Existing RDMA communication systems struggle to dynamically adjust the number of optical transmission paths, leading to delays in setting up RDMA communication paths in response to user requests.

Innovation Solution

A communication system with computing machines equipped with an optical transmission path control unit to adjust and set the number of optical transmission paths, an RDMA communication unit to chunk data according to these paths, and an RDMA control unit to match the number of RDMA communication paths, facilitating easy and efficient setup.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If RDMA communication is set dynamically in response to user requests, then communication responsiveness is improved, but setup time increases due to difficulty in recognizing and automatically setting optical transmission paths

Engineering Contradiction:

ImproveRDMA communication setupVSAvoidRDMA communication setup time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent implements feedback mechanisms where the optical transmission path control unit continuously monitors and reports the number of available optical transmission paths to the RDMA communication unit. This feedback loop enables the system to automatically adjust RDMA communication settings based on real-time optical path availability, eliminating manual configuration delays while maintaining responsive communication setup.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system enables self-service automation where the RDMA communication unit automatically configures communication paths based on reports from the optical transmission path control unit. The computing machines autonomously recognize the number of optical transmission paths and set RDMA communication parameters without external intervention, reducing both manual operation requirements and setup time.

Inventive Principle:

Principle #25Self-service

2Productivity

If the number of optical transmission paths is increased to enhance communication capacity, then data transfer speed is improved, but system complexity increases due to difficulty in managing and coordinating multiple paths

Engineering Contradiction:

Improvecommunication capacityVSAvoidoptical transmission path management

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent creates a universal control architecture where the optical transmission path control unit and RDMA communication unit work together through standardized interfaces and protocols. This multi-functional system can manage any number of optical transmission paths using the same control mechanisms, enabling the system to scale from single-path to multi-path configurations without proportionally increasing management complexity.
