ROUTING METHOD AND SYSTEM FOR DATA BASED ON NETWORK USING FRAME ADDRESS NOTIFICATION

摘要

PROBLEM TO BE SOLVED: To provide an improved method and a system which perform routing of data adjusted to a frame based on a network. SOLUTION: A host processor 44 starts an address lookup algorithm for analyzing burst of transferred data and feeding a frame to a desired destination. A common system memory 46 receives data including an address field selected in advance. A network device has plural ports and each port has a FIFO reception memory for receiving at least a first part of the frame. This first part has data equipped with the address field selected beforehand. A DMA unit transfers burst of the data from the FIFO reception memory to the common system memory 46. A communication processor selects an amount of data to be transferred from the FIFO reception memory on the basis of the desired address field to be analyzed by the host processor.
