The majority of Cable DOCIS, DSL, FTTH and Satellite rely on shared resources throughout the system.These networks can be impacted by network congestions and the actual speed can be unpredictable and fluctuates throughout the day.Shared connections are dependent on the ISP’s network traffic.
Less expensive, shared Internet connections typically have a fast download speed and a significantly slower upload speed. 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.
These networks are “Over-Subscribed”
Dedicated Internet Access (DIA)
Dedicated Internet Access (DIA) is different than “shared” connections.The speed your company purchases is the maximum speed you will receive. DIA Circuits are necessary for many large organizations that rely on file transfers or cloud applications.
Some applications require Synchronous upload and download speeds and if your company purchases a 100M Dedicated Internet Access circuit, both your download and upload speed/bandwidth are always guaranteed at 100M.
Fast upload speed is important if your company has a lot of remote users, cloud apps, VoIP, Offsite Backup, etc.
Service level agreement
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.
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).
A typical DIA SLA will guarantee:
4.Jitter (only guaranteed with some ISP’s)
Guaranteed Response Time Available
