Serial Backbone

• Daisy chain link series of devices

- have some switches often connected in daisy chain to extend a network

- extent to which hubs can be connected is limited

Collapsed Backbone

A network configuration that provides a backbone in a centralized location to which all subnetworks are attached

Distributed backbone

A backbone network can consist of a number of connectivity devices connected to a series of central connectivity devices such as hub switches or router

Parallel backbone

Each switch and router are connected by two cables by having more than one cable connecting each device it ensures network connectivity to any area of the enterprise wide network
