Values Description
UDP versus TCP
Protocol versus Transmission Control
Protocol). UDP provides
unguaranteed, connectionless
transmission of data across an IP
network. By contrast, TCP provides
reliable, connection-oriented
transmission of data.
Both TCP and UDP split data into
packets called "datagrams." However,
TCP includes extra headers in the
datagram to enable retransmission of
lost packets and reassembly of packets
into their correct order if they arrive out
of order. UDP does not provide this.
Lost UDP packets are unretrievable;
that is, out-of-order UDP packets
cannot be reconstituted in their proper
order..
Despite these obvious disadvantages,
UDP packets can be transmitted much
faster than TCP packets -- as much as
three times faster. In certain
applications, like audio and video data
transmission, the need for high speed
outweighs the need for verified data
integrity. Sound or pictures often
remain intelligible despite a certain
amount of lost or disordered data
packets (which appear as static).
