Abstract:
1. A packet receiving method for use on a packet-switching network for handling received packet, comprising the steps of: allocating a descriptor and a data buffer, the descriptor for recording a link status between the descriptor and the data buffer and a reception status of a packet, and the data buffer for storing the packet, and a size of the data buffer being fixed; activating an early interrupt mode and setting a logical segmentation size value; dividing the data buffer by the logical segmentation size value into a plurality of segments, and setting an early receiving interrupt signal and a ready interrupt signal according to the logical segmentation size value; in response to the early receiving interrupt signal, reading a part of the packet stored in the data buffer, and not performing a write-back operation after reading the part of the packet stored in the data buffer; and in response to the ready interrupt signal, retrieving and forwarding a remaining part of the packet stored in the data buffer.
