Micro-staging Device Prefetching Data to Reduce Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information handling systems face latency issues due to long round-trip times between mobile user information handling systems and remote data centers, particularly in wireless networks, which affect performance and battery life, as they rely on shared resources and distant data storage.
Innovation Solution
The implementation of micro-staging devices that pre-fetch data based on contextual policies, caching relevant data locally to reduce latency by acting as a local cache between user information handling systems and remote data centers, thereby optimizing communication and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data is stored in remote data centers, then data storage capacity is improved, but latency and response time worsen due to long round-trip times
Solution Approach 1:
The patent segments the centralized data center storage system into distributed micro-staging devices placed at multiple network locations. Each micro-staging device holds a portion of the data, allowing users to access data from the nearest location rather than always communicating with the remote data center, thereby reducing latency while maintaining storage capacity.
Solution Approach 2:
The micro-staging devices act as intermediaries between users and the remote data center. They prefetch and cache data locally, serving as a buffer that reduces the round-trip time for data access while maintaining the ability to store large quantities of data across the distributed system.
2Ease of operation
If mobile users access remote data centers directly, then data access capability is improved, but battery life worsens due to increased 'on-air' time
Solution Approach 1:
The system performs preliminary actions by prefetching data to micro-staging devices before users need it. This advance preparation allows users to access data locally from nearby micro-staging devices rather than maintaining continuous wireless connections to remote data centers, reducing 'on-air' time and energy consumption while preserving data access capability.
3Adaptability or versatility
If wireless networks use shared resources, then network resource utilization is improved, but performance worsens due to latency
Solution Approach 1:
The patent implements local quality by placing micro-staging devices at specific network locations closer to users. These devices provide localized data storage and access, reducing the distance and time for data retrieval while still utilizing shared network resources for data population and management, thereby improving performance without sacrificing resource utilization efficiency.
Data Source
AI summary
A micro-staging device has a wireless interface module for detecting a first data request that indicates a presence of a user and an application processor that establishes a network connection to a remote data center. The micro-staging device further allocates a portion of storage in a cache memory storage device for storing pre-fetched workflow data objects associated with the detected user.
