Network Restoration Mechanism Using GET POST Commands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network restoration mechanisms are topology-specific, making it difficult to implement a unified solution for fault restoration across different network topologies such as star, ring, and tree topologies, especially in high-level environments like VLAN, MAC, IP, and QoS.
Innovation Solution
A method and system that identifies membership within an existing tree network, uses GET and POST commands to gather information from neighboring nodes for updating node configurations, and applies blockages at ports to restore fault links while avoiding loops, ensuring network connectivity and optimal data traffic conditions across any topology.

Engineering Contradiction Analysis
1Adaptability or versatility
If topology-specific restoration mechanisms (STP, RSTP, ERPS) are used for different network topologies, then fault restoration can be achieved for each specific topology, but it becomes difficult to implement a unified restoration solution across different network topologies
Solution Approach 1:
The patent applies universality by creating a single restoration mechanism that can operate across multiple network topologies (tree, ring, star, mesh) without requiring topology-specific protocols. The mechanism uses generic operations (identify fault, gather neighbor information, update node configuration, apply blockages) that are applicable regardless of the underlying topology, thereby achieving multi-functionality and eliminating the need for separate STP, RSTP, or ERPS protocols.
2Device complexity
If a single restoration mechanism is implemented across all network topologies, then unified fault restoration is achieved, but it may be difficult to handle topology-specific restoration requirements
Solution Approach 1:
The patent applies segmentation by dividing the restoration process into distinct operational stages: identifying membership with an existing tree, detecting fault occurrence, gathering information from neighboring nodes, updating node configuration, and applying blockages at ports. This segmented approach allows the single mechanism to handle topology-specific requirements through standardized operations that can be applied uniformly while adapting to different topology characteristics.
3Reliability
If blockages are applied at ports to restore fault links and avoid loops, then network connectivity is maintained, but it may affect data traffic flow
Solution Approach 1:
The patent applies local quality by applying blockages selectively at specific ports rather than globally across the entire network. The mechanism identifies the precise location of faults and applies blockages only at the affected ports to prevent loops, while leaving other ports and paths operational. This localized approach maintains network connectivity and prevents loops without unnecessarily disrupting data traffic flow through unaffected portions of the network.

Embodiments of the present invention described herein, discloses a method and system for managing a communication network using any loop avoidance or mitigation technology. The restoration of network under fault, or sub-optimal network condition, maintenance and improvement of network connectivity and network behaviour is based upon GET and POST commands. In one embodiment of the present invention, the restoration mechanism is used to maintain or improve network connectivity and network behaviour or function upon receipt of command from management plane or control plane to build optimal network condition (e.g: minimum hops, maximum bandwidth, etc.) for data traffic, within a communication network of any topology.
