Term Definition
beacon interval The time interval at which beacon frames are
transmitted. Beacon frames announce the
existence of the wireless network.
DTIM (Delivery Traffic
Indication Message)
A DTIM field is a countdown field informing
clients of the next window for listening to
broadcast and multicast messages. When the
Cisco RV220W has buffered broadcast or
multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value.
Its clients hear the beacons and awaken to
receive the broadcast and multicast messages.
dynamic routing Dynamic routing enables the router to adjust
automatically to physical changes in the
network’s layout. Using the dynamic RIP
protocol, the router calculates the most efficient
route for the network’s data packets to travel
between the source and the destination. The
RIP protocol regularly broadcasts routing
information to other routers on the network. It
determines the best route based on the fewest
number of hops between the source and the
destination.
