[mpls-linux-general] Diffserv over MPLS for Linux.

[ncc49a <nc...@si...>]

Hi,

    I have got some queries regarding the  Diffserv implementation over MPLS
for Linux.

1)    For an egress MPLS node, an incoming MPLS packet may have its EXP
values "translated" into DSCP values via the
        exp2ds command, right? Is it used in a similiar way as ds2exp?
2)    How are the MPLS LERs and LSRs going to police the traffic based on
the EXP bits of the MPLS pkts passing through them? Is it via the exp2tc
command? Any examples of how to implement that?
3)    Haven't tried it yet, but can a packet have its DSCP marked by "tc"
and then its EXP bit marked by the ds2exp command on the same ingress node?

    Any further examples of DS over MPLS will be helpful!

    Thanks a lot!!

Regards,

Paul
