Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The heavy workload of DetNet service configuration in deterministic networking, caused by poor performance of the controller, leads to inefficiencies in configuring high-reliability services in large-scale networks.
Innovation Solution
A routing information processing method and system that utilizes a BGP notification node to acquire and add redundancy protection attributes to BGP routing information, enabling automatic creation or selection of redundancy-protected routing paths, and reducing the configuration workload by performing diversion processing based on redundancy protection information, color information, and end node information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If centralized control mode is used for DetNet service configuration, then service configuration can be managed centrally, but heavy workload is caused due to poor controller performance
Solution Approach 1:
The patent extracts the service configuration function from the centralized controller and relocates it to edge network devices. Specifically, the controller generates only the service configuration policy, while the edge devices automatically generate detailed service configuration information and routing information, thereby removing the heavy configuration workload from the controller.
Solution Approach 2:
Edge network devices perform self-service by automatically generating service configuration information and routing information based on policies received from the controller. This eliminates the need for the controller to manually configure each service detail, reducing its workload while maintaining centralized policy control.
2Reliability
If manual configuration of redundancy protection is performed, then routing paths can be protected, but configuration workload increases significantly
Solution Approach 1:
The BGP notification node automatically performs self-service by autonomously generating redundancy protection routing information based on its own redundancy protection capability. This eliminates manual configuration efforts while ensuring reliable redundancy protection through automated path selection and attribute addition.
Solution Approach 2:
The system changes the parameter of routing information by adding specific attributes that indicate redundancy protection capability. The BGP notification node modifies routing information parameters to include redundancy attributes, enabling automatic identification and selection of protected paths without manual intervention.
3Productivity
If BGP routing information with redundancy attributes is automatically generated, then configuration workload is reduced, but complexity of routing information processing increases
Solution Approach 1:
The patent uses existing BGP routing information structures and extends them with redundancy attributes rather than creating entirely new complex structures. The added attributes serve multiple functions: indicating redundancy capability, enabling path selection, and facilitating automatic configuration, thereby managing complexity while providing versatile functionality.

AI summary
The implementation manners of the present application relate to the technical field of data processing, and in particular, to a routing information processing method and system, and a network device and a storage medium. The routing information processing method comprises: acquiring a redundancy protection capability of a BGP notification node; on the basis of a preset attribute adding policy and according to the redundancy protection capability, adding a first attribute to first BGP routing information of the BGP notification node, so as to generate BGP routing information, wherein the first attribute contains redundancy protection information, and the BGP routing information contains color information and end node information; and sending the BGP routing information to a BGP receiving node, which communicates with the BGP notification node, such that the BGP receiving node performs diversion processing on the BGP routing information according to the redundancy protection information, the color information and the end node information.
