Last Resource Disaster Routing in Telecommunications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecommunication networks face challenges in ensuring continuous communication during large-scale outages, where both primary and redundant paths may be affected, leading to disruptions in critical communications such as emergency services.
Innovation Solution
Implementing a last resource disaster recovery mechanism that identifies failed routes and automatically routes communications to a secondary telecommunications network, ensuring connectivity to the intended destination through a dedicated disaster recovery network device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant transmission paths are provided for disaster recovery, then communication reliability is improved during network outages, but both primary and redundant paths may be affected by large-scale outages, causing transmission to cease
Solution Approach 1:
The patent introduces a disaster recovery network device as an intermediary component that bridges the first telecommunications network and a second telecommunications network. When the primary network experiences large-scale outages affecting both primary and redundant paths, this intermediary device automatically intercepts communications and reroutes them through the second network, ensuring continuous transmission without requiring complex multi-path routing within the affected network
Solution Approach 2:
The patent transitions from two-dimensional routing (primary and redundant paths within the same network) to three-dimensional routing by adding a temporal and external dimension. The disaster recovery device monitors network status in real-time and dynamically switches to an external second telecommunications network when internal redundancy fails, creating a vertical escape path from the affected network layer to an external operational network layer
2Reliability
If automatic disaster recovery routing is implemented, then communication continuity is improved during outages, but the system requires automatic detection and routing capabilities that increase device complexity
Solution Approach 1:
The disaster recovery network device is configured with automatic detection and routing capabilities that enable it to self-manage the disaster recovery process. The device autonomously monitors the status of the first telecommunications network, detects outages without external intervention, and automatically switches communications to the second network based on pre-configured criteria, eliminating the need for manual intervention or complex centralized control systems
Solution Approach 2:
The system performs preliminary configuration of the disaster recovery network device with routing rules and network parameters before outages occur. The device is pre-provisioned with knowledge of the second telecommunications network and automatic routing logic, enabling it to immediately activate disaster recovery routing when outages are detected, rather than requiring complex real-time decision-making or reconfiguration during the emergency

AI summary
Aspects of the present disclosure involve systems, methods, computer program products, and the like, for providing disaster routing of particular communications through a telecommunications network during a network outage. The disaster routing may ensure that communications from a particular source or to a particular destination are connected to the destination even during times when portions of the network may be inoperable. In one particular embodiment, the disaster routing may be performed for emergency communications received at the network and connected to one or more emergency services configured to receive the emergency communication. However, the disaster routing mechanisms and techniques described herein may be applied or available to any type of communication from any source or customer to the telecommunications network.
