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)[reply]

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

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)[reply]

"Segments" redirection

The "segments" link goes to a disambiguation page, the relevant link on which redirects to this page. 67.185.99.246 19:16, 29 January 2007 (UTC)[reply]

ISO7816 APDU

APDU redirects here but the page says nothing about smart cards nor APDU. —Preceding unsigned comment added by 81.219.231.40 (talk) 00:01, 21 December 2007 (UTC)[reply]

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

Physical layer: symbol instead of bit

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)[reply]

OSI model bias

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)[reply]
