OSI Model Transport Layer PDU #1

Open johnsoga opened 3 years ago

johnsoga commented 3 years ago

Looking at the the standards for the OSI Model in general it doesn't seem to define any specific PDU standards, they're more generalized. I think most of the PDU's used in the diagram inherently come from the TCP/IP Model and just get lumped together as OSI standards as clearly the TCP/IP protocols are the most widely used. Unfortunately, the PDF's of the standards seemed to be scanned without OCR so I can't say I read every page, so much as more so glanced through them; so I certainly could be wrong. But, if I'm not, you clearly identify the PDU's for layers 2 & 3. So you might want to mention that Segment and Datagram are in fact the PDU's for layer 2 using the definitions you are using.

This is really just a suggestion as someone who has no illustrator skills themself and so I can't make a diagram as nice as yours. So as someone studying for network certs thought I might call it out as I very much so do enjoy your diagrams. Cheers!
