LoM Server Rate Control via Health Metrics Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LDAP servers experience performance bottlenecks due to rapid sequential requests, leading to slow responses and potential timeouts, as they spend excessive time processing updates, which degrades the overall system performance and affects user searches.
Innovation Solution
A rate control technique that uses health metrics from the LoM server to dynamically calculate a delay value, which is inserted between requests to control the processing pace of the LoM queue, ensuring timely responses and maintaining service level agreements by pacing updates based on system resources and performance metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the LDAP server processes requests rapidly without delay, then the processing speed is improved, but the system performance degrades due to bottlenecks and timeouts
Solution Approach 1:
The patent implements periodic action by introducing a delay mechanism that pauses between processing requests. The health metrics engine monitors system state and determines appropriate delay intervals, causing the LoM queue to process requests periodically rather than continuously. This periodic processing prevents bottlenecks and timeouts while maintaining acceptable processing speed.
Solution Approach 2:
The patent applies feedback through the health metrics engine that continuously monitors LDAP server performance, queue depth, and system resources. Based on this feedback, the engine dynamically adjusts delay values to optimize processing pace. The feedback loop ensures the system adapts to changing conditions and maintains optimal performance without overwhelming the LDAP master.
2Manufacturing precision
If the LDAP server spends excessive time processing updates, then update processing is thorough, but user search responses become slow
Solution Approach 1:
The patent uses periodic action to balance update processing thoroughness with user search responsiveness. By introducing calculated delays between update processing operations, the system ensures updates are processed adequately while preventing them from blocking user search requests. The periodic pause allows the LDAP master to complete updates without causing timeouts in user searches.
Solution Approach 2:
The patent implements dynamics by making the processing pace adaptive rather than fixed. The health metrics engine dynamically adjusts delay values based on real-time monitoring of update flow, queue depth, and system resources. This dynamic adjustment allows the system to optimize between update processing thoroughness and user search response time according to current system conditions.
3Productivity
If the LoM queue processes requests continuously, then productivity is maximized, but bottlenecks occur at the LDAP master
Solution Approach 1:
The patent applies periodic action to eliminate processing bottlenecks while maintaining productivity. The LoM queue processes requests in controlled intervals rather than continuously, allowing the LDAP master to keep pace without being overwhelmed. The health metrics engine calculates optimal pause intervals that prevent queue buildup and bottlenecks while maintaining high throughput.
Solution Approach 2:
The patent uses feedback from the health metrics engine to dynamically control LoM queue processing pace. The engine monitors queue depth, update flow, and system resources to adjust processing intervals in real-time. This feedback mechanism ensures the queue processes requests efficiently without creating bottlenecks at the LDAP master, optimizing both productivity and system health.
Data Source
AI summary
A system and method for controlling rates for a Lightweight Directory Access Protocol (LDAP) over MQSeries (LoM) server. The system includes a health metrics engine that calculates an actual delay value, a LoM server that asynchronously obtains the actual delay value from the health metrics engine and place the delay value between one or more requests, and a LDAP master that accepts the one or more requests and send information in the one or more requests to a LDAP replica.
