Remote Data Access Method and Apparatus - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240348686 titled 'Remote Data Access Method and Apparatus
The abstract describes a method for remote data access between two devices, each equipped with a Network Interface Card (NIC) with Remote Direct Memory Access (RDMA) functionality. The method involves generating a packet with a type identifier and a function identifier, sending it to the second device, and instructing the second device to perform a specific operation on its local data based on the function identifier.
- The method involves utilizing NICs with RDMA functionality in both devices.
- A packet is generated with a type identifier indicating it is a Remote Memory Function Call (RMFC) type packet.
- The packet includes a function identifier specifying the type of operation to be performed on the second device's local data.
- The second device executes the preset operation based on the received packet.
Potential Applications: - High-speed data transfer between devices. - Efficient remote data processing. - Real-time data synchronization.
Problems Solved: - Overcoming latency issues in remote data access. - Improving data transfer speeds between devices.
Benefits: - Faster data access and processing. - Reduced network congestion. - Enhanced overall system performance.
Commercial Applications: Title: "Enhanced Remote Data Access Method for Improved Performance" This technology can be utilized in industries requiring fast and efficient data transfer, such as telecommunications, cloud computing, and high-performance computing.
Questions about Remote Data Access Method: 1. How does the RDMA functionality in NICs improve data transfer speeds? RDMA allows data to be transferred directly between the memory of two devices without involving the CPU, reducing latency and improving efficiency.
2. What are the key advantages of using RMFC-type packets in remote data access? RMFC-type packets streamline the communication process between devices by specifying the type of operation to be performed, leading to faster and more efficient data processing.
Original Abstract Submitted
a remote data access method is applied to a first device that is coupled to and communicates with a second device. the first device and the second device each are configured with a network interface card (nic) having a remote direct memory access (rdma) function. the method is performed by a nic of the first device, and the method includes: generating a first packet including a type identifier and a function identifier; and sending the first packet to the second device. the type identifier in the first packet indicates that the first packet is a remote memory function call (rmfc)-type packet, and the rmfc-type packet indicates the second device to perform a preset operation on local data of the second device. the function identifier in the first packet indicates an operation type of the preset operation.
