Ultra Low Latency Network Buffer Storage

摘要

Buffer designs and write/read configurations for a buffer in a network device are provided. According to one aspect, a first portion of the packet is written into a first cell of a plurality of cells of a buffer in the network device. Each of the cells has a size that is less than a minimum size of packets received by the network device. The first portion of the packet can be read from the first cell while concurrently writing a second portion of the packet to a second cell.
