IP Statistics: Field Definitions

Field

Name

Values Description

UDP versus TCP (continued).

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).
