Difference between Connection-oriented and Connection-less Services
Both Connection-oriented service and Connection-less service are used for the connection establishment between two or more two devices. These types of services are offered by the network layer.
Connection-oriented service is related to the telephone system. It includes connection establishment and connection termination. In a connection-oriented service, the Handshake method is used to establish the connection between sender and receiver.
Connection-less service is related to the postal system. It does not include any connection establishment and connection termination. Connection-less Service does not give a guarantee of reliability. In this, Packets do not follow the same path to reach their destination.
