Diffserv and IRTF defined dscp points.

Discussion in 'Windows Networking' started by John Barberio, Mar 29, 2005.

  1. Hi,

    After reading over the various IETF documentation of diffserv, I am
    confused by the Microsoft implimentation.

    The GQOS apears to define a use of the dscp field that is contrary to
    the intended use specified by the IETF. And most notably, one of the
    Microsoft defined dscp marks conflicts with an IETF defined mark.
    (Controled Service vs AF22 which is a 'medium' trafic clasifier, refer
    to documents at http://www.ietf.org/html.charters/diffserv-charter.html)

    I can so far only come to the conculsion that the Microsoft
    implimentation is not diffserv compliant? This is causing problems for
    me in setting up trafic filters for a router with mixed OS hosts.

    Is there any way to configure XP/200x to use the correct IETF dscp
    marks? Or a reliable way to identify and convert dscp fields using
    GQOS marks?

    - John
