Advantages with this over connectionless packet switching are: * Bandwidth reservation during the connection establishment phase is supported, making guaranteed Quality of Service (QoS) possible.
Connectionless and connection-oriented modes Packet switching may be classified into connectionless packet switching, also known as datagram switching, and connection-oriented packet switching, also known as virtual circuit switching.
For a brief period, the specification also included a connectionless datagram service, but this was dropped in the next revision.
Historically, IP was the connectionless datagram service in the original Transmission Control Program introduced by Vint Cerf and Bob Kahn in 1974; the other being the connection-oriented Transmission Control Protocol (TCP).
In connectionless mode no optimizations are possible when sending several data units between the same two peers.
In connectionless transmissions the service provider usually cannot guarantee that there will be no loss, error insertion, misdelivery, duplication, or out-of- sequence delivery of the packet.
