UDP : User Datagram Protocol

The User Datagram Protocol (UDP) is a lightweight communication protocol

Differs from TCP in three respects:

• connection-less transmission

• The sender and recipient of UDP data do not keep any information about the state of the communication session between the two hosts.

• best-efforts delivery

• no attempt is made to guaranty that the data is delivered reliably and in order

• packet-based data semantics

Does not establish peer-to-peer connections
