NAS Protocol Fingerprint Matching for Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional NAS protocols place high bandwidth demands on computer networks during file transfers, leading to degraded performance and unsatisfactory user experiences, and existing efficiency-enhancing software can be complex and inconvenient to manage.
Innovation Solution
The technique leverages a standard NAS protocol to augment its file-copying ability with fingerprint matching, limiting network data copying to unique data segments by identifying and avoiding redundant segments through fingerprint comparison between source and destination computers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional NAS protocol is used for file transfer, then file copying functionality is provided, but network bandwidth demand becomes excessively high
Solution Approach 1:
The system performs preliminary fingerprint analysis of data segments before initiating full file transfer. The source computer generates fingerprints of its data segments and sends them to the destination computer, which compares these fingerprints against its existing data segments. This preliminary action identifies redundant data that can be skipped, preventing unnecessary network bandwidth consumption while maintaining complete file copying functionality.
2Quantity of substance
If fingerprint matching software is used to improve copying efficiency, then network bandwidth consumption is reduced, but system complexity increases
Solution Approach 1:
The patent merges the fingerprint matching functionality directly into the NAS protocol itself. Rather than using separate fingerprint analysis software that runs independently, the fingerprint generation, transmission, and comparison operations are integrated as native functions within the NAS protocol stack. This combining of functions eliminates the need for users to manage separate software components, reducing operational complexity while maintaining bandwidth efficiency.
3Productivity
If custom protocol is implemented for fingerprint matching, then data transfer efficiency is improved, but compatibility and maintenance challenges arise
Solution Approach 1:
The patent implements fingerprint matching using standard NAS protocol operations that are universally supported across different NAS implementations. The fingerprint data is transmitted and processed using existing NAS protocol mechanisms rather than requiring a custom protocol layer. This approach maintains broad compatibility with various NAS systems and storage devices while still achieving improved data transfer efficiency through intelligent fingerprint-based redundancy detection.
