Presence Server Resource Sharing System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems, such as instant messaging and presence-based technologies, are complex for users to operate, especially when sharing data files privately, requiring high technical expertise and lacking user-friendliness in facilitating resource sharing between individuals.
Innovation Solution
A resource sharing system comprising a host element, a shareable resource, a presence server, and a resource proxy server, which provides presence information and enables selective authorization and sharing of resources through a communicatively coupled network, allowing users to easily share resources like webcams, music files, or documents within their buddy lists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If presence-based technologies are used for resource sharing, then users can share resources like webcams, music files, or documents, but the system becomes complex to operate and requires high technical expertise
Solution Approach 1:
The patent introduces a presence server as an intermediary component that mediates between users and shared resources. The presence server manages presence information, handles authorization requests, and coordinates resource sharing operations, thereby simplifying the user interface and reducing operational complexity while maintaining versatile resource sharing capabilities
2Reliability
If private file exchange is implemented in IM systems, then users can share data files privately, but the operational complexity increases significantly
Solution Approach 1:
The presence server performs multiple functions including presence information management, authorization handling, and resource sharing coordination. By consolidating these functions into a single multi-functional server, the system achieves reliable private file exchange without proportionally increasing overall system complexity
3Productivity
If concurrent IM messaging and data transfer are enabled, then users can communicate and share files simultaneously, but firewall traversal becomes more difficult
Solution Approach 1:
The presence server acts as a trusted intermediary that both parties can communicate through. By routing concurrent IM messaging and data transfer operations through this centralized server, the system maintains firewall compatibility while enabling simultaneous communication and file transfer, as the server handles connection management and protocol coordination
Data Source
AI summary
In a resource-sharing system comprising a host element, a shareable resource associated with the host element, and a presence server that is communicatively coupled to the host element, presence information of the shareable resource is provided. Resource data from the host element is provided to a guest element via a resource proxy server.
