UDP- DATAGRAM TRANSPORT SERVICE

INTRODUCTION:

 UDP is the one of the transport protocols in TCP/IP protocol suite. UDP protocol accepts applications on the computers to transmit and receive datagram packet. UDP has a packet format. It uses best-effort delivery function.

 

THE NEED FOR TRANSPORT PROTOCOLS:

 Internet protocol can not differentiate between application programs running on the similar computer. Fields in the IP datagram header denote to computers, not applications. A protocol that gives an application program to operate as the end point of communication is called as a transport protocol or an end-to-end protocol.

 

THE USER DATAGRAM PROTOCOL (UDP):

 TCP/IP has two transport protocols:

  • UDP
  • TCP

 

UDP:

 UDP is less complex and simpler to understand. It does not give the type of service a typical application expects.

 

CHARACTERISTICS OF UDP:

UDP has the following functionalities.

  • It is an end-to-end protocol. It gives application-to-application communication.
  • It gives connectionless service.
  • It is a Message-Oriented architecture.
  • It uses best-effort delivery function.
  • It follows arbitrary interaction.
  • It is platform independent.


THE CONNECTIONLESS PARADIGM:

 

 UDP does not require to pre-establish communication and also there is no requirement to terminate communication. UDP allows an application to time delay long intervals between two messages. There are no Control Messages; only Data Messages. So it has very low load.

 

MESSAGE-ORIENTED INTERFACE:

 

 UDP gives application programs a Message-Oriented Interface. It does not split messages into packets for transmission and does not include messages for delivery.

 

ADVANTAGES:

 

  • Applications can relay on protocol to preserve data boundaries.


DISADVANTAGES:

 

  • Each UDP message have to fit into a single IP datagram.
  • It can result to an inefficient need of the underlying network.
