IESG received this comment. I guess the answer is: no difference
right?
Thanks,

I have some doubt with the following text about virtual concatenation.
-----------------
The standard definition for virtual concatenation allows each
virtual concatenation components to travel over diverse paths.
Within GMPLS, virtual concatenation components must travel over
the same (component) link if they are part of the same LSP. This
is due to the way that labels are bound to a (component) link.
Note however, that the routing of components on different paths is
indeed equivalent to establishing different LSPs, each one having
its own route. Several LSPs can be initiated and terminated
between the same nodes and their corresponding components can then
be associated together (i.e. virtually concatenated).
---------------
I wonder what's the difference between "virtual concatenation" and "virtually concatenated"?
Thanks!
