Core Network Congestion Control via Source Terminal Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting network congestion often lead to incorrect identification of the source of congestion, resulting in ineffective congestion alleviation and potential worsening of the congestion state, as they mistakenly target the wrong terminal.
Innovation Solution
A method that extracts adjacent data packets from an output port queue, acquires their source terminal address information, and transmits congestion information to the source terminal transmitting the most data packets, allowing for accurate identification and rate reduction of the congesting terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the core network entity samples a single data packet from the output port queue to detect congestion, then the detection process is simple and fast, but the source terminal identification becomes inaccurate leading to wrong congestion causality judgment
Solution Approach 1:
The patent combines multiple data packet samples into a single detection set, analyzing the source terminal addresses collectively rather than individually. By merging the information from multiple packets, the system achieves both efficient processing and accurate identification of the terminal causing congestion.
Solution Approach 2:
The patent creates a virtual representation of the congestion situation by copying source terminal address information from multiple data packets into a detection set. This virtual model allows the system to analyze congestion causality without directly interfering with the actual data transmission flow.
2Extent of automation
If the core network entity transmits congestion information to the incorrectly identified source terminal, then the congestion control mechanism operates, but the actual congestion source continues to transmit at high rate causing congestion to persist or worsen
Solution Approach 1:
The patent implements a feedback mechanism where the core network entity continuously monitors the output port queue and adjusts congestion control actions based on updated source terminal identification. The system uses the detected congestion state and identified source terminal to send targeted congestion information, creating a closed-loop control system that improves reliability over time.
3Duration of action of stationary object
If the core network entity samples data packets periodically from the output port queue, then the congestion detection is continuous, but the complexity of tracking and identifying the correct source terminal increases
Solution Approach 1:
The patent extracts only the essential source terminal address information from the sampled data packets, separating this key identifier from other packet data. By taking out only the necessary information for congestion analysis, the system maintains continuous detection capability while minimizing the complexity of tracking and processing.
