Abstract: Disclosed herein are a method and apparatus for accelerating network transmission in a memory-disaggregated environment. The method for accelerating network transmission in a memory-disaggregated environment includes copying transmission data to a transmission buffer of the computing node, when a page fault occurs during copy of the transmission data, identifying a location at which the transmission data is stored, setting a node in which a largest amount of transmission data is stored as a transmission node, and sending a transmission command to the transmission node.

Abstract: Disclosed herein is a method for memory management in a memory disaggregation environment. The method includes generating virtual memory based on multiple first memory devices, determining whether a condition for allocation acceleration is satisfied by the first memory devices, and allocating a memory page to the first memory devices based on whether the condition for allocation acceleration is satisfied.

Abstract: Disclosed herein is an apparatus for managing disaggregated memory, which is located in a virtual machine in a physical node. The apparatus is configured to select, depending on the proportion of valid pages, direct transfer between remote memory units or indirect transfer via local memory for each of the memory pages of the source remote memory to be migrated, among at least one remote memory unit used by the virtual machine, to transfer the memory pages of the source remote memory to target remote memory based on the direct transfer or the indirect transfer, and to release the source remote memory.

Abstract: Disclosed herein are a method and apparatus for verifying integrity in a memory-disaggregated environment. The method for verifying integrity in a memory-disaggregated environment includes receiving write data and multiple hash values generated based on write data from a remote memory, and verifying integrity of the write data based on the write data and the hash values, wherein verifying the integrity of the write data comprises selecting a hash value for the integrity verification based on an access latency of the remote memory.
