Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face challenges in maintaining consistent latency across all endpoints, which can impact the effectiveness of applications that require synchronized data transmission, such as financial trading, e-sports, and online gaming.
Innovation Solution
The implementation of a deterministic dynamic traffic shaping system, which includes active ranging devices and passive optical couplers, allows for the equalization of latency across communication networks by electronically managing and adjusting latency rather than physically modifying fiber lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If physical fiber lengths are modified to equalize latency, then latency consistency is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent replaces the mechanical/physical approach of cutting and splicing fiber cables with an electronic/software-based latency adjustment mechanism. The system uses electronic traffic shaping and packet buffering to artificially equalize latency across different fiber lengths, eliminating the need for physical fiber modifications while achieving the same latency consistency goal.
Solution Approach 2:
The patent changes the approach from modifying physical parameters (fiber length) to modifying operational parameters (packet transmission timing, buffering duration). By dynamically adjusting these parameters through software control, the system achieves latency equalization without physical intervention, reducing complexity and installation difficulty.
2Manufacturing precision
If fiber lengths are physically adjusted to achieve equal latency, then latency equalization is improved, but network downtime and operational disruption increase
Solution Approach 1:
The patent implements latency equalization through software configuration that can be applied immediately without physical intervention. The system pre-calculates required latency adjustments and applies them through electronic traffic shaping, allowing continuous network operation during configuration and eliminating network downtime associated with physical fiber modifications.
Solution Approach 2:
By replacing physical fiber splicing and cable replacement with electronic latency adjustment mechanisms, the patent eliminates the time-consuming physical work while maintaining latency equalization effectiveness. The electronic system can be configured and adjusted instantly without network disruption.
3Measurement precision
If active ranging devices and passive optical couplers are used for latency management, then latency control precision is improved, but device complexity increases
Solution Approach 1:
The patent introduces passive optical couplers as intermediary devices that enable latency measurement and adjustment without actively processing or generating traffic. These couplers passively split and combine optical signals, allowing ranging measurements to be performed on a portion of the traffic without disrupting the main data flow, thus providing precise latency control with minimal added complexity.
Solution Approach 2:
The patent segments the optical signal into different paths using passive couplers - one path for data traffic and another for ranging/measurement traffic. This segmentation allows simultaneous operation of data transmission and latency measurement/adjustment without interference, achieving precise latency control while keeping each component relatively simple.
