Title:
FILECOIN CLUSTER DATA TRANSMISSION METHOD AND SYSTEM BASED ON REMOTE DIRECT MEMORY ACCESS
Document Type and Number:
WIPO Patent Application WO/2023/019800
Kind Code:
A1
Abstract:
The present application provides a filecoin cluster data transmission method and system based on remote direct memory access (RDMA). The method comprises the following steps: configuring a RDMA protocol-based RDMA interface at a data transmission interface of a filecoin cluster; a first encapsulation node receives sector data sent by a customer for encapsulation, and invokes the RDMA interface after the encapsulation is completed to serially send the sector data to the next encapsulation node for encapsulation; upon receipt of the sector data sent by the previous encapsulation node, an HCA card of the last encapsulation node invokes the RDMA interface to directly send the sector data to a user-state memory of the encapsulation node for encapsulation, invokes the RDMA interface after the encapsulation is completed to serially send the sector data completed encapsulated back to the HCA card of the last encapsulation node, and sends the sector data to distributed storage by means of the HCA card. The RDMA interface is used to perform data transmission, multiple memory replications are not required, and the data transmission efficiency is improved.
