Network Content Scaling Architecture for Bandwidth Oversubscription
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication networks face challenges in managing increased demand due to advanced mobile device capabilities, such as video calls and conferencing, leading to bandwidth oversubscription and symbolization integrity issues, which can result in service degradation.
Innovation Solution
An architecture that includes a fault management component to detect predetermined fault conditions and a scaling component to reduce content resolution, applying a codec with a lesser bitrate and inserting forward error correction codes, thereby mitigating errors without significantly increasing bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content resolution is maintained at high quality, then service quality is improved, but bandwidth consumption increases leading to oversubscription
Solution Approach 1:
The system dynamically adjusts content resolution based on real-time network conditions. The fault management component monitors network status and controls the scaling component to adaptively change resolution, allowing the system to maintain high quality when bandwidth is充足 and reduce quality when bandwidth is constrained, thus resolving the contradiction between service quality and bandwidth consumption
Solution Approach 2:
The scaling component changes the resolution parameter of content based on detected fault conditions. By modifying this key parameter in response to network status, the system can maintain service quality within available bandwidth constraints, preventing oversubscription while preserving acceptable service quality
2Reliability
If error correction codes are inserted to mitigate symbolization integrity issues, then reliability is improved, but bandwidth consumption increases
Solution Approach 1:
The system applies error correction in a partial manner, inserting forward error correction codes only when fault conditions are detected by the fault management component. This selective application provides necessary reliability improvements while avoiding continuous bandwidth consumption for error correction, thus resolving the contradiction between reliability and bandwidth usage
3Quantity of substance
If content resolution is reduced to alleviate network stress, then bandwidth consumption is reduced, but service quality deteriorates
Solution Approach 1:
The fault management component provides continuous feedback about network conditions to the scaling component. This feedback mechanism allows the system to reduce resolution only when and where necessary to alleviate network stress, while maintaining high resolution when network conditions permit, thus preventing service quality deterioration while managing bandwidth consumption
Solution Approach 2:
The system performs preliminary scaling of content resolution before transmission when network congestion is anticipated or detected. By pre-processing content at appropriate resolution levels based on predicted or current network conditions, the system avoids the need for extreme quality reduction during actual transmission, thus managing bandwidth while preserving adequate service quality

AI summary
An architecture is provided that can scale content resolution in order to mitigate errors in a provisioned service of a communication network, such as a wireless service or a femtocell service that integrates with DSL or other broadband carriers. The architecture can identify fault conditions relating to e.g., bandwidth oversubscription or symbolization integrity. Based upon such identification, the architecture can alter encoding format codecs of certain types of content in order to reduce their resolution/quality, thereby mitigating bandwidth oversubscription fault conditions or freeing up space (without necessarily increasing bandwidth) to insert additional FEC code.
