Traffic shaping on non dedicated link

  • Just a quick question, has there been any new developments / discoveries (new algorithms etc) regarding effective traffic shaping on a non-dedicated link ( eg Comcast with burst ), in the last couple years?
    From before I remember that you had to choose to either limit peak bandwidth or the effectiveness of the algorithms would be effected (because actual bandwidth available at a given moment is difficult to know).

    Its been a while since I looked.
