•
Advertisement Period: This is the frequency that the router broadcasts UPnP
information over the network. A large value will minimize network traffic but
cause delays in identifying new UPnP devices to the network.
•
Advertisement Time to Live: This is expressed in hops for each UPnP packet. This
is the number of steps a packet is allowed to propagate before being discarded.
Small values will limit the UPnP broadcast range. A default of 4 is typical for
networks with few switches.
