  1. I’ve been searching for an RSVP implementation for linux and haven’t had good luck. Any chance you have come across anything? It seems like there hasn’t been any work since 2000.
    Thanks!

  2. Great article again so clear… Thnx to you !

    As long as I read about that, we are able to implement QoS (DSCP or COS) mechanism for MPLS within EXP bits right instead of RSVP. How is the current MPLS network designs with QoS nowadays? RSVP is first precedence for MPLS ?

    Intserv (RSVP) isn’t used much to give packets a certain treatment, we use Diffserv (DSCP, COS, MPLS EXP bits) for this. The problem with Intserv is that it’s not scalable.

    In MPLS environments however, RSVP can be used for traffic engineering.
