Adjective
connectionless (not comparable)
(networking) Without the use of a constant connection; sending and receiving data arbitrarily as needed, usually with less reliability than if a connection were held open.
Advantages with this over connectionless packet switching are: * Bandwidth reservation during the connection establishment phase is supported, making guaranteed Quality of Service (QoS) possible. Source: Internet
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. Source: Internet
For a brief period, the specification also included a connectionless datagram service, but this was dropped in the next revision. Source: Internet
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). Source: Internet
In connectionless mode no optimizations are possible when sending several data units between the same two peers. Source: Internet
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. Source: Internet
