Question

TCP can be implemented in virtual circuits. (TRUE /FALSE )
Explain.

Comments

i was thinking something else and answered something else, now see again my comment.

TCP uses pseudo virtual circuit switching, how can TCP use virtual circuiting, when it use IP at N/W layer(which uses datagram switching), but atleast it keep reserve resources at end points, so it is somewhere b/w datagram and virtual circuting.

Yeah I agree with it, i.e.  what TCP is Currently (its used in datagram)
But Coming to the statement can it be used in Virtual circuits ?
then  why not? TCP has also a reliable mechanism.

see this https://en.wikipedia.org/wiki/Virtual_circuit#Layer_4_virtual_circuits
layer 4 virtual circuits

Also How can we do it in IPv6 ?
