Abstract
A network buffer memory is divided into pools of locations including a plurality of tinygram contiguous sections and a plurality of jumbogram contiguous sections. The tinygram contiguous sections available for storage of packets are listed in a list of tinygram pointers. The jumbogram contiguous sections available for storage of packets are also listed in a list of jumbogram pointers. A threshold for distinguishing the packets as tinygrams and jumbograms is programmed. As packets are received, they are measured against the threshold. Responsive to detection of an end of packet condition prior to reaching the threshold, storing the packet in a tinygram contiguous section. Otherwise, the packet is stored in a jumbogram contiguous section. Availability of sections is determined by query to the FIFO lists of pointers.
