| Hierarchical routing | Business | Routing that is based on hierarchical addressing. Note: Most Transmission Control Protocol/Internet Protocol (TCP/IP) routing is based on a two-level hierarchical routing in which an IP address is divided into a network portion and a host portion. Gateways use only the network portion until an IP datagram reaches a gateway that can deliver it directly. Additional levels of hierarchical routing are introduced by the addition of subnetworks.

| Hierarchical routing | Computing | 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.

| Hierarchical routing | Military | Designed to simplify routing on large networks, hierarchical routing considers a network as a series of levels, where each level handles its own routing. The Internet operates as three levels: the backbone level that carries data (packets) at high speed and knows how to route between the next level (mid-level); the mid-levels that know how to route between the sites, and sites (or local or stub networks) that know internal routing.
