Traffic Control Device Proactive Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling network bandwidth in video distribution systems react delayed to changes in traffic volume, as they reduce bandwidth based on current conditions rather than anticipating future increases.
Innovation Solution
A control device with an information analysis unit to measure communication volume, a reduction target selection unit to identify flows with trending volume changes, and a traffic control unit to reduce bandwidth proactively, selecting flows with rising communication volume rankings before they peak.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bandwidth reduction is performed based on current traffic condition measurement, then network congestion can be controlled, but the reaction to traffic volume changes is delayed
Solution Approach 1:
The system performs preliminary actions by selecting victim streams based on current traffic conditions and predicts future bandwidth requirements. This allows bandwidth reduction to be applied proactively before congestion occurs, rather than reactively after congestion is detected, thereby reducing reaction delay while maintaining reliable congestion control.
2Quantity of substance
If bandwidth reduction is applied to victim streams, then overall traffic volume is reduced, but the selection of victim streams may not be optimal for maintaining service quality
Solution Approach 1:
The system uses feedback mechanisms by continuously monitoring traffic conditions and adjusting victim stream selection accordingly. The selection process considers current bandwidth usage patterns and service quality requirements, ensuring that bandwidth reduction is applied optimally to maintain overall service quality while effectively reducing traffic volume.

AI summary
A control device includes an information analysis unit that measures communication volume in each flow included in input traffic and generates traffic information including information representing at least the measured communication volume of each of the flows and a time at which measurement is taken; a reduction target selection unit that generates ranking information representing a ranking which is a rank order of a communication volume of each of the flows in the input traffic and selects a flow having the ranking that has a trend to change in a particular direction as a reduction target flow whose communication volume is to be reduced; and a traffic control unit that reduces a communication volume on the reduction target flow, and transmits the reduction target flow subjected to the reduction processing together with another flow included in the input traffic as output traffic.
