Applications of UDP:
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-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.
Difference between Connection-oriented and Connection-less Services:
| S.NO | Connection-oriented Service | Connection-less Service |
|---|---|---|
| 1 | Connection-oriented service is related to the telephone system. | Connection-less service is related to the postal system. |
| 2 | Connection-oriented service is preferred by long and steady communication. | Connection-less Service is preferred by bursty communication. |
| 3 | Connection-oriented Service is necessary. | Connection-less Service is not compulsory. |
| 4 | Connection-oriented Service is feasible. | Connection-less Service is not feasible. |
| 5 | In connection-oriented Service, Congestion is not possible. | In connection-less Service, Congestion is possible. |
| 6 | Connection-oriented Service gives the guarantee of reliability. | Connection-less Service does not give a guarantee of reliability./td> |
| 7 | In connection-oriented Service, Packets follow the same route. | In connection-less Service, Packets do not follow the same route. |
| 8 | Connection-oriented services require a bandwidth of a high range. | Connection-less Service requires a bandwidth of low range. |
| 9 | Ex: TCP (Transmission Control Protocol) | Ex: UDP (User Datagram Protocol) |
| 10 | Connection-oriented requires authentication. | Connection-less Service does not require authentication. |
