Bandwidth-on-Demand Service
Bandwidth-on-demand service lets you configure additional dial-up lines for
A congested leased line.
A congested multilink bundle, which is a set of links between two peer
routers.
A congested dial-on-demand line.
When data traffic exceeds the capacity of a line or bundle, bandwidth-on-demand
service alleviates congestion by adding up to 29 dial-up lines. The router can then
provide a total of 30 lines for communication.
PPP multilink is the protocol that enables the router to use multiple dial-up lines
simultaneously to transmit data. The actual number of lines in a multilink bundle
depends on hardware platform constraints, total speed of the group, the speed of
each link, and the type of traffic you are sending.
Enabling Bandwidth-on-Demand Service
The leased line, demand line, or leased multilink bundle is the physical connection
over which the leased or demand circuit, the logical connection, carries traffic.
The procedure for enabling bandwidth-on-demand service differs for leased
circuits and demand circuits.
For a leased circuit, you select the Bandwidth on Demand option from the Dialup
menu and designate the circuit as a bandwidth-on-demand circuit (herein referred
to as a bandwidth circuit). This designation tells the router to provide secondary,
dial-up lines if the leased connection become congested.
For a demand circuit, the Demand Circuits window includes a BW on Demand
button that lets you associate the demand circuit with an existing
bandwidth-on-demand pool. It also lets you configure bandwidth-on-demand
monitor parameters that determine when the demand circuit is congested.
Note: Refer to “Adding Bandwidth for Demand Lines” on page 1-6 for more
information about bandwidth-on-demand service for demand lines.
