Multichannel Data Transmission Using Shared Frame Headers
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, and a corresponding receiving method to assemble the data correctly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is distributed on multiple channels according to existing transmission standard, then channel capacity and peak rate are improved, but data efficiency deteriorates due to addition of frame headers on each channel
Solution Approach 1:
The patent merges the frame header functions into a single shared header structure that is common to all channels. Instead of having separate frame headers on each channel, one frame header contains information (such as channel identifiers and initial transmitting positions) that enables the receiver to correctly assemble data from multiple channels, thereby eliminating redundant headers and improving data efficiency while maintaining multichannel capacity
Solution Approach 2:
The frame header is designed with universal functionality that serves all channels simultaneously. The header contains generalized information (channel identifiers, initial transmitting positions) that enables it to control and coordinate data transmission across multiple channels, making a single header structure applicable to any number of channels rather than requiring channel-specific headers
2Adaptability or versatility
If frame header is added on each channel for data transmission, then data can be transmitted on multiple channels, but data efficiency is reduced due to redundant headers
Solution Approach 1:
Multiple channel control functions are merged into a single frame header structure. The header contains channel identifier information and initial transmitting position information that enables coordination of multiple channels, replacing what would otherwise require separate headers on each channel and eliminating redundancy
Solution Approach 2:
The patent extracts the channel-specific identification information from individual channel headers and consolidates it into a single shared frame header. By taking out only the essential channel identifiers and position information needed for multichannel coordination, the system maintains adaptability while removing redundant header data
