2 Packet switching - Connectionless and connection-oriented packet switching 1 Some connectionless protocols are Ethernet, IP, and UDP; connection oriented packet-switching protocols include X.25, Frame relay, Multiprotocol Label Switching (MPLS), and TCP. https://store.theartofservice.com/the-connectionless-toolkit.html

3 Packet switching - Connectionless and connection-oriented packet switching 1 Thus a virtual connection, also known as a virtual circuit or byte stream is provided to the end-user by a transport layer protocol, although intermediate network nodes only provides a connectionless network layer service. https://store.theartofservice.com/the-connectionless-toolkit.html

4 Packet-switched - Connectionless and connection-oriented packet switching 1 # Connectionless communication|connectionless packet switching, also known as datagram switching; and https://store.theartofservice.com/the-connectionless-toolkit.html

5 Connectionless 1 'Connectionless communication' is a data transmission (telecommunications)|transmission method used in packet switching networks by which each data unit is individually addressed and routed based on information carried in each unit, rather than in the setup information of a prearranged, fixed data channel as in connection-oriented communication. https://store.theartofservice.com/the-connectionless-toolkit.html

6 Connectionless 1 Connectionless communication is often referred to as 'CL-mode' communication.Information Processing Systems - Open Systems Interconnection, Transport Service Definition - Addendum 1: Connectionless-mode Transmission, International Organization for Standardization, International Standard 8072/AD 1, December 1986. https://store.theartofservice.com/the-connectionless-toolkit.html

7 Connectionless 1 Under connectionless communication between two network end points, a message can be sent from one end point to another without prior arrangement. The device at one end of the communication transmits data addressed to the other, without first ensuring that the recipient is available and ready to receive the data. Some protocols allow for error correction by requested retransmission. Internet Protocol (IP) and User Datagram Protocol (UDP) are connectionless protocols. https://store.theartofservice.com/the-connectionless-toolkit.html

8 Connectionless 1 A packet transmitted in a connectionless mode is frequently called a datagram. https://store.theartofservice.com/the-connectionless-toolkit.html

9 Connectionless 1 Connectionless protocols are usually described as stateless protocols because the end points have no protocol-defined way to remember where they are in a conversation of message exchanges. https://store.theartofservice.com/the-connectionless-toolkit.html

10 Connectionless 1 The connectionless communications has the advantage over connection-oriented communications in that it has low overhead. It also allows for multicast and Broadcasting (computing)|broadcast operations in which the same data is transmitted to several recipients in a single transmission. In contrast, a connection is always a unicast (point-to-point) operation. https://store.theartofservice.com/the-connectionless-toolkit.html

11 Connectionless 1 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. However, the effect of errors may be reduced by implementing error correction within an application protocol. https://store.theartofservice.com/the-connectionless-toolkit.html

12 Connectionless 1 In connectionless mode no optimizations are possible when sending several data units between the same two peers https://store.theartofservice.com/the-connectionless-toolkit.html

13 Connectionless 1 * Transport Layer: Transmission Control Protocol|TCP is a connection-oriented transport protocol. User Datagram Protocol|UDP is connectionless. https://store.theartofservice.com/the-connectionless-toolkit.html

14 Connectionless 1 (After the appearance of IBM Advanced Peer-to-Peer Networking|APPN, SNA could operate on a connectionless data link service as well.) https://store.theartofservice.com/the-connectionless-toolkit.html

15 Packet switched network - Connectionless and connection-oriented packet switching 1 Some connectionless protocols are Ethernet, Internet Protocol|IP, and User Datagram Protocol|UDP; connection oriented packet-switching protocols include X.25, Frame relay, Multiprotocol Label Switching (MPLS), and Transmission Control Protocol|TCP. https://store.theartofservice.com/the-connectionless-toolkit.html

16 CLNS - Connectionless-mode Network Protocol (CLNP) 1 In an OSI protocol deployment, CLNS is the service provided by the Connectionless-mode Network Protocol (CLNP) https://store.theartofservice.com/the-connectionless-toolkit.html

17 Service Loading - Connectionless Push 1 In Connectionless Push, an Short Message Service Center|SMSC BIND is required for the PPG to deliver its push message to the mobile station. Typically, a PPG will have a local SMS queuing mechanism running locally that it BINDs to, and which in turn BINDs to the carrier's SMSC. This mechanism should allow for queuing in the event of an SMS infrastructure outage, and also provide for message throttling. https://store.theartofservice.com/the-connectionless-toolkit.html
