A collapsed backbone, compared to a distributed backbone, is one in which the backbone network is collapsed into a single high-performance node that is normally centrally located. Contemporary routers are getting increasingly intelligent. They can collapse one or more distributed networks into a single device, and enable a high-speed pathway between them (i.e., a backbone). Collapsed backbones can provide highly reliable throughput with transmission speeds in excess of 1 gigabit per second.

The advantages to the use of a collapsed backbone are lower cost of electronics in remote wiring closets, higher speed (1 gigabit-plus), inherent support for bridging and routing across the backbone, more efficient use of fault tolerant hardware (centralized versus distributed), enhanced security (centralized versus distributed), better support for token ring connections to the backbone where required, and easier transition to ATM (centralized versus distributed).
