[edit] Really confusing article
After reading this article I am really confused. I simply dont know what a frame is.
- It says that " (...) a frame is a packet (...)". To me it is not! And not according to the article about [packet].
- The illustration hints that frames are of fixed size, but the article does not say that. I also hints that a frame is definitely not a packet.
- And of what size is a packet?
I believe this article needs a total makeover, untill then stick to the article [packet].

[edit] Comparison to packet
It's not a reliable source, but this post offers a reasonably convincing explanation. It suggests that the term "frame" derives from framing bits used to demarcate a time slot during which a set of bits are sent. (it goes further, suggesting that a "frame" isn't really a frame once it's been statically captured, but instead "frame" only refers to a specific "time frame" during which a set of bits are sent). I won't add that in the article, since IANACCNA, and the article is already sorely lacking references for what's currently there.
- Anyway, the standard breakdown of:
- hub = layer 1 = sees things only at the bit-level
- switch = layer 2 = sees things only at the frame-level
- router = layer 3 = sees things only at the packet-level
- is clear enough at least. A frame is something that's closer to what's actually happening on the wire, but is higher-level than bit-at-a-time.

-- Dc sharp (talk) 19:09, 21 September 2011 (UTC) Agree- specifically with respect to mixing "frame" and "packet" -- http://en.wikipedia.org/wiki/Protocol_data_unit says that an OSI Layer 2 PDU is a "frame" and a Layer 3 PDU is a "packet". But then when you follow the link to this "frame" page, it says that a frame *is* a packet. Either this page needs to not equate packet and frame, or the PDU page needs to be updated.
-- The OSI model is not the end-all be-all definition of network architecture. Please consider the TCP/IP model as well. The current version of the network packet article is entrenched in OSI terminology, but needs to be revised to include TCP/IP definitions as well.

[edit] Multiple overlapping articles
We have at least four distinct articles covering the same basic topic:
While I appreciate that there may be technical differences between the different terms, I don't think we do readers a good service by having multiple articles on the same general topic. I don't feel so bold as to perform or formally propose a merge but I would like to discuss what we can do to improve WP coverage in this area. --Kvng (talk) 17:39, 3 February 2012 (UTC)
