MLPPPoE is used to bundle multiple DSL connections to a single provider. For example, two DSL 6000 connections can be bundled to form a (fictitious) DSL 12000 connection. This can be done by combining the integrated ADSL/VDSL modem with external DSL modems connected at the Ethernet ports.
Although DSL connections of different speeds can be bundled, each line is forced to operate at the speed of the slowest connection. Bundling a DSL 6000 and a DSL 2000 connection would only result in the bandwidth of a single DSL 4000 connection.
MLPPPoE is significantly different from the load balancing technology used in LANCOM routers. The load balancer, which combines the lines into a single remote site, distributes the load statistically. A session is randomly distributed to one of the lines defined in the load balancer. However, each session can only use the maximum throughput available on the respective target line. Using MLPPPOE, on the other hand, different lines are combined into a single entity, which provides the overall capacity of all of the lines.
