Transmission Rate Feedback for Buffer Bloat Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data communication systems face challenges due to buffer bloat, particularly in high-priority data transmission, where lower-priority data remains in buffers, and detecting such issues is difficult.
Innovation Solution
Implementing a system to compare transmission and reception rates, adjusting the transmission rate based on these rates to mitigate buffer bloat, using methods like binary search and sigmoid functions for rate adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If buffers are used to store and buffer data being communicated, then data transmission is facilitated, but buffer bloat occurs and lower-priority data remains in buffers
Solution Approach 1:
The patent implements a feedback mechanism where the receiver compares the transmission rate with the reception rate and sends control inputs back to the transmitter. This feedback loop enables the system to detect buffer bloat conditions and adjust transmission rates dynamically, resolving the contradiction by preventing buffer overflow while maintaining transmission efficiency.
Solution Approach 2:
The patent makes the transmission rate dynamic rather than fixed. The transmission rate is continuously adjusted based on real-time comparison between transmission and reception rates, allowing the system to adapt to changing buffer conditions and prevent buffer bloat while maintaining optimal data transmission.
2Speed
If higher priority data is processed at acceptable speed, then priority data transmission is improved, but buffers become loaded with lower priority data
Solution Approach 1:
The feedback mechanism monitors the reception rate and compares it with the transmission rate to detect when lower-priority data is accumulating in buffers. When buffer bloat is detected, the system adjusts the transmission rate to prevent further accumulation, thus resolving the contradiction between processing priority data quickly and preventing buffer overload with lower-priority data.
3Productivity
If transmission rate is increased to improve data communication throughput, then productivity is improved, but buffer bloat detection becomes more challenging
Solution Approach 1:
The patent implements a feedback mechanism where the receiver continuously monitors the reception rate and compares it with the transmission rate. This feedback approach enables detection of buffer bloat even at high transmission rates by identifying the discrepancy between how fast data is sent and how fast it is received, thus resolving the contradiction between high throughput and buffer bloat detection.
4Reliability
If transmission rate adjustment is implemented to prevent buffer overflow, then buffer management is improved, but transmission rate flexibility is reduced
Solution Approach 1:
The patent implements dynamic transmission rate adjustment where the rate is continuously modified based on real-time feedback from the receiver. This dynamic approach maintains reliability by preventing buffer overflow while preserving flexibility, as the transmission rate can adapt to different network conditions and buffer states rather than being constrained to fixed rates.

AI summary
Aspects of the disclosure are directed to data communication with transmission rate adjustment. As may be implemented in accordance with one or more embodiments herein, such aspects may involve comparing the transmission rate at which packets are communicated from a transmitter, with a reception rate at which the packets are received at a receiver. The transmission rate at which further packets are communicated from the transmitter is adjusted in response to and/or otherwise based on the comparison.
