1Quantity of substance
If typical compression techniques are used to reduce network infrastructure cost, then the number of optical or wireless links is reduced, but compression jitter and latency jitter are introduced along with signal degradation
Solution Approach 1:
The patent segments the data stream into multiple sub-streams and processes each sub-stream independently through parallel compression engines. This segmentation allows the system to achieve higher compression ratios while maintaining near-zero jitter by processing smaller data units in parallel, thereby reducing the overall latency and signal degradation while still reducing the number of required links.
Solution Approach 2:
The patent implements dynamic compression ratio adjustment where the compression ratio is varied across different sub-streams based on their individual characteristics and current system conditions. This dynamic approach allows the system to optimize compression performance while maintaining near-zero jitter by adapting the compression aggressiveness to match the data characteristics and network conditions, thus reducing links without sacrificing reliability.
2Quantity of substance
If compression ratio is increased to reduce infrastructure cost, then fewer links are needed, but latency jitter and signal degradation worsen
Solution Approach 1:
By dividing the data stream into multiple sub-streams and processing them in parallel, the patent achieves higher effective compression ratios without increasing latency jitter. Each sub-stream is compressed independently with controlled compression ratios, and the parallel processing ensures that the overall latency remains low while the aggregate data rate reduction allows fewer links to be used.
Solution Approach 2:
The patent merges multiple parallel compression operations into a unified output stream. By combining the results of multiple independent compression engines working on different sub-streams simultaneously, the system achieves high compression ratios while maintaining low latency jitter through the parallel architecture, thus reducing the number of required links without time loss.
3Ease of manufacture
If more compression is applied to reduce infrastructure cost, then implementation cost decreases, but device complexity increases due to need for sophisticated compression algorithms
Solution Approach 1:
The patent divides the complex compression task into multiple simpler sub-tasks, each handled by a separate compression engine processing a specific sub-stream. This segmentation allows the use of simpler, more manageable compression algorithms in each parallel engine while achieving high overall compression through the combination of multiple engines, thereby reducing infrastructure cost without excessive device complexity.
Solution Approach 2:
The patent implements a universal compression framework where multiple parallel compression engines can use the same or different compression algorithms. This multi-functional architecture allows the system to achieve high compression ratios through parallel processing without requiring each individual engine to be overly complex, thus reducing infrastructure cost while keeping device complexity manageable through algorithm standardization and parallelization.
