Note: This version of channel bundling provides bandwidths that are a mul-
tiple of the smallest bundled channel. This means that it is especially effi-
cient when channels are all of the same bandwidth. The direct bundling of
different bandwidths means that the channels with the higher data rates
suffer from a loss in effective bandwidth.
When bundling MLPPPoE for DSL channels behaves in the same way
as the well known MLPPP for ISDN channel bundling.
D Load balancing
Load balancing involves the dynamic division of TCP connections
between independent DSL connections. The user has access to the sum
of the bandwidths of the bundled channels, but the individual TCP con-
nections are limited to the bandwidth offered by the DSL connection allo-
cated to it.
Note: Unlike direct channel bundling, load balancing offers the true sum of
all bundled bandwidths. This version is thus highly effective for combining
different bandwidths.
