Solution Overview

Problem

Current computer network caching systems do not effectively differentiate between static and dynamic content, leading to inefficient bandwidth usage and increased load times, as they lack a mechanism to selectively store and serve these content types separately.

Innovation Solution

Implementing a method within a network gateway to analyze incoming content messages and selectively store static content in a cache, allowing dynamic content to be served directly from the web server, while static content is cached for faster retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If all content is stored in the cache, then bandwidth usage is reduced, but cache memory is wasted on dynamic content that changes frequently

Engineering Contradiction:
Improvebandwidth usageVSAvoidcache memory utilization
Core Design Contradiction:
Loss of energyVSQuantity of substance

Solution Approach 1:

The system applies different caching strategies to different content types by analyzing content characteristics (static vs. dynamic). Static content is cached to reduce bandwidth usage, while dynamic content is served directly from the server. This local differentiation optimizes both bandwidth efficiency and cache memory utilization.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system changes the caching parameter (store vs. don't store) based on content characteristics. By analyzing content properties such as file type, modification frequency, and content structure, the system dynamically determines whether to cache each piece of content, optimizing the balance between bandwidth savings and cache memory efficiency.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If content is analyzed to determine if it is static, then caching efficiency is improved, but processing time increases

Engineering Contradiction:
Improvecaching efficiencyVSAvoidprocessing time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs partial analysis of content characteristics rather than complete analysis. By checking key indicators such as file extensions, content length, and modification patterns, the system makes caching decisions without fully processing every aspect of the content, thus balancing accuracy with processing time.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system performs content analysis in advance before serving the content to the client. By pre-determining whether content is static or dynamic and making caching decisions beforehand, the system avoids processing delays during content delivery and improves overall response time.

Inventive Principle:
Principle #10Preliminary action

3Loss of time

If static content is served from cache, then load time is reduced, but cache hit ratio decreases if content is misclassified as dynamic

Engineering Contradiction:
Improveload timeVSAvoidcache hit ratio
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The system uses feedback mechanisms to verify content classification accuracy. By monitoring cache performance metrics and content access patterns, the system can adjust its classification algorithms to improve accuracy in distinguishing static from dynamic content, thereby reducing misclassification errors.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system replaces simple mechanical caching rules with intelligent content analysis mechanisms. Instead of using fixed caching policies, the system employs content characteristic analysis, machine learning models, or heuristic algorithms to dynamically determine cachability, improving both speed and accuracy of content classification.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

At a gateway within a network, a message containing content is received. The message conforms to a protocol that specifies a format of the content, the message having been sent from a server outside the network to a client within the network. The message is routed from the gateway to the client. The message is analyzed to determine whether the content is static. Depending on a result of the analyzing, the content is selectively caused to be stored in the format specified by the protocol in a cache within the network.
