Gigabit Zero-Delay Tap for Ethernet Power Disruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-speed Ethernet environments, power disruptions cause communication links to be renegotiated, leading to latency and potential financial losses due to bidirectional and unpredictable data traffic directions, which existing technologies struggle to mitigate effectively.
Innovation Solution
A gigabit-zero delay tap system with a primary and alternative power source, monitored by a sensor controller that activates the alternative power source and uses capacitors to maintain communication links, minimizing latency and data packet loss during power disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an inline tap arrangement is employed in gigabit Ethernet environment, then bidirectional data traffic can be monitored, but power disruption causes communication link renegotiation leading to latency
Solution Approach 1:
The patent applies preliminary action by pre-configuring alternative power paths and maintaining backup power sources that can be activated before complete power failure occurs. The system prepares alternative communication paths in advance so that when primary power is lost, the transition to backup power and alternative paths occurs with minimal disruption to data traffic flow.
Solution Approach 2:
The patent implements beforehand cushioning by introducing backup power sources and alternative power paths that act as a cushion against primary power failure. These backup mechanisms are designed to absorb the impact of power disruption, preventing complete link failure and reducing latency by providing a buffered transition period during which monitoring continues uninterrupted.
2Speed
If auto-negotiation is performed to establish communication link, then fastest transmission mode is determined, but power disruption causes link loss and renegotiation time
Solution Approach 1:
The patent applies preliminary action by pre-establishing alternative communication paths and maintaining power path information in memory. When power disruption occurs, the system can immediately switch to backup paths without needing to perform complete auto-negotiation again, significantly reducing link establishment time while maintaining optimal transmission speeds.
Solution Approach 2:
The patent uses copying by creating backup copies of power paths and communication routes. These copied paths are identical to the primary paths but serve as failovers when power disruption occurs. The backup paths are pre-configured with the same transmission parameters, allowing immediate activation without re-negotiation.
3Ease of manufacture
If network tap is taken offline for maintenance, then power can be disconnected, but communication path must be renegotiated causing delay
Solution Approach 1:
The patent applies preliminary action by pre-configuring alternative power paths and maintaining backup power sources that can be activated before complete power failure occurs. The system prepares alternative communication paths in advance so that when primary power is lost, the transition to backup power and alternative paths occurs with minimal disruption to data traffic flow.
Solution Approach 2:
The patent introduces intermediary backup power paths that act as mediators between the primary power source and the network tap. These intermediary paths allow power disruption to be managed gracefully by providing a transition route that maintains communication functionality during and after maintenance operations.
