Re: [mpls-linux-general] packet identification

[Muhammad R. S. <sa...@cc...>]

In reference to my previous mail, basically I want the ingress router to =
read specific information in the application layer header and then set =
EXP value and forward the packet. It is basically an If-Else situation:

 If this (in application payloiad) -> then EXP value =3D x
 else EXP value =3D y

Is this possible. If yes then please let me know how?
Looking forward for your kind cooperation.
regards

  There already exists some mechanisms for EXP setting.  Although there =
is
  probably area for improvment.  I should not that I have not tested EXP
  setting for about a year and a significant amount of development has
  occureded since then, so you may run into some bugs, if so let me know =
and
  I'll try and produce fixes.

  A quick overview of what you will need to setup:
  -bind a IPv4 route to a LSP
  -use iptables to identify and mark packets
  -use the markings to set EXP values (or choose differnt LSPs)
  -use EXP value to determin queuing priority
