ABSTRACT:
A data transfer system efficiently allocates contiguous address spaces in a destination storage area to packets by maintaining a plurality of lists from which different amounts of contiguous address spaces are allocated. List selection is made based on known or presumed packet characteristics. By arranging different lists to supply contiguous address spaces in different amounts based on packet-specific characteristics, over-allocation of address space may be reduced considerably while contiguous address space is guaranteed on a continuous basis.
