In a packet-switched network, connectionless mode transmission is a transmission in which each packet is prepended with a header containing a destination address sufficient to permit the independent delivery of the packet without the aid of additional instructions. Wikipedia does not have an article with this exact name. ...
In telecommunications, connectionless describes communication between two network end points in which a message can be sent from one end point to another without prior arrangement. ...
In computer networking and telecommunications, packet switching is a communications paradigm in which packets (messages or fragments of messages) are individually routed between nodes, with no previously established communication path. ...
In telecommunications, transmission is the act of transmitting electrical messages (and the associated phenomena of radiant energy that passes through media). ...
In information technology, Header refers to supplemental data placed at the beginning of a block of data being stored or transmitted, which contain information for the handling of the data block. ...

A packet transmitted in a connectionless mode is frequently called a datagram. A packet is the fundamental unit of information carriage in all modern computer networks. ...
In connection-oriented communication the stations about to exchange data first need to declare towards each other that they want to do so. This is called "establishing a connection". A connection is sometimes defined as a logical relationship between the peers exchanging data. A connection-oriented networking protocol is one which identifies traffic flows by some connection identifier rather than by explicitly listing source and destination addresses. ...
An advantage of connectionless mode over connection-oriented mode is that it allows for multicast and broadcast operations, which may save network resources when the same data needs to be transmitted to several recipients. In contrast, a connection is always unicast (point-to-point). Routing Schemes anycast broadcast multicast unicast Multicast is sometimes also used to refer to a multiplexed broadcast, although that is a very different thing and should not be confused. ...
Broadcasting is the distribution of audio and/or video signals which transmit programs to an audience. ...
In computer networks, unicast is the sending of information packets to a single destination. ...
Unfortunately, in connectionless mode transmission of a packet, the service provider usually cannot guarantee that there will be no loss, error insertion, misdelivery, duplication, or out-of-sequence delivery of the packet. (However, the risk of these hazards may be reduced by providing a reliable transmission service at a higher protocol layer of the OSI Reference Model.) The word error has different meanings in different domains. ...
In mathematics, a sequence is a list of objects (or events) arranged in a linear fashion, such that the order of the members is well defined and significant. ...
For other senses of this word, see protocol. ...
Layer may refer to: Look up Layer in Wiktionary, the free dictionary. ...
The Open Systems Interconnection Reference Model (OSI Model or OSI Reference Model for short) is a layered abstract description for communications and computer network protocol design, developed as part of the Open Systems Interconnect initiative. ...
Another drawback of the connectionless mode is that no optimisations are possible when sending several frames between the same two peers. By establishing a connection at the beginning of such a data exchange the components (routers, bridges) along the network path would be able to pre-compute (and hence cache) routing-related information, avoiding re-computation for every packet. Network components could also reserve capacity for the transfer of the subsequent frames of e.g. a video download. This article is about a computer networking device. ...

The distinction between connectionless and connection-oriented transmission may take place at several layers of the OSI Reference Model: The Open Systems Interconnection Reference Model (OSI Model or OSI Reference Model for short) is a layered abstract description for communications and computer network protocol design, developed as part of the Open Systems Interconnect initiative. ...
In computing and telecommunications, the transport layer is the second highest layer in the four and five layer TCP/IP reference models, where it responds to service requests from the application layer and issues service requests to the Internet layer. ...
The Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol suite, often simply referred to as TCP/IP. Using TCP, applications on networked hosts can create connections to one another, over which they can exchange streams of data using Stream Sockets. ...
The Transport protocol is a protocol on the transport layer of the OSI model. ...
User Datagram Protocol (UDP) is one of the core protocols of the Internet protocol suite. ...
The network layer is third layer out of seven in OSI model and it is the third layer out of five in TCP/IP model. ...
