Talk:Network layer

Difficult to understand the concept
To someone who doesn't do this for a living, this article does not make a god damn bit of sense. 169.237.97.212 19:43, 26 January 2007 (UTC)

Conflicting statements
There are conflicting statements:
 * The Network layer performs network routing, flow control, segmentation/desegmentation, and error control functions.

and
 * However, it does it in a very basic way, without error detection or flow control

Can somebody please clean this up? Colin Marquardt


 * Additionally, it is stated that the network layer "manages traffic problems, such as switching", but in the Network_switch article it says that "A switch can connect (...) network segments together to form a heterogeneous network operating at OSI Layer 2" (data link layer). So, in which layer does switching occur? Azrael81 03:36, 29 September 2005 (UTC)

ICMP
Why is ICMP put in the "network layer" section? There are a lot of other mistakes too. —Preceding unsigned comment added by 80.98.250.126 (talk • contribs) 18 August 2005


 * ICMP is part of the (so-called) network layer. (It should be the "internetwork layer", but the stupid 7-layer model doesn't have one.) It is carried on top of IP, yes, but its functionality (error messages, etc) is part of the internetwork layer. Noel (talk) 15:26, 14 September 2005 (UTC)

References missing
The knowledge shared is well-known and widely considered common basic knowledge in the computing world. Still, for someone out of the context, shouldn't the article cite its references? —Raanoo 10:16, 6 September 2006 (UTC)

TCP/IP model
The TCP/IP model article referenced describes only four layers, not five...

-It talks about four layers originally, but then says that the "the model has evolved into a five-layer version that splits Layer 1 into a Physical layer and a Network Access layer" although that could use cleanup. I've fixed the comment to refer to the correct layer in the five layer version. Egret 00:01, 1 July 2007 (UTC)

Formatting askew
The formatting of the text near the TCP/IP stack template is messed up in Firefox. But darned if I can fix it. Anybody? Egret 07:41, 11 August 2007 (UTC)
 * Fixed by Adrian by moving one of the templates down. Thx Egret 04:30, 12 August 2007 (UTC)

Move discussion in progress
There is a move discussion in progress which affects this page. Please participate at Talk:Physical Layer - Requested move and not in this talk page section. Thank you. —RM bot 03:45, 19 October 2011 (UTC)

Services and Functions incomplete, contradiction with hierachical network addresses
What is most missing in this article for me is a more detailled list of functions and services that are performed by the network layer.

Furthermore, there is a contradiction with the main article about the OSI Reference Model "This is a logical addressing scheme – values are chosen by the network engineer. The addressing scheme is not hierarchical." this article however, points out the following: "This address is normally assigned from a hierarchical system."

I hope there is an expert who can fix this confusion.

Thanks Lukas

Strange table / advertising inserted in prolog
Before the table of contents an IP-addressed user added a table that seems like advertising.
