ABSTRACT:
This invention discloses a dynamic memory allocation method for an Ethernet switching architecture, which can resolve problems with the limitations of transmission bandwidths and transmission port counts in a conventional network packet switching. The method comprises steps of providing a plurality of input ports and output ports, providing a shared memory for storing packet segments of a plurality of packets, providing a first link RAM (Random Access Memory) for controlling a making and reading of a single linked list for the packet segments of each the plurality of packets, and providing a second link RAM serving as a FIFO (first in first out) device for co-managing an obtaining of the link address spaces at the corresponding input ports before the single linked list been made, and a releasing of the link address spaces at the corresponding output ports after the single linked list been read.
