Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If many communication paths are simultaneously used in aggregation communication, then transmission capacity is increased, but a flow cannot be distributed to a suitable communication path
Solution Approach 1:
The patent implements dynamic flow distribution by continuously monitoring bandwidth availability on multiple communication paths and redistributing flows based on real-time conditions. The distribution control unit dynamically determines which path to assign each flow to, adapting to changing network conditions rather than using static routing, thus maintaining ease of operation while utilizing multiple paths for increased capacity.
Solution Approach 2:
The patent changes the parameter of bandwidth availability as the key criterion for flow distribution. By monitoring and comparing bandwidth parameters across different communication paths, the system intelligently assigns flows to paths with sufficient available bandwidth, resolving the contradiction between using many paths for capacity and ensuring proper flow distribution.
2Device complexity
If flows are distributed based on fixed routing, then path assignment is simple, but transmission capacity cannot be fully utilized
Solution Approach 1:
The patent introduces feedback mechanisms where transmission apparatuses report current available bandwidth information to the distribution control unit. This feedback loop enables the system to monitor actual path conditions and adjust flow distribution accordingly, increasing transmission capacity utilization while maintaining manageable complexity through automated control.
Solution Approach 2:
The system performs preliminary bandwidth measurement and availability assessment before assigning flows to communication paths. By evaluating bandwidth conditions in advance and storing this information for future distribution decisions, the system optimizes capacity utilization without requiring complex real-time calculations during flow assignment.
3Ease of operation
If real-time bandwidth monitoring is implemented, then flow distribution is optimized, but system complexity increases
Solution Approach 1:
The patent implements self-service by having transmission apparatuses automatically monitor and report their own bandwidth availability to the distribution control unit. This self-monitoring capability eliminates the need for complex centralized monitoring systems, optimizing flow distribution while keeping system complexity manageable through distributed self-reporting rather than centralized control.

AI summary
In a communication apparatus (10), a determination unit (12) determines, from a plurality of candidate communication paths other than one of a plurality of communication paths used for multilink communication, a distribution-destination communication path based on the free bandwidths of the respective candidate communication paths. Further, a distribution control unit (11) executes control for distributing a setting flow for the one communication path to the determined distribution-destination communication path.
