Figure 1. Point-to-point network architecture
All network activity that takes place on wireless bridges is 'transparent' to
the network hosts. In other words, a wireless bridge forwards packets
from one network segment to another according to a 'Forwarding table'.
The forwarding table is built by learning the network topology from
analysis of incoming traffic.
In this configuration, no explicit interaction takes place between the
wireless bridge and the network hosts. The network segments on either
side of the wireless bridge share the same IP subnet. Therefore, each
network host must use a unique IP address within the subnet.
3.2.4. Mesh network architecture
Fluidmesh Networks offers wireless networking solutions that are based
on the mesh networking architecture, but can also fill more traditional
networking roles if needed. This allows substantial reliability and flexibility
advantages when compared to traditional wireless solutions.
A simplified example of a wireless mesh network is shown in
(page
19). In such a network, every Fluidmesh hardware component
transmits the data packets that come from the components directly linked
to it.
In a reliable mesh network with an acceptable amount of redundancy,
every stream of data packets may reach the base station through any of a
variety of paths. The Cisco FM4200 Mobi is designed to act as an
'intelligent router' that is able to forward packets coming from other
Fluidmesh components in real time, based on an optimal, software-
determined path. In addition, the absence of any single point of failure
