[ns] ... MPLS simulator

[Sahel Alouneh]

Hi all,
   
  I'm trying to build an MPLS network using ns-2. I want to write my own application that can process each packet at the ingress router of MPLS network. My application should do mathmatical process on every packet and after that the modifid packets can pass through the network.
   
  my question is if there is an MPLS network simulator , and if not, how can i build my application and how to connect to ns-2 ?
   
  or how can i implement my own encryption application into packets using ns-2?
   
  thanks in advance
   
  sahel
