Problems solved by technology

[0004] At present, in the process of establishing the Overlay network, the deployment of the branch device and the center device uses the MSTP link. The service traffic between the branch device and the center device can be reached through the direct link or through the backup When the link arrives, the link cannot be solidified after the packet enters the Overlay tunnel, which is not conducive to accurate scheduling of service traffic on the link

Embodiment Construction

[0028] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0029] see figure 1 , the embodiment of the present application provides a communication system, the system includes a central end device and a branch device communicatively connected to the central end device.figure 1 The illustrated center devices include HUB-1 and HUB-2, and the branch devices include Spoke-1, Spoke-2, Spoke-3, and Spoke-4. figure 1 The shown numbers of central end devices and branch devices are only examples, and are not intended to be limitations of the present application.

[0030] Assuming that according to the existing tunnel establishment method, HUB-1 can establish a tunnel with Spoke-1, Spoke-2, and HUB-2 respectively (links can be formed through the tunnel), such as establishing a tunnel between HUB-1 and Spoke-1 A tunnel, a tunnel is established between HUB-1 and Spoke...

Abstract

The invention provides a tunnel adaptive configuration method and device, center end equipment and a communication system. The method comprises the following steps: receiving a next hop parsing protocol (NHRP) message for requesting to establish a tunnel from a local interface; judging whether the local interface is a legal interface for establishing a tunnel or not; when the local interface is a legal interface, determining a first public network address for establishing a tunnel with the target equipment based on the NHRP message; wherein the first public network address is a public network IP address of the central end device, and the target device is a device sending the NHRP message. By means of the mode, the controllability of tunnel establishment can be enhanced, some backup links are effectively removed, the links and the tunnels have the unique corresponding relation, and therefore accurate scheduling of service flow on the links is facilitated.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular, relates to a tunnel self-adaptive configuration method and device, central end equipment and a communication system. Background technique [0002] SD-WAN (Software Defined Wide Area Network) is a service formed by applying SDN (Software Defined Network) technology to WAN scenarios. This service is used to connect corporate networks, data centers, Internet applications and cloud services across a wide geographic area. [0003] To realize the SD-WAN solution, it is necessary to build an Overlay (overlay) network to form an Underlay (bottom layer) network and an Overlay two-layer network. The Overlay network is constructed using tunnel technology. The commonly used tunnel technology is IPsec VPN (Internet Protocol Security Virtual Private Network, based on the Internet Security protocol virtual private network technology), GRE (Generic Routing Encapsulation, gener...
