Dynamic Communication Path Selection for Multihomed Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multihomed networks face challenges in dynamically distributing communication loads across multiple paths to optimize communication quality and reliability, as existing systems lack efficient methods to assess and adapt to varying communication path conditions in real-time.
Innovation Solution
A communication apparatus with a determination portion that evaluates communication path qualities based on measured parameters like throughput, round trip time, and data loss rate, dynamically selecting the most suitable path for data transmission based on the characteristics of the data being sent, using interface communication apparatuses and data distributing communication devices to manage and reroute data effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple communication paths are used for data transmission, then communication reliability is improved, but communication quality optimization becomes difficult due to lack of dynamic path selection capability
Solution Approach 1:
The patent implements dynamic communication path selection by continuously monitoring communication qualities (throughput, round trip time, data loss rate) of multiple paths and automatically selecting the optimal path based on real-time conditions. This dynamic adaptation resolves the contradiction by enabling the system to maintain high reliability through multiple paths while optimizing communication quality through automated, real-time path selection.
Solution Approach 2:
The system employs feedback mechanisms by measuring communication qualities on each path and using this information to make informed routing decisions. The determination portion receives feedback about path conditions and adjusts path selection accordingly, thereby maintaining reliability while optimizing communication quality without requiring complex manual configuration.
2Productivity
If communication path conditions are monitored in real-time, then communication quality is optimized, but system complexity and measurement overhead increase
Solution Approach 1:
The communication apparatus performs self-measurement of communication qualities using its own resources. The determination portion measures throughput, round trip time, and data loss rate using built-in measurement capabilities, eliminating the need for external monitoring systems and reducing overall system complexity while maintaining real-time optimization.
Solution Approach 2:
The system measures only the essential communication quality parameters (throughput, round trip time, data loss rate) needed for effective path selection, rather than monitoring all possible network metrics. This partial measurement approach achieves communication quality optimization without the overhead of comprehensive system monitoring.
3Reliability
If data is transmitted over the best available path, then communication quality improves, but the system requires sophisticated path evaluation and selection mechanisms
Solution Approach 1:
The determination portion automatically evaluates communication paths and selects the optimal one without requiring manual intervention or complex configuration by operators. The system self-manages path selection based on measured qualities, improving reliability while maintaining ease of operation through automated decision-making.
Solution Approach 2:
The determination portion acts as an intermediary between multiple communication paths and the data transmission process. It evaluates path qualities and makes routing decisions, thereby improving data transmission reliability while shielding users from the complexity of path management through automated mediation.
