Hi all,

 The Maximum Transmission Unit (MTU) is a parameter that determines
the largest datagram than can be transmitted by an IP interface
(without it needing to be broken down into smaller units). The MTU
should be larger than the largest datagram you wish to transmit
unfragmented. Note: this only prevents fragmentation locally. Some
other link in the path may have a smaller MTU: the datagram will be
fragmented at that point. Typical values are 1500 bytes for an
ethernet interface, or 576 bytes for a SLIP interface.

this is the correct definition of MTU isn't it ....?????

"larger than the largest datagram you wish to transmit" kind of implies
that you have some choice in the matter.  I'd just edit your first sentence:

The Maximum Transmission Unit (MTU) is the largest packet than can be
transmitted by an interface without it needing to be broken into smaller
units.
