Local Resource Delivery Network for LAN Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote network storage solutions often require users to retrieve resources from a remote storage provider even when those resources are available locally within the same local area network (LAN), leading to inefficiencies and unnecessary data transfer.
Innovation Solution
A system where a user computing device within a LAN detects the availability of requested resources on other connected devices within the LAN and retrieves them locally instead of from a remote storage provider, using a resource manager client and server to manage metadata and facilitate local resource sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If resources are retrieved from remote network storage provider, then resource availability across multiple devices is ensured, but data transfer efficiency deteriorates and unnecessary bandwidth consumption occurs when resources are available locally
Solution Approach 1:
The patent introduces a LAN intermediary system that mediates between the client device and remote storage provider. When a resource request is made, the intermediary first checks local LAN devices for available copies before contacting the remote provider, thus reducing unnecessary remote data transfers and bandwidth consumption while maintaining resource availability.
Solution Approach 2:
The system performs preliminary actions by proactively detecting and caching resource metadata and availability information from the LAN before actual resource requests occur. This preliminary detection enables the system to quickly identify local resources and avoid remote transfers, improving retrieval efficiency and reducing bandwidth usage.
2Ease of operation
If remote network storage is used for all resources, then centralized storage management is achieved, but system complexity increases due to constant remote communication requirements
Solution Approach 1:
The patent segments the storage system into three distinct layers: local device storage, LAN shared storage, and remote cloud storage. Each layer handles specific types of resources based on access frequency and importance, reducing the need for constant remote communication while maintaining centralized management capabilities through the resource manager that coordinates across all segments.
Solution Approach 2:
The system applies local quality by enabling each LAN device to maintain local copies of frequently accessed resources, giving local priority to commonly used files. This creates a hierarchical quality structure where local resources receive preferential treatment for speed, while remote storage provides backup capacity, simplifying the overall system by reducing remote communication overhead.
3Speed
If local storage is used for frequently accessed resources, then access speed improves, but storage capacity limitation becomes a constraint
Solution Approach 1:
The patent implements a nested storage architecture where local device storage contains frequently accessed resources, which are nested within the broader LAN storage network, which in turn is nested within the remote cloud storage system. This nested structure allows the system to exploit the speed of local storage for hot data while offloading less frequently accessed data to larger remote storage capacities, effectively combining speed and capacity advantages.
Solution Approach 2:
The system transitions from a single-dimension local storage model to a multi-dimensional storage hierarchy spanning local devices, LAN network, and remote cloud. This dimensional expansion allows resources to be distributed across multiple storage tiers, enabling the system to maintain fast local access for critical data while utilizing the vast capacity of remote storage for archival and backup purposes.
Data Source
AI summary
A local area network (LAN) may contain several local computing devices that are in communication with a remote network storage provider that is not part of the LAN. Resources may be available from the remote network storage provider. When a user requests a resource using a first local computing device in the LAN, the first local computing device may check the other local computing devices on that are in the LAN for the resource before requesting the resource from the remote network storage provider. If the resource is available within the LAN, the resource is not requested from the remote network storage provider.
