  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.
