Talk:Protocol data unit/Archive 1

TPDU
I relocated the content from TPDU (finance) and linked that article here. I had posted this source for expansion in that article's talk page, so it will probably be useful here. BTW, I'm not sure if there's two TPDUs, one in which the T stands for "transaction" and another one in which it stands for "transport", or they're both the same thing. Anyone? --uKER (talk) 20:16, 3 July 2017 (UTC)


 * Hard to say what TPDU (finance) is since there are no refs and no incoming wikilinks. Maybe this? ~Kvng (talk) 14:00, 6 July 2017 (UTC)


 * I have created a new Transaction Protocol Data Unit stub article with refs cited above. I have modified TPDU and TPDU (finance) to point there. I can't find any reliable information about Transport protocol data unit and the information in this article is nonspecific and uncited so I have removed this section. ~Kvng (talk) 14:10, 6 May 2019 (UTC)

December 2019 Addition
added information to this article yesterday and also several other articles I follow recently. I believe that the user has clear expertise in the subject area but is new to Wikipedia, and the addition here is problematic in a similar way to some other edits. The text inserted reads:

"When aggregated into linking protocol batches, protocol data units are reconfigured based on the specific framework algorithm. Retrieval issues are prevented by cross-layered data reformatting systematics inherent to the protocol function, effectively securing packaged protocol data units from potential corruption incurred in transmission."

The problems I see with this are as follows:


 * 1) It is dropped into the middle of a description of a PDU and breaks the flow of that description which was written in a manner designed to help a layman as well as a technical reader to understand the concepts. This therefore causes problems of clarity;
 * 2) It introduces cross layer discussion that is unnecessary here;
 * 3) I find the English a little opaque. I can try to copy edit that, but not entirely sure what the point being made is, so perhaps that can be discussed here; and
 * 4) Two sources were quoted. The first source does not verify because it links to a whole chapter entirely about TCP, and not about a PDU in general. It does not contain anything that supports what seems to be said here. The second source does not use the quoted page numbering so I cannot find the pages referred to.

I would delete the whole thing, and have done so for some other of this user's contributions elsewhere, but there are positives here too. The editor has provided sources for a page that was distinctly lacking sources, and I think has valuable expertise too. So instead of deleting, I am hoping we can get some discussion here and find a way to focus the contributions in a way that enhance the article for readers. I have, however, flagged the section for clarity and marked the sources to show there are problems to resolve. -- Sirfurboy (talk) 07:53, 29 December 2019 (UTC)

ETA: OK belay all the above. I just noticed that the user Cunnfum has been blocked indefinitely as a sockpuppet. I have therefore simply deleted the problematic edit. -- Sirfurboy (talk) 08:13, 29 December 2019 (UTC)

Diagrams
Some diagrams might make this article more accessible. In networking books they usually show different layers and how a PDU goes on each one. Gravix 01:05, 1 September 2007 (UTC)

No word "datagram" found in article

 * It's related to "network packet". Logictheo 09:35, 3 October 2006 (UTC)

Fragments - click. Relevancy? --165.173.14.76 00:51, 14 December 2006 (UTC)

In the TCP/IP Guide (online version available for free here http://www.tcpipguide.com/free/t_MessagesPacketsFramesDatagramsandCells-2.htm), they say that "datagram" also refers to a PDU of higher levels instead of "data" like this very article is saying. Could someone clarify? Bragador (talk) 19:29, 31 July 2009 (UTC)


 * Article currently says ...the User Datagram Protocol (UDP) uses datagrams as protocol data units for connectionless communication. More content in brings it home, I think. ~Kvng (talk) 19:22, 3 April 2020 (UTC)
