Problems solved by technology

In this case, since the mGRE interface will be randomly selected when multiple mGRE interfaces are established on the client terminal equipment, it is possible to establish a tunnel between the Internet of two different operators, resulting in a decrease in network transmission efficiency
In addition, this solution also has the problem that there are many tunnels that need to be maintained between client terminal devices, which increases the burden of link detection and occupies a certain amount of network transmission bandwidth.

Embodiment 1

[0038] According to an embodiment of the present invention, the method further includes: using the extended next hop resolution protocol to receive a next hop resolution protocol request message containing an extension field, wherein the extension field carries operator network information; Extract the operator's network information; return the next hop information that matches the operator's network information.

[0039] In this embodiment, it should be noted that the next hop analysis protocol used when parsing the next hop analysis protocol request message or the next hop analysis protocol of the exhibition needs to use the same protocol as the client terminal device that sends the message request, so , the carrier network information carried in the extension field can be accurately extracted. Similarly, the matching here should preferably be the same. When there is no identical network interface, a network interface with better network interconnectivity can also be returne...

Embodiment 1

[0042] According to an implementation manner of an embodiment of the present invention, the method further includes: storing the operator network information in the attribute of the network interface.

[0043] In this embodiment, it is only necessary to obtain the network information of the operator once, and store the information in the properties of the network interface. In this way, it is not necessary to query the network address when needed later, but only needs to read the properties of the network interface The network information of the network operator connected to the network interface can be obtained.

Embodiment 1

[0044] According to an embodiment of the present invention, the method further includes: sending a next-hop resolution protocol request message to a central site (Hub) to request next-hop information, and forwarding to other client terminal devices via the central site.

Abstract

The invention discloses a method, device and system for establishing a network tunnel and a storage medium. The method comprises the following steps: when a dynamic tunnel is established between client terminal devices of a software-defined wide area network branch mechanism, firstly, acquiring operator network information connected with a network interface; then, using the expanded next-hop resolution protocol NHRP for generating a next-hop resolution protocol request message containing an expansion field, wherein the expansion field carries operator network information; then, sending a next-hop analysis protocol request message to request next-hop information; then, receiving next hop information which is returned by other network equipment and matched with the operator network information; next, establishing a network tunnel according to the next hop information. Therefore, the mGRE tunnel can be established by optimizing the network with the same operator through the operations, and therefore the communication quality and the transmission efficiency are greatly improved.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method, device, system and storage medium for establishing a network tunnel. Background technique [0002] Software-Defined Wide Area Network (Software-Defined WAN, SDWAN) is a service formed by applying software-defined network (SDN) technology to wide area network scenarios. and cloud services. In SDWAN networking, a central site plus multiple Customer Premise Equipment (CPE) architecture is generally adopted. The central site is generally deployed in the corporate headquarters, while the customer premise equipment is deployed in the branch offices of the enterprise. A dynamic tunnel will be established between client terminal devices to communicate with each other. Multipoint Generic Routing Encapsulation (mGRE) is a common technology for establishing dynamic tunnels between client terminal devices. A dynamic tunnel can be established between mGRE interfaces on multiple ...
