Network Node Dimensioning

In order to determine the number of nodes of each type in the network, we
must first understand the dimensioning rules associated with each type of
node. If we understand the capacity limits of a given node type, then we can
determine the minimum required number of nodes of that type. For a number
of reasons, it is likely that we will deploy greater than the minimum
number, but we must at least know the starting point.
Of course, for a given node type, the dimensioning rules and capacity limits
will vary from vendor to vendor. Any examples provided in the following
sections should be considered examples only and do not necessarily reflect
the characteristics of any given vendor’s implementation.
