Talk:User Datagram Protocol

What happens if a send of an UDP datagram is requested while the length is larger than the current MTU? Is the packet dropped, truncated, or split? Is it reassembled at the receiver end?
Answer: The network layer protocol (IP) will fragment the datagram and send it in separate pieces that fit within the MTU. Normally the receiving station will reassemble the fragments.
confusion
"In the TCP/IP model, UDP provides a very simple interface between a network layer below and an application layer above." yo Now wait aminute: is UDP part of TCP/IP? If so, it could stand more explanation. If not, perhaps the above should be re-worded. My guess is that you wanted to say something like: 'UDP and TCP are both transport protocols, either of which could be run over IP'. hjj
Concurrence
I too agree with the confusion over the first sentence. It should be ammended. UDP is NOT part of TCP..It is a separate entity. In fact, this article makes no reference to "connectionless". It is the distinct difference and counter point to the "connection" oriented TCP.
Re: confusion/concurrence
Added a link to Internet protocol suite, that explains why UDP does belong to the TCP/IP model. For short, the TCP/IP model is a layer model. Many protocols fit into the layers. One of them is UDP; another is ICMP. Both are part of TCP/IP. --200.208.45.2 22:31, 22 Apr 2005 (UTC)
