Abstract

The invention provides a network packet receiving management method and a network control circuit with a network packet receiving management function. The method comprises the following steps: providing a buffer unit comprising a plurality of data blocks with the number of the first packets and a plurality of data blocks of the number of the second packets, wherein a plurality of data blocks with the number of the first packets are used for respectively storing a plurality of first network packets according to a first array data structure which contains a plurality of first packet description descriptors corresponding to the number of the first packet, and a plurality of data blocks with the number of the second packet do not correspond to any packet descriptor; and modifying the first packet descriptors corresponding to the first data blocks into a designated second data blocks not corresponding to any packet descriptor.

Description

technical field [0001] The present invention relates to a method for receiving and managing network packets and its related devices, in particular to a method for receiving and managing network packets based on a data array structure and its related devices. Background technique [0002] Network Interface Controller (NIC) is used to provide an identifiable address when an electronic device is connected to a network and serve as a communication interface between the two. After the electronic device successfully receives a network from the network After grouping, the network control chip uploads the network packet to a processing unit of the electronic device and receives a network packet returned by the processing unit. The data structures used by network control chips today are generally linked-list data structures or array data structures. The serial data structure indicates the network information on a received network packet. The address of the previous, next, or next ne...
