Connection-oriented networks

[Filipe Araujo <filipius@titanic.di.fc.ul.pt>]

	Hello,

	I'm a newcomer to ns-2, and I would like to know if it is possibly
and/or easy to simulate a connection-oriented network with ns-2 (I believe
ns-2 is intended primarily to simulate packet-switched networks).
	Thank you in advance.
	Best regards,

	Filipe Machado de Araujo.
