However, if more capacity is needed than what is offered by the path
through C, the path through node D could also be used to meet the higher demand.
?– High network capacity A mesh network allows for more efficient use of available
network resources thereby maximizing network capacity. High end-to-end
capacity, as discussed above, is one example of an efficient use of network resources.
In a similar fashion, traffic between one set of nodes can be routed without

compromising the capacity available to route traffic between another set of nodes.
For example, as illustrated in Figure 9.5, data traffic between node A and node B
can be routed (along the dotted line connecting the two nodes) without affecting the
data traffic between node E and F (which is routed along the dotted line connecting
the two nodes). In the similar fashion, mesh networks can confine regional traffic
to the region without compromising capacity throughout the rest of the network.
For example, traffic between node G and H can be confined to the links shown by
the dotted lines without affecting the traffic in other parts of the network.
