Access method and device of multi-level cache system, electronic equipment and storage medium

The invention provides an access method and device for a multi-level cache system, electronic equipment and a storage medium, and the method comprises the steps: judging whether a first child node, storing a target data block, of a request processor core is recognized or not before an access request sent by the request processor core reaches a main node to which the target data block belongs; in response to the fact that the first sub-node is not recognized, obtaining a first distance from the request processor core to the second sub-node, obtaining a second distance from the request processor core to the main node, and determining a target processing object from the second sub-node and the main node based on the first distance and the second distance; and processing the access request through the target processing object. By determining the first distance and the second distance, the target processing object with the better transmission effect is selected from the second child node and the main node to proce
