What Internet "Speed" Really Means

We all want to go fast, especially on the internet, but so many consumers are misled everyday by the advertisements of service providers.

When they [Cable Company, FiOS, Whoever] say that they're the fastest, they really mean that their service has the most capacity. On a network, speed means how long it takes for a signal to go from your end of a network to another. The technical term for this is latency, measured in milliseconds.

The service providers are actually describing capacity, measured in Megabits (Mbps) or Gigabits (Gbps) per second. What this means is you have a connection that allows for a lot more traffic before it gets bogged down. Think of a 6 lane highway.

Depending on your needs, you may want lower latency instead of higher capacity. If you have a web server, lower latency is better when you have many small pieces to transmit. An FTP server is completely different because you would want to move those large files in less time or be able to handle more transfers at one time. With the FTP server, how long it takes to make the connection isn't as important as how much data it can move when there is a large volume of data to move.

Here's an easier way to understand it...

Latency:
You need to deliver a letter (small files like a webpage) to someone across the country. Low Latency (fast) means you hop into a Formula 1 racecar and zip it across the country. If you need to transport many letters, this connection is great. This would be a T1 or other dedicated connection.

Capacity:
Now while the race car is fast, it can't carry large packages or freight (big files on an FTP Server), therein lies the problem. Here you would use a slightly slower connection (an 18 wheel truck) , to handle much more in one delivery. It takes longer but if you are moving many large files or have many people to deliver to, you want more capacity, speed isn't as important.

Common Connection types:

• T1/metro Ethernet - fast (private highway for your files), expensive, corporate grade, guaranteed speed and up-time metrics
  
• Cable Internet - "slow", but has a lot of capacity shared across subscribers, no service up-time guarantee, cheap
  
• FiOS (Fiber) - faster than cable, has much more capacity than cable, but no service up-time guarantee, cheap

There are many other options, but for the small business, it really comes down to these 4.

Depending on your internet usage needs (web server, e-mail, FTP, VoIP) having a cable/fios connection may not be the best solution.

We've helped countless companies measure their needs with the connectivity they really need, not just what they've seen on TV.
