Universal Timeout Enforcement in Distributed Computing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed computing environments, conventional timeout mechanisms are inefficient as they apply a timeout for each network hop independently, leading to unpredictable and prolonged effective timeouts, especially when multiple hops are required, which can result in increased latency and poor performance.
Innovation Solution
A universal timeout feature is introduced that enforces a defined timeout period across a block of code regardless of the number of network hops, using a try-with-resources statement in programming languages like Java to ensure that the execution of a thread is completed within the specified time, triggering an interrupt if not, thus preventing prolonged waits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a timeout is applied independently for each network hop, then each hop can be monitored for responsiveness, but the effective timeout becomes unpredictable and prolonged due to multiple hops
Solution Approach 1:
The patent merges multiple independent timeout mechanisms into a single universal timeout that spans the entire distributed transaction across multiple network hops. Instead of applying separate timeouts at each hop boundary, a unified timeout envelope is established that encompasses the complete transaction lifecycle, preventing the cumulative timeout effect while maintaining monitoring capability.
Solution Approach 2:
The universal timeout mechanism serves multiple functions simultaneously: it monitors the entire distributed transaction, coordinates across all participating nodes, and provides a single predictable timeout boundary. This multi-functional approach replaces the need for multiple separate timeout settings while improving both reliability and predictability.
2Measurement precision
If a timeout of 1 second is applied per hop in a three-hop execution, then each network traversal is monitored, but the total effective timeout extends to up to three seconds
Solution Approach 1:
The timeout mechanism transitions from a static per-hop setting to a dynamic universal timeout that adapts to the overall transaction requirements. The system dynamically establishes a single timeout boundary that reflects the actual service level agreement for the complete distributed operation, rather than applying rigid per-hop constraints that accumulate.
3Adaptability or versatility
If multiple independent timeout settings are used across network hops, then each segment can be optimized, but the overall timeout behavior becomes unpredictable
Solution Approach 1:
While maintaining the segmented architecture of distributed computing, the patent segments the timeout management function by establishing a universal timeout envelope that spans all segments. Each node within the distributed system participates in the same unified timeout regime, ensuring consistent behavior across all segments while preserving the benefits of distributed architecture.
Data Source
AI summary
A system and method for supporting universal timeout in a distributed computing environment. The universal timeout feature can enforce a defined timeout for a block (or group of blocks) or code executing on a thread regardless of the number of network hops required to effectuate the code. The universal timeout feature allows a thread to express a timeout which is respected across the platform thereby improving timeout functionality compared to prior timeout implementations which pass a timeout between functions. Universal timeout may be implemented using a try-with-resources paradigm where the timeout period is treated as a resource.
