tcp ip - If IP is connectionless protocol then why does virtual packet switching is connection oriented? -

-

we ip connection less protocol network layer provides switching facility wherein have packet switching under which, have virtual packet switching connection oriented i.e resources reserved on way. why ip connection less every packet travels in ip datagram?

well think network layer has many other protocols might use virtual ckt concept. ip uses datagram service, connectionless. because in datagram service packets go independently without reservation of resources.
