Unified Services Router
•
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.
