Abstract
System and method for routing data packets in an Ethernet switch. A preferred embodiment comprises receiving a data frame at a first port, wherein the data frame comprises a header portion and payload portion. The header portion is analyzed to determine a destination port for the data frame. A destination status is added to the header portion to create a modified header portion. The modified header portion is stored in an on-chip memory. The payload portion is stored in an off-chip memory. An on-chip CPU instructs a DMA controller how to route the data frame.
