connectionless protocol

The data communication method in which communication occurs between hosts with no previous setup. Packets sent between two hosts may take different routes. UDP is a connectionless protocol. Also called packet switching. Contrast circuit switching, connection-oriented.

connectionless

A communications architecture that does not require the establishment of a session between two nodes before transmission can begin. For example, the transmission of frames within a local area network (LAN), such as Ethernet, Token Ring and FDDI, is connectionless. As soon as a frame has been constructed, it is inserted into the network (put on the wire).

In an IP network, the UDP transport protocol, which is used for voice over IP (VoIP) and video calling, is connectionless. Contrast with connection oriented. See UDP.

The connectionless protocol helps launch mass-generated botnets, which also saps host resources and can ultimately make them inaccessible.
UDP is an unreliable and connectionless protocol for medical applications that transmits interactive and real-time data but it is considered to be a good candidate protocol for multimedia streaming and voice transmission over the internet protocol (VoIP).
This type of routing protocol is table driven and similar to the connectionless protocol of conventional TCP/IP networks.
Since BACNET (Building Automation Control Network) is a connectionless protocol, the need for message segmentation and end-to-end error checking is much less than in a connection-based protocol.
For a connectionless protocol, the only way to make performance measurements associated with a specific packet's route is through the packet header.
It is a connectionless protocol which adds a level of reliability and multiplexing to IP.
UDP is a connectionless protocol which, like TCP, is layered on top of IP.
Anycast is best suited to connectionless protocols like UDP, rather than connection-oriented protocols such as TCP, since the receiver selected for any given source may change from time to time as optimal routes change.
