that connect network chains together in star configura
tions.
A hop is the transition from one module to another (this
means n-1 hops for n QuantumX modules in a chain).
Depending on the connection situation, 1 to 2 hops are
counted in one hub (see Fig. 7.14).
To count the total number of hops, the longest chain to
the data sink must be counted (worst case).
