	rfc926 (Site not responding. Last check: 2007-08-11)
		One protocol subset is for use where it is known that the source and destination end-systems are connected by a single subnetwork.
		Protocol Control Information required for delivering the data unit to its destination is determined from current state information and from the parameters provided with the N_UNITDATA Request; e.g., source and destination addresses, QOS, etc. User data passed from the Network Service user in the N_UNITDATA Request forms the Data field of the protocol data unit.
		During the composition of the protocol data unit, a value of the total length of the PDU is determined by the originator and placed in the Segment Length field of the PDU header.

	rfc926 - Protocol for providing the connectionless mode network
		RFC 926 December 1984 During the composition of the PDU, a value of the total length of the PDU is determined by the originator and placed in the Total Length field of the PDU header.
		The address of the originator of the Data Protocol Data Unit is RFC 926 December 1984 conveyed as both the destination address of the Error Report PDU as well as the source address of the original Data PDU; the latter is contained in the Data field of the Error Report PDU.
		In particular, the first inserted octet is interpreted as the network layer protocol identifier, probably eliminating any knowledge that the data unit is related to the RFC 926 December 1984 ISO 8473 Protocol, and thereby eliminating any attempt to perform the checksum calculation or invoking a different form of checksum calculation.

	ISO CLNP: Connectionless Network Protocol (ISO-IP, ISO 8473, RFC 994, X.213, X.233)
		Connectionless Network Protocol (CLNP) is an ISO network layer datagram protocol by the layers defined in the Reference Model for Open Systems Interconnection.
		CLNP (Connectionless Network Protocol) may be used between network-entities in end systems or in Network Layer relay systems (or both).
		CLNP (Connectionless Network Protocol) provides the same maximum datagram size as IP, and for those circumstances where datagrams may need to traverse a network whose maximum packet size is smaller than the size of the datagram, CLNP (Connectionless Network Protocol) provides mechanisms for fragmentation (data unit identification, fragment/total length and offset).

	Communications protocol - Wikipedia, the free encyclopedia
		An example of a simple communications protocol adapted to voice communication is the case of a radio dispatcher talking to mobile stations.
		Protocol layering allows the parts of a protocol to be designed and tested without a combinatorial explosion of cases, keeping each design relatively simple.
		Thus, layering enables a "mix-and-match" of protocols that permit familiar protocols to be adapted to unusual circumstances.

	Connection-Oriented and Connectionless Protocols
		Protocols can be either connection-oriented or connectionless in nature.
		Connectionless protocols differ markedly from connection-oriented protocols in that they do not provide the capability for error, sequence and flow control.
		Connectionless protocols are always in the data transfer phase, with no explicit setup or release phases as in connection-oriented protocols.

	Connectionless protocol - Wikipedia, the free encyclopedia
		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.
		Connectionless protocols are often disfavoured by network administrators because it is much harder to filter malicious packets from a connectionless protocol using a firewall.
		Connectionless protocols are usually described as stateless because the endpoints have no protocol-defined way to remember where they are in a "conversation" of message exchanges.

	IS-IS routing protocol, ISO CLNP and ISO IGRP, Connectionless Network Protocol
		Connectionless Network Protocol (CLNP) is a protocol stack developed originally as a replacement for TCP/IP with the anticipation that this OSI suite would take over being based upon the standard OSI 7-layer model.
		The protocol that allows End Systems to connect to Intermediate Systems is End System to Intermediate System (ES-IS) and this is done by forming adjacencies between the ES and the IS. In the TCP/IP world the equivalent to the job that ES-IS does is carried out by ARP, IRDP or by setting a default gateway.
		ISO IGRP is an alternative routing protocol to IS-IS and allows the use of routing between domains and therefore greater scalability of ISO.

	DCE 1.1: Remote Procedure Call - RPC Protocol Definitions
		The server call protocol machines (CO_SERVER and CL_SERVER) are instantiated at an RPC request for a call in a new session, which is a new association for the connection-oriented protocol or a new activity for the connectionless protocol.
		Similarly, the lifetime of a protocol machine instance is determined by events that cause transition to the terminal state.
		Since the connectionless RPC protocol machines have to take into account the unreliable nature of the underlying datagram transport, the RPC run-time system has to handle fragmentation, the possible delivery of packets out of order, and the reassembly of the entire request or response data.

	[No title]
		The connectionless Internetwork Protocol does not guarantee the delivery of PDUs; hence, it is possible for some segments of a PDU to be lost or delayed such that the entire PDU cannot be assembled in a reasonable length of time.
		This scheme is attractive since the delivery behavior of the ISO 8473 Protocol would be identical for segmented and unsegmented PDUs.
		A.2.3 Method (c) couples the reassembly lifetime directly to the Transport Protocol's retransmission timers, and requires that Transport Layer management make known to Network Layer Management (and hence, the Reassembly Function) the values of its retransmission timers for each source from which it expects to be receiving traffic.

	The TCP/IP Guide - Connection-Oriented and Connectionless Protocols
		Another way in which technologies and protocols are differentiated has to do with whether or not they use connections between devices.
		Protocols are divided into two categories based on their use of connections:
		Key Concept: A connection-oriented protocol is one where a logical connection is first established between devices prior to data being sent.

		It is observed that the connection setup and tear-down protocol exchanges and complex connection-oriented protocol machines become unnecessary overheads for a simple request/response exchange between a client application and a server application, especially in reliable communications environments such as LAN and ISDN.
		The OSI connectionless upper layers are thought to be highly effective and efficient, both in time and space, for the distributed application classes mentioned above.
		By offering an OSI connectionless transport service on top of the Internet, this RFC will allow future applications to use the OSI connectionless upper-layer services, which are required to be conformant to the OSI upper layer Shue, Haggerty & Dobbins [Page 6] RFC 1240 OSI on top of UDP June 1991 architecture.

	Connection-Oriented and Connectionless Services (Linktionary term)
		Connection-oriented methods may be implemented in the data link layers of the protocol stack and/or in the transport layers of the protocol stack, depending on the physical connections in place and the services required by the systems that are communicating.
		TCP (Transmission Control Protocol) is a connection-oriented transport protocol, while UDP (User Datagram Protocol) is a connectionless network protocol.
		The Internet is one big connectionless packet network in which all packet deliveries are handled by IP.

	RFC 926 (rfc926)
		If a third subnetwork had normal delays ranging from.1 to 1 second, but occasionally delivered an NPDU after a delay of 15 seconds, the intermediate system attached to this subnetwork might be required to determine how long it has actually take the PDU to transit the subnetwork.
		In this last example, it is likely to be more useful to have the intermediate systems determine when the delays are extreme ad discard very old NPDUs, as occasional large delays are precisely what causes the Transport Protocol the most trouble.
		In addition to the time delay within each subnetwork, it is important to consider the time delay within intermediate systems.

	CLNP (Connectionless Network Protocol) (Linktionary term) (Site not responding. Last check: 2007-08-11)
		CLNP is the equivalent of the IP (Internet Protocol) for OSI (Open Systems Interconnection) networks, with the primary difference being the size of the address.
		However, the OSI protocols have not gained worldwide acceptance and do not appear to be viable for anything other than a reference model at this writing.
		At one time, it was thought that OSI protocols would replace the Internet protocols on the government-funded Internet.
