Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing and managing end-to-end network connections within complex networks can be time-consuming due to the need to reconfigure various data routes and cross-connections, especially in the event of network failures.
Innovation Solution
A method and system that utilize pre-stored nodal maps on network elements, where a network controller identifies failures and selects appropriate nodal maps to trigger activation requests, reconfiguring cross-connections efficiently without individually reconfiguring links and nodes.

1Reliability
If traditional routing table methods are used to manage network connections, then network connectivity can be established, but the time required to implement and adjust data routes increases significantly during network failures
Solution Approach 1:
The patent pre-calculates and stores multiple nodal maps in the network elements before failures occur. Each nodal map contains pre-determined routing information for alternative paths. When a failure is detected, the system simply activates a pre-computed nodal map rather than calculating new routes in real-time, dramatically reducing recovery time while maintaining network connectivity
Solution Approach 2:
The system dynamically switches between different nodal maps based on network conditions. Multiple nodal maps are maintained with different routing configurations, and the active map is changed in response to detected failures. This dynamic switching capability allows the network to adapt to various failure scenarios without manual reconfiguration
2Adaptability or versatility
If individual links and nodes are reconfigured manually to establish alternative routes, then network paths can be adjusted, but the complexity and resources required for management increase
Solution Approach 1:
The patent combines multiple individual routing decisions into a single nodal map structure. Instead of managing numerous individual link and node configurations, the system uses unified nodal maps that encapsulate complete alternative path information. This merging simplifies management while maintaining the ability to implement complex alternative routes across multiple network elements
Solution Approach 2:
The system segments the network management function into separate nodal maps, each representing a complete alternative routing configuration. This segmentation allows the complex task of alternative route management to be divided into discrete, pre-computed units that can be independently stored and activated, reducing the operational complexity of managing network adaptability

AI summary
A method for managing network connections may include identifying a network failure within a network comprising various network elements. The method may include selecting, in response to identifying the network failure and for the network elements, a subset of nodal maps from various nodal maps. The nodal maps may be stored on the network elements. The subset of nodal maps may describe various cross-connections of the nodal maps within a first end-to-end connection in the network. The method may include transmitting, in response to selecting the subset of nodal maps, various activation requests to trigger the network elements to implement the subset of nodal maps.
