networks, subnets and routers. Those concepts should continue to be basic building blocks of software defined networks. The layer 4+ stuff should be added on top with clean interfaces that don’t entangle functionality up and down the stack.<u></u><u></u></span></tt></p>

to deal with are the ones like SIP where clean separation of layers was indiscriminately violated.<u></u><u></u></span></tt></p>
