The Bandwidth on Demand (BOD) service model supports services such as the remote backup of data servers, daily transfers to update web content, on-demand distribution between video servers and on-demand distribution of events, but it also supports carrier's carrier services. These connections fall into the category of switched connections and can be more dynamic than permanent connections while also having shorter holding times. With the PPB model, the user is required to pay the cost of the connection independent of the usage of the connection. In current data private-line services, the average utilization rate is low, and most of the bits go unused as a result of underutilization after hours and on weekends. While offices may be closed in the evenings and non-week days, the user still pays for the PPB connection. With the BOD model, service providers have the ability to take down a user's connection when it is unused and restore it when the next business day begins.

BOD service focuses on customers, such as ISPs, large intranet, and other data and SDH/Sonet networks requiring point-to-point capacities and dynamic demands, customers supporting UNI functions in their edge devices.

The time needed to set up bandwidth on demand can be less than only a few minutes. Equipment throughout the network can be set up automatically upon service request while the BOD service request would be completed only if the request is consistent with the relevant SLA and Bonus Circuit's policies, comes from an authorized customer, the network can support the requested connection, and the user edge device at the other end point accepts the connection.
