As stated previously, a mesh network is a network of
248 Chapter 9
nodes with all or many nodes in the network having multiple connections to the
other nodes. Consequently, there are multiple paths from each node to any other
node in the network. The denser a mesh network, the more alternate paths there
are in the network. In the event that a failure occurs in a path such that the traffic
cannot be routed through the path, alternate paths may be used to route the traffic.
In general, a mesh network does not have a single point of failure. Therefore, mesh
networks provide a level of redundancy unmatched by most other types of networks.
?– High end-to-end capacity For the same reason that a mesh network provides
ample redundancy, it also provides a higher level of end-to-end capacity than could
normally be realized. In a mesh network, each alternate path not only serves as a
backup path to be used during failure, it also serves as an alternate path to be used to
serve more capacity. For example, in Figure 9.5, traffic from node A to B can be routed
along node C to the extent that the path through node C meets the capacity demand
of the traffic.
