4.2 UDP (2/3)
nProvides
connectionless service - no sequencing, no end to end error control (only error detection, includes data), no flow control.
nNFS,
some routing protocols (e.g., RIP), RTP (Real-Time Protocol), TFTP, etc., use UDP as it is simple and fast if reliability is not
an issue.
nIP
will do fragmentation if the UDP packet is too large for the path (i.e., > path
MTU).
