Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dynamic bandwidth allocation (DBA) in point-to-multipoint optical networks is suboptimal due to fixed traffic descriptor parameters that do not adapt to changing network requirements and active applications, leading to inefficient bandwidth usage and quality of service.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed traffic descriptor parameters are used for bandwidth allocation, then the network configuration is simple and stable, but the bandwidth allocation becomes suboptimal when network requirements and applications vary over time
Solution Approach 1:
The patent applies dynamics by transitioning from fixed static traffic descriptor parameters to dynamic parameters that can change over time. The system periodically updates traffic descriptor parameters based on current network conditions and bandwidth demands, allowing the bandwidth allocation to adapt dynamically while maintaining operational simplicity through automated processes.
Solution Approach 2:
The patent implements parameter changes by modifying traffic descriptor parameters (such as bandwidth allocation values, priority levels, and service types) based on observed network conditions. The system monitors network utilization and bandwidth demands, then adjusts the parameters accordingly to optimize performance without requiring complex manual reconfiguration.
2Reliability
If conservative bandwidth allocations are used, then quality of service is maintained under all conditions, but bandwidth efficiency decreases when network demand is lower
Solution Approach 1:
The patent applies feedback by continuously monitoring network conditions, bandwidth utilization, and service quality metrics. Based on this feedback, the system dynamically adjusts traffic descriptor parameters to maintain quality of service when needed while optimizing bandwidth efficiency during periods of lower demand, avoiding both over-provisioning and under-provisioning.
Solution Approach 2:
The system transitions from static conservative allocations to dynamic allocations that adjust based on real-time network conditions. This allows the network to maintain reliability when demand is high while improving productivity when demand is lower, eliminating the need for permanently conservative allocations.
3Ease of manufacture
If manual provisioning of traffic descriptor parameters is performed, then initial configuration is straightforward, but the system cannot adapt to varying network requirements over time
Solution Approach 1:
The patent implements self-service by enabling the network system to automatically adjust its own traffic descriptor parameters based on monitored network conditions. After simple initial configuration, the system autonomously optimizes bandwidth allocation without requiring manual intervention, combining ease of setup with continuous adaptability to changing requirements.
Solution Approach 2:
The system performs preliminary action by establishing baseline traffic descriptor parameters during initial configuration, then uses automated monitoring and adjustment mechanisms to adapt these parameters over time. This approach maintains the simplicity of initial setup while enabling subsequent automatic adaptation to varying network demands.
