Data Unit Length Matching for Efficient Multi-Path Frame Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems using duplicate frames through multiple paths in relay networks increase network load due to the need for twice the bandwidth, and frame string transfer efficiency is reduced by padding processing when frame strings of varying lengths are padded to fixed lengths.
Innovation Solution
An information processing device and method that compares the lengths of consecutively received data unit strings and performs padding processing to equalize their lengths, ensuring efficient transfer without unnecessary padding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If duplicate frames are transmitted through multiple paths, then frame loss is reduced, but network load increases due to doubled bandwidth requirements
Solution Approach 1:
The patent merges multiple frame transmissions into a single encoded frame by performing XOR operations between duplicate frames from different paths. Instead of transmitting separate duplicate frames, the system combines them into one encoded frame that contains information from both original frames, thereby reducing network load while maintaining the reliability benefit of having multiple transmission paths.
2Ease of manufacture
If padding processing is performed on frame strings of variable lengths to equalize them, then encoding can proceed, but frame string transfer efficiency is reduced
Solution Approach 1:
The patent applies padding processing selectively and minimally - only to the extent necessary to equalize frame string lengths for encoding. Rather than padding all frame strings to a fixed maximum length, the system performs padding only on the shorter frame string just enough to match the longer one, thereby enabling encoding while minimizing efficiency loss.
3Device complexity
If frame strings are padded to fixed length, then encoding is simplified, but data unit string transfer efficiency is reduced due to unnecessary padding
Solution Approach 1:
The patent implements a dynamic padding approach where the padding length is determined by the actual length difference between frame strings rather than using a fixed maximum length. The system dynamically adjusts the padding amount based on the specific frames being encoded, allowing encoding simplicity to be maintained while avoiding the efficiency loss of fixed-length padding.
