Layer-Aware File Distribution for Lower VNF Network Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of virtual network functions (VNFs) in mid-scale or small-scale facilities leads to increased network load due to the transmission of redundant file layers, affecting communication speed and traffic between large-scale and small-scale facilities.
Innovation Solution
A file distribution system that transmits only non-redundant layers by comparing layer information of files to be distributed, using a file distribution apparatus and reception apparatus to manage and control the transmission of layers, and optionally rewriting source codes for layer commonization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If files are transmitted from large-scale facilities to mid-scale or small-scale facilities for VNF deployment, then deployment capability is improved, but network load increases and communication speed decreases
Solution Approach 1:
The patent segments files into multiple layers and identifies common layers across different files. By transmitting only non-common layers individually while reusing common layers, the system reduces redundant data transmission and network load while maintaining complete file deployment capability at mid-scale and small-scale facilities.
2Reliability
If all layers of multiple files are transmitted to ensure complete deployment, then deployment completeness is improved, but communication traffic increases
Solution Approach 1:
The patent merges common layers from multiple files into a shared resource that can be reused across different file deployments. By combining the common layer transmission with individual non-common layer transmissions, the system ensures complete deployment while minimizing total communication traffic through layer reuse.

AI summary
A file distribution system provided with a file distribution apparatus and a file reception apparatus, wherein: the file distribution apparatus has one or more first processors; and the one or more first processors execute a process including transmitting, to the file reception apparatus, multiple layers included in a first file to be distributed to the file reception apparatus, and among multiple layers included in a second file to be distributed to the file reception apparatus, a layer other than a common layer that is included in common in the first file and the second file.
