This paper describes several improvements to Lee's multicast switch architecture. Our improvements make Lee's architecture practical, allowing it to achieve maximum network throughput under worst-case conditions and drastically reducing the amount of memory required for addressing of multicast cells. These improvements allow multicast to be added to a 256 port switch with 150 Mb/s links at a cost of about two additional chips per port.
