of the uplink message sent by the user equipment to another user equipment is consistent with the transmission path of the downlink message sent by another user equipment to the user equipment, so that the table entry resources and the hard disk resources of the relevant gateway equipment can be saved.
