[e2e] What is the meaning of "end-to end"?

[demir]

What is "N"? If it is "the number of ends", I find this
"ambigious" because N can be very large, but the system might do
unicasting. To me, "casting" is "directing". 
N =0, Nocasting
N =1, Unicasting
N>=2, Multicasting
N=Maximal (a special edge-case of Multicasting), where Maximal>=2
If "multi" is not used in "literally", they all can be seen as special
case of multicasting.
