Data Carousel Distribution for Lower-Bandwidth File Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data distribution methods, such as peer-to-peer networking, do not effectively reduce the total network bandwidth required for file distribution, as each user receives a dedicated transmission, leading to server overload and inefficiency.
Innovation Solution
The implementation of data carousels, where a file is divided into portions transmitted across multiple devices, allowing clients to access and reconstruct the file by selecting carousels based on highest throughput and using error correction information to handle missing data, with a carousel directory organizing the topology to optimize distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If peer-to-peer networking is used to distribute files, then the load on the server is distributed across multiple hosts, but the total network bandwidth required remains high because each user receives a dedicated transmission
Solution Approach 1:
The file is divided into multiple data carousels, each containing a portion of the file. Multiple carousels can be transmitted simultaneously over the network, allowing parallel data distribution to multiple users without requiring dedicated full-file transmissions for each user, thus reducing total bandwidth consumption while maintaining server load distribution
Solution Approach 2:
Multiple data carousels are merged into a single multicast transmission stream. Users receive the same carousel data stream simultaneously, and each user reconstructs the complete file by combining portions from different carousels, eliminating redundant transmissions and reducing overall network bandwidth requirements
2Reliability
If each user receives a dedicated transmission of the file, then data delivery is reliable, but network bandwidth is wasted due to redundant transmissions to multiple users
Solution Approach 1:
Multiple users share a single multicast data carousel transmission, eliminating redundant dedicated transmissions. The carousel contains error correction information that enables any user to reconstruct the complete file from the shared data, maintaining reliability while significantly reducing bandwidth consumption through consolidation
Solution Approach 2:
The system changes the transmission parameter from dedicated unicast transmissions to multicast transmissions. By transmitting data once to multiple users simultaneously through the carousel mechanism, the system maintains reliable data delivery while reducing the total number of transmissions and network bandwidth consumption
3Speed
If data carousels are transmitted simultaneously to multiple users, then download speed increases, but network bandwidth requirements increase
Solution Approach 1:
Multiple data carousels are merged into a single multicast stream that can be received simultaneously by multiple users. This allows parallel data retrieval for different users without requiring separate dedicated transmissions, thereby increasing download speed while reducing total network bandwidth consumption through shared transmission
Solution Approach 2:
The file is segmented into multiple carousels that can be transmitted in parallel over the network. Users can simultaneously access different carousels or the same carousel at different positions, enabling parallel data retrieval that increases download speed while the multicast mechanism reduces bandwidth consumption
Data Source
AI summary
Data may be distributed using data carousels. After a device receives the data, or a portion thereof, the device may make available a data carousel that allows others to receive the data. Each data carousel may contain a portion of the data. Data carousels may also contain error correction information that can be used to reconstruct missing portions of the data being distributed. A carousel directory may keep track of the carousel structure and direct the behavior of devices that are receiving data and/or distributing data.
