Talk:Frame (telecommunications)

From Wikipedia, the free encyclopedia

Can one define what a HTML frame is ??. Thanks in advance Mac 00:25 Mar 12, 2003 (UTC)

It's a method for dividing a web page into multiple independent regions. See this introduction. Since I've turned the base Frame article into a disambiguation page, they should be described at Frame (HTML). They're somewhat controversial, as most implementations tend to give poor user experience.

Cartan's frame isn't *really* a basis of the tangent bundle. That's a misunderstanding of what a frame really is! Phys 20:44, 2 Nov 2003 (UTC)

I don't see any entry for the notion of "frames" as a data structure used in knowledge bases such as Protege (http://protege.stanford.edu). There is an entry for "the frame problem in artificial intelligence, a data structure ...", but the page in question never talks about frames as a data structure. The entry that starts "Semantic frames in cognitive science" also looks promising, but it leads to a page on "Framing (communication theory)".

The AI Dictionary (http://www.cse.unsw.edu.au/~billw/aidict.html) has an entry which might be a good starting point. The Generic Frame Protocol page (http://www.ai.sri.com/~gfp/) also contains some useful information.

[edit] I think the picture is confusing

I think the picture of the way NASA used frames in its deap space network is a little to specific and confusing as to how packets work -in general via: "This process involves, at a minimum, adding delimiters to distinguish the packet from dead air". Can it be removed? It made me think -packets are always the same size. And I don't think that's true now.

[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?
  • And what is NASA doing in the middle of this :) ?
  • What is dead air?

I believe this article needs a total makeover, untill then stick to the article [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.
(also, the NASA image discussed above was removed at some point, but it may still be marginally helpful) --Twinkie Assassin (talk) 17:18, 13 February 2008 (UTC)
