Is the NFS in the Layer 7 (application layer) ?
|
|
|
| I found that the NFS is in the layer 7 and layer 5, but I do some tests, they don't consider the NFS is in the layer 7 just in the layer 5. | |

(i just came across it half an hour ago funny enough) its on the session layer. | |

| hhmmmm?
Correction to my last statement, I have now found it mentioned in the same ICND course as residing in the Application layer. I know SPX resides in two layers, can NFS reside in two layers?
Good question. | |

| I have the same question
NFS is network file system in the UNIX world
Normally is an application that runs on your PC to access Unix file systems
but the internal process to connect to it goes to layer 5 session in order to stablish the session ...
But I guess there is a different name for this ??but I dont know I think A UNIX guru will have the answer ! | |

| answer your question. I found this article
on the Cisco web site which gives a good simple explanation:
http://www.cisco.com/warp/public/78...6-training.html
According to Cisco NFS is an OSI Session layer protocol (Layer 5). But according to the TCP/IP model NFS is in the application layer. Learn both OSI and TCP/IP models
inside out and especially up and down! And
always remember that the correct answer is always "according to Cisco".
Hope this helps! | |

| There are two types of NFS and as stated above one is for windows to unix file sharing which sits at the application layer and the other is the network version which sits in the session,or something like that, its all gone dark! |
