Bridging the Link and 10BaseT Networks
Because the CPU is a bridging device that connects a
10BaseT Network to a wireless link, the CPU must learn
about the network. The CPU dynamically learns MAC
Addresses as distant network nodes.
The CPU passes data packets that are addressed to far-end
network users found in its current service table. If a data
packet is addressed to a distant network node that is in the
current service table, the CPU accepts the data packet, then
forwards that packet to the distant CPU. When a distant node
is not in the current service table, the CPU does not pass
data packets for that node through to the wireless link.
This method of filtering keeps the wireless link free from
unnecessary messages, so that the wireless link provides the
maximum performance and speed possible.
