LEAP supports self-assembling addressable rings. At initialization time, the ring enumerates each node with a unique identification. This identification is include in subsequent traffic from this node. Nodes may send messages to other nodes by specifying the node ID as part of the message. The addressable ring node will filter messages according to identification. The addressable ring is very helpful in creating scalable services on the FPGA.
