Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the IBM adjusts bandwidth allocation when limits are exceeded, then bandwidth quota compliance is improved, but network stability deteriorates due to jitter and fluctuations
Solution Approach 1:
The system performs preliminary actions by proactively identifying entities approaching their bandwidth limits and preemptively adjusting their allocations before they exceed quotas. This prevents the need for disruptive reactive adjustments and maintains network stability. The IBM monitors bandwidth usage trends and takes preventive measures to ensure compliance while avoiding jitter.
Solution Approach 2:
The patent implements dynamic bandwidth adjustment mechanisms that continuously adapt allocation based on real-time network conditions and entity usage patterns. Rather than making discrete, disruptive changes when limits are exceeded, the system dynamically smooths transitions and adjusts allocations progressively, maintaining both quota compliance and network stability through continuous adaptation.
2Productivity
If the IBM allows entities to achieve maximum configured bandwidth, then bandwidth utilization is improved, but jitter increases due to drastic fluctuations when exceeding allocated quotas
Solution Approach 1:
The system applies beforehand cushioning by implementing buffer mechanisms and gradual transition protocols when adjusting bandwidth allocations. When entities approach or exceed their allocated quotas, the system cushions the impact through progressive adjustments and smoothing algorithms, preventing drastic fluctuations that cause jitter while still allowing efficient bandwidth utilization.
Solution Approach 2:
The patent utilizes parameter changes by dynamically modifying bandwidth allocation parameters based on real-time conditions. The system adjusts allocation rates, transition speeds, and threshold values to optimize both utilization and stability. By changing parameters smoothly rather than making abrupt adjustments, the system maintains high bandwidth utilization while minimizing jitter.
3Adaptability or versatility
If multiple bandwidth flow control mechanisms are used, then bandwidth management capability is improved, but system complexity increases
Solution Approach 1:
The patent merges multiple bandwidth flow control mechanisms into a unified, integrated system. The in-route bandwidth manager (IBM) consolidates various control functions and coordination mechanisms into a single centralized entity that manages allocations across the multi-tiered network. This merging approach maintains the versatility and adaptability of multiple mechanisms while reducing system complexity through unified management and coordination.

AI summary
Systems and methods for dynamic bandwidth allocation and jitter handling in multi-tiered satellite networks such as virtual communication networks and/or physical communication networks. The system includes bandwidth distributing (BD) unit, in-route group managers (IGMs), in-route bandwidth manager (IBM). The system functions in multi-tier network entity management mode, and multi-beam management mode. The system operates by periodically collecting bandwidth reports from IGMs. The BD unit analyzes data in report and compares aggregated bandwidth demand with pre-defined thresholds. If thresholds are exceeded, system switches to multi-tier network entity management mode. In this mode, BD unit determines individual bandwidth adjustments for virtual network and beams and allocates bandwidth for individual devices within virtual network. Further, BD unit transmits this information to IBM, which applies allocations, and receives and transmits a scaling factor back to IGM indicating utilization of allocated bandwidth. Further, BD unit switches back to multi-beam management mode based on comparison result.
