:as above, will appreciate if there is a diagram to show me.

"Hub and spoke" refers to a configuration in which you have several
remote sites (the "spokes") that never connect directly to each other:
instead, when they want to communicate, they send all the traffic through a
single central site (the "hub").

The terms are by analogy to wagon wheels (or bicycle wheels.)


A B
\ /
\ /
C---- HUB -----D
/ | \
/ | \
E F G


In order for A to communicate with F, A has to talk to the hub, and the
hub passes the messages on to F.

The opposite of "hub and spoke" is "fully meshed" or at least "partly meshed".
Imagine drawing an additional line in the diagram, directly connecting
D and G, so that when D and G wanted to talk, they talked directly instead
of going through the hub. For example, D and G might be the Auditing
and Payroll departments, and might happen to be in buildings across the
road from each other. It might make sense to put in a direct link
between them as well as the links back to corporate headquarters in
a different city. But it might not make sense to put in a direct link
between the Advertising department in Alabama and the shipping
department in Winnipeg.
