Excuse me. I meant to ask if a UDP Packet can be fragmented and what happens
to the UDP Header if it can be fragmented?
Thanks.

First, the PDU for UDP is segment, not packet. Correct?

Only the first fragment has the UDP header in it. After that it's just an
IP header and data. Every IP fragment has the same identification number in
the IP header. An offset field in the IP header says where in the
datastream each fragment fits.
So to help you understand this, study t
Ms. Oppenheimer and everyone,
Thank you for your help, it is much appreciated.

Yes. The UDP Header/Data can be fragmented. Part of the Idea behind the OSI
model of Netwrking is that Layer 4 traffic doesn't care what the lower layer
portocols do to the Data/segments/packets/frames/bits, as long as when it
reaches Layer 4 on the destination host it looks The same as
Hi Guys,
just reading a book and saw pictures of TCP and UDP headers. Whereas
the UDP header has a length field describing the length of the UDP
segment including data and header, I can´t see such a field in TCP.
Is this an error of the book or how does TCP determine the length of
the segment
