Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If P2MP networking method is used in FTTR system, then a large number of devices can be connected and capacity can be expanded conveniently, but bandwidth allocation becomes uneven and delay increases
Solution Approach 1:
The patent implements preliminary action by having the optical gateway pre-analyze service requirements and proactively allocate bandwidth resources before services are actually accessed. The system collects service subscription information, identifies service types (VR, IPTV, voice, etc.), and pre-configures bandwidth allocation strategies, thereby avoiding delay when services are activated.
Solution Approach 2:
The patent applies dynamics by implementing dynamic bandwidth allocation that adapts to changing service requirements. The optical gateway continuously monitors service types and adjusts bandwidth allocation in real-time, transitioning from static to dynamic resource distribution to maintain optimal performance as services are added or removed.
2Adaptability or versatility
If P2MP networking method is used in FTTR system, then a large number of devices can be connected, but bandwidth allocation becomes uneven affecting user experience
Solution Approach 1:
The patent implements local quality by tailoring bandwidth allocation to specific service requirements and user needs. Different services (VR, IPTV, voice) receive customized bandwidth allocations based on their individual characteristics, ensuring each service gets appropriate resources rather than uniform distribution.
Solution Approach 2:
The patent applies parameter changes by adjusting bandwidth allocation parameters based on service types and requirements. The system modifies allocation parameters dynamically according to service characteristics, transforming from fixed parameter allocation to adaptive parameter adjustment to achieve fair and efficient resource distribution.
3Adaptability or versatility
If two levels of bandwidth scheduling are implemented, then bandwidth can be managed at multiple levels, but scheduling complexity increases and efficiency decreases
Solution Approach 1:
The patent implements merging by consolidating the two-level bandwidth scheduling into a unified scheduling mechanism at the optical gateway. Instead of separate scheduling layers, the system integrates service recognition, requirement analysis, and bandwidth allocation into a single coordinated process, reducing complexity while maintaining management flexibility.
Solution Approach 2:
The patent applies universality by creating a multi-functional bandwidth scheduling system that handles multiple service types and allocation scenarios through a single unified framework. The optical gateway performs multiple functions (service identification, requirement analysis, bandwidth allocation) within one scheduling mechanism, eliminating the need for separate specialized schedulers.
