Peer-to-Peer Terminal Classification for Fair Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Peer-to-peer networks penalize terminals with limited transmission capacity, leading to disparities in data sharing and potential 'free-rider' issues, as they are not prioritized for receiving digital content due to their lower contribution, despite possible constraints on their transmission capabilities.
Innovation Solution
Assigning a transmission capacity level to each terminal based on its characteristics and the underlying physical network, allowing for weighted decision-making in data sharing, prioritizing terminals with lower capacity and preventing uncontrolled class modifications to ensure accurate representation of capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If peers are prioritized based on their data contribution to the network, then active peers receive digital content preferentially, but terminals with limited transmission capacity are penalized and disadvantaged
Solution Approach 1:
The patent introduces a transmission capacity level parameter that classifies terminals into different categories (e.g., first transmission capacity level and second transmission capacity level). This parameter change enables the system to differentiate treatment based on actual capability rather than just contribution, resolving the contradiction between productivity and fairness.
Solution Approach 2:
The patent applies different prioritization rules to different local groups of terminals based on their transmission capacity levels. Terminals with higher capacity receive different treatment compared to terminals with limited capacity, allowing each local group to be optimized according to its specific characteristics while maintaining overall system fairness.
2Adaptability or versatility
If transmission capacity level is assigned to each terminal, then fair prioritization is achieved, but system complexity increases
Solution Approach 1:
The patent segments terminals into distinct classes based on transmission capacity levels. This segmentation simplifies the management complexity by creating clear categories with specific prioritization rules, rather than requiring continuous or complex individual evaluation of each terminal's capabilities.
Solution Approach 2:
The patent uses standardized transmission capacity level classifications that can be copied and applied consistently across the network. These predefined levels serve as templates for prioritization decisions, reducing the need for complex real-time calculations and enabling straightforward implementation of fair prioritization rules.

AI summary
In a peer-to-peer communication network between terminals, classes are assigned respectively to said terminals, a class indicating the transmission capacity of the terminal. The transmission capacity of a terminal corresponds to at least one transmission characteristic associated with the terminal and depends at least on a type of underlying physical network to which the terminal belongs. At a first terminal, a request is received (21) to transmit digital content to a second terminal, the request indicating the class assigned to the second terminal. Then a decision is made (22) whether or not to transmit at least a portion of the digital content to the second terminal, on the basis of said indicated class. Finally, the decision is transmitted (23) to the second terminal.
