A network device is configured to transmit an outgoing packet to another network device. The outgoing packet is a Quick User Datagram Protocol Internet Connection (QUIC)-based packet, which comprises a User Datagram Protocol (UDP) header, a QUIC header, and a QUIC payload. The UDP header comprises an indication that the QUIC payload comprises one or more RDMA transactions. The QUIC payload comprises the one or more RDMA transactions.

Device and method for romote direct memory access

A method and apparatus are described. The method comprises receiving a data packet comprising data to be written into the memory of a computing system and address data comprising an address in a set of addresses of a first address space of the computing system, identifying a subset of the set of addresses of the first address space with a subset of addresses in a second address space associated with the memory of the computing system, determining an address from a further subset of addresses in the second address space, writing the data to the region of the memory associated with the determined address and updating an address translation table on the computing system on the basis of the determined address.

Method and system for direct memory access

A computing system receives a data packet comprising data to be written to the computing system and address data comprising an address in a set of addresses of a first address space of the computing system. An address is determined in a second address space of the computing system identified with the address of the data packet and writing the data to the computing system on the basis of the determination. A first subset and a second subset of the set is identified and the first subset of addresses of the second address space is associated with a region of memory of the computing system and the second subset of addresses of the second address space is associated with a region of a data storage area.

The present disclosure provides devices and methods relating to remote direct memory access (RDMA). In one implementation, a target device of the RDMA operation is configured to receive a packet including a first destination address and a destination key, obtain one or more offset values, and obtain a second destination address based on the first destination address, the destination key, and the one or more offset values. Further, the target device is configured to initiate the RDMA operation on a memory based on the second destination address.
