A technique is described to improve memory management local network architecture by utilizing dual FIFO (first-in first-out) buffers. Memory management, when used in a high-speed communications network switching architecture, such as a buffer-insertion ring-type architecture, must provide the following conditions: 1. Variable message length for received messages; 2. Track the beginning and ending addresses of variable message lengths to determine byte count; 3. Dynamically assign RAM (Random Access Memory) allocation for efficient utilization of microprocessors and I/O (Input/Output) devices; and 4. Dynamically allocate RAM segments for transmission of messages.
