Hello Friends, In this blog post I am going to let you know about the UDP(User Datagram Protocol).
Inside this blog post, we are going to let you know about What is User Datagram Protocol in networking? What is an example of UDP? What is the main difference between TCP and UDP? Where is the UDP protocol used?
What is the User Datagram Protocol in networking?
UDP stands for user datagram protocol, this is a communication protocol like TCP/IP and is used to exchange the message between two computing devices. It is referred sometimes as UDP/IP when it is used in the network.
What is an example of UDP?
There are various examples of UDP in the network like Domain name system, where one single request is sent and one data packet is sent back to the request as UDP must be fast and having a single request at a time. It is also used in SNMP(Simple network management protocol), RIP(routing information protocol), and DHCP(dynamic host control protocol).
What is the main difference between TCP and UDP?
TCP is known as a connection-oriented protocol whereas UDP is a connectionless protocol. In the TCP protocol, the first connection is established between the sender and receiver. But UDP does not make any connection before sending the data packet. UDP is faster as compared to TCP.
Where is the UDP protocol used?
UDP is used in routing update protocol like RIP. This protocol is generally used in real-time events or functions where the time delay can not be tolerated for sure.
UDP is another transport layer protocol that is part of the TCP/IP suite. It is an unreliable, connectionless protocol that does not guarantee delivery and duplicate protection.
UDP is basically just IP with a short header added. It provides non-sequential transport functionality when reliability and security are less important than size and speed.
UPD provides a way for applications to send encapsulated raw IP datagrams without establishing any connection. UDP is more appropriate than TCP in some context; like it is more robust at lower layers.
UDP has very little to do. Mainly, it adds a port addressing capability to IP. Since its header it shorter, it involves fewer overheads. UDP is used by applications that do not want TCP’s sequencing and flow control and wish to provide their own.
UDP is widely used for one-shot, client-server type request-reply queries and applications in which prompt delivery is more important than accurate delivery, such as transmitting speech or video.
Thus, there is a place at the transport layer for both connection-oriented and connectionless type of service. UDP is described in RFC 768. UDP provides a connectionless service for application-level procedures.
Therefore, UDP is an unreliable service. However, the overhead of the protocol is low, which may be enough in several cases. An example of the use of UDP is in the context of network management. The relation of IP, TCP and UDP are shown in the below-given fig.
