Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face challenges in simplifying control while enhancing reliability, particularly in aggregating networks and providing redundancy, as aggregation and redundancy require different configurations, making it difficult to combine them effectively.
Innovation Solution
A communication control apparatus and system that includes a communication control unit, topology conversion information storage unit, and topology update unit, which converts notifications and flow settings between aggregated and real networks, allowing dynamic control and redundancy management by storing connection relationships and updating topology information to convert aggregated flows into real flows for each core node.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If network aggregation is implemented to simplify control, then control complexity is reduced, but reliability and redundancy capabilities deteriorate
Solution Approach 1:
The patent introduces an aggregation apparatus as an intermediary device between core nodes and the control apparatus. This aggregator translates and converts control messages, allowing simplified control while maintaining the underlying complex redundant network structure. The intermediary handles the complexity of mapping aggregated flows to real flows, preserving reliability without exposing control complexity.
2Reliability
If redundancy is provided through multiple independent networks, then reliability is enhanced, but control complexity increases
Solution Approach 1:
The patent merges multiple core nodes into a single aggregated network view, combining their control interfaces. The aggregation apparatus consolidates control messages for multiple nodes into unified flow settings, reducing control complexity while maintaining the redundant network structure for reliability.
3Adaptability or versatility
If aggregation apparatus translates control messages, then compatibility between aggregated and real networks is improved, but processing complexity increases
Solution Approach 1:
The aggregation apparatus changes parameters of control messages during translation, converting between aggregated network parameters and real network parameters. It modifies flow identifiers, port mappings, and node identifiers to maintain compatibility across different network layers while managing processing complexity through systematic parameter transformation.

AI summary
A communication control apparatus according to the present invention is connected between a core node which processes received packets in accordance with a specified flow and a control apparatus which controls the core node, controls each of the core nodes existing in an aggregated network into which one or more the core nodes are aggregated, and converts an aggregated flow specified for an aggregated network and received from the control apparatus to a real flow specified for each of the core nodes in the aggregated network based on connection relationships between the core nodes in the aggregated network, information specifying a real port which is a port through which the core node in the aggregated network is connected to a device outside the aggregated network and a real node which is the core node having the real port for each the aggregated networks.
