Specialist - Circuit Bonding Overview

Bonding is the term given to aggregating 2 or more ‘slow’ circuits to give the performance of one ‘fast’ circuit.

Circuit or Broadband Bonding is more commonally performed with ADSL but can be done with SDSL or even 3G.

Consider Bonding if your business is a great distance from the exchange or you want increased upload speeds.

If your business is on the furthest reaches of the network, Broadband Bonding maybe for you. The main drivers are excessive distance from the exchange or connection to a rural exchange lacking any of the more advanced services. Either way single channel DSL isn’t delivering the goods.

Broadband Bonding works by aggregating multiple low speed circuits to give the performance of one faster circuit. There is of course a small Bonding overhead but 2 circuits should deliver at least 1.9 x the speed of a single circuit.

Although the technology exists to Bond 16 or more circuits the bulk of the market concentrates on to 2-4 circuits. In the illustration above 4 ADSL Max Premium Circuits are Bonded to provide theoretical speeds better than is possible on any single DSL circuit. However, if you are not close to the exchange, a more realistic example would be Bonding 4 circuits with real world speeds running at 2Mb down and 0.5Mb up to achieve 8Mb down and 2Mb up.

If the only other options are expensive Fibre Ethernet Leased Lines or relocating your business then Bonding can seem very attractive!
