Network Traffic Control via Reaction Point Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Ethernet traffic control methods have poor performance due to random selection of reaction points (RPs) for traffic adjustment, which may not accurately address data stream congestion, leading to inefficient network traffic control.
Innovation Solution
A method where traffic monitoring information from RPs is used to determine and select specific RPs needing traffic adjustment based on congestion conditions, calculating a new traffic value for each RP, and sending this value to perform targeted traffic control, improving accuracy and effectiveness of network traffic management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If random selection of reaction points (RPs) is used for traffic adjustment, then the control process is simple, but the traffic control performance is poor
Solution Approach 1:
The patent implements a feedback mechanism where the congestion point (CP) calculates feedback information based on queue length and queue growth rate, then sends control information to selected RPs. The RPs monitor traffic and provide feedback to the CP, enabling continuous optimization of traffic control based on actual network conditions, thereby improving control performance while maintaining operational simplicity.
Solution Approach 2:
The patent changes the selection criterion from random selection to selection based on traffic monitoring information and priority settings. By introducing parameters such as traffic load, queue status, and configurable priority weights, the system can dynamically select the most appropriate RPs for traffic adjustment, significantly improving traffic control effectiveness.
2Measurement precision
If traffic monitoring information is collected from all RPs, then the accuracy of RP selection is improved, but the network overhead increases
Solution Approach 1:
The patent applies local quality by allowing different RPs to have different monitoring roles based on their characteristics and network position. Instead of requiring all RPs to perform identical monitoring functions, the system can selectively enable monitoring at specific RPs based on their contribution to congestion detection, reducing overall network overhead while maintaining selection accuracy.
Solution Approach 2:
The patent implements partial action by collecting traffic monitoring information only from RPs that are relevant to specific congestion scenarios. Rather than requiring all RPs to continuously report, the system can selectively gather information from a subset of RPs based on current network conditions and congestion patterns, reducing overhead while maintaining sufficient accuracy for effective traffic control.
3Productivity
If multiple RPs are selected for traffic adjustment, then the traffic control coverage is improved, but the complexity of coordination increases
Solution Approach 1:
The patent applies segmentation by dividing the traffic control function into independent RP units, each capable of autonomous traffic adjustment based on received control information. The CP segments the control task by assigning specific adjustment parameters to different RPs, allowing parallel execution of traffic control at multiple points without requiring complex inter-RP coordination, thus maintaining scalability.

AI summary
A traffic control method and device are provided. The method includes receiving traffic monitoring information of a first service flow reported by a reaction point RP; when a congestion state of a first service flow of a congestion point CP satisfies a congestion condition, determining a reaction point RP needing traffic adjustment from a designated reaction point RP according to the received traffic monitoring information, and calculating, according to the traffic monitoring information, a new traffic value of a first service flow of each of the reaction point RP needing traffic adjustment; sending each calculated new traffic value of a first service flows to a corresponding reaction point RP needing traffic adjustment, so that the reaction point RP performs traffic control on the first service flow of the reaction point RP according to the new traffic value.
