You don't need a connection oriented protocol per se, but you do need
*some* notion of connection *somewhere*. In some such protocols you merely
agree with the network that all packets marked with a certain flag between
you and a specified remote host will have certain guarantees of delivery
within a certain timeframe as long as the bandwidth they attempt to use
doesn't go above the agreed limit.
This 'flow', as it is called, can then be used for any packets you want -
TCP, UDP, etc...
