Optical Network RDMA Path Setup for Faster Communication Start
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computing systems connected via an optical network, the time required to establish RDMA communication paths is prolonged due to the sequential setup of main signal and RDMA communication paths, which delays the initiation of RDMA communication.
Innovation Solution
A communication system with a control communication path and a main signal communication path, where setting requests for both paths are integrated and transmitted via the control path, allowing simultaneous setup of both paths, thereby reducing the time needed for RDMA communication initiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the main signal communication path is established first followed by the RDMA communication path in sequential order, then the communication paths are properly established with correct layering, but the time required to start RDMA communication is prolonged
Solution Approach 1:
The patent applies preliminary action by establishing the RDMA communication path in advance before the main signal communication path is fully set up. The control unit configures the RDMA path at the upper layer first, then subsequently establishes the main signal path at the lower layer. This reverses the conventional sequence and allows RDMA communication to be ready earlier, reducing the time loss while maintaining proper layering through coordinated setup procedures.
2Adaptability or versatility
If the communication path setup is performed dynamically in response to user requests, then the system is flexible and adaptive, but it takes time before RDMA communication becomes possible
Solution Approach 1:
The patent implements preliminary action by pre-configuring the RDMA communication path at the upper layer before the main signal path establishment is completed. When a user request arrives, the control unit has already prepared the RDMA path settings, so communication can start immediately once the main signal path is ready, thereby improving productivity while maintaining dynamic adaptability.
Solution Approach 2:
The patent applies dynamics by making the path setup sequence flexible and adaptive to user requests. The control unit dynamically adjusts the establishment order based on incoming requests, allowing the system to maintain versatility while reducing initiation time through optimized sequencing of path configuration operations.

AI summary
A communication system includes a plurality of computing machines 1 and 2 connected to an optical network, in which the optical network includes a main signal communication path 4 and a control communication path 3. Each of the computing machines 1 and 2 includes a control unit 14 that sets a remote direct memory access (RDMA) communication path, and a communication unit 11 that transmits a setting request including setting information of the RDMA communication path set by the control unit 14 and setting information for setting the main signal communication path 4 to a computing machine of an access destination via the control communication path 3; and a main signal transmitting/receiving unit 16 that establishes the main signal communication path 4 based on the setting information of the main signal communication path 4.
