Node Equipment Consistency Check for Service Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-layer networks, resource inconsistency due to node equipment abnormalities leads to unreliable service transmission, especially in complex wide area networks with critical real-time requirements, where existing methods like cold backup result in service interruptions and rebuilding.
Innovation Solution
A method for ensuring end-to-end Quality of Service reliability by performing consistency checks within and between node equipment to identify and release inconsistent connection information, thereby maintaining network serviceability and preventing resource hang-ups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cold backup method is used to guarantee service reliability, then service reliability is improved, but service interruption and rebuilding occur in complex wide area networks
Solution Approach 1:
The patent performs consistency checks on connection information before service failures occur. The system proactively verifies whether connection information stored in different modules and nodes is consistent, and releases inconsistent information in advance. This preliminary action prevents resource hang-ups and service interruptions that would otherwise occur during actual service delivery, thereby resolving the contradiction between reliability and service interruption time.
2Adaptability or versatility
If resource allocation is performed in multi-layer networks, then network serviceability is improved, but resource inconsistency occurs due to node equipment abnormalities
Solution Approach 1:
The patent implements a feedback mechanism where node equipment continuously monitors and checks the consistency of connection information. When inconsistencies are detected due to node abnormalities, the system releases the inconsistent connection information and notifies relevant nodes to update their records. This feedback loop ensures resource consistency is maintained across the multi-layer network while preserving serviceability.
3Ease of operation
If connection information is maintained in all node equipment for session connection, then service routing capability is improved, but information inconsistency leads to resource hang-ups
Solution Approach 1:
The system performs consistency checks on connection information stored in node equipment before these inconsistencies cause resource allocation failures. By proactively detecting and releasing inconsistent connection information, the system maintains both the routing capability benefits of distributed information storage and the reliability of resource allocation.
Solution Approach 2:
The patent establishes a feedback mechanism where nodes verify the consistency of their stored connection information against other nodes. When inconsistencies are detected, the system releases the problematic information and notifies relevant nodes to synchronize their records. This feedback ensures that while all nodes maintain routing information for ease of operation, resource allocation reliability is preserved through continuous consistency verification.

AI summary
A method for guaranteeing service reliability in an end-to-end Quality of Service framework is provided. The method includes checking whether connection information held in all node equipment gone through by a session connection is consistent. If the connection information is consistent, the consistency check is completed. Otherwise, the inconsistent connection information is released from the node equipment. In the provided method, a consistency check is performed inside every node equipment, and between node equipment in the network, and thus, abnormal resources may be retrieved, so that network service ability will not be affected by abnormal situations. Consistent with the provided method, degradation of service ability because of network abnormity can be avoided, and network reliability and availability can be improved.
