Figure 4-8. Node Joins Network Via Rejoin Procedure with PDS Used in Application.
The silent rejoin is very useful when nodes are reset after a battery change, or after a mains-powered network has reset
after a power outage. The nodes come back into the network seamlessly and can route packets, with their networking
tables restored from Persistent memory to RAM.
Packet #9 shows a device announcement frame. This broadcast frame is sent by a device after it has properly
authenticated into the network.
Devices that receive this frame update their network address map tables with the device information obtained in the
device annce frame.

Self-Leave and Parent-Induced Leave
ZDP Requests are managed by the ZDO layer and can be used for various network control scenarios as detailed in [1].
Network leave can be processed using ZDP requests when a device needs to leave the network on certain events.
Network leave can be self-induced on a node or a node can order another remote node to leave the network.
