Relay Server Cross-LAN Resource Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing relay communication systems face challenges in allowing terminals connected to different local area networks (LANs) to share and operate resources dynamically, especially when managed under different protocols, and struggle with flexibility and expandability over wide area networks (WANs.
Innovation Solution
A relay server system that includes account information, relay group information, and shared resource information registration units, enabling terminals to operate resources across different LANs by relaying operation commands through interconnected relay servers, and managing log information for resource operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a virtual network is constructed using packet transmission through multiple LANs, then communication between different LANs is enabled, but it becomes difficult to grasp information on resource deletion or movement as a whole
Solution Approach 1:
The patent introduces a relay server as an intermediary component that collects and manages resource status information from multiple LANs. The relay server acts as a central mediator that receives notifications about resource creation, deletion, and movement from various LANs and maintains a unified view of resource status across the entire network, solving the information fragmentation problem in virtual network constructions
2Ease of operation
If resources are managed under the same protocol within a LAN, then resource sharing is simple, but extending resource sharing across multiple LANs with different protocols becomes difficult
Solution Approach 1:
The patent implements a universal resource management system where the relay server provides protocol-independent resource sharing capabilities. The system allows resources managed under different protocols in various LANs to be shared across the wide area network by translating and standardizing resource access operations, enabling both simple local sharing and complex cross-LAN sharing through a single unified mechanism
3Adaptability or versatility
If a relay server system is implemented to enable resource sharing across different LANs, then resource accessibility is improved, but system complexity increases
Solution Approach 1:
The relay server serves as a centralized intermediary that absorbs system complexity, allowing client terminals to access resources across different LANs without needing complex local configurations. The relay server handles protocol translations, resource location resolution, and access coordination, thereby simplifying the client-side implementation while enabling sophisticated cross-LAN resource sharing

AI summary
A relay communication system includes a relay server R that can communicate with a relay server R in another LAN through an external server S in a WAN. The relay server R stores account information of client terminals T in the LAN, relay group information 100 on a group of relay servers R, and shared resource information 120 including a resource and accounts of the client terminals T sharing the resource. When receiving an operation command of a resource held by a client terminal T in a different LAN from a client terminal T in the LAN, the relay server R relays an operation of the resource on the basis of the relay group information 100 and the shared resource information 120.
