MEMORY EXPANSION METHOD AND RELATED DEVICE

This application discloses a memory expansion method and a related device. A first network device may generate a memory topology based on memory requirement information of a target application and usage of a memory resource in a first memory pool, and then establish a second memory pool in the first memory pool based on the memory topology, where the second memory pool indicates a memory resource that is allowed to be used by the target application. In this way, the first network device can appropriately allocate a memory to the target application based on the memory requirement information and the usage of the resource in the first memory pool, and dynamically adjust service load distribution between the memory pools, so that service load of the memory pools is appropriately distributed, waiting time for a cluster operation is reduced, and operation efficiency is improved.
