Abstract

The embodiment of the invention provides a data access method, device and system, electronic equipment and a computer readable medium, and relates to the field of data access. The method comprises thefollowing steps: an RDMA management and control service allocates an address field to a first instance based on user information and a corresponding connection relationship between the first instancedefined by a user and a switch; the RDMA management and control service constructs an access control list based on the address fields allocated to the first instances, and the access control list isused for controlling access between different first instances defined by a user; and the RDMA management and control service sends the access control list to the switch management and control service,so that the switch management and control service configures the access control list for the switch. According to the embodiment of the invention, the access among different instances defined by thesame user can be effectively controlled, so that the problem of access isolation of different users accessing the RDMA network node is effectively solved.

Description

technical field [0001] The embodiments of the present application relate to the field of data access, and in particular to a data access method, device, system, electronic equipment, and computer-readable medium. Background technique [0002] The DCB (Data Center Bridge, Data Center Bridge) network based on RoCE (RDMA over Converged Ethernet, RDMA protocol based on enhanced Ethernet) is based on an enhanced Ethernet protocol, which guarantees data on the link through priority and flow control. layers of reliable transport. [0003] The RDMA message based on RoCEv2 (the second version of RoCE) is embedded in the UDP (User Datagram Protocol, User Datagram Protocol) protocol message, and the UDP protocol relies on the TCP / IP protocol for routing. Since the TCP / IP protocol serves the general public, the RoCE-based switching infrastructure may be used by different customers. Therefore, to provide RoCE-based RDMA communication functions on public cloud instances, it is necessary ...
