Abstract

The embodiment of the invention discloses a tunnel keep-alive method, network equipment, a system and a storage medium, and belongs to the technical field of communication. In the embodiment of the invention, before the communication between the UP equipment and the CP equipment fails, the UP equipment receives the tunnel information synchronized by the CP equipment, and after the communication between the UP equipment and the CP equipment fails, the UP equipment performs tunnel keep-alive according to the tunnel information, namely, the UP equipment maintains the tunnel between the UP equipment and the remote network equipment. In this way, it is avoided that tunnel dismantling is triggered due to communication faults between the CP device and the UP device, it can be guaranteed that network connection between the terminal and the remote end is not interrupted, and it is also guaranteed that user services are not damaged.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communications, and in particular to a tunnel keep-alive method, network equipment, system, and storage medium. Background technique [0002] Currently, a terminal can access a network through a broadband network gateway (broadband network gateway, BNG) device deployed in the network. Traditional BNG devices are coupled with control plane (control plane, CP) functions and user plane (user plane, UP) functions. With the development of communication technology, the industry proposes a BNG that separates control plane functions and user plane functions. The BNG is called a virtual broadband network gateway (virtual broadband network gateway, vBNG), and includes a CP device and a UP device. When the Layer 2 Tunnel Protocol access concentrator ((layer 2tunnel protocol, L2TP) access concentrator, LAC) is implemented through vBNG, the CP device can establish a connection between the ...
