xvi Aironet 340 Series Bridge
Parent/Child Node – Refers to the relationships between nodes in the
wireless infrastructure. The complete set of relationships is sometimes
described as a network tree. For example, the Aironet bridge (at the top
of the tree) would be the parent of the end nodes. Conversely, the end
nodes would be the children of the Aironet bridge.
Association – Each root unit or repeater in the infrastructure contains an
association table that controls the routing of packets between the bridge
and the wireless infrastructure. The association table maintains entries
for all the nodes situated below the Aironet bridge on the infrastructure
including repeaters and radio nodes.
Power Saving Protocol (PSP) and Non-Power Saving Protocol –
The Power Saving Protocol allows computers (usually portable computers)
to power up only part of the time to conserve energy. If a radio node
is using the Power Saving Protocol to communicate with the infrastructure,
the Aironet bridge must be aware of this mode and implement additional
features such as message store and forward.
Bridge System Configurations
The Aironet 340 Series Bridge can be used in a variety of infrastructure
configurations. How you configure your infrastructure will determine
the size of the microcell, which is the area a single bridge will provide
with RF coverage. You can extend the RF coverage area by creating multiple
microcells on a LAN.
Examples of some common system configurations are shown on the
pages that follow, along with a brief description of each.
Point-to-Point Wireless Bridge
The Point-to-Point Wireless Bridge Configuration uses two units to
bridge two individual LANs. Packets are sent between the file server and
Workstation B through the wireless bridge units (root unit and remote
node) over the radio link. Data packets sent from the file server to Workstation
A go through the wired LAN segment and do not go across the
wireless radio link.
