The peer-to-peer topology consists of three different types of nodes: PAN
coordinator, full function node and reduced function nodes. In the peer-topeer
topology, an arbitrary array of connections can be created between full
function devices and the PAN coordinator. Since a network layer is not
defined in the standard, routing is not directly supported (refer to Figure 1 and
Figure 3).
