Optical Network Frame Grouping for Bandwidth Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In passive optical networks, the existing G-PON/XG-PON Encapsulation Method (GEM/XGEM) frames result in low bandwidth utilization due to large frame headers and small payload proportions, especially when transmitting short data frames.
Innovation Solution
The method involves converting a single data frame into a data frame group, encapsulating the group with a single frame header, and transmitting the encapsulated frame, thereby reducing the proportion of the frame header and increasing the payload proportion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one data frame is mapped into one GEM/XGEM frame for transmission, then the data frame can be transmitted with proper encapsulation, but the frame header accounts for a relatively large proportion and bandwidth utilization is relatively low
Solution Approach 1:
The patent combines multiple data frames into a single data frame group, which is then encapsulated into one GEM/XGEM frame. This merging approach reduces the number of frame headers needed, as one header now serves multiple data frames, thereby improving bandwidth utilization while maintaining transmission reliability through proper group encapsulation
Solution Approach 2:
The frame header in the encapsulated data frame group serves a universal function by identifying and managing multiple data frames within a single group. This multi-functionality allows the header to provide control information for the entire group rather than individual frames, reducing overhead and improving efficiency
2Productivity
If multi-channel bonding is used, then data transmission capacity is increased, but the frame header is inserted to each channel and bandwidth utilization becomes even more serious
Solution Approach 1:
In multi-channel bonding scenarios, the patent applies the same grouping principle where data frames are consolidated into groups before being distributed across multiple channels. This reduces the total number of frame headers that need to be inserted across all channels, thereby maintaining high transmission capacity while reducing the cumulative header overhead complexity
