Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional file transfer methods over networks like the Internet and WANs are inefficient and impractical for transmitting large files, such as high-resolution audio-video files, due to significant network impact and resource requirements, especially during peak traffic periods.
Innovation Solution
An adaptive file delivery system that breaks down large files into segments and transmits them during periods of minimum network activity, adjusting transfer rates to maintain delivery deadlines and reduce network impact, using a sending system and receiving system connected via various network types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large files are transmitted using conventional file transfer methods, then file transfer service is provided, but network impact becomes significant and resource requirements increase
Solution Approach 1:
The patent divides large files into smaller segments or blocks before transmission. Each segment is independently managed and transmitted, allowing the system to control network impact while maintaining overall transfer efficiency. This segmentation enables parallel transmission and better utilization of network resources during off-peak periods.
Solution Approach 2:
The system transmits file segments during periodic off-peak network hours when network traffic is minimal. By scheduling transmissions during these specific time windows, the patent reduces network impact while still achieving timely delivery of large files. The transmission process is paused during peak hours and resumed when network conditions improve.
2Productivity
If network transmission capacity is expanded to meet peak traffic demands, then file transfer capability is improved, but resource expenditure and costs increase significantly
Solution Approach 1:
The patent implements dynamic transmission rate adjustment based on real-time network conditions. The system monitors network traffic patterns and adapts transmission speed accordingly, using higher rates during off-peak periods and lower rates or pausing during peak periods. This dynamic approach eliminates the need for permanent capacity expansion while maintaining effective file transfer capability.
Solution Approach 2:
The system changes transmission parameters such as data rate, packet size, and scheduling intervals based on network conditions. By adjusting these parameters dynamically, the patent achieves efficient file transfer without requiring proportional increases in network infrastructure or resource allocation.
3Speed
If massive files are transmitted during peak traffic periods, then delivery speed is improved, but network congestion and impact increase
Solution Approach 1:
The system performs preliminary network condition assessment and schedules file segment transmissions for off-peak periods in advance. By planning and executing transmissions during predetermined low-traffic windows, the patent achieves fast delivery without causing network congestion, as the network is already in a low-utilization state during these periods.

AI summary
An adaptive file delivery system and method transmits a data file, such as an audio-video file, over a network or collection of networks in segments, each segment transmitted during a different time period. Each time period has a transmission portion to transmit its associated file segment and a wait portion in which no further interaction with the network occurs regarding the transmitted segment. In some implementations, the duration of the transmission portion of each time period is sufficient to reach a steady-state throughput condition, which allows the traffic load status of the network or networks to be determined from rate measurements of file segment transmissions. The duration of the wait portion of each time period is at least long enough to limit the average rate of file segment transmission to adapt to network traffic load variations while causing the entire file to be delivered in a predetermined delivery deadline.
