What is Bonded DSL?
Put simply, Bonded ADSL or SDSL (collectively DSL) is where multiple broadband lines are joined together to form a single larger pipe.
Mature technology
The industry standard way of achieving this is through the use of MultiLink PPP (MLPPP). This is a tried and tested technology and has been used by Internet Service Providers for many years. It is the very same technology used to provide ISDN internet connections larger than 64k.
Whereas with ISDN multiple 64k channels could be combined to make a larger (128k or 256k) connection, with DSL we are combining multiple high-speed ADSL or SDSL lines.
Required Equipment
Ordinary consumer ADSL and SDSL routers are not capable of bonding DSL lines. A more sophisticated router such as Cisco or FireRack is required to perform line bonding.
Some Virtual Internet Service Providers (VISPs) claim to provide a bonded DSL service without utilising MLPPP. Typically the technique that they use is to bond multiple VPN connections together, rather than bonding multiple DSL lines. This is not true line bonding and is a technically inferior solution with a number of disadvantages.
