Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service providers face challenges in ensuring seamless and efficient failover of voice, video, and data transmissions due to limited visibility and control over complex networks involving multiple local exchange carriers and service providers, leading to sub-optimal performance and connectivity issues during primary circuit failures.
Innovation Solution
A data traffic management system that implements tunnels with continuous monitoring and remediation mechanisms, using technologies like GRE, IPsec, and routing protocols to detect failures and automatically switch traffic to alternate paths, ensuring uninterrupted service and minimizing performance impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If service providers use multiple LECs and service providers for circuit connectivity, then network coverage and connectivity are improved, but visibility and control over the circuit path deteriorate
Solution Approach 1:
The patent implements continuous monitoring of data traffic flow across multiple LECs and service providers, providing real-time feedback on circuit status and performance. This enables the system to detect failures and automatically adjust routing decisions, maintaining visibility and control despite the complexity of using multiple carriers.
Solution Approach 2:
The patent introduces an intermediary monitoring system that sits between the service provider and multiple LECs, consolidating visibility into a single point. This intermediary collects data from all carriers and presents unified circuit status information, simplifying the complex path through multiple LECs.
2Reliability
If automatic failover mechanisms are implemented, then service continuity is improved, but system complexity increases
Solution Approach 1:
The patent pre-configures alternate data traffic flow paths and establishes monitoring mechanisms before failures occur. When a primary circuit fails, the system has already identified viable alternatives and can switch traffic automatically without complex real-time decision-making, reducing the complexity of the failover mechanism.
Solution Approach 2:
The monitoring system automatically detects failures and triggers failover actions without requiring external intervention or complex control logic. The system monitors its own performance and self-corrects by switching to alternate paths, simplifying the overall failover system architecture.
3Loss of time
If continuous monitoring of data traffic flow is implemented, then failure detection speed is improved, but computational resources consumed increase
Solution Approach 1:
The patent implements monitoring at strategic points in the data traffic flow rather than examining every packet throughout the entire network. By placing monitors at key interfaces between LECs and service providers, the system achieves rapid failure detection with minimal computational overhead, avoiding the need to process excessive data.
Data Source
AI summary
A data traffic management system and method is described. Embodiments of the data traffic management system and method can include creating a plurality of tunnels in a communications network between a data center and a remote network. A failover solution of tearing down a tunnel when an issue is detected and immediately transferring data traffic to a second tunnel is provided. The plurality of data tunnels can be continuously monitored to ensure a viable data tunnel is available when a primary data tunnel fails.
