Relay Server File Sharing via Segmented Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for file transmission, such as email and FTP, are cumbersome and costly, requiring complex setup and separate management of files and messages, leading to inefficient information management across distributed networks.
Innovation Solution
A relay server configuration with account, relay group, and shared resource information units enables seamless file sharing and messaging across client terminals, integrating resource and message management through a relay communication system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If email with attachment is used for file transmission, then files can be sent with messages, but file management becomes cumbersome and mailbox size limitations require compression or division
Solution Approach 1:
The patent segments file transmission from message transmission by introducing a dedicated file transfer protocol layer. Files are transmitted as separate data packets with associated metadata, while messages are transmitted through the email system. This separation eliminates the need to manage file attachments within mailbox constraints.
Solution Approach 2:
The patent introduces a file transfer server as an intermediary between clients. The server handles file storage, retrieval, and transmission independently of the email system. Clients interact with the server through a standardized protocol, eliminating direct file attachment management and mailbox size limitations.
2Productivity
If FTP service is used for large file transmission, then large files can be transmitted efficiently, but account setup and service configuration become troublesome
Solution Approach 1:
The patent creates a universal file transfer protocol that works across different platforms and networks without requiring platform-specific FTP accounts. The protocol handles authentication, file transfer, and message transmission in a unified manner, eliminating the need for separate FTP service setup while maintaining efficient large file transmission capabilities.
3Reliability
If separate methods are used for file transmission and message transmission, then each can be optimized independently, but additional troublesome work is required and information management becomes complex
Solution Approach 1:
The patent merges file transfer and message transmission into a unified communication framework. Both functions operate through the same protocol layer and share common infrastructure including authentication, session management, and error handling. This integration reduces operational complexity while maintaining the reliability benefits of specialized transmission methods.
Data Source
AI summary
A relay server stores registered terminal information and information about the relay servers that form a relay group permitting connection among each other, about a shared resource, about terminals sharing the resource, and about a message to be transmitted in association with the resource. When an operation instruction regarding the resource held by another terminal is received from the registered terminal to which the relay server is connected, the relay server relays the operation instruction to another relay server. When the message is transmitted to the other terminal by the terminal, message information is relayed.
