Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication networks struggle to reliably share physical layers among different networking protocols like GPON and Active Ethernet, leading to disruptions and errors due to the inability to automatically detect and configure the appropriate protocol for transmission.
Innovation Solution
A network device with a transceiver, clock/data recovery unit, and processing unit that senses signals at different rates to determine the appropriate networking protocol, enabling transmission in the correct mode without manual intervention, allowing for automatic detection and configuration of multiple access platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the physical layer is shared by multiple networking protocols (GPON and Active Ethernet), then device versatility and adaptability are improved, but transmission reliability deteriorates due to protocol conflicts and disruptions
Solution Approach 1:
The system performs preliminary detection of the networking protocol by sensing signals and determining synchronization data before enabling transmission. This preliminary action identifies whether the network uses GPON or Active Ethernet protocol, allowing the system to configure the appropriate transmission mode in advance and avoid protocol conflicts during operation
Solution Approach 2:
The system dynamically switches between different transmission modes based on the detected protocol. The transceiver can adaptively change its operating parameters and transmission characteristics to match the detected network protocol, enabling reliable operation across both GPON and Active Ethernet platforms without fixed configuration
2Reliability
If manual intervention is used to determine the networking protocol, then transmission reliability is maintained, but operational complexity and time consumption increase
Solution Approach 1:
The system performs self-identification of the networking protocol by automatically sensing signals and analyzing synchronization data. This self-service capability eliminates the need for manual protocol determination, allowing the system to autonomously configure the appropriate transmission mode without operator intervention while maintaining high accuracy
3Measurement precision
If signal sensing is performed at multiple rates to detect different protocols, then protocol detection accuracy is improved, but processing complexity and time consumption increase
Solution Approach 1:
The system senses signals at multiple predetermined rates (including first and second rates that may differ from the actual transmission rate) to cover various protocol possibilities. This partial sampling approach at key rates provides sufficient detection accuracy without requiring continuous analysis at all possible rates, balancing precision with processing complexity
