Shared Byte Cache Synchronization via Proxy Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing caching systems in branch offices require complex inter-client machine communication and increased network traffic to achieve shared byte cache functionality, leading to inefficiencies in content distribution and bandwidth usage.
Innovation Solution
Implementing a dedicated shared byte cache system where client systems synchronize their personal byte caches with a centralized cache, using a proxy server to manage content transfer and storage, allowing clients to access a shared cache without redundant data storage and reducing network traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If client systems use personal byte caches independently, then data privacy is maintained, but network traffic increases and bandwidth is wasted due to redundant content transfers
Solution Approach 1:
The patent combines multiple personal byte caches into a unified shared byte cache accessible by all client systems. The shared cache consolidates content storage at the gateway, allowing multiple clients to access the same cached content without requiring separate personal caches, thereby reducing redundant network traffic and bandwidth consumption while maintaining a manageable system structure through centralized control.
2Device complexity
If a shared byte cache is implemented without client communication, then system complexity is reduced, but cache synchronization becomes difficult
Solution Approach 1:
The gateway acts as an intermediary between client systems and the shared byte cache. It receives content from content servers, stores it in the shared cache, and manages client access requests. This intermediary role eliminates the need for direct inter-client communication while ensuring reliable cache synchronization, as the gateway centrally controls what content is cached and makes it available to all authorized clients.
3Speed
If content is cached at each client system, then access speed is improved, but server load increases and data distribution becomes inefficient
Solution Approach 1:
The patent shifts the caching dimension from individual client systems to a centralized shared cache at the gateway. Instead of distributing content copies to multiple clients (horizontal distribution), the system creates a single centralized cache repository that all clients can access efficiently. This dimensional shift maintains fast access speeds through local gateway caching while dramatically improving distribution efficiency by eliminating redundant content transfers across the network.

AI summary
The present invention relates to methods, apparatus, and systems for providing peer-to-peer network acceleration. The system includes a content server configured to transfer content based on received requests for content. The system further includes a proxy server coupled with the content server. The proxy server is configured to receive content from the content server and to forward the received content. Furthermore, the system includes client systems coupled with the proxy server. The client systems each include a personal byte cache and are configured to receive content from the proxy server, to store content in the personal byte caches, to synchronize the personal byte caches with each of the plurality of client system's portions of a shared byte cache, and to retrieve content from the shared byte cache.
