Abstract
K classifiers and S network service processors are deployed in a network device. A network adapter receiving queue is divided into multiple queue areas. Each classifier may acquire a packet identifier from a queue area that corresponds to the classifier and is in the network adapter receiving queue, that is, the network adapter receiving queue has multiple information reading interfaces such that the K classifiers may concurrently read packet identifiers from corresponding queue areas in the network adapter receiving queue, and the K classifiers may further concurrently determine, based on the packet identifiers acquired by the K classifiers, corresponding flow queue identifiers. Related operations before the K classifiers distribute packet description information to flow queues may all be concurrently executed, and concurrent execution makes processing times of the related operations become partially or completely overlapped.
