connectionless
Last modified: Friday, June 07, 2002
Refers to network protocols in which a host can send a message without establishing a connection with the recipient. That is, the host simply puts the message onto the network with the destination address and hopes that it arrives. Examples of connectionless protocols include Ethernet, IPX, and UDP.
In contrast, connection-oriented protocols require a channel to be established between the sender and receiver before any messages are transmitted.
