Internet-Drafts are working documents of the Internet Engineering    Task Force (IETF), its areas, and its working groups.  Note that         other groups may also distribute working documents as Internet-   Drafts.        Internet-Drafts are draft documents valid for a maximum of six months    and may be updated, replaced, or obsoleted by other documents at any    time.  It is inappropriate to use Internet-Drafts as reference    material or to cite them other than as "work in progress."        The list of current Internet-Drafts can be accessed at         http://www.ietf.org/ietf/1id-abstracts.txt    The list of Internet-Draft Shadow Directories can be accessed at         http://www.ietf.org/ietf/1shadow-sites.txt         Abstract        This specification designs an architecture that aims at load    balancing flows along multiple routes according to a measure of their    average traffic loads.      This architecture supports such a service due to the operation in a    closed loop of an enhanced routing control plane with an enhanced    forwarding plane.    Basically, this routing paradigm allows a second dynamic metric    called load to be taken into account when calculating new routes and    when forwarding the flows along the routes.
