Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing optical communication networks, fixed payload block quantities lead to underutilization or failure in bandwidth allocation due to mismatched service bandwidths, resulting in inefficient resource utilization and transmission failures.
Innovation Solution
A method to dynamically adjust the bandwidth of a first payload subarea by reallocating resources from a second payload subarea, allowing flexible allocation based on service requirements, including changing the division manner, arrangement, or size of payload blocks and timeslots to match service bandwidths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the bandwidth of services is increased beyond the first payload subarea capacity, then more services can be transmitted, but service transmission fails due to mapping limitations
Solution Approach 1:
The patent applies universality by enabling the first payload subarea to dynamically serve multiple service bandwidth requirements. Through bandwidth adjustment mechanisms, the same payload subarea can adapt to different service capacities, allowing it to function universally for various bandwidth demands rather than being fixed for a single capacity level
Solution Approach 2:
The patent implements dynamics by making the bandwidth of the first payload subarea adjustable rather than fixed. The bandwidth can be dynamically increased or decreased based on service requirements, transforming a static resource allocation system into a dynamic one that responds to changing transmission needs
2Reliability
If the bandwidth of services is decreased, then service transmission succeeds, but bandwidth resource utilization of the transmission frame is reduced
Solution Approach 1:
The patent applies dynamics by enabling the first payload subarea bandwidth to be adjusted downward when service requirements decrease. This prevents fixed bandwidth allocation waste by allowing the system to dynamically reduce payload subarea bandwidth to match actual service needs, thereby maintaining high resource utilization
Solution Approach 2:
The patent implements parameter changes by modifying the bandwidth parameter of the first payload subarea based on service requirements. When services are decreased, the bandwidth parameter is adjusted downward, and when services are increased, the bandwidth parameter is adjusted upward, optimizing resource utilization across different operating conditions
3Device complexity
If the quantity of payload blocks is fixed, then the transmission frame structure is simple, but bandwidth resource utilization is inefficient due to mismatched service bandwidths
Solution Approach 1:
The patent applies dynamics by making the quantity of payload blocks adjustable rather than fixed. The system can dynamically change the number of payload blocks in the first payload subarea based on service bandwidth requirements, transforming a static block allocation system into a dynamic one that optimizes resource utilization
Solution Approach 2:
The patent implements segmentation by dividing the payload area into multiple payload blocks that can be independently allocated. This segmentation allows flexible reconfiguration of block quantities in the first payload subarea to match service requirements while maintaining the overall transmission frame structure
