ABSTRACT:
A network device includes an alignment module to align payloads of received frames on memory boundaries in a buffer memory. The frames may be Ethernet frames which encapsulate IP (Inernet Protocol) packets as payloads. The alignment module prefixes dummy bytes to the frame header to shift the IP payload into an aligned position in the memory regions of the memory.
