If your company has Dedicated Internet Access and your ISP fails to meet its SLA, they will give you a monetary refund, based on the details outlined in your original contract.

Jitter (only guaranteed with some ISP’s).

Piggy-backing on the benefit of better throughput, (since DIA traffic runs over a better backbone network), ISP’s can also slap a snazzy guarantee on the quality of your Internet traffic, called a Service Level Agreement (SLA). With real-time applications like VoIP, Video and Remote Desktop growing in popularity, things like latency, packet loss, and jitter have become extremely important on your company’s Internet connection. Therefore, despite having the same circuit speed, a 100M Dedicated Internet Access connection will almost always be faster than a 100M inexpensive, shared Internet access connection. Shared Internet connections often run on jammed, over-subscribed backbone networks. ISP’s don’t advertise this but they keep their Dedicated Internet Access customers on a high-capacity, under-subscribed backbone network. The onramp might be huge and wide-open but if the freeway is packed with traffic, it’s going to take you a long time to reach your destination. The best analogy is a freeway onramp (i.e. Once your traffic hits the network, however, it only moves as fast as the network will allow.

It’s just the bandwidth at which the circuit accesses the ISP’s backbone network.

This is a little-known secret in the ISP world but as any ISP network engineer will tell you, the bandwidth your company buys is not the circuit’s actual throughput. If your company doesn’t have time for this kind of skulduggery, DIA might be the answer.

Has your company ever experienced slow Internet speed yet your Internet speed test says your bandwidth is high? For instance, it’s common to see an inexpensive shared Internet connection with a maximum download speed of 100M and a maximum upload speed of only 10M. Less expensive, shared Internet connections typically have a fast download speed and a significantly slower upload speed. If your company purchases a 100M Dedicated Internet Access circuit, both your download and upload speed/bandwidth are always guaranteed at 100M.įast upload speed is important if your company has a lot of remote users, cloud apps, VoIP, etc. With shared connections, the actual speed is unpredictable and fluctuates throughout the day, depending on the ISP’s network traffic. This is different than “shared” connections, where the speed your company purchases is the maximum speed you will receive. This is helpful because a company can decide on the speed they require, purchase it and rely on it to be the same speed, every minute of the day.
