Abstract
A distributed router composed of individual units connected by links in a routing fabric which appears to be a single network entity routes multicast packets by bridging to the final unit in the fabric. At the final unit the packet is replicated as necessary and routed. The scheme avoids multiple transmission of the same packet across the fabric.
