Content Delivery System Bandwidth Constriction Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content delivery systems face bandwidth constriction issues during high demand periods, leading to denied user requests for content delivery.
Innovation Solution
The system employs multiple allocated bandwidths within a single delivery path and across multiple content delivery paths to manage bandwidth constriction. It allows requested content to be stored on a network DVR for later viewing and switches delivery between VoD and SDV allocated bandwidths as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple allocated bandwidths and multiple content delivery paths are employed, then bandwidth constriction is resolved and content delivery effectiveness is improved, but system complexity increases
Solution Approach 1:
The patent segments the content delivery system into multiple independent delivery paths (VoD path and SDV path) with separate bandwidth allocations. This segmentation allows the system to bypass bandwidth constriction by switching between paths without requiring complex end-to-end redesign, thus improving productivity while controlling complexity through modular architecture.
Solution Approach 2:
The patent introduces an intermediary component (content delivery network with multiple paths) that mediates between the content source and the end user. This intermediary provides alternative routes around bandwidth constrictions, resolving the contradiction by adding delivery flexibility without requiring changes to the core content delivery infrastructure.
2Reliability
If content is stored on network DVR for later viewing, then bandwidth constriction is avoided, but user waiting time increases
Solution Approach 1:
The patent implements dynamic path selection that adapts to real-time bandwidth conditions. When bandwidth is available, content is delivered immediately via the VoD path; when bandwidth is constrained, the system dynamically switches to storing content on network DVR for later delivery via SDV path. This dynamic adaptation resolves the contradiction by optimizing between reliability and time loss based on current system state.
Solution Approach 2:
The patent changes the delivery parameter from immediate streaming to scheduled delivery when bandwidth constriction is detected. By modifying the delivery timing parameter and using network DVR for temporary storage, the system ensures reliable content delivery while minimizing user waiting time through efficient scheduling and notification mechanisms.
