Heterogeneous Network Path Selection Using Transmission Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current path selection mechanisms, such as distance vector and link state algorithms, are ineffective in heterogeneous network systems due to diverse communication standards among network apparatuses, leading to complex dynamic link relationships and inability to find the most appropriate transmission path.
Innovation Solution
A network apparatus measures local and global transmission parameters, enumerates paths to a target apparatus, and calculates path costs by combining these parameters to select the most appropriate transmission path, utilizing sub-parameters with weight values for accurate path determination.

Engineering Contradiction Analysis
1Ease of operation
If distance vector algorithm or link state algorithm is adopted for path selection in heterogeneous network system, then path selection mechanism is established, but it is impossible to get the most appropriate path with lowest cost due to complex dynamic link relationships
Solution Approach 1:
The patent changes the parameters used for path selection from traditional routing metrics to transmission parameters including transmission speed, error rate, and latency specific to each interface type (PLC, Wi-Fi, Ethernet, MoCA). This allows accurate cost calculation for heterogeneous paths by evaluating actual transmission characteristics rather than relying on generic routing algorithms that cannot adapt to diverse interface properties
Solution Approach 2:
The patent implements dynamic path selection by continuously monitoring transmission parameters and updating path costs in real-time. When network topology changes or transmission conditions vary, the system recalculates path costs based on current transmission parameter values, enabling adaptive selection of the most appropriate path rather than static routing decisions
2Adaptability or versatility
If traditional path selection mechanisms are used in homogeneous network system, then path selection is straightforward, but these mechanisms cannot be applied to heterogeneous network systems with diverse communication standards
Solution Approach 1:
The patent creates a universal path selection mechanism that works across all interface types (PLC, Wi-Fi, Ethernet, MoCA) by defining a common framework for measuring and evaluating transmission parameters. The system maintains a transmission parameter database that stores characteristics for all interface types and applies unified cost calculation methods, enabling single apparatus to handle heterogeneous network paths without requiring interface-specific routing logic
Solution Approach 2:
The patent introduces transmission parameter databases and measurement mechanisms as intermediaries between diverse interface types and the path selection logic. These intermediaries standardize the representation of different interface characteristics, translating various communication standards into comparable transmission parameters that can be evaluated uniformly by the path cost calculation system
3Productivity
If network apparatus joins or leaves heterogeneous network system, then network topology changes, but this causes significant changes in link relationships making path selection difficult
Solution Approach 1:
The patent implements feedback mechanisms where network apparatus continuously measure and report transmission parameters to the path selection system. When topology changes occur (apparatus joining or leaving), the system receives updated transmission parameter information and automatically recalculates path costs, providing continuous feedback-driven adaptation without requiring manual reconfiguration or complex topology management protocols
