Hello, I am working on implementation of TDM over MPLS. The current MPLS implementations "inserts" a mpls label to the normal TCP-IP packet keeping the TCP/IP stack intact in the packet. As per the protocol suit of TDMoMPLS, the TDM payload directly goes over MPLS shim with no TCP/IP stack. So I want something like a MPLS 'socket' as we have TCP/IP socket for network programming. Can anyone help me understand how I can achieve that by taking help of current MPLS-linux implementation ? Sorry if this is a repost, but I am not able to view the mailing list archives due to some problem at the sourceforge site's end. Thanks in anticipation. Medha |

Take a look at the code in my 'personal development tree':
http://mpls-linux.sf.net/
In particualr look at l2cc-kernel and how it implements L2CC_OPCODE_MPLS_TX.
It makes a call to mpls_output_shim() which calls into the MPLS stack
at the right place for a label shim to be pushed and for the resulting
packet to be TX'd.
What hardware are you using that will give you raw TDM data?

thanks a lot for help. since this is just start of the my project, i haven't really used a particular hardware for raw TDM data generation until now. my first priority is to get some data (even text data) across the network using only mpls shim w/o TCP/IP stack, and then replacing the text data with TDM payload.

my l2cc-kernel can do ethernet/ppp over MPLS. You will probably want to follow that model. What type of signalling do you plan on using? Martini? If so I'm in the midst of a re-write of ldp-portables FEC handling so it can deal with Martini FECs.

can u please make the files of l2cc-kernel and l2cc-linux available on sf or elsewhere ? the perforce isn't working as expectated (after the p4v command with needed options, it just hangs on command prompt. i doubt whether this can be attributed to IIT-B's firewall config!!??)

Thanks for helping keep SourceForge clean.
