Execution Offset Rate Limiter for Multi-Flow Traffic Pacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices struggle to pace and limit the rate of multiple data flows simultaneously, leading to traffic congestion and bandwidth issues when transmitting multiple streams of data, as they fail to enforce uniform pacing across multiple flows due to hardware limitations.
Innovation Solution
Implementing an execution offset rate limiter that receives an offset value to determine a sequence for executing workloads, ensuring each workload is transmitted at a selected rate with timing offsets between them, thereby pacing overall traffic and preventing congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multiple data flows are transmitted simultaneously without execution offset, then transmission speed is improved, but traffic congestion and bandwidth issues occur
Solution Approach 1:
The rate limiter enforces periodic transmission by executing workloads at fixed time intervals determined by an offset value. Multiple data flows are transmitted in a periodic sequence rather than simultaneously, with each flow executed at its designated time slot, thereby maintaining transmission speed while preventing traffic congestion through structured periodic action.
Solution Approach 2:
The system performs preliminary action by calculating and establishing execution offsets for multiple data flows before transmission begins. The offset value is determined in advance to sequence the execution of workloads, ensuring that transmission occurs in a controlled manner that prevents congestion while maintaining overall transmission efficiency.
2Manufacturing precision
If conventional rate limiting is applied to single workload, then pacing accuracy is improved, but inability to handle multiple flows simultaneously occurs
Solution Approach 1:
The rate limiting function is segmented to handle multiple workloads independently. Instead of a single rate limiter for one flow, the system divides the rate limiting capability across multiple workloads, with each workload receiving its own offset-based pacing control. This segmentation enables precise pacing accuracy for each individual flow while simultaneously managing multiple flows without interference.
Solution Approach 2:
The rate limiter is designed with multi-functionality to simultaneously manage multiple data flows. By incorporating offset value-based sequencing, the single rate limiting mechanism becomes universal, capable of handling any number of workloads with consistent pacing accuracy, thereby achieving both precision and versatility.
3Productivity
If multiple flows transmit packets at the same time, then device resource utilization is improved, but burst traffic and congestion occur
Solution Approach 1:
The system transforms simultaneous packet transmission into periodic transmission by enforcing time-based offsets between workload executions. Device resources remain fully utilized through continuous periodic execution of multiple workloads, while burst traffic is eliminated by spacing transmissions at regular intervals determined by the offset value, thus maintaining productivity without generating harmful traffic patterns.
