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[edit]

What is a datagram? Mathiastck 22:49, 9 August 2006 (UTC)

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

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

In the TCP/IP Guide (online version available for free here, 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)

"Segments" redirection[edit]

The "segments" link goes to a disambiguation page, the relevant link on which redirects to this page. 19:16, 29 January 2007 (UTC)

ISO7816 APDU[edit]

APDU redirects here but the page says nothing about smart cards nor APDU. —Preceding unsigned comment added by (talk) 00:01, 21 December 2007 (UTC)

Smart card APDUs aren't the only types of APDUs in existence. Guy Harris (talk) 00:17, 21 December 2007 (UTC)

Physical layer: symbol instead of bit[edit]

Shouldn't the PDU of the physical layer be the 'symbol' instead of the 'bit'? Most times bits are not transmitted individually if I'm not mistaken. Qorilla (talk) 11:30, 31 May 2010 (UTC)

OSI model bias[edit]

The TCP/IP model is under-represented here. With Internet Protocol as dominant as it is, doesn't pdu deserve to be shown in this light as well? Stephen Charles Thompson (talk) 20:02, 24 January 2012 (UTC)


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)
