Traffic Simulation for Content Caching Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service providers face challenges in managing and controlling the delivery of heavy bandwidth-consuming data, such as video, which leads to network degradation and potential failures due to the inability to efficiently share bandwidth and cache popular content effectively.
Innovation Solution
A computerized method and apparatus for generating a traffic simulation to identify content sources and determine if content should be cached, using deep-packet-inspection (DPI) to analyze packets and simulate notifications for storing or delivering content from caches, thereby optimizing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all data is stored in caches to handle heavy bandwidth consuming traffic, then network performance is improved, but device complexity and operational difficulty increase significantly
Solution Approach 1:
The patent changes the parameter of cache management from storing all data to storing only popular content identified through traffic analysis. By monitoring traffic patterns and identifying frequently accessed content, the system dynamically adjusts what to cache based on actual usage parameters, thereby improving network performance without requiring complex infrastructure to cache everything.
Solution Approach 2:
The system implements self-service by automatically analyzing traffic patterns and identifying popular content without manual intervention. The cache management system autonomously determines which content to store and retrieve based on observed usage, eliminating the need for complex manual configuration and reducing operational difficulty.
2Loss of energy
If deep-packet-inspection is used to identify and cache popular content, then bandwidth efficiency is improved, but processing intensity and operational complexity increase
Solution Approach 1:
The patent applies partial action by performing deep-packet-inspection selectively rather than on all traffic. The system inspects packets to identify popular content for caching but does not process every single packet in detail, thereby improving bandwidth efficiency through intelligent caching while avoiding the excessive processing burden of analyzing all network traffic comprehensively.
3Quantity of substance
If content is cached to reduce network traffic, then network load is reduced, but measurement and detection difficulty increases due to need to identify popular content
Solution Approach 1:
The patent implements feedback mechanisms by continuously monitoring network traffic patterns and using this information to identify popular content. The system observes which content is frequently accessed, feeds this information back into the caching decision process, and adjusts cache contents accordingly. This automated feedback loop reduces network traffic effectively while simplifying the detection of popular content through systematic observation rather than complex analysis.
