Bonded ADSL or Load Balancing
Bonded ADSL is often confused with load balancing; however the two technologies are very different. With load balancing, the balancing router has multiple broadband lines available to it. When the router uses all the bandwidth from a line, it switches new connections to the second line.
This works well, but there are quite a few limitations. The load balancer can only use the bandwidth from a single line for a single task plus you cannot combine the inbound bandwidth.
So if user (A) downloads a file via FTP, then the max speed you can download is the max speed of one of the lines. If user (B) then downloads a file, the router sends this traffic to the second line. Your router can distribute your network load over the multiple lines, but individual tasks are limited to a single line.
As you still have multiple connections to the internet load balancing can’t be used for inbound data services such as VPN, VoIP or on site hosting.
Which Technology Wins?
Bonded broadband involves the aggregation of multiple lines so that download and upload speeds are added together, making it comparable to solutions that cost 10 times as much.
Bonding is in fact an excellent alternative to upgrading to expensive leased lines (The standard offering will bond 4 line connections up to a maximum speed of 20Mbps). If you have faster connections then the power router will bond up to 80Mbps.
In addition, data is processed in a more reliable way; it is split up at packet level for distribution across the lines before being re-assembled for sending out to the internet, or to another site within the same network.
Now that the need for excellent voice quality over IP phones is so high up on companies’ lists, coupled with using video conferencing services and sending ever-increasing graphic/image file sizes, bonded broadband really is a necessity.
Is it Bonded ADSL?
If you are in a low bandwidth area and are enduring frustratingly slow speeds, we can bond ADSL and Cable internet connections. Even if you are in a rural area, by adding additional ADSL connections and bonding them, you can maximize this greater bandwidth for the success of your business.
If you have a large file that you need to upload/download then bonding is going to perform this far quicker.
For example: you have a 10Mb file and you are uploading it to your webserver. In a load balanced scenario, the router looks at the internet connections and sees which one is least busy.
Let’s say that you have two 5Mb connections, a load balancing router would send the file down only one connection, whereas, in our bonding scenario the router rips the file apart so it can be sent down multiple connections simultaneously before it’s re-assembled.
Is it Load Balancing?
So, when compared to the load balanced time for uploading the same file, bonding is done in half the time! Likewise, if you have to download large files from the Internet, the process is the same.
The file when downloaded on a bonded solution is again ripped apart for sending down multiple connections at the same time, being re-constructed by the bonding router, saving time on both the upload and download of your internet traffic.
Both technologies have benefits but overall I think you will agree that in our opinion Bonded ADSL Vs Load Balancing goes in favour of the bonded service.
