Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bandwidth management in packet optical communication networks relies on manual intervention, leading to inefficiencies such as under-provisioning or over-provisioning, which affects application performance and resource utilization.
Innovation Solution
Implementing a system that dynamically adjusts data transport rates in packet optical networks by monitoring data usage and computing optimal rates for Carrier Ethernet services, allowing for real-time allocation and re-allocation of time slots based on historical data and changing requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual bandwidth provisioning is used, then service deployment is simple, but resource utilization efficiency deteriorates due to under-provisioning or over-provisioning
Solution Approach 1:
The system enables self-service through automated bandwidth management where the network infrastructure itself monitors traffic patterns, computes optimal bandwidth allocation, and adjusts rates without manual intervention. The bandwidth management controller automatically detects traffic demands and reconfigures network resources based on computed rates, allowing the system to serve itself rather than requiring manual provisioning for each change.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring actual traffic patterns and comparing them against current bandwidth allocations. The bandwidth management controller receives feedback about traffic demands, computes optimal adjustments, and applies configuration changes accordingly. This closed-loop feedback enables the system to adapt to changing conditions and maintain optimal resource utilization.
2Stability of the object's composition
If static bandwidth allocation is used, then network configuration is stable, but adaptability to changing application demands deteriorates
Solution Approach 1:
The system transitions from static to dynamic bandwidth allocation by implementing continuous monitoring and automated adjustment capabilities. The bandwidth management controller dynamically computes optimal bandwidth rates based on real-time traffic patterns and automatically reconfigures network resources. This dynamic approach allows the network to adapt to changing application demands while maintaining operational stability through controlled, automated changes rather than manual interventions.
3Reliability
If over-provisioning is used for critical applications, then service reliability is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The system changes the bandwidth allocation parameter dynamically based on actual traffic conditions and application requirements. Instead of fixed over-provisioning, the bandwidth management controller computes optimal bandwidth rates by analyzing traffic patterns and adjusts allocations accordingly. This allows critical applications to receive adequate bandwidth when needed while reducing allocations during low-demand periods, thereby maintaining reliability while improving overall resource utilization efficiency.
