An example of connection-oriented network architecture is the circuit switching network, such as was used in early telephone systems. Circuit switching networks can be used to transmit analogue or digital data. An example of the opposite would be packet switching.

,,,,,,,,,,,please pay attention to word
"opposite"
In the quote above what is meant by : " opposite ." ? ,,,,was it meant to be translated as : " non connection-oriented" ? or it was meant to be translated as: "non circuit-switching " ?
Because if it is meant to be translated as : " non connection-oriented" , then I feel there is contradiction with below :
((Traditionally, three methods of switching have been important: circuit switching, packet switching , and message switching.
Packet switching itself (my concern) uses either virtual circuit approach or the datagram approach
virtual circuit approach can be divided to either permanent virtual circuit (Frame Relay )or switched virtual circuit (X.25) ,,,,both frame Relay and X.25 are connection oriented, hence it contradicts with what wikipedia syas ))
Any insight ?
