hierarchical routing
     
        the complex problem of routing on large networks can be
        simplified by breaking a network into a hierarchy of smaller
        networks, where each level is responsible for its own routing.
        the internet has, basically, three levels: the backbones, the
        mid-levels, and the stub networks.  the backbones know how to
        route between the mid-levels, the mid-levels know how to route
        between the sites, and each site being an autonomous system
        knows how to route internally.  see also exterior gateway
        protocol, interior gateway protocol, transit network.
