Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network technologies experience service disruptions during the interruption and reestablishment of peer relationships between routing devices due to the deletion of routing entries, leading to service damage.
Innovation Solution
A method and apparatus that prevent the deletion of routing entries during the interruption of peer relationships, allowing continued service processing and ensuring the accuracy of routing entries by managing differential entries upon reestablishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If routing entries are deleted when peer relationship is interrupted, then memory resources are released, but service continuity is damaged
Solution Approach 1:
The patent segments routing entries into two categories: valid routing entries and invalid routing entries. Valid routing entries are those that are currently being used for service, while invalid routing entries are those that are no longer needed. This segmentation allows the system to selectively delete only invalid routing entries while preserving valid ones, thus maintaining service continuity while still freeing up memory resources.
Solution Approach 2:
The patent implements a preliminary action by establishing a correspondence relationship between routing entries and peer relationships before the peer relationship is actually interrupted. When a peer relationship is interrupted, the system can quickly identify and mark the corresponding routing entries as invalid without needing to search through all routing entries, enabling fast and accurate cleanup while preserving service continuity.
2Reliability
If routing entries are not deleted during peer relationship interruption, then service continuity is maintained, but routing entry accuracy deteriorates
Solution Approach 1:
The patent segments routing entries into valid and invalid categories, allowing the system to maintain all routing entries in memory for service continuity while clearly marking invalid ones. This segmentation enables the system to preserve service continuity without compromising routing entry accuracy, as invalid entries are identified and excluded from active routing operations.
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors peer relationship status and updates the validity status of corresponding routing entries. When a peer relationship is interrupted, the system provides feedback by marking the associated routing entries as invalid, ensuring that routing entry accuracy is maintained while service continuity is preserved through the selective validity marking approach.
3Manufacturing precision
If routing entries are deleted upon peer relationship interruption, then outdated routing information is removed, but service processing is interrupted
Solution Approach 1:
The patent segments routing entries into valid and invalid categories, allowing the system to remove outdated routing information (invalid entries) while preserving service processing continuity (valid entries). This segmentation enables selective deletion of only those routing entries that are actually outdated, rather than deleting all routing entries associated with an interrupted peer relationship.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a validity flag or marker that mediates between the need to remove outdated routing information and the need to maintain service processing continuity. This intermediary allows the system to distinguish between routing entries that should be removed and those that should be preserved, enabling smooth transition without service interruption.

AI summary
This application provides a peer relationship management method and apparatus, a device, and a storage medium, and belongs to the field of network technologies. In this application, when a peer relationship between a first routing device and a second routing device is interrupted, routing entries received from the second routing device are not deleted. Services may be still processed, within a time range from a time at which the peer relationship is interrupted to a time at which the peer relationship is reestablished, by using the routing entries received from the second routing device. This avoids impact on the services related to the routing entries after the routing entries are deleted.
