Re: Network Models

I'm not really sure what you are asking... TCP is naturaly simpler
than the full OSI model, having only 4 layers. An application
built on top of TCP implements the higher OSI layers itself.

Hi
I am not talking about the layers. They have the same layers adopted from
the OSI Reference Model (that u mentioned in Wiki Pedia) but what i want
to
ask is that they have given this model a new name.
What i want is that TCP/IP model (DoD Model) is also a model other than
OSI
refence model.
Thanks for ur Help
Bye

Well, at least the wikipedia link clearly shows that the TCP
protocol which is on the top of the TCP stack (along with UDP)
is at layer 4 in the OSI model. Not sure how could you have
interpreted this wrong...

Hi
U are saying that there is no such model but when i searched it
showed
me
the TCP/IP model with 5 layers (Layers 1,2,3,4 and 7 of the OSI
reference
model).
the reason to ask is, just to have the confirmation of related work.
Rest what alexander and arkady mentioned is ok.
Thanks for the help

Parts of the ISO model reside within client applications. It's
a reference model after all - an abstraction. TCP/IP only
reaches the protocol level 4 in ISO - transport. For example,
a web browser (an HTTP client) contains a level 5 (session),
level 6 (translation), but no level 7 (application). For
comparison,
a simple HTTP client that only uses HTTP to download a single
file from a web server ony reaches level 5 - session. And as yet
another example, an AJAX application running within a web
browser would reside on level 7 - application layer.

Hi
that is ok but i am talking about the ISO Refeence Model and
TCP/IP
Model
in
which there are different layers (7 and 5). These models are
either
standards
(on which different suites are based) or we can say them Network
models
to
bulit up a suite.
--------------------------------------------
What is difference between suite and Stck.
Stack : Software implementation

Please clear these as well
--------------------
Suite : Definition (what is meant by definition)

Hi
1) i want to to know about network models. are there two
network
models
a) TCP/IP Model
b) ISO Reference Model.
am i right?????

IP is layer 3 of ISO and TCP is layer 4

2) Whats the difference between TCP/IP Suite and TCP/IP
Model.
3) Whats the Difference between TCP/IP Suite and TCP/IP Stack.

Microsoft TCPIP stack include not only tcpip.sys ( protocol
driver )
but
also all set of user mode dlls : winsock ( ws2_32 and mswsock )
,
msafd.dll
and kernel part including afd.sys , tdi.sys
which now ( in Vista ) used only for compatibility with old apps
and
now
kernel sockets used instead

Arkady

Plase clarift the points 2 and 3 with a bit explanation becaus
they
are
confusing me.
Thanks in advance
Bye
