Content File Recipe Composition for CDN Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Content delivery networks face inefficiencies in bandwidth usage and data retrieval due to the need to repeatedly fetch large amounts of redundant data, leading to potential delays and degraded user experience, especially as digital content sizes increase.
Innovation Solution
Implementing a system where content files are composed using recipes that include instructions to retrieve and reuse similar data, allowing only portions of content data to be stored in a cache, with the remaining data referenced by these recipes, thereby reducing the burden on content delivery nodes and improving network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If content delivery nodes store complete content files locally, then delivery speed improves, but storage requirements and bandwidth usage increase significantly
Solution Approach 1:
The patent segments content files into multiple data portions and stores only selected portions at content delivery nodes. Instead of caching complete files, the system divides content into manageable segments and strategically caches only the most frequently accessed or critical segments, reducing storage requirements while maintaining delivery capability for commonly requested content.
Solution Approach 2:
The patent introduces a new dimension of data reconstruction by creating composite content through combining multiple data portions from different sources. Content delivery nodes can assemble complete content files by retrieving and combining segments from various content files and sources, transforming the traditional single-file caching approach into a multi-source composition system that reduces overall storage needs.
2Reliability
If content delivery nodes retrieve complete content files from content providers, then data accuracy is maintained, but bandwidth consumption and retrieval time increase
Solution Approach 1:
The patent extracts and caches only the essential or frequently accessed data portions from complete content files, rather than caching entire files. Content delivery nodes retrieve and store specific segments that are most likely to be needed, reducing bandwidth consumption during both the initial caching phase and subsequent content delivery operations.
Solution Approach 2:
The patent implements partial action by caching only a subset of content data portions rather than complete files. The system retrieves and caches sufficient data portions to enable reconstruction of commonly requested content, using just enough bandwidth to cache essential segments without the excessive bandwidth consumption of caching complete files.
3Loss of energy
If delta coding is used to reduce bandwidth usage, then transmission efficiency improves, but user experience degrades when delta size is large
Solution Approach 1:
The patent performs preliminary action by pre-caching data portions at content delivery nodes before user requests arrive. Instead of transmitting large deltas in real-time, the system proactively stores content segments at edge nodes in advance, so that when users request content, the data is already locally available or can be quickly assembled from cached segments, eliminating delivery delays.
Solution Approach 2:
The patent creates local copies of data portions at content delivery nodes rather than relying on delta compression and decomposition. By caching actual content segments at edge locations, the system enables direct local retrieval and composition of content without requiring bandwidth-intensive delta transmission and client-side reconstruction, maintaining both low bandwidth usage and fast delivery.
Data Source
AI summary
An embodiment for reusing data in content files includes receiving a request for a content file and retrieving a recipe that includes a series of instructions needed to compose the content file. Data identified by the recipe may then be retrieved from a content file server and the requested content file is composed based on the set of instructions in the recipe. In an example, the recipe is processed by a recipe player to compose a content file. In another embodiment, content files are stored in a cache as a series of instructions for generating them from portions of other content files. In this way, performance in a content delivery network may be improved by reusing similar data in content files.
