Service protection method and device based on SPN, equipment and storage medium

Abstract

The invention discloses a service protection method and device based on an SPN, equipment and a storage medium. The method comprises the following steps: allocating two IP addresses to a base station carried by an SPN access loop; deploying two sets of three-layer virtual private network services in an SPN, and respectively configuring two routes of two different physical paths to a core network for the two sets of three-layer virtual private network services; and completing access of two IP addresses to the two sets of three-layer virtual private network services in the SPN to form a logic biplane from the two IP addresses to the core network. It can be seen that according to the scheme of the invention, a base station adopts a dual-service IP through configuration and points to different transmission sub-interfaces, so that a logical dual-plane channel is formed on the same SPN, and services can have a service layer protection function.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a service protection method, device, equipment and storage medium based on an SPN network. Background technique [0002] The existing service protection of wireless base stations (including 5G base stations and 4G base stations) carried by the SPN (Slicing Packet Network) L3 to the edge is realized based on the protection of the carried SPN network. The business of each base station adopts a single service IP, and the route of the base station points to a single gateway, that is, the port IP address connected to the SPN port. Then it is forwarded to the NPE node (edge ​​node on the network side) through the L3VPN to reach the core network. [0003] Service protection is implemented through active / standby switchover, that is, it runs on a single plane. Specific protection schemes include device-level protection and network-level protection. Device-level protec...

Problems solved by technology

[0004] The existing technical solutions rely on the bearer network itself to perform protection switching, and realize the device-level and network-level fault protection of the bearer network. However, when the bearer network is abnormal and cannot realize self-switching, services will be blocked

figure 1 A schematic diagram showing a specific abnormal condition of the bearer network in the SPN network, as shown in figure 1 As shown, when the active SPE node (that is, the node marked with a cross in the figure) has a device abnormality, OAM (Operation Administration and Maintenance, operation, maintenance and management) detection is not triggered due to the problem of the device forwarding plane, resulting in the downlink access ring The base stations on the road cannot perceive the forwarding problem, which leads to the uplink failure of the base station
