Remote Meshed Flow Congestion Control via Centralized Traffic Matrices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing congestion in meshed packet mode telecommunication networks is challenging due to the unpredictability of traffic patterns and the complexity of interconnecting multiple central and remote sites, leading to difficulties in guaranteeing Quality of Service, especially when a large number of remote sites communicate with a limited number of central sites.
Innovation Solution
A method and device for remotely controlling congestion by dynamically associating remote sites with central sites based on actual traffic, establishing a dynamic traffic matrix, and calculating traffic management rules to detect pre-congestion and distribute resources effectively, allowing for real-time traffic management without the need for active devices at remote sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If active devices for managing flow are installed at all remote sites, then congestion control precision is improved, but device complexity and infrastructure cost increase
Solution Approach 1:
The system segments the congestion control function by deploying active flow management devices only at central sites rather than at every remote site. The central sites perform the complex congestion detection and control calculations, while remote sites participate through simpler agents that report traffic status and receive control rules, thus reducing overall infrastructure complexity while maintaining control precision.
Solution Approach 2:
The patent introduces an intermediary mechanism where central sites act as mediators that collect traffic information from multiple remote sites, perform centralized congestion analysis, and distribute control rules back to the remote sites. This intermediary approach allows precise congestion control without requiring complex active devices at each remote site.
2Reliability
If flow management devices are deployed at all sites, then Quality of Service guarantee is improved, but deployment complexity and cost increase
Solution Approach 1:
The deployment is segmented into central sites equipped with full flow management capabilities and remote sites with simpler agents. This segmentation maintains QoS guarantees through centralized control while significantly simplifying deployment at remote locations, as the complex management functions are consolidated at central sites.
Solution Approach 2:
The central sites perform multiple functions including congestion detection, traffic matrix calculation, control rule generation, and distribution to multiple remote sites. This multi-functionality at central sites eliminates the need for duplicate complex devices at each remote site, simplifying overall deployment while maintaining QoS.
3Loss of energy
If centralized control at central sites is implemented, then infrastructure cost is reduced, but real-time traffic management capability may be compromised
Solution Approach 1:
The system performs preliminary actions by continuously calculating and updating traffic matrices at central sites based on reported traffic information. Control rules are pre-computed and stored, ready for immediate deployment when congestion conditions are detected, thus maintaining real-time responsiveness despite centralized architecture.
Solution Approach 2:
The patent implements a feedback mechanism where remote site agents continuously report traffic information to central sites. The central sites use this feedback to update traffic matrices and recalculate control rules in real-time, ensuring that centralized control remains responsive to changing network conditions.
