Abstract

The present disclosure provides a method, device, and system for processing a request in a multi-core system. The method comprises steps of: receiving a request for data by a filter from a requesting unit; comparing an indicator indicative of a logical partition in the request with an indicator indicative of the logical partition in a record of the filter; searching in a unit where the filter is located based on the request and returning a search result to the requesting unit if a comparison result matches; and returning a NONE response to the requesting unit from the filter if the comparison result does not match.
