Despite the ever increasing bandwidth of DSL connections, these remain the communications bottle-neck. In some cases it can be advisable to combine multiple DSL connections.
- Load balancing Load balancing dynamically divides TCP connections between independent DSL connections. The user has access to
the sum of the bandwidths of the bundled channels, although each individual TCP connection is limited to the bandwidth of the DSL
connection assigned to it.
- Indirect bundling for LAN-LAN links With indirect bundling, a PPTP connection is established on each of the two or more
independent DSL connections. These PPTP connections are then bundled. For LAN-LAN links at least, genuine channel bundling is
possible over the Internet even if the Internet provider itself does not offer channel bundling.
