Dual Cache System for Contextual Address Space Resource Caching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing caching strategies in resource-oriented computing systems face challenges in optimizing context resolution and minimizing cache memory space while maintaining efficient lookup times, particularly in dynamic and multivalent contextual address spaces.
Innovation Solution
Implementing a caching strategy that systematically optimizes context resolution and physical endpoint computation costs by using a cache that tracks the scope of the contextual address space, with a dual cache system (Resolution Cache and Representation Cache) to store and retrieve resource representations efficiently, and employing a mapping function to associate cache entries with request scope keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a comprehensive cache stores all resource representations with full context information, then lookup efficiency is improved, but cache memory space requirements increase
Solution Approach 1:
The cache system is divided into two separate caches: a resolution cache that stores context resolution information (request scope keys mapped to endpoints) and a representation cache that stores resource representations. This segmentation allows each cache to be optimized for its specific purpose, reducing the total memory footprint while maintaining efficient lookup times for both resolution and representation retrieval.
Solution Approach 2:
The patent extracts and caches only the essential key elements (request scope keys and their mappings to endpoints) in the resolution cache, rather than storing complete context information. This extraction of critical path information enables efficient resolution lookups without the overhead of storing full contextual data, thereby reducing cache memory requirements while preserving lookup efficiency.
2Measurement precision
If the cache tracks the scope of contextual address space, then context resolution accuracy is improved, but device complexity increases
Solution Approach 1:
The request scope key serves multiple functions: it uniquely identifies a context scope, encodes the hierarchical structure of the address space, and acts as a cache key for both resolution and representation lookups. This multi-functionality allows the system to maintain accurate context resolution without adding separate tracking mechanisms, thereby avoiding increased device complexity while preserving resolution precision.
3Productivity
If a dual cache system is implemented to store both resolution and representation data, then overall system efficiency is improved, but device complexity increases
Solution Approach 1:
The resolution cache and representation cache are managed as an integrated dual-cache system with a unified interface and coordinated lookup process. The resolution cache provides endpoint information that directly leads to the representation cache, creating a streamlined two-stage retrieval process. This merging approach improves overall system efficiency by optimizing each cache for its specific data type while maintaining a cohesive architecture that avoids the complexity of multiple independent caching systems.

AI summary
A method to generate and save a resource representation recited by a request encoded in a computer algorithm, wherein the method receives from a requesting algorithm an Unresolved resource request. The method resolves the resource request to an endpoint and evaluates the resolved resource request by the endpoint to generate a resource representation. The method further generates and saves in a cache at least one Unresolved request scope key, a resolved request scope key, and a cache entry comprising the resource representation. The method associates the cache entry with the resolved request scope key and with the at least one Unresolved request scope key using a mapping function encoded in the cache.
