Multichannel Superframe Header Merging for Higher Data Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission standards in passive optical networks result in low data efficiency when information is distributed across multiple channels due to the addition of frame headers on each channel, leading to reduced efficiency as the number of channels increases.
Innovation Solution
A multichannel data transmitting method where a single frame header data unit indicates the channels and initial transmitting positions for all data units, eliminating redundant headers on individual channels, thereby improving data efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is distributed on multiple channels to improve channel capacity and peak rate, then transmission throughput is improved, but data efficiency deteriorates due to frame header overhead on each channel
Solution Approach 1:
The patent merges the frame header functionality across multiple channels by placing a single frame header on only one channel (the first channel) while other channels transmit only pure data units. This eliminates redundant header overhead on subsequent channels, directly resolving the contradiction by maintaining multi-channel throughput while improving data efficiency through header consolidation.
Solution Approach 2:
The frame header on the first channel serves a universal function for all channels by containing channel identification information and initial position indicators that enable the receiver to correctly assemble data units from multiple channels. This multi-functional header replaces the need for separate headers on each channel, improving efficiency while maintaining the ability to handle multi-channel data distribution.
2Adaptability or versatility
If frame headers are added on each channel to enable independent data transmission, then channel independence is improved, but overhead increases and data efficiency decreases
Solution Approach 1:
The patent extracts the frame header from all channels except the first one, removing redundant header overhead while preserving channel independence. The header functionality is concentrated on the first channel, which contains sufficient information (channel IDs and initial positions) to enable the receiver to independently process and assemble data from all channels without requiring separate headers on each channel.
3Productivity
If the number of channels is increased to improve transmission capacity, then peak rate is improved, but data efficiency deteriorates due to cumulative header overhead
Solution Approach 1:
The patent merges all frame header functions into a single location on the first channel, eliminating the cumulative header overhead that would otherwise increase with each additional channel. This allows the system to scale to more channels for higher peak rates without suffering from proportionally increasing overhead, thus maintaining data efficiency while improving productivity.
