network programing : How to program in 'logical link control (LLC)' level?

Post by Jang JaeI » Sun, 05 Apr 1998 04:00:00



Hi,

I must make a program which should network in LLC level (logical link
control-ieee802.2) on ethernet (in linux ).
I don't know how to do - which library, system call, API, examples... I
should use.
In kernel source directory /usr/src/linux/net, there is 802, ethernet
dir. - Shell I use it?
I have no infomation about LLC level progrming  in linux. Does anyone
give me it?

T.I.A.

1. LLC( Logical Link Control ) level networking , programing in linux ?

Hi, all

I have some program which runs in solaris5.1.1 & networking in
LLC level(IEEE802.2) using DLPI( Data Link Provider Interface )
of AT&T.
It has to use DSAP( Destination Service Access Point ),
SSAP( Source Service Access Point) field & control field.

ex.) IEEE802.2 format in IEEE802.3
       +------------------------+
       |     Preamble           |

       |  Destination Address   |
       +------------------------+
       |      Source Address    |

       |         Length         |
       ~                        ~
       +------------------------+    <---+
       ||        DSAP          ||        |
       +------------------------+      LLC PDU
       ||        SSAP          ||      (Protocal Data Unit)
       +------------------------+        |
       ||        control       ||        |
       +------------------------+    <---+

       ||                      ||
       +------------------------+
       |  Frame Check Sequence  |
       +------------------------+

May I control LLC PDU in linux ( in user level not kernel..) ?
That is, it must be able to set DSAP SSAP control field - like DLPI of
solaris..
