UDP and fragmentation

How does UDP handle fragmentation? In TCP you have fragment offset but nothing in UDP?

Re: UDP and fragmentation

Hello,

as far as I know fragmentation is managed at the IP level in the IPv4 header/ IPv6 header.

In the TCP header there are some fields like the urgent pointer but they are not related to IP fragmentation.

See http://www.wtcs.org/snmp4tpc/images/TCP-Header.jpg

So the answer is that it is IP not UDP or TCP that deal with fragmentation.

hope to help

Giuseppe
