A number of characteristics can be used to describe communications protocols. TCP is an example of a connection-oriented protocol.

Communication can be established in two ways between two or more devices that are connection-oriented and connection-less. Network layers can offer these two different types of services to its predecessor layer for transferring data. Another difference between connection-oriented and connection-less services is connection-oriented communication uses a stream of data and is vulnerable to router failure while connection-less communication uses messages and is robust to router failure.

9 Difference between Connection-Oriented and Connectionless Services Protocol
Connection-oriented communication is a network communication mode in telecommunications and computer networking, where a communication session or a semi-permanent connection is established before any useful data can be transferred, enabling the ability to ensure that data is delivered in the correct order to the upper communication layer. The alternative to connection-oriented transmission is connectionless communication , for example the datagram mode communication used by the IP and UDP protocols, where data may be delivered out of order, since different network packets are routed independently, and may be delivered over different paths. Connection-oriented communication may be a circuit switched connection, or a packet-mode virtual circuit connection. In the latter case, it may use either a transport layer virtual circuit protocol such as the TCP protocol, allowing data to be delivered in order although the lower-layer switching is connectionless, or it may be a data link layer or network layer switching mode, where all data packets belonging to the same traffic stream are delivered over the same path, and traffic flows are identified by some connection identifier rather than by complete routing information, allowing fast hardware based switching [ clarification needed ]. Connection-oriented protocol services are often, but not always, reliable network services, that provide acknowledgment after successful delivery, and automatic repeat request functions in case of missing data or detected bit-errors. Circuit mode communication provides guarantees that data will arrive with constant bandwidth and at constant delay and in-order delivery of a bit stream or byte stream is provided. The switches are reconfigured during a circuit establishment phase.
Connection-oriented service works more like a telephone system in where we pick up the phone, make a call, talk, and then hang up the phone. Similarly, there is a dedicated line between the sender and the receiver on a network when it comes to connection-oriented service. Connection-oriented service works more like a virtual tube in which the sender sends the data and they arrive in the order they were pushed by the sender to the receiver. We have already seen that how much QoS is important in the computer networks. During connection-oriented setup, for QoS purpose, a lot of negotiations can also happen at the beginning such as data delivery rate as we have already in the ATM networks , message size, etc.

Difference Between Connection-oriented and Connection-less Services
When one computer wants to send a packet to another computer connected to the internet, cumbersome operations are executed including establishing the connection between sender and receiver. The services provided by these protocols are of two types- Connection-oriented and connectionless services. The computer sending data is called as a sender and the computer receiving data is called as a receiver. The data message is also referred as a packet. In between sending a packet from the sender to receiver, there are cumbersome operations involved. Is destination agree with the accepting the packet? Getting the answer to all the questions is the first priority before sending the packet over the network.

Not guaranteed. Congestion Unlikely Occur likely. Transferring mode It can be implemented using circuit switching and virtual circuit. It is implemented using packet switching.
Messung, Modellierung und Bewertung von Rechensystemen pp Cite as. Communication architectures with a multi-layer protocol structure are extremely difficult to evaluate due to the model complexity. In this paper, a hierarchical decomposition and aggregation technique is described which is oriented at the ISO Basic Reference Model. In particular, connection-oriented and connectionless data transmission are compared to each other quantitatively. The modelling and performance evaluation technique is exemplified for the example of a Local Area Network.
Connection-Oriented Vs Connection-Less Service: Differences And Working Functionalities
There is a sequence of operation to be followed by the users of connection oriented service. These are:. In connection oriented service we have to establish a connection before starting the communication. When connection is established, we send the message or the information and then we release the connection. Connection oriented service is more reliable than connectionless service.
Both Connection-oriented service and Connection-less service are used for the connection establishment between two or more than two devices. These type of services are offered by network layer. Connection-oriented service is related to the telephone system. It includes the connection establishment and connection termination. In connection-oriented service, Handshake method is used to establish the connection between sender and receiver.
Проваливал бы ты отсюда. - Я ищу одного человека. - Знать ничего не знаю. - Не знаю, о ком вы говорите, - поправил его Беккер, подзывая проходившую мимо официантку. Он купил две бутылки пива и протянул одну Двухцветному.
