Adaptive Latency Scheduling for Event-Based Processors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current event-based processing systems suffer from processing lag due to throttling, which results in high latency for latency-sensitive event-based processors, leading to potential loss of functionality as events are delayed, especially during high event loads.
Innovation Solution
Implement a dynamic prioritization system that monitors latency-sensitive event-based processors, allowing them to process more events at a higher frequency when latency exceeds predefined thresholds, and reverting to normal processing when latency returns to acceptable levels to conserve system resources.

1Productivity
If throttling is applied to constrain the number of events processed by each event-based processor, then system resource allocation is improved, but processing latency increases for latency-sensitive processors
Solution Approach 1:
The system dynamically adjusts the number of events that can be processed by each event-based processor based on real-time latency measurements. The constraint on the number of events is not fixed but varies according to whether the processor is latency-sensitive and currently experiencing high latency, allowing the system to optimize between resource allocation and processing speed adaptively
Solution Approach 2:
Different event-based processors are treated differently based on their latency sensitivity and current performance state. Latency-sensitive processors experiencing high latency receive relaxed constraints and higher processing priority, while non-latency-sensitive or well-performing processors maintain standard constraints, creating localized optimization rather than uniform treatment
2Device complexity
If all event-based processors are given equal priority in processing events, then system simplicity is maintained, but latency-sensitive processors experience processing lag during high event loads
Solution Approach 1:
The system continuously measures latency for latency-sensitive event-based processors and uses this feedback to dynamically adjust processing priorities and constraints. When latency exceeds thresholds, the system responds by relaxing event processing constraints and increasing priority, creating a closed-loop control mechanism that maintains functionality reliability
Solution Approach 2:
Processor priority and event processing constraints are not static but dynamically adjusted based on real-time latency conditions. The system transitions from equal priority treatment to differentiated priority levels when latency-sensitive processors are detected to be experiencing delays, maintaining simplicity while improving reliability through dynamic adaptation

AI summary
The latency corresponding to a latency-sensitive event-based processor is evaluated to determine whether the latency-sensitive event-based processor (EBP) should be prioritized. If so, constraints on the number of events that the latency-sensitive EBP can process are relaxed and the frequency with which the latency-sensitive EBP can process events is increased. At a next latency evaluation, if the latency-sensitive EBP no longer meets criteria for prioritization, the constraint on the number of events is returned to a nominal level, as is the frequency with which the latency-sensitive EBP can process events.
