Hi,

I think this document should explicitly explains that quantum networks may
and may not execute forwarding (data) in Subsec. 5.1.
Routing and forwarding are different functionalities. Routing decides which
way to go, forwarding executes the transfer obeying the decision.
The 1st and the 2nd generation (Muralidharan's definition) quantum networks
execute routing and swapping, instead of forwarding.
The 3rd generation does routing and forwarding.

"Routing and swapping" might have to be "routing and measuring". "Routing
and measuring" can intuitively cover broader ideas, such as graph
state-based routing and surface code quantum communication, that don't
execute forwarding and don't execute even entanglement swapping, but
execute measurements. (Of course, entanglement swapping has measurements)

Muralidharan's three generations should not be explicitly mentioned in the
document since more types (generations) of quantum networks would appear in
the future.
However, I would believe that any types of quantum networking belong to the
roughly divided two types of quantum networks, "routing and measuring" and
"routing and forwarding". Hence those two types would be worth writing. At
least, it is worth writing that forwarding may not exist, as the unique
distinction of quantum networking.

Such a new section will help network-backgrounded people who may
unconsciously suppose store and forward system.

The current document implies that there are generations of quantum networks
(Subsec. 4.2 Direct transmission mentions "generation"), but no section
summarizes generations. The new explanation would solve the wonder of
readers raised by the implication.

How do you think?

I'm going to make a pull request. Please see that.
