Introduction

WAN Topologies

The P840 router may be connected to other P840 routers in two configurations: Multipoint or PPP Multilink. The WAN routing method used is set in the Remote Site profile defined in the Remote Site Set-Up Menu.

Multilink

In a Multilink configuration, two P840 routers are connected together with one or two WAN links. Each link may be set to an always active (unconditional) state or a backup/recovery (conditional) state.

A single link may be used for general traffic, and the second link may be used for increased throughput. The Bandwidth on Demand feature controls the conditional behavior of the second link in a Point-to-Point configuration.

The Time of Day connect feature may be used in a Point-to-Point configuration to provide specific hours of access or increased throughput.

Multipoint

In a Multipoint configuration, a P840 router is connected to more than one other P840 router. A Multipoint configuration consists of three or more P840 routers connected together on the same wide area network.

A dual-link P840 router that is connected to two different P840 routers (one on each link) is in a Multipoint configuration.

The Time of Day connect feature may be used in a Multipoint configuration to provide specific hours of access.

Bandwidth On Demand

Each P840 router has the ability to automatically enable or disable a second link based on traffic activity, or time of day.

The Bandwidth on Demand feature allows you to use a second link only when required, thus saving the cost of having the second link up and connected all of the time.

Bandwidth on Demand is accomplished by using the intelligence of the P840 to measure the utilization of the primary link. When it approaches saturation, Bandwidth on Demand will initialize and loadshare with a second stand-by link. This will effectively increase the throughput of the P840 router, thereby alleviating the saturation and avoiding data loss. The second link is then deactivated when traffic levels drop off to where the primary link can adequately handle the traffic load once again.

When the stand-by link is activated, the P840 router will establish the ISDN connection to the remote partner P840.

When the second link is deactivated, the P840 router will disconnect the ISDN call. The second link then remains in stand-by mode until the bridge/router determines that the link must be used again.
